🔍 Introduction

In Laravel, passing IDs in routes is common. But what if you could automatically load models based on the URL, and get rid of all those manual Model::find() calls? That’s where Route Model Binding comes in — elegant, clean, and built into Laravel.

🔧 What Is Route Model Binding?

Instead of:

php
Route::get('/blog/{id}', [BlogController::class, 'show']);

You can do:

php

Route::get('/blog/{blog}', [BlogController::class, 'show']);

Laravel will auto-resolve {blog} from the Blog model using the id.

✅ Step-by-Step Example

1. Define Your Route:

php

Route::get('/projects/{project}', [ProjectController::class, 'show']);

2. Controller Method:

php

public function show(Project $project)
{
    return view('projects.show', compact('project'));
}

No need to manually call Project::find($id) — Laravel already did that!

🆕 Custom Key Binding

Want to use a slug instead of id?

In your Project model:

php

public function getRouteKeyName()
{
    return 'slug';
}

Now you can visit:
/projects/my-first-laravel-app and Laravel will match it via the slug field.

🔐 Bonus: Type Safety + 404 Handling

If a record is not found, Laravel automatically throws a 404 — no extra checks needed.

🧠 Conclusion

Route Model Binding is one of those Laravel features that makes your code more readable, maintainable, and secure — with zero extra effort. Start using it and your controllers will thank you.
