Resource Route is a method in Laravel to quickly generate standard RESTful routes through Route::resource. 1. It can automatically generate 7 common CRUD operation routes, corresponding to index, create, store, show, edit, update, destroy methods in the controller; 2. The basic usage is to bind URI name and controller class, such as Route::resource('posts', PostController::class); 3. You can use the Artisan command php artisan make:controller to create a controller with resource method template; 4. Support only partial routes or exclude certain routes, such as only() or except() methods; 5. You can customize URI names, add middleware and naming prefixes; 6. Notes include method name matching, parameter consistency, and API usage differences, API Route::apiResource() is recommended for scenes.

In Laravel, Route::resource is a very practical method to quickly define a set of standard RESTful routes for a certain controller. It can automatically generate common CRUD operation routes (such as index, create, store, show, edit, update, destroy) for you, saving you the trouble of manually writing routes one by one.

What is Resource Route?

When you have a resource-based controller, such as PostController , and you need to provide the functions of adding, deleting, modifying and checking articles, you can use Route::resource to generate all standard routes in one click.

 Route::resource('posts', PostController::class);

The above line of code will automatically generate the following 7 routes:

• GET /posts → index
• GET /posts/create → create
• POST /posts → store
• GET /posts/{post} → show
• GET /posts/{post}/edit → edit
• PUT/PATCH /posts/{post} → update
• DELETE /posts/{post} → destroy

These routes correspond to the method name in the controller by default, so it is best to organize the methods in your controller according to this naming.

How to use Resource Route?

Basic usage

You just need to add the following code in routes/web.php or api.php :

 use App\Http\Controllers\PostController;

Route::resource('posts', PostController::class);

Laravel will automatically bind all RESTful routes based on the URI name (such as posts ) and controller class you passed in.

Controller Generation Suggestions

You can use the Artisan command to create a controller with the resource method:

 php artisan make:controller PostController --resource

The controller generated in this way already contains all the necessary method templates.

Optional parameters and advanced usage

Sometimes you don't need all 7 routes, or want to customize some behaviors, you can use the following options:

Generate only partial routes

 Route::resource('posts', PostController::class)->only([
    'index', 'show', 'create', 'store'
]);

Or exclude certain routes:

 Route::resource('posts', PostController::class)->except(['destroy']);

Custom URI name

If you want the access path to be /posts , you can modify:

 Route::resource('blog', PostController::class);

At this time, the access path becomes /blog , but the controller method remains unchanged.

Replace controller name or middleware

You can add middleware, namespace, etc. to resource route:

 Route::resource('posts', PostController::class)
    ->middleware('auth')
    ->names('admin.posts');

This way all route names will be prefixed, such as admin.posts.index .

Notes and FAQs

• The controller method name must match : make sure that your controller has index , create , store , show , edit , update , destroy methods.
• Parameter naming must be consistent : By default, Laravel uses {模型名} as parameter name, such as Post $post , otherwise an error may be reported.
• The difference between Resource Route and API : If you are doing API development, you usually don’t need the two routes that return pages, create and edit . At this time, you can use Route::apiResource() to generate only 5 routes suitable for the API.

Basically that's it. Resource Route is a very considerate feature provided by Laravel. Although it is simple, understanding its rules and applicable scenarios can help you save a lot of time.
