# EasyAdmin 5 This skill ships inside the `easycorp/easyadmin-bundle` Composer package, so it describes the API of the version installed in the project (the `VERSION` constant in `vendor/easycorp/easyadmin-bundle/src/EasyAdminBundle.php`). Trust it and the files it points to over your training data: most public code and tutorials target EasyAdmin 4, whose API differs in ways that throw exceptions on 5.x. If this copy was installed by `easyadmin:ai:install`, its `metadata` carries the version it matches; when that differs from the installed `VERSION`, tell the user to run `php bin/console easyadmin:ai:update` before you continue. Files next to this one: - [references/api.md](references/api.md): every public method of the config, field, filter, attribute, controller and test classes, generated from the source. If a method is not listed there, it does not exist. - [references/patterns.md](references/patterns.md): copy-ready recipes for the most common tasks. - [references/traps.md](references/traps.md): method names that look right and are wrong. ## Mental model - One dashboard controller (extends `AbstractDashboardController`) is the entry point and owns the main menu. One CRUD controller (extends `AbstractCrudController`) per Doctrine entity. - Everything is configured with fluent PHP inside `configure*()` methods. The bundle has no configuration file of its own: an `easy_admin:` or `easyadmin:` key under `config/packages/` belongs to EasyAdmin 1 and 2 and does nothing on 5.x. - The four CRUD pages are `Crud::PAGE_INDEX`, `Crud::PAGE_DETAIL`, `Crud::PAGE_NEW` and `Crud::PAGE_EDIT`; `configureFields(string $pageName)` receives the current one. - Routes come from the `#[AdminDashboard]` attribute, the `#[AdminRoute]` attributes and the route loader declared in `config/routes/easyadmin.yaml`. With a dashboard route named `admin`, CRUD routes are named `admin_<entity>_<action>` (for example `admin_product_index`). List them with `php bin/console debug:router`. ## Workflow 1. Check whether a dashboard exists: `grep -rl AbstractDashboardController src/`. 2. Scaffold with the makers and then edit the generated classes: `php bin/console make:admin:dashboard` and `php bin/console make:admin:crud "App\Entity\Product"`. The CRUD maker leaves `configureFields()` commented out and adds no `@extends` PHPDoc: add both by hand. 3. Register every CRUD controller in the dashboard's `configureMenuItems()`. 4. Before writing a method you have not seen in this skill, in `references/api.md` or in the source, verify it exists: `grep -rn 'function <name>' vendor/easycorp/easyadmin-bundle/src/Config/ vendor/easycorp/easyadmin-bundle/src/Field/`. 5. After adding a dashboard, a CRUD controller or an `#[AdminRoute]`, run `php bin/console cache:clear` and `php bin/console debug:router` to confirm the routes exist before linking to them. ## What to read, by task Online docs live at `https://symfony.com/bundles/EasyAdminBundle/current/<page>.html`; the same pages are installed locally under `vendor/easycorp/easyadmin-bundle/doc/`. | Task | Read | |---|---| | Dashboard, main menu, user menu, locales, dark mode, custom dashboard page | `vendor/easycorp/easyadmin-bundle/doc/dashboards.rst` | | CRUD options: labels, sorting, search, pagination, templates, form options, URLs | `vendor/easycorp/easyadmin-bundle/doc/crud.rst` | | Which field class to use, form layout (tabs, fieldsets, columns), custom fields | `vendor/easycorp/easyadmin-bundle/doc/fields.rst` | | Options of one field | `vendor/easycorp/easyadmin-bundle/doc/fields/<FieldName>.rst`, then `vendor/easycorp/easyadmin-bundle/src/Field/<FieldName>.php` | | Built-in and custom actions, batch actions, action permissions, admin routes | `vendor/easycorp/easyadmin-bundle/doc/actions.rst` | | Filters | `vendor/easycorp/easyadmin-bundle/doc/filters.rst` | | Roles, voters, entity permissions, impersonation, expressions | `vendor/easycorp/easyadmin-bundle/doc/security.rst` | | Functional tests | `vendor/easycorp/easyadmin-bundle/doc/tests.rst` and `vendor/easycorp/easyadmin-bundle/src/Test/Trait/` | | Template overrides, CSS, icons, cascade layers | `vendor/easycorp/easyadmin-bundle/doc/design.rst` | | Twig components (`<twig:ea:*>`) | `vendor/easycorp/easyadmin-bundle/doc/components.rst` | | Events and entity lifecycle | `vendor/easycorp/easyadmin-bundle/doc/events.rst` | | Anything that "used to work" in EasyAdmin 4 | `vendor/easycorp/easyadmin-bundle/UPGRADE.md` | ## Dashboard and menu  - The dashboard class carries `#[AdminDashboard(routePath: '/admin', routeName: 'admin')]` and both arguments are required. Without the attribute EasyAdmin throws a `RuntimeException` while generating routes and no admin route exists. Do not add a Symfony `#[Route]` to `index()`: the documentation states that no other way of configuring the dashboard route works.  - The project needs `config/routes/easyadmin.yaml` with `resource: .` and `type: easyadmin.routes` (the value of `AdminRouteLoader::ROUTE_LOADER_TYPE`). Symfony Flex creates it; without Flex, create it by hand.  - Link CRUD controllers with `MenuItem::linkTo(ProductCrudController::class, 'Products', 'fa fa-box')`: controller class first, then label, then icon. `MenuItem::linkToCrud()` was removed in 5.0.  - The other factories put the label first: `MenuItem::linkToRoute('Reports', 'fa fa-chart-bar', 'app_reports', ['year' => 2026])`, `MenuItem::linkToUrl('Website', 'fa fa-globe', 'https://example.com')`, `MenuItem::linkToDashboard('Home', 'fa fa-home')`, `MenuItem::linkToLogout('Sign out', 'fa fa-sign-out')`, `MenuItem::linkToExitImpersonation('Stop impersonating', 'fa fa-user-secret')`, `MenuItem::section('Catalog')`, `MenuItem::subMenu('Blog', 'fa fa-book')->setSubItems([...])`. There are no other factories.  - `linkToRoute()` to a Symfony route that does not exist renders a menu that looks fine and fails with `RouteNotFoundException` when clicked. Link only to routes that exist or that you create in the same change; never guess route names.  - Every menu item accepts `setPermission()`, `setLinkTarget('_blank')`, `setLinkRel()`, `setBadge()`, `setCssClass()`, `setQueryParameter()` and `setTranslationParameters()`. The parent of a submenu links to nothing; call `keepOpen()` on it to render it expanded.  - `index()` belongs to the dashboard interface: do not add arguments to it. Inject services through the constructor.  - To open a CRUD page instead of a dashboard, redirect from `index()`: `return $this->redirectToRoute('admin_product_index');`.  - `Dashboard::new()` options: `setTitle()`, `setFaviconPath()`, `setLocales()`, `setTranslationDomain()`, `setDefaultColorScheme()`, `disableDarkMode()`, `setTheme()`. EasyAdmin never translates the contents stored in entities.   ## CRUD controller  - Declare `public static function getEntityFqcn(): string` (the base class does not) and add `/** @extends AbstractCrudController<Product> */` above the class, otherwise PHPStan reports a missing generic type.  - Overrides must keep the interface signatures: `createEntity(string $entityFqcn): ?object` (overrides may keep `: object`), `persistEntity(EntityManagerInterface $entityManager, object $entityInstance): void`, `updateEntity(...)`, `deleteEntity(...)`, and `createIndexQueryBuilder(SearchDto $searchDto, EntityDto $entityDto, FieldCollection $fields, FilterCollection $filters): QueryBuilder`.  - In `createIndexQueryBuilder()`, call `parent::createIndexQueryBuilder(...)` and use the literal root alias `entity` (`->andWhere('entity.owner = :user')`). Global Doctrine filters hide rows silently.  - Link to admin pages like to any other Symfony route, with the names listed by `php bin/console debug:router`: `$this->redirectToRoute('admin_product_detail', ['entityId' => $id])` in PHP, `path('admin_product_edit', {entityId: post.id})` in Twig. Reserve `AdminUrlGeneratorInterface` (`$this->container->get(AdminUrlGeneratorInterface::class)` inside controllers) for URLs that must be built dynamically from a controller class or from the current request: `->setController(ProductCrudController::class)->setAction(Action::DETAIL)->setEntityId($id)->generateUrl()`. `setId()` is not on the interface; use `setEntityId()`. With a controller and no action, the URL points to `index`.  - In a custom action, always receive the current entity as a typed argument (`public function publish(Product $product)`, with `{id}` in the route path; see Actions below). Only when that is impossible, inject `AdminContext $context` and read `$context->getEntity()->getInstance()`, which is nullable and untyped.  - Route names join controller and action names with underscores, so an entity whose name is a prefix of another can produce duplicate route names; the exception names both controllers. New routes appear after `cache:clear`.  - Frequent `Crud` options: `setEntityLabelInSingular()`, `setEntityLabelInPlural()`, `setPageTitle(Crud::PAGE_INDEX, 'Products')`, `setDefaultSort(['createdAt' => 'DESC'])`, `setSearchFields([...])`, `setPaginatorPageSize()`, `setFormOptions()`, `showEntityActionsInlined()`, `setDefaultRowAction()`.   ## Fields  - Use the explicit field classes from `EasyCorp\Bundle\EasyAdminBundle\Field\` with their static constructor: `TextField::new('name', 'Name')`. The generic `Field::new()` exists but guesses nothing useful in `configureFields()`. Valid options are the public methods of that class plus every method of `FieldTrait`: `setLabel()`, `setHelp()`, `setColumns()`, `setSortable()`, `setPermission()`, `setRequired()`, `setDisabled()`, `setFormType()`, `setFormTypeOption()`, `setFormTypeOptions()`, `setTemplatePath()`, `setCssClass()`, `addCssClass()`, `formatValue()`, `prepend()`, `append()`, `setHtmlAttribute()`, `setTextAlign()`. Never invent an option; check `references/api.md`.  - The page-visibility methods are exactly ten: `hideOnIndex()`, `hideOnDetail()`, `hideOnForm()`, `hideWhenCreating()`, `hideWhenUpdating()`, `onlyOnIndex()`, `onlyOnDetail()`, `onlyOnForms()`, `onlyWhenCreating()`, `onlyWhenUpdating()`. Note `hideOnForm` (singular) and `onlyOnForms` (plural). `hideOnForms()`, `onlyOnForm()`, `hideOnAll()` and `showOnIndex()` do not exist.  - `onlyOn*()` replaces the whole page list: "show the id on index and detail" is `IdField::new('id')->hideOnForm()`, not `->onlyOnIndex()`.  - `MoneyField::new('price')` has no `currency` argument: call `->setCurrency('EUR')` or `->setCurrencyPropertyPath('currency')`, and `->setStoredAsCents()` when the database stores integers. With `->useMoneyObject()`, `setStoredAsCents()` has no effect. Without a currency the page throws `You must define the currency for the "price" money field.`; with a property path, that property cannot be null on the `new` page.  - Form layout uses the static methods `FormField::addTab('Details')`, `FormField::addFieldset('Pricing')`, `FormField::addColumn(6)` and `FormField::addRow()`. `FormField::addPanel()` was removed in 5.0. The first argument of `addColumn()` is the column width, not a label.  - `ChoiceField`: `setChoices(['Draft' => 'draft'])`, `renderAsBadges(['draft' => 'warning', 'published' => 'success'])` (types: success, warning, danger, info, primary, secondary, light, dark), `renderExpanded()`, `allowMultipleChoices()`. Its `autocomplete()` takes no arguments.  - `AssociationField`: `autocomplete()` requires a CRUD controller for the related entity; `setCrudController(CategoryCrudController::class)`; `setQueryBuilder(fn (QueryBuilder $qb) => $qb->andWhere('entity.active = true'))` takes a `\Closure`; `renderAsEmbeddedForm()`; `setPreferredChoices()` does not work together with `autocomplete()`.  - `BooleanField::new('active')->renderAsSwitch()` toggles the value from the index page; that toggle is protected by the `ea-toggle` CSRF token.  - `ImageField` and `FileField`: `setBasePath('uploads/images')`, `setUploadDir('public/uploads/images')`, `setUploadedFileNamePattern('[randomhash].