Practice - 5 Tasks

1fill in blank

easy

💡 Hint

Common Mistakes

Using 'get' or 'post' instead of 'resource' will only create a single route.

Forgetting to specify the controller class.

The resource method registers all standard resource routes for a controller in Laravel.

2fill in blank

medium

Complete the code to limit resource routes to only 'index' and 'show' methods.

Laravel

Route::resource('products', ProductController::class)->[1](['index', 'show']);

Drag options to blanks, or click blank then click option'

Aexcept

Blimit

Conly

Dfilter

Attempts:

💡 Hint

Common Mistakes

Using 'except' will exclude the listed methods instead of including them.

Using non-existent methods like 'limit' or 'filter' causes errors.

The only method restricts the resource routes to specified actions.

3fill in blank

hard

Fix the error in the code to register resource routes with a custom parameter name.

Laravel

Route::resource('users', UserController::class)->parameters(['users' => '[1]']);

Drag options to blanks, or click blank then click option'

Auser

Buser_id

Cid

Dusers_id

Attempts:

💡 Hint

Common Mistakes

Using plural or underscored names causes route model binding to fail.

Using 'id' alone does not match the resource parameter naming convention.

The parameter name should be singular and match the route parameter used in the controller methods.

4fill in blank

hard

Fill both blanks to register resource routes with a custom route name prefix and only 'create' and 'store' methods.

Laravel

Route::resource('orders', OrderController::class)->[1](['create', 'store'])->names(['create' => '[2]']);

Drag options to blanks, or click blank then click option'

Aonly

Border.create

Cexcept

Dorder.store

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'except' instead of 'only' will exclude instead of include methods.

Incorrect route name strings cause route helpers to fail.

Use only to limit methods and names to customize route names.

5fill in blank

hard

Fill all three blanks to register resource routes with a middleware group, custom parameter, and route names.

Laravel

Route::middleware('[1]')->resource('comments', CommentController::class)->parameters(['comments' => '[2]'])->names(['index' => '[3]']);

Drag options to blanks, or click blank then click option'

Aauth

Bcomment

Ccomments.index

Dguest

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'guest' middleware allows unauthenticated access.

Using plural parameter names breaks route model binding.

Incorrect route names cause URL generation errors.

Use auth middleware to protect routes, singular comment as parameter, and custom route name comments.index.

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
