laravel-repository

切换中文 | Usage of Repository

Introduction

laravel-repository provides the basic repository class for laravel model The package was made to provide more More external methods, and more friendly editor prompts; layering the code, repository is responsible for external business logic processing, model is only responsible for the definition of the fields, attributes, query conditions, and return values of the data table. It does not participate in specific logical operations, and does not serve the control layer.

Relative to the direct use of model advantages:

• Solve the problem that model does not automatically handle extra fields when adding or modifying
• Optimize chained calls for model queries, query directly using arrays
• Automatically process corresponding associated data queries through query conditions and query fields
• Provides a more friendly editor prompt

Install

Installation requirements

• PHP >= 7.0.0
• Laravel >= 5.5.0

1.1 Install package

composer require littlebug/laravel-repository:2.0.*

or add this to require section in your composer.json file:

"littlebug/laravel-repository": "2.0.*"

then run composer update

1.2 Use the command to generate model and repository

Suppose you have users in your database, or you replace users with the table names in your database.

php artisan core:model --table=users --name=User

The command will be at:

• Generate User file under app/Models/ file
• Generate UserRepository file under app/Repositories/ file

1.3 Using repository in the controller

<?php

use Illuminate\Routing\Controller;
use Littlebug\Repository\Tests\Stubs\UserRepository;

class UsersController extends Controller 
{
    /**
     * @var UserRepository
     */
    private $userRepository;
    
    public function __construct(UserRepository $userRepository)
    {
        $this->userRepository = $userRepository;
    }
    
    public function index()
    {
        // Paging queries, returning paging objects
        $paginate = $this->userRepository->paginate([
            'name:like' => 'test', 
            'status'    => [1, 2], // Automatically converts to an in query,

            // Add complex queries and generate SQL: ("users"."status" = ? or "users"."age" >= ? or ("users"."status" = ? and "users"."age" != ?))
            // More instructions: https://wanchaochao.github.io/laravel-repository/?page=repository#5.3-%E9%A2%84%E5%AE%9A%E4%B9%89%E5%AD%97%E6%AE%B5%E6%9F%A5%E8%AF%A2
            'or' => [
                'status'  => 1,
                'age:gte' => 26,
                'and'     => [
                    'status'  => 1,
                    'age:neq' => 24,
                ],
            ],
        ], [
            'user_id',
            'username',
            
            // Statistical associated data; withCount  
            'posts_count',      

            // Query the field information for the association table if the model defines the association relationship
            'ext' => [
                'user_id',
                'ext_avatar', 
            ],
        ]);
        
        return view('users.index', compact('paginate'));
    }
    
    public function create()
    {
        // Add data and return an array
        $user = $this->userRepository->create(request()->all());
        dump($user);
    }
    
    public function update()
    {
        // Modify the data and return the number of modified rows
        $row = $this->userRepository->update(request()->input('id'), request()->all());
        dump($row);
    }
    
    public function delete()
    {
        // Deletes data and returns the number of rows deleted
        $row = $this->userRepository->delete(request()->input('id'));
        dump($row);
    }
}

In addition to the injection method invocation described above, you can also use static method invocation; As follows:

use Littlebug\Repository\Tests\Stubs\UserRepository;

$paginate = UserRepository::instance()->paginate(['status' => 1]);

// Query a piece of data and return an array
$user = UserRepository::instance()->find(['status' => 1, 'id:gt' => 2]);

1.4 Other common methods

Retrieve the data

Statistical query

Create or modify data

More code generation commands

Commands support specifying database connections such as --table=dev.users

1. core:model generates model class files and repository class files by querying database table information.

   php artisan core:model --table=users --name=User
   

2. core:repository generates the repository class file

   php artisan core:repository --model=User --name=UserRepository
   

3. core:request generates request verification class file by querying database table information

   php artisan core:request --table=users --path=Users