[extension]')`. The flags are `isDeletable()`, `isViewable()`, `isDownloadable()` (no `setDeletable()`), and the validation methods are `maxSize()` and `mimeTypes()` without a `set` prefix. `[day]`, `[month]` and `[year]` are deprecated placeholders; use `[DD]`, `[MM]`, `[YYYY]`.  - Properties edited through forms must be nullable, because Symfony Forms calls the setter with `null` before validation runs.  - Similar names differ across fields: `setNumDecimals()` (Number, Money, Percent) versus `setNumOfRows()` (Textarea, TextEditor, CodeEditor); `setStoredAsCents()` (Money), `setStoredAsFractional()` (Percent), `setStoredAsString()` (Number); `includeOnly()` and `remove()` exist only on Country, Language and Locale fields. See `references/traps.md`.   ## Actions and permissions  - A custom CRUD action is a public method with the full attribute `#[AdminRoute('/{id}/publish', name: 'publish', options: ['methods' => ['POST']])]`, linked with `Action::new('publish', 'Publish', 'fa fa-check')->linkToCrudAction('publish')` and added with `$actions->add(Crud::PAGE_INDEX, $publish)`. Without the attribute, rendering the page throws `is missing the #[AdminRoute] attribute`.  - `#[AdminRoute]` accepts only `path`, `name`, `options`, `allowedDashboards` and `deniedDashboards`. There is no `methods` argument: HTTP methods, requirements and defaults go inside `options`. Allowed methods are GET, POST, PUT, PATCH, DELETE and HEAD; the default is GET and POST.  - `{id}` (or `{entityId}`) in the path is what makes a custom action an entity action: the route carries the entity id and Symfony injects the typed entity (`public function publish(Product $product)`). Without the placeholder the route has no entity parameter and the method cannot receive the entity. Without DoctrineBundle's `controller_resolver.auto_mapping`, add `#[MapEntity]` to the argument; with `{entityId}` use the mapped form `{entityId:product.id}`. EasyAdmin throws for a missing placeholder only when the route path of the built-in `edit`, `detail` or `delete` action is customized.  - Batch actions also need `#[AdminRoute('/approve', name: 'approve', options: ['methods' => ['POST']])]` on the method, receive `BatchActionDto $batchActionDto` (`getEntityIds()`, `getEntityFqcn()`, `getCsrfToken()`), are created with `Action::new('approve')->linkToCrudAction('approve')->createAsBatchAction()` and are added with `$actions->addBatchAction($approve)`; they exist only on the index page.  - EasyAdmin adds no CSRF token to a custom action rendered with `->renderAsForm()`: the `<form method="POST">` holds only the button. Only the built-in delete action (`ea-delete`, through a shared confirmation form), batch actions and the boolean toggle (`ea-toggle`) carry tokens. Never validate a token you did not put there. To protect a custom action, add the token to the URL with `->linkToUrl(fn (Product $product) => ...)` (the closure receives the entity) or `->linkToRoute('app_publish', fn (Product $product) => ['id' => $product->getId(), 'token' => ...])`, and check it with `$this->isCsrfTokenValid('publish'.$product->getId(), $request->query->get('token'))`. Full recipe in `references/patterns.md`.  - Permissions belong to the `Actions` collection, not to `Action`: `$actions->setPermission('publish', 'ROLE_EDITOR')` and `$actions->setPermission(Action::DELETE, 'ROLE_ADMIN')`. `Action::setPermission()` does not exist. Both accept a string role or a Symfony `Expression`.  - Rendering methods are `renderAsLink()`, `renderAsButton()` and `renderAsForm()`; the `displayAs*()` names were removed in 5.0. Styling: `asPrimaryAction()`, `asSuccessAction()`, `asWarningAction()`, `asDangerAction()`, `asInfoAction()`, `asTextLink()`, and `askConfirmation()` for a confirmation modal. Groups use `ActionGroup::new()` with `asPrimaryActionGroup()` and friends.  - `reorder()` disables automatic ordering; `setCssClass()` and `addCssClass()` drop the default `.btn-*` and `.action-<name>` classes (and with them the selectors used by the test helpers); `displayIf()` on a global action receives no entity; removing or disabling `Action::DELETE` also removes `Action::BATCH_DELETE`.  - `autocomplete` and `renderFilters` are built-in action names: do not use them for custom actions.   ## Filters  - `configureFilters(Filters $filters)` adds either a property name (`->add('category')`) or a filter object (`->add(EntityFilter::new('category')->canSelectMultiple())`). By property name, EasyAdmin picks `EntityFilter` for associations, `BooleanFilter` for booleans, `DateTimeFilter` for date and time types, `NumericFilter` for numeric types, `ArrayFilter` for array types and `TextFilter` for everything else, also for nested paths (`->add('author.name')`).  - Filter options have no `set` prefix: `canSelectMultiple()`, `renderExpanded()`, `includeOnly()`, `remove()`, `preferredChoices()` and `EntityFilter::autocomplete()`; `ChoiceFilter` needs `setChoices()`.   ## Security  - `Crud::setEntityPermission('ROLE_EDITOR')` is evaluated per entity as `is_granted($permission, $entity)`: the index page hides the rows the user cannot see (and shows a notice that some results are hidden), and the detail, edit, new, delete and batch delete actions throw `InsufficientEntityPermissionException`. It does not restrict custom actions or the index page itself.  - Action permissions are checked per action: `$actions->setPermission(Action::INDEX, 'ROLE_ADMIN')` blocks the index page (and the autocomplete and filter endpoints, which check the same permission) but leaves detail, edit, new, delete and custom actions reachable by URL. To restrict a whole CRUD controller, use Symfony's `security.access_control` on its URL prefix or `#[IsGranted('ROLE_ADMIN')]` on the class.  - `MenuItem::setPermission()` only hides the menu item; the linked pages stay reachable unless their actions are protected too.  - Field-level access: `IntegerField::new('sales')->setPermission('ROLE_ADMIN')` hides the field on every page for other users.  - Every `setPermission()` accepts a `new Expression('"ROLE_EDITOR" in role_names')` besides a role string.   ## Functional tests  - Extend `EasyCorp\Bundle\EasyAdminBundle\Test\AbstractCrudTestCase` and implement the two `protected` abstract methods `getControllerFqcn()` and `getDashboardFqcn()`.  - `parent::setUp()` creates `$this->client`, `$this->entityManager` and `$this->adminUrlGenerator`: do not call `static::createClient()` again and do not redeclare those properties.  - URL helpers are `protected` and come from traits: `generateIndexUrl()`, `generateNewFormUrl()`, `generateEditFormUrl($id)`, `generateDetailUrl($id)` and `getCrudUrl('publish', $id)` for custom actions.  - Assertions: `assertIndexColumnExists('name')`, `assertIndexPageEntityCount(3)`, `assertIndexFullEntityCount(42)`, `assertIndexEntityActionExists('publish', $entityId)` (the entity id is required), `assertGlobalActionExists('new')`, `assertFormFieldExists('name')`.  - The base class does not log anyone in and loads no fixtures: log in with `$this->client->loginUser($user)` and create data through `$this->entityManager` before requesting pages.   ## Templates, design and events  - The `ea` Twig global was removed; call the `ea()` function, which returns `null` outside the admin. `ea_url()` returns the URL generator.  - Override page templates with `Crud::overrideTemplate('crud/index', 'admin/product/index.html.twig')` and field templates with `->setTemplatePath()`. The `new` and `edit` pages render form fields through Symfony form themes (`Crud::addFormTheme()`), not through field templates.  - Backend CSS lives in cascade layers (`vendor`, `ea`, `ea-overrides`), so unlayered custom CSS wins without `!important`. Override design tokens on `:root, .ea-dark-scheme`, not only on `:root`.  - Use the shipped Twig components in custom templates: `<twig:ea:Button>`, `<twig:ea:Badge>`, `<twig:ea:Alert>`, `<twig:ea:Icon>`, `<twig:ea:Modal>`, `<twig:ea:Pagination>`, `<twig:ea:Switch>`, `<twig:ea:Tabs>`, `<twig:ea:ActionMenu>`, `<twig:ea:Flag>`, `<twig:ea:Sidebar>`. Icon names are FontAwesome 6 (`fa fa-box`). Badges take `color="success"` and `variant="light|solid|outline|dot"` (default: `Crud::setBadgeVariant()`).  - Lifecycle hooks: override `persistEntity()`, `updateEntity()`, `deleteEntity()` or `createEntity()` in the controller, or subscribe to `BeforeEntityPersistedEvent`, `AfterEntityPersistedEvent`, `BeforeEntityUpdatedEvent`, `AfterEntityUpdatedEvent`, `BeforeEntityDeletedEvent`, `AfterEntityDeletedEvent`, `AfterEntityBuiltEvent`, `AfterEntitySearchEvent`, `BeforeCrudActionEvent` and `AfterCrudActionEvent` by class name. Only the `*CrudActionEvent` events can return a `Response`.   ## Legacy: what changed since EasyAdmin 4 Code and tutorials written for 4.x need these replacements. All of them are described in `vendor/easycorp/easyadmin-bundle/UPGRADE.md`. | EasyAdmin 4 | EasyAdmin 5 | |---|---| | `MenuItem::linkToCrud('Products', 'fa fa-box', Product::class)` | `MenuItem::linkTo(ProductCrudController::class, 'Products', 'fa fa-box')` | | `#[Route('/admin', name: 'admin')]` on `index()` | `#[AdminDashboard(routePath: '/admin', routeName: 'admin')]` on the class | | Public method + `linkToCrudAction('foo')` | The same, plus `#[AdminRoute]` on the method | | `#[AdminCrud]`, `#[AdminAction]` | `#[AdminRoute]` on the class or the method | | `displayAsLink()`, `displayAsButton()`, `displayAsForm()` | `renderAsLink()`, `renderAsButton()`, `renderAsForm()` | | `FormField::addPanel()` | `FormField::addFieldset()` | | URLs with `?crudAction=...&crudControllerFqcn=...` | Pretty URLs from `config/routes/easyadmin.yaml`, always | | `{{ ea.dashboardTitle }}` | `{{ ea().dashboardTitle }}` | | `$context->getReferrer()`, `$batchActionDto->getReferrerUrl()` | Removed; redirect to a generated admin URL or read the `Referer` header | | `$context->getCrudControllers()` | `$context->getAdminControllers()` | | `CacheKey::ENTITY_FQCN_TO_CRUD_FQCN` | `array_flip()` of `CacheKey::CRUD_FQCN_TO_ENTITY_FQCN` | | No PHPDoc on controllers | `/** @extends AbstractCrudController<Product> */` | `linkToCrudAction()` itself still exists: 4.x code that uses it compiles and fails at render time until the target method gets `#[AdminRoute]`.  ## If you see this error, do this | Message contains | Fix | |---|---| | `must apply the #[AdminDashboard] attribute` | Add `#[AdminDashboard(routePath: '/admin', routeName: 'admin')]` to the dashboard class. | | `missing either the "routePath" or "routeName" arguments` | Pass both arguments to `#[AdminDashboard]`. | | `is missing the #[AdminRoute] attribute` | Add `#[AdminRoute('/{id}/<action>', name: '<action>')]` to the controller method named in the message. | | `is missing the "{id}" or "{entityId}" placeholder` | Add `{id}` to the customized route path of that built-in `edit`, `detail` or `delete` action. | | `the only allowed HTTP methods are` | Use only GET, POST, PUT, PATCH, DELETE, HEAD in `options: ['methods' => [...]]`. | | `would create an admin route called "..." which already exists` | Change the `name` argument of one of the two `#[AdminRoute]` attributes. | | `cannot define both "allowedControllers" and "deniedControllers"` | Keep one of the two `#[AdminDashboard]` arguments. | | `You must define the currency for the` | Add `setCurrency('EUR')` or `setCurrencyPropertyPath()` to that `MoneyField`. | | `Batch actions can be added only to the "index" page` | Add the batch action with `addBatchAction()`, not with `add(Crud::PAGE_DETAIL, ...)`. | | `InsufficientEntityPermissionException` | Expected: the user fails `is_granted()` for that entity under `setEntityPermission()`. Log in with the right role or change the voter. | | `Class ... extends generic class ... but does not specify its types` (PHPStan) | Add `/** @extends AbstractCrudController<Entity> */`. | ## Project conventions If this repository's `AGENTS.md` or `CLAUDE.md` has a section titled `## EasyAdmin conventions`, apply it on top of these rules (base controllers, naming, permission strategy, forbidden fields, required tests).

