# Route Model Binding and Eloquent-Sluggable
Route Model Binding is easy to implement with only minor configuration to your models.
## Implicit Binding
Implicit binding requires adding a `getRouteKeyName()` method to your model that returns the name
of the slug field:
```php
use Cviebrock\EloquentSluggable\Sluggable;
use Cviebrock\EloquentSluggable\SluggableScopeHelpers;
use Illuminate\Database\Eloquent\Model;
class Post extends Model
{
use Sluggable, SluggableScopeHelpers;
public function sluggable(): array
{
return [
'slug' => [
'source' => 'title',
]
];
}
/**
* Get the route key for the model.
*
* @return string
*/
public function getRouteKeyName(): string
{
return 'slug';
}
}
```
From there, you can set up your routes as described in the Eloquent documentation:
```php
Route::get('api/posts/{post}', function(App\Post $post): string {
return $post->title;
});
```
In this example, since the Eloquent type-hinted `$post` variable defined on the route
matches the {post} segment in the route's URI, Laravel will automatically inject the
model instance that has a slug matching the corresponding value from the request URI.
Further, if you are using the [SluggableScopeHelpers](SCOPE-HELPERS.md) trait, you can bind
the default slug to the route parameter with:
```php
public function getRouteKeyName(): string
{
return $this->getSlugKeyName();
}
```
## Explicit Binding
You can also use the `RouteServiceProvider::boot` method as described in the
[Laravel Documentation](https://laravel.com/docs/routing#route-model-binding) to
handle explicit route model binding.
