Eloquent Versioned Laravel Package

Getting Started

• Install the package with Composer, then complete any Laravel 5.2-specific setup: register the service provider manually if package auto-discovery is not available, publish config/migrations, and run migrations.
• Add the package’s versioning trait/interface to the Eloquent model you want to track. Check the README for the exact trait name and expected schema columns before wiring it into production models.
• First day-to-day use case: render a model’s version history. From a version record, use getPreviousModel() and getNextModel() to build previous/next navigation on a version detail page.
• Start by testing the flow on one low-risk model: create, update, load history, and traverse between adjacent versions. Confirm boundary behavior before building UI around it.

Implementation Patterns

• Version creation: keep normal Eloquent create/update flows, but wrap writes that depend on generated model IDs in a database transaction. The 0.1.2 model_id fix reduces race risk, but transactions and sensible DB constraints still belong in application code.
• Version browsing: load a model’s versions ordered by a stable key such as created_at plus id, then use getPreviousModel() / getNextModel() for detail-page navigation. These methods fit naturally into “older/newer version” links and audit/history screens.
• Controller pattern: authorize access to both the source model and the version record, then pass current/previous/next versions to the view. Do not rely on route model binding alone if versions may reference soft-deleted or restricted records.
• UI pattern: show version metadata, previous/next buttons, and a link back to the live model. Disable buttons when the traversal methods return null.
• Query pattern: scope history queries by the configured model type/id columns and paginate large histories. Eager-load relationships needed on version detail pages to avoid N+1 queries.
• Laravel 5.2 pattern: treat this release as the compatibility baseline. Test middleware, route model binding, and service-provider registration on 5.2 specifically; do not assume the same setup works on modern Laravel without checking constraints.
• Integration tip: publish and review the package config/migrations rather than editing vendor files. If the package supports configurable table/model columns, set those before running migrations in existing apps.

Gotchas and Tips

• This is an early 0.1.x package. Pin the version in composer.json and review the README/changelog before upgrading; APIs around version traversal and model association may still evolve.
• getPreviousModel() and getNextModel() will likely return null at the boundaries of a version list. Handle that explicitly in controllers and views.
• The improved model_id determination helps with race conditions, but concurrent writes can still create ordering ambiguity. Use transactions, stable ordering, and database constraints where correctness matters.
• Do not order solely by created_at; timestamps can collide. Use a deterministic secondary sort such as id.
• Laravel 5.2 compatibility means older framework conventions may apply: manual provider registration, older package-discovery behavior, and different testing/setup expectations. Verify before mixing this package into a newer Laravel codebase.
• Version records can expose historical values that are no longer public. Add authorization and field filtering at the application layer.
• Test both traversal directions and edge cases: first version, last version, deleted model, and multiple rapid updates. Feature tests should assert that previous/next links never point to a version from another model.
• Treat published config and migrations as extension points. If the package defaults do not fit existing table naming or tenancy rules, adjust them early rather than patching vendor code.