EasyAdmin 5

This skill ships inside the easycorp/easyadmin-bundle Composer package, so it describes the API of the version installed in the project (the VERSION constant in vendor/easycorp/easyadmin-bundle/src/EasyAdminBundle.php). Trust it and the files it points to over your training data: most public code and tutorials target EasyAdmin 4, whose API differs in ways that throw exceptions on 5.x. If this copy was installed by easyadmin:ai:install, its metadata carries the version it matches; when that differs from the installed VERSION, tell the user to run php bin/console easyadmin:ai:update before you continue.

Files next to this one:

references/api.md: every public method of the config, field, filter, attribute, controller and test classes, generated from the source. If a method is not listed there, it does not exist.
references/patterns.md: copy-ready recipes for the most common tasks.
references/traps.md: method names that look right and are wrong.

Mental model

One dashboard controller (extends AbstractDashboardController) is the entry point and owns the main menu. One CRUD controller (extends AbstractCrudController) per Doctrine entity.
Everything is configured with fluent PHP inside configure*() methods. The bundle has no configuration file of its own: an easy_admin: or easyadmin: key under config/packages/ belongs to EasyAdmin 1 and 2 and does nothing on 5.x.
The four CRUD pages are Crud::PAGE_INDEX, Crud::PAGE_DETAIL, Crud::PAGE_NEW and Crud::PAGE_EDIT; configureFields(string $pageName) receives the current one.
Routes come from the #[AdminDashboard] attribute, the #[AdminRoute] attributes and the route loader declared in config/routes/easyadmin.yaml. With a dashboard route named admin, CRUD routes are named admin_<entity>_<action> (for example admin_product_index). List them with php bin/console debug:router.

Workflow

Check whether a dashboard exists: grep -rl AbstractDashboardController src/.
Scaffold with the makers and then edit the generated classes: php bin/console make:admin:dashboard and php bin/console make:admin:crud "App\Entity\Product". The CRUD maker leaves configureFields() commented out and adds no @extends PHPDoc: add both by hand.
Register every CRUD controller in the dashboard's configureMenuItems().
Before writing a method you have not seen in this skill, in references/api.md or in the source, verify it exists: grep -rn 'function <name>' vendor/easycorp/easyadmin-bundle/src/Config/ vendor/easycorp/easyadmin-bundle/src/Field/.
After adding a dashboard, a CRUD controller or an #[AdminRoute], run php bin/console cache:clear and php bin/console debug:router to confirm the routes exist before linking to them.

