How to nest resource routes in Laravel?

Jul 18, 2025 am 01:58 AM

Nested routes are used in Laravel to express the affiliation between resources, such as comments under the article; use Route::resource('posts.comments', CommentController::class) to create nested routes to generate URLs similar to /posts/{post}/comments/{comment}; controller methods need to receive parent parameters such as public function show(Post $post, Comment $comment); when generating links, the parameter order should be preceded by parent such as route('posts.comments.show', [$post, $comment]); common errors include parameter order errors, model not introduced, and naming spelling issues.

How to nest resource routes in Laravel?

When nesting routing resources in Laravel, the key is to understand how to organize the routing structure of the parent-child relationship through Route::resource() method. Laravel provides a very convenient way to define nested resource routing, but attention should be paid to the correspondence between naming and controller methods.

How to nest resource routes in Laravel?

Why do you need nested routes?

When you have business logic like "comments placed by articles" or "orders placed by users", using nested routing can express this affiliation more clearly. The URL structure is usually like this:

 /posts/{post}/comments/{comment}

This means that comment belongs to a certain post.

How to set up nested routing correctly

In the routes/web.php file, you can write this:

 Route::resource('posts.comments', CommentController::class);

The above line of code will automatically generate a route with nested parameters, such as the URL to access comment details is:

How to nest resource routes in Laravel?
 GET /posts/{post}/comments/{comment}

Notice:

  • The controller does not need to handle nested logic extra, just make sure that the parent ID is received in the method.
  • Nesting levels can be multi-layered, such as posts.comments.likes .

How to write a method in the controller?

Taking CommentController as an example, you only need to add the $post parameter to the method:

 public function show(Post $post, Comment $comment)
{
    // You can use $post and $comment directly here
    return view('comments.show', compact('post', 'comment'));
}

Laravel will automatically parse model instances based on the route, provided that your model name is consistent with the routing parameters (such as {post} corresponding to Post::class ).


When you want to generate nested route links in a Blade template, pay attention to the order of passing parameters:

 <a href="{{ route(&#39;posts.comments.show&#39;, [$post, $comment]) }}">
    View Comments</a>

If you are creating a new comment, you can only pass it to the parent:

 <a href="{{ route(&#39;posts.comments.create&#39;, $post) }}">
    Add a comment</a>

Avoid common mistakes

  • Mistake of parameter order : The first parameter in the nested route is always the parent resource.
  • The controller has not introduced a parent model : don't forget to add parent model parameters to the method signature.
  • Resource naming errors : For example, &#39;posts.comment&#39; and &#39;posts.comments&#39; are different.

If you use the Artisan command to view the route list:

 php artisan route:list

You will see that all generated nested paths have two parameters.


Basically that's it. Although nested resource routing seems a bit complicated, as long as you master the writing method and calling method, it is actually not difficult, it is just easy to ignore the parameter order and naming consistency.

Understanding Dependency Injection in Laravel? Understanding Dependency Injection in Laravel? Jul 05, 2025 am 02:01 AM

Dependency injection automatically handles class dependencies through service containers in Laravel without manual new objects. Its core is constructor injection and method injection, such as automatically passing in the Request instance in the controller. Laravel parses dependencies through type prompts and recursively creates the required objects. The binding interface and implementation can be used by the service provider to use the bind method, or singleton to bind a singleton. When using it, you need to ensure type prompts, avoid constructor complications, use context bindings with caution, and understand automatic parsing rules. Mastering these can improve code flexibility and maintenance.

Strategies for optimizing Laravel application performance Strategies for optimizing Laravel application performance Jul 09, 2025 am 03:00 AM

Laravel performance optimization can improve application efficiency through four core directions. 1. Use the cache mechanism to reduce duplicate queries, store infrequently changing data through Cache::remember() and other methods to reduce database access frequency; 2. Optimize database from the model to query statements, avoid N 1 queries, specifying field queries, adding indexes, paging processing and reading and writing separation, and reduce bottlenecks; 3. Use time-consuming operations such as email sending and file exporting to queue asynchronous processing, use Supervisor to manage workers and set up retry mechanisms; 4. Use middleware and service providers reasonably to avoid complex logic and unnecessary initialization code, and delay loading of services to improve startup efficiency.

Managing database state for testing in Laravel Managing database state for testing in Laravel Jul 13, 2025 am 03:08 AM

Methods to manage database state in Laravel tests include using RefreshDatabase, selective seeding of data, careful use of transactions, and manual cleaning if necessary. 1. Use RefreshDatabasetrait to automatically migrate the database structure to ensure that each test is based on a clean database; 2. Use specific seeds to fill the necessary data and generate dynamic data in combination with the model factory; 3. Use DatabaseTransactionstrait to roll back the test changes, but pay attention to its limitations; 4. Manually truncate the table or reseed the database when it cannot be automatically cleaned. These methods are flexibly selected according to the type of test and environment to ensure the reliability and efficiency of the test.

Choosing between Laravel Sanctum and Passport for API authentication Choosing between Laravel Sanctum and Passport for API authentication Jul 14, 2025 am 02:35 AM

LaravelSanctum is suitable for simple, lightweight API certifications such as SPA or mobile applications, while Passport is suitable for scenarios where full OAuth2 functionality is required. 1. Sanctum provides token-based authentication, suitable for first-party clients; 2. Passport supports complex processes such as authorization codes and client credentials, suitable for third-party developers to access; 3. Sanctum installation and configuration are simpler and maintenance costs are low; 4. Passport functions are comprehensive but configuration is complex, suitable for platforms that require fine permission control. When selecting, you should determine whether the OAuth2 feature is required based on the project requirements.

Implementing Database Transactions in Laravel? Implementing Database Transactions in Laravel? Jul 08, 2025 am 01:02 AM

Laravel simplifies database transaction processing with built-in support. 1. Use the DB::transaction() method to automatically commit or rollback operations to ensure data integrity; 2. Support nested transactions and implement them through savepoints, but it is usually recommended to use a single transaction wrapper to avoid complexity; 3. Provide manual control methods such as beginTransaction(), commit() and rollBack(), suitable for scenarios that require more flexible processing; 4. Best practices include keeping transactions short, only using them when necessary, testing failures, and recording rollback information. Rationally choosing transaction management methods can help improve application reliability and performance.

Handling HTTP Requests and Responses in Laravel. Handling HTTP Requests and Responses in Laravel. Jul 16, 2025 am 03:21 AM

The core of handling HTTP requests and responses in Laravel is to master the acquisition of request data, response return and file upload. 1. When receiving request data, you can inject the Request instance through type prompts and use input() or magic methods to obtain fields, and combine validate() or form request classes for verification; 2. Return response supports strings, views, JSON, responses with status codes and headers and redirect operations; 3. When processing file uploads, you need to use the file() method and store() to store files. Before uploading, you should verify the file type and size, and the storage path can be saved to the database.
