Translatable slugs

Use the HasTranslatableSlug trait together with spatie/laravel-translatable to store one slug per locale.

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Spatie\Sluggable\HasTranslatableSlug;
use Spatie\Sluggable\SlugOptions;
use Spatie\Translatable\HasTranslations;

class Article extends Model
{
    use HasTranslations;
    use HasTranslatableSlug;

    public $translatable = ['title', 'slug'];

    public function getSlugOptions(): SlugOptions
    {
        return SlugOptions::create()
            ->generateSlugsFrom('title')
            ->saveSlugsTo('slug');
    }
}

The slug column must hold a JSON value; every translatable attribute in $translatable (including the slug itself) is stored as a locale-keyed object.

##Generating slugs from a callable per locale

When using a callable, instantiate SlugOptions with createWithLocales(). The callable receives the model and the current locale.

public function getSlugOptions(): SlugOptions
{
    return SlugOptions::createWithLocales(['en', 'nl'])
        ->generateSlugsFrom(fn (Article $article, string $locale) => "{$locale} {$article->id}")
        ->saveSlugsTo('slug');
}

##Routing

Use Laravel's implicit route model binding, pointing at the slug column.

Route::get('/articles/{article:slug}', fn (Article $article) => $article);

HasTranslatableSlug handles the locale-aware JSON lookup in resolveRouteBindingQuery().

##Finding models by slug

HasTranslatableSlug ships its own findBySlug() that searches the current locale and the application fallback locale.

$article = Article::findBySlug('my-article');

##Self-healing URLs

selfHealing() works with the translatable trait. The route key uses the slug for the current locale; stale slugs trigger the same redirect flow described in Self-healing URLs.

##Getting the route key for a specific locale

Use getLocalizedRouteKey() to retrieve the route key for a given locale without permanently changing the model's active locale.

$article->getLocalizedRouteKey('nl'); // "nederlandse-titel-5"

The method swaps in the requested locale, calls getRouteKey(), and restores the original locale via try/finally, so the model is always left as it was found, including when getRouteKey() throws.
