Resource routes in Laravel - Mini Project: Build & Apply

Creating Resource Routes in Laravel

📖 Scenario: You are building a simple blog application where users can manage posts. You want to set up routes that handle all the common actions like listing posts, showing a single post, creating, updating, and deleting posts.

🎯 Goal: Set up a resource route in Laravel that automatically creates all the standard routes for managing posts.

📋 What You'll Learn

Create a route group for posts using Laravel's resource routing

Use the exact resource name posts

Use the controller named PostController

Ensure the resource route is registered in the routes/web.php file

💡 Why This Matters

🌍 Real World

Resource routes in Laravel help quickly set up all the common routes needed for CRUD operations on resources like posts, users, or products.

💼 Career

Understanding resource routes is essential for Laravel developers to build RESTful web applications efficiently and follow best practices.

1

Create the posts resource route

In the routes/web.php file, add a resource route for posts using the PostController. Write the exact line: Route::resource('posts', PostController::class);

Laravel

<?php

use Illuminate\Support\Facades\Route;

// Add the resource route for posts here

Hint

Use Laravel's Route::resource method with the exact resource name 'posts' and controller PostController::class.

2

Add a route name prefix

Modify the resource route to add a name prefix blog. so that all route names start with blog.. Write the exact code: Route::resource('posts', PostController::class)->names('blog');

Laravel

<?php

use Illuminate\Support\Facades\Route;

// Add the name prefix 'blog.' to the resource route

Hint

Use the ->names('blog') method chained to the resource route to add the prefix.

3

Limit resource routes to only index and show

Change the resource route to only include the index and show methods. Write the exact code: Route::resource('posts', PostController::class)->only(['index', 'show']);

Laravel

<?php

use Illuminate\Support\Facades\Route;

// Limit the resource route to only 'index' and 'show' methods

Hint

Use the ->only(['index', 'show']) method chained to the resource route to limit the routes.

4

Exclude the create and edit routes

Modify the resource route to exclude the create and edit methods. Write the exact code: Route::resource('posts', PostController::class)->except(['create', 'edit']);

Laravel

<?php

use Illuminate\Support\Facades\Route;

// Exclude 'create' and 'edit' methods from the resource route

Hint

Use the ->except(['create', 'edit']) method chained to the resource route to exclude those routes.

Practice

1. What does the Route::resource('photos', PhotoController::class) method do in Laravel?

easy

A. Creates multiple routes for common CRUD actions automatically.

B. Creates a single route for the index method only.

C. Creates routes only for the create and edit methods.

D. Deletes all existing routes related to photos.

Solution

1. Step 1: Understand the purpose of Route::resource

   This method generates routes for all standard CRUD actions (index, create, store, show, edit, update, destroy) automatically.

2. Step 2: Recognize the effect on routes

   It saves time by creating multiple routes with correct HTTP verbs and URLs for the resource controller.

3. Final Answer:

   Creates multiple routes for common CRUD actions automatically. -> Option A

4. Quick Check:

   Resource routes = multiple CRUD routes [OK]

Hint: Resource routes generate all CRUD URLs in one line [OK]

Common Mistakes:

• Thinking it creates only one route
• Confusing resource with single route methods
• Assuming it deletes routes

2. Which of the following is the correct syntax to create resource routes for a controller named PostController?

easy

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

B. Route::resource('posts', 'PostController');

C. Route::resource('posts', PostController);

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

Solution

1. Step 1: Identify correct controller reference syntax

   In Laravel, the controller class should be passed using the ::class constant without quotes.

2. Step 2: Check each option

   Route::resource('posts', PostController::class); correctly uses PostController::class without quotes, which is the modern and recommended syntax.

3. Final Answer:

   Route::resource('posts', PostController::class); -> Option D

4. Quick Check:

   Use ControllerName::class without quotes [OK]

Hint: Use ControllerName::class without quotes for resource routes [OK]

Common Mistakes:

• Passing controller name as a string with quotes
• Omitting ::class
• Using quotes around ::class

3. Given the route definition Route::resource('books', BookController::class)->only(['index', 'show']);, which URLs will be available?

medium

A. /books/create (GET) and /books/{book}/edit (GET)

B. /books (GET) and /books/{book} (GET)

C. /books (POST) and /books/{book} (DELETE)

D. /books/{book} (PUT) and /books/{book} (PATCH)

Solution

1. Step 1: Understand the only() method

   The only() method limits resource routes to specified actions. Here, only 'index' and 'show' routes are created.

2. Step 2: Identify routes for index and show

   Index route is GET /books, show route is GET /books/{book}.

3. Final Answer:

   /books (GET) and /books/{book} (GET) -> Option B

4. Quick Check:

   only(['index','show']) = GET /books and GET /books/{id} [OK]

Hint: only(['index','show']) creates just list and detail GET routes [OK]

Common Mistakes:

• Confusing HTTP verbs for actions
• Assuming create/edit routes are included
• Mixing POST or DELETE with index/show

4. What is wrong with this route definition?

Route::resource('users', UserController::class)->except('store');

medium

A. The except() method requires an array, not a string.

B. UserController::class should be a string.

C. Resource routes cannot use except() method.

D. The route name 'users' is invalid.

Solution

1. Step 1: Check except() method usage

   The except() method expects an array of action names to exclude, not a single string.

2. Step 2: Identify correct syntax

   It should be except(['store']) with square brackets to pass an array.

3. Final Answer:

   The except() method requires an array, not a string. -> Option A

4. Quick Check:

   Use except(['action']) with array brackets [OK]

Hint: Pass array to except(), not a single string [OK]

Common Mistakes:

• Passing string instead of array to except()
• Using quotes incorrectly around controller class
• Thinking except() is not allowed

5. You want to create resource routes for ArticleController but only allow routes for creating, storing, and editing articles. Which is the correct route definition?

hard

A. Route::resource('articles', ArticleController::class)->only(['create', 'store', 'edit']);

B. Route::resource('articles', ArticleController::class)->only(['create', 'edit']);

C. Route::resource('articles', ArticleController::class)->except(['index', 'show', 'update', 'destroy']);

D. Route::resource('articles', ArticleController::class)->except(['store']);

Solution

1. Step 1: Identify required actions

   We want routes for create, store, and edit only.

2. Step 2: Use except() to exclude unwanted actions

   Excluding index, show, update, and destroy leaves only create, store, and edit routes.

3. Step 3: Confirm only() option

   Route::resource('articles', ArticleController::class)->only(['create', 'store', 'edit']); correctly includes the store route, but using except() as in Route::resource('articles', ArticleController::class)->except(['index', 'show', 'update', 'destroy']); is also correct and often preferred for excluding unwanted routes.

4. Final Answer:

   Route::resource('articles', ArticleController::class)->except(['index', 'show', 'update', 'destroy']); -> Option C

5. Quick Check:

   except(['index','show','update','destroy']) = create, store, edit routes [OK]

Hint: Use except() to exclude unwanted routes for precise control [OK]

Common Mistakes:

• Using only() but missing store route
• Excluding wrong actions
• Confusing create and store routes