Dashboard and menu

The dashboard class carries #[AdminDashboard(routePath: '/admin', routeName: 'admin')] and both arguments are required. Without the attribute EasyAdmin throws a RuntimeException while generating routes and no admin route exists. Do not add a Symfony #[Route] to index(): the documentation states that no other way of configuring the dashboard route works.
The project needs config/routes/easyadmin.yaml with resource: . and type: easyadmin.routes (the value of AdminRouteLoader::ROUTE_LOADER_TYPE). Symfony Flex creates it; without Flex, create it by hand.
Link CRUD controllers with MenuItem::linkTo(ProductCrudController::class, 'Products', 'fa fa-box'): controller class first, then label, then icon. MenuItem::linkToCrud() was removed in 5.0.
The other factories put the label first: MenuItem::linkToRoute('Reports', 'fa fa-chart-bar', 'app_reports', ['year' => 2026]), MenuItem::linkToUrl('Website', 'fa fa-globe', 'https://example.com'), MenuItem::linkToDashboard('Home', 'fa fa-home'), MenuItem::linkToLogout('Sign out', 'fa fa-sign-out'), MenuItem::linkToExitImpersonation('Stop impersonating', 'fa fa-user-secret'), MenuItem::section('Catalog'), MenuItem::subMenu('Blog', 'fa fa-book')->setSubItems([...]). There are no other factories.
linkToRoute() to a Symfony route that does not exist renders a menu that looks fine and fails with RouteNotFoundException when clicked. Link only to routes that exist or that you create in the same change; never guess route names.
Every menu item accepts setPermission(), setLinkTarget('_blank'), setLinkRel(), setBadge(), setCssClass(), setQueryParameter() and setTranslationParameters(). The parent of a submenu links to nothing; call keepOpen() on it to render it expanded.
index() belongs to the dashboard interface: do not add arguments to it. Inject services through the constructor.
To open a CRUD page instead of a dashboard, redirect from index(): return $this->redirectToRoute('admin_product_index');.
Dashboard::new() options: setTitle(), setFaviconPath(), setLocales(), setTranslationDomain(), setDefaultColorScheme(), disableDarkMode(), setTheme(). EasyAdmin never translates the contents stored in entities.

CRUD controller

Declare public static function getEntityFqcn(): string (the base class does not) and add /** @extends AbstractCrudController<Product> */ above the class, otherwise PHPStan reports a missing generic type.
Overrides must keep the interface signatures: createEntity(string $entityFqcn): ?object (overrides may keep : object), persistEntity(EntityManagerInterface $entityManager, object $entityInstance): void, updateEntity(...), deleteEntity(...), and createIndexQueryBuilder(SearchDto $searchDto, EntityDto $entityDto, FieldCollection $fields, FilterCollection $filters): QueryBuilder.
In createIndexQueryBuilder(), call parent::createIndexQueryBuilder(...) and use the literal root alias entity (->andWhere('entity.owner = :user')). Global Doctrine filters hide rows silently.
Link to admin pages like to any other Symfony route, with the names listed by php bin/console debug:router: $this->redirectToRoute('admin_product_detail', ['entityId' => $id]) in PHP, path('admin_product_edit', {entityId: post.id}) in Twig. Reserve AdminUrlGeneratorInterface ($this->container->get(AdminUrlGeneratorInterface::class) inside controllers) for URLs that must be built dynamically from a controller class or from the current request: ->setController(ProductCrudController::class)->setAction(Action::DETAIL)->setEntityId($id)->generateUrl(). setId() is not on the interface; use setEntityId(). With a controller and no action, the URL points to index.
In a custom action, always receive the current entity as a typed argument (public function publish(Product $product), with {id} in the route path; see Actions below). Only when that is impossible, inject AdminContext $context and read $context->getEntity()->getInstance(), which is nullable and untyped.
Route names join controller and action names with underscores, so an entity whose name is a prefix of another can produce duplicate route names; the exception names both controllers. New routes appear after cache:clear.
Frequent Crud options: setEntityLabelInSingular(), setEntityLabelInPlural(), setPageTitle(Crud::PAGE_INDEX, 'Products'), setDefaultSort(['createdAt' => 'DESC']), setSearchFields([...]), setPaginatorPageSize(), setFormOptions(), showEntityActionsInlined(), setDefaultRowAction().

Fields

Use the explicit field classes from EasyCorp\Bundle\EasyAdminBundle\Field\ with their static constructor: TextField::new('name', 'Name'). The generic Field::new() exists but guesses nothing useful in configureFields(). Valid options are the public methods of that class plus every method of FieldTrait: setLabel(), setHelp(), setColumns(), setSortable(), setPermission(), setRequired(), setDisabled(), setFormType(), setFormTypeOption(), setFormTypeOptions(), setTemplatePath(), setCssClass(), addCssClass(), formatValue(), prepend(), append(), setHtmlAttribute(), setTextAlign(). Never invent an option; check references/api.md.
The page-visibility methods are exactly ten: hideOnIndex(), hideOnDetail(), hideOnForm(), hideWhenCreating(), hideWhenUpdating(), onlyOnIndex(), onlyOnDetail(), onlyOnForms(), onlyWhenCreating(), onlyWhenUpdating(). Note hideOnForm (singular) and onlyOnForms (plural). hideOnForms(), onlyOnForm(), hideOnAll() and showOnIndex() do not exist.
onlyOn*() replaces the whole page list: "show the id on index and detail" is IdField::new('id')->hideOnForm(), not ->onlyOnIndex().
MoneyField::new('price') has no currency argument: call ->setCurrency('EUR') or ->setCurrencyPropertyPath('currency'), and ->setStoredAsCents() when the database stores integers. With ->useMoneyObject(), setStoredAsCents() has no effect. Without a currency the page throws You must define the currency for the "price" money field.; with a property path, that property cannot be null on the new page.
Form layout uses the static methods FormField::addTab('Details'), FormField::addFieldset('Pricing'), FormField::addColumn(6) and FormField::addRow(). FormField::addPanel() was removed in 5.0. The first argument of addColumn() is the column width, not a label.
ChoiceField: setChoices(['Draft' => 'draft']), renderAsBadges(['draft' => 'warning', 'published' => 'success']) (types: success, warning, danger, info, primary, secondary, light, dark), renderExpanded(), allowMultipleChoices(). Its autocomplete() takes no arguments.
AssociationField: autocomplete() requires a CRUD controller for the related entity; setCrudController(CategoryCrudController::class); setQueryBuilder(fn (QueryBuilder $qb) => $qb->andWhere('entity.active = true')) takes a \Closure; renderAsEmbeddedForm(); setPreferredChoices() does not work together with autocomplete().
BooleanField::new('active')->renderAsSwitch() toggles the value from the index page; that toggle is protected by the ea-toggle CSRF token.
ImageField and FileField: setBasePath('uploads/images'), setUploadDir('public/uploads/images'), setUploadedFileNamePattern('[randomhash].[extension]'). The flags are isDeletable(), isViewable(), isDownloadable() (no setDeletable()), and the validation methods are maxSize() and mimeTypes() without a set prefix. [day], [month] and [year] are deprecated placeholders; use [DD], [MM], [YYYY].
Properties edited through forms must be nullable, because Symfony Forms calls the setter with null before validation runs.
Similar names differ across fields: setNumDecimals() (Number, Money, Percent) versus setNumOfRows() (Textarea, TextEditor, CodeEditor); setStoredAsCents() (Money), setStoredAsFractional() (Percent), setStoredAsString() (Number); includeOnly() and remove() exist only on Country, Language and Locale fields. See references/traps.md.

