10 Common Laravel Mistakes Beginners Make (and How to Fix Them)

10 Common Laravel Mistakes Beginners Make (and How to Fix Them) – cover image

Most Frequent Laravel Errors and How New Developers Can Avoid Them

Avoid These Laravel Pitfalls and Improve Your Development Workflow

Laravel is elegant and powerful — but even experienced developers make small mistakes that cause big problems. If you're just getting started, knowing what **not** to do can save you hours of debugging, broken apps, and bad habits.

In this post, we’ll cover the **top 10 Laravel mistakes beginners make**, explain why they’re a problem, and show you exactly how to fix them. Let’s get better together. 🛠️


1. Not Using Eloquent Relationships

Many beginners retrieve data manually using multiple queries instead of leveraging Eloquent relationships. This leads to inefficient code and logic duplication.

// Wrong: Two separate queries
$user = User::find(1);
$posts = Post::where('user_id', 1)->get();

// Right: Use the relationship
$posts = User::find(1)->posts;

2. Forgetting to Use Mass Assignment Protection

Leaving your models unprotected can expose your app to major security risks.

// Protect your model
protected $fillable = ['title', 'content'];

Or use guarded if you want a blacklist approach:

protected $guarded = ['is_admin'];

3. Ignoring Validation Logic

Skipping validation or placing it in controllers clutters your logic. Use **Form Requests** instead:

php artisan make:request StorePostRequest

Then inject it in your controller:

public function store(StorePostRequest $request)
{
    Post::create($request->validated());
}

4. Hardcoding Configuration Values

Don’t put API keys, app URLs, or secrets directly in your code. Use the .env file:

// .env
API_KEY=your-api-key
// Usage
config('services.api_key')

5. Not Using Route Names

Hardcoding URLs breaks easily and makes refactoring harder. Use named routes:

// routes/web.php
Route::get('/posts', [PostController::class, 'index'])->name('posts.index');

// In views
<a href="{{ route('posts.index') }}">Posts</a>

6. Not Caching Configs and Routes

Always cache your config and routes in production for performance:

php artisan config:cache
php artisan route:cache

7. Writing Logic in Blade Views

Business logic belongs in controllers or service classes — not in Blade templates.

// ❌ Avoid this
@if($user->role === 'admin')

// ✅ Do this
@if($user->isAdmin())

8. Not Using Tinker for Quick Testing

Laravel Tinker is your best friend for quick data testing:

php artisan tinker
User::factory()->count(10)->create();

9. Not Setting Up Laravel Debugbar

This tool shows you what queries are run and helps catch performance bottlenecks.

composer require barryvdh/laravel-debugbar --dev

10. Not Reading the Official Docs

Laravel’s documentation is world-class. Don’t skip it — read the docs often and bookmark them.
