Optimizing Route Permissions with Laravel's Enhanced Enum Support

Laravel optimized routing permissions: Enhanced enumeration support

If you have been using enums and Laravel's Route::can() method, you may be familiar with attaching ->value to permission checks. Laravel now simplifies this process with built-in enumeration support for routing permissions. Let's explore this enhancement that makes your code more concise and elegant.

Previous and back comparison

The following is how grammar evolves:

// 旧方法
Route::get('/posts', function () {...})->can(PostPermissions::CREATE_POST->value);
// 新方法
Route::get('/posts', function () {...})->can(PostPermissions::CREATE_POST);

No more need ->value—It's that simple!

Practical Application

Let's implement this in a content management system with various permission levels:

<?php namespace App\Enums;

use App\Enums\BackedEnum;

class ContentPermissions extends BackedEnum
{
    case VIEW_CONTENT = 'view_content';
    case PUBLISH_POST = 'publish_post';
    case MODERATE_COMMENTS = 'moderate_comments';
}

Route::prefix('content')->group(function () {
    Route::get('/dashboard', [ContentController::class, 'index'])
        ->can(ContentPermissions::VIEW_CONTENT);

    Route::post('/posts', [PostController::class, 'store'])
        ->can(ContentPermissions::PUBLISH_POST);

    Route::put('/comments/{comment}', [CommentController::class, 'update'])
        ->can(ContentPermissions::MODERATE_COMMENTS);
});

In this example, we:

• Define our permissions using enumerations that support values
• Group the relevant routes under a public prefix
• Use the permission check directly using enumeration situation

This approach enhances the readability of the code and keeps type-safe with enumerations of PHP supported values. The result is a more easily maintained and expressed routing definition that better represents the permission structure of the application.