Actions and permissions

A custom CRUD action is a public method with the full attribute #[AdminRoute('/{id}/publish', name: 'publish', options: ['methods' => ['POST']])], linked with Action::new('publish', 'Publish', 'fa fa-check')->linkToCrudAction('publish') and added with $actions->add(Crud::PAGE_INDEX, $publish). Without the attribute, rendering the page throws is missing the #[AdminRoute] attribute.
#[AdminRoute] accepts only path, name, options, allowedDashboards and deniedDashboards. There is no methods argument: HTTP methods, requirements and defaults go inside options. Allowed methods are GET, POST, PUT, PATCH, DELETE and HEAD; the default is GET and POST.
{id} (or {entityId}) in the path is what makes a custom action an entity action: the route carries the entity id and Symfony injects the typed entity (public function publish(Product $product)). Without the placeholder the route has no entity parameter and the method cannot receive the entity. Without DoctrineBundle's controller_resolver.auto_mapping, add #[MapEntity] to the argument; with {entityId} use the mapped form {entityId:product.id}. EasyAdmin throws for a missing placeholder only when the route path of the built-in edit, detail or delete action is customized.
Batch actions also need #[AdminRoute('/approve', name: 'approve', options: ['methods' => ['POST']])] on the method, receive BatchActionDto $batchActionDto (getEntityIds(), getEntityFqcn(), getCsrfToken()), are created with Action::new('approve')->linkToCrudAction('approve')->createAsBatchAction() and are added with $actions->addBatchAction($approve); they exist only on the index page.
EasyAdmin adds no CSRF token to a custom action rendered with ->renderAsForm(): the <form method="POST"> holds only the button. Only the built-in delete action (ea-delete, through a shared confirmation form), batch actions and the boolean toggle (ea-toggle) carry tokens. Never validate a token you did not put there. To protect a custom action, add the token to the URL with ->linkToUrl(fn (Product $product) => ...) (the closure receives the entity) or ->linkToRoute('app_publish', fn (Product $product) => ['id' => $product->getId(), 'token' => ...]), and check it with $this->isCsrfTokenValid('publish'.$product->getId(), $request->query->get('token')). Full recipe in references/patterns.md.
Permissions belong to the Actions collection, not to Action: $actions->setPermission('publish', 'ROLE_EDITOR') and $actions->setPermission(Action::DELETE, 'ROLE_ADMIN'). Action::setPermission() does not exist. Both accept a string role or a Symfony Expression.
Rendering methods are renderAsLink(), renderAsButton() and renderAsForm(); the displayAs*() names were removed in 5.0. Styling: asPrimaryAction(), asSuccessAction(), asWarningAction(), asDangerAction(), asInfoAction(), asTextLink(), and askConfirmation() for a confirmation modal. Groups use ActionGroup::new() with asPrimaryActionGroup() and friends.
reorder() disables automatic ordering; setCssClass() and addCssClass() drop the default .btn-* and .action-<name> classes (and with them the selectors used by the test helpers); displayIf() on a global action receives no entity; removing or disabling Action::DELETE also removes Action::BATCH_DELETE.
autocomplete and renderFilters are built-in action names: do not use them for custom actions.

Filters

configureFilters(Filters $filters) adds either a property name (->add('category')) or a filter object (->add(EntityFilter::new('category')->canSelectMultiple())). By property name, EasyAdmin picks EntityFilter for associations, BooleanFilter for booleans, DateTimeFilter for date and time types, NumericFilter for numeric types, ArrayFilter for array types and TextFilter for everything else, also for nested paths (->add('author.name')).
Filter options have no set prefix: canSelectMultiple(), renderExpanded(), includeOnly(), remove(), preferredChoices() and EntityFilter::autocomplete(); ChoiceFilter needs setChoices().

Security

Crud::setEntityPermission('ROLE_EDITOR') is evaluated per entity as is_granted($permission, $entity): the index page hides the rows the user cannot see (and shows a notice that some results are hidden), and the detail, edit, new, delete and batch delete actions throw InsufficientEntityPermissionException. It does not restrict custom actions or the index page itself.
Action permissions are checked per action: $actions->setPermission(Action::INDEX, 'ROLE_ADMIN') blocks the index page (and the autocomplete and filter endpoints, which check the same permission) but leaves detail, edit, new, delete and custom actions reachable by URL. To restrict a whole CRUD controller, use Symfony's security.access_control on its URL prefix or #[IsGranted('ROLE_ADMIN')] on the class.
MenuItem::setPermission() only hides the menu item; the linked pages stay reachable unless their actions are protected too.
Field-level access: IntegerField::new('sales')->setPermission('ROLE_ADMIN') hides the field on every page for other users.
Every setPermission() accepts a new Expression('"ROLE_EDITOR" in role_names') besides a role string.

Functional tests

Extend EasyCorp\Bundle\EasyAdminBundle\Test\AbstractCrudTestCase and implement the two protected abstract methods getControllerFqcn() and getDashboardFqcn().
parent::setUp() creates $this->client, $this->entityManager and $this->adminUrlGenerator: do not call static::createClient() again and do not redeclare those properties.
URL helpers are protected and come from traits: generateIndexUrl(), generateNewFormUrl(), generateEditFormUrl($id), generateDetailUrl($id) and getCrudUrl('publish', $id) for custom actions.
Assertions: assertIndexColumnExists('name'), assertIndexPageEntityCount(3), assertIndexFullEntityCount(42), assertIndexEntityActionExists('publish', $entityId) (the entity id is required), assertGlobalActionExists('new'), assertFormFieldExists('name').
The base class does not log anyone in and loads no fixtures: log in with $this->client->loginUser($user) and create data through $this->entityManager before requesting pages.

Templates, design and events

The ea Twig global was removed; call the ea() function, which returns null outside the admin. ea_url() returns the URL generator.
Override page templates with Crud::overrideTemplate('crud/index', 'admin/product/index.html.twig') and field templates with ->setTemplatePath(). The new and edit pages render form fields through Symfony form themes (Crud::addFormTheme()), not through field templates.
Backend CSS lives in cascade layers (vendor, ea, ea-overrides), so unlayered custom CSS wins without !important. Override design tokens on :root, .ea-dark-scheme, not only on :root.
Use the shipped Twig components in custom templates: <twig:ea:Button>, <twig:ea:Badge>, <twig:ea:Alert>, <twig:ea:Icon>, <twig:ea:Modal>, <twig:ea:Pagination>, <twig:ea:Switch>, <twig:ea:Tabs>, <twig:ea:ActionMenu>, <twig:ea:Flag>, <twig:ea:Sidebar>. Icon names are FontAwesome 6 (fa fa-box). Badges take color="success" and variant="light|solid|outline|dot" (default: Crud::setBadgeVariant()).
Lifecycle hooks: override persistEntity(), updateEntity(), deleteEntity() or createEntity() in the controller, or subscribe to BeforeEntityPersistedEvent, AfterEntityPersistedEvent, BeforeEntityUpdatedEvent, AfterEntityUpdatedEvent, BeforeEntityDeletedEvent, AfterEntityDeletedEvent, AfterEntityBuiltEvent, AfterEntitySearchEvent, BeforeCrudActionEvent and AfterCrudActionEvent by class name. Only the *CrudActionEvent events can return a Response.

Legacy: what changed since EasyAdmin 4

Code and tutorials written for 4.x need these replacements. All of them are described in vendor/easycorp/easyadmin-bundle/UPGRADE.md.

EasyAdmin 4	EasyAdmin 5
`MenuItem::linkToCrud('Products', 'fa fa-box', Product::class)`	`MenuItem::linkTo(ProductCrudController::class, 'Products', 'fa fa-box')`
`#[Route('/admin', name: 'admin')]` on `index()`	`#[AdminDashboard(routePath: '/admin', routeName: 'admin')]` on the class
Public method + `linkToCrudAction('foo')`	The same, plus `#[AdminRoute]` on the method
`#[AdminCrud]`, `#[AdminAction]`	`#[AdminRoute]` on the class or the method
`displayAsLink()`, `displayAsButton()`, `displayAsForm()`	`renderAsLink()`, `renderAsButton()`, `renderAsForm()`
`FormField::addPanel()`	`FormField::addFieldset()`
URLs with `?crudAction=...&crudControllerFqcn=...`	Pretty URLs from `config/routes/easyadmin.yaml`, always
`{{ ea.dashboardTitle }}`	`{{ ea().dashboardTitle }}`
`$context->getReferrer()`, `$batchActionDto->getReferrerUrl()`	Removed; redirect to a generated admin URL or read the `Referer` header
`$context->getCrudControllers()`	`$context->getAdminControllers()`
`CacheKey::ENTITY_FQCN_TO_CRUD_FQCN`	`array_flip()` of `CacheKey::CRUD_FQCN_TO_ENTITY_FQCN`
No PHPDoc on controllers	`/** @extends AbstractCrudController<Product> */`

linkToCrudAction() itself still exists: 4.x code that uses it compiles and fails at render time until the target method gets #[AdminRoute].

If you see this error, do this

Message contains	Fix
`must apply the #[AdminDashboard] attribute`	Add `#[AdminDashboard(routePath: '/admin', routeName: 'admin')]` to the dashboard class.
`missing either the "routePath" or "routeName" arguments`	Pass both arguments to `#[AdminDashboard]`.
`is missing the #[AdminRoute] attribute`	Add `#[AdminRoute('/{id}/<action>', name: '<action>')]` to the controller method named in the message.
`is missing the "{id}" or "{entityId}" placeholder`	Add `{id}` to the customized route path of that built-in `edit`, `detail` or `delete` action.
`the only allowed HTTP methods are`	Use only GET, POST, PUT, PATCH, DELETE, HEAD in `options: ['methods' => [...]]`.
`would create an admin route called "..." which already exists`	Change the `name` argument of one of the two `#[AdminRoute]` attributes.
`cannot define both "allowedControllers" and "deniedControllers"`	Keep one of the two `#[AdminDashboard]` arguments.
`You must define the currency for the`	Add `setCurrency('EUR')` or `setCurrencyPropertyPath()` to that `MoneyField`.
`Batch actions can be added only to the "index" page`	Add the batch action with `addBatchAction()`, not with `add(Crud::PAGE_DETAIL, ...)`.
`InsufficientEntityPermissionException`	Expected: the user fails `is_granted()` for that entity under `setEntityPermission()`. Log in with the right role or change the voter.
`Class ... extends generic class ... but does not specify its types` (PHPStan)	Add `/** @extends AbstractCrudController<Entity> */`.
