README

This package adds support for spatie/laravel-sluggable package to models that use the UnderscoreTranslatable trait from the esign/laravel-underscore-translatable package.

Installation

You can install the package via composer:

composer require esign/laravel-underscore-sluggable

Upgrading

When updating to a new version, check the upgrade guide.

Usage

To support slug generation for models that use the UnderscoreTranslatable trait, you may add the HasTranslatableSlug trait to your models. Next up, you should define the getSlugOptions method on your model, which should be created using the createWithLocales method.

namespace App\Models;

use Esign\UnderscoreSluggable\HasTranslatableSlug;
use Esign\UnderscoreTranslatable\UnderscoreTranslatable;
use Illuminate\Database\Eloquent\Model;
use Spatie\Sluggable\SlugOptions;

class Post extends Model
{
    use UnderscoreTranslatable;
    use HasTranslatableSlug;

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

    public function getSlugOptions(): SlugOptions
    {
        return SlugOptions::createWithLocales(['en', 'nl'])
            ->generateSlugsFrom('title')
            ->saveSlugsTo('slug');
    }
}

Generating a slug from a callback

You may also generate a slug from a callback by passing a closure to the generateSlugsFrom method. This callback will receive the model instance and the current locale as arguments:

namespace App\Models;

use Esign\UnderscoreSluggable\HasTranslatableSlug;
use Esign\UnderscoreTranslatable\UnderscoreTranslatable;
use Illuminate\Database\Eloquent\Model;
use Spatie\Sluggable\SlugOptions;

class Post extends Model
{
    use UnderscoreTranslatable;
    use HasTranslatableSlug;

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

    public function getSlugOptions(): SlugOptions
    {
        return SlugOptions::createWithLocales(['en', 'nl'])
            ->generateSlugsFrom(function (Model $model, string $locale) {
                return $model->getTranslation('title', $locale) . '-' . $model->id;
            })
            ->saveSlugsTo('slug');
    }
}

For more configuration options, please refer to the spatie/laravel-sluggable documentation.

Self-healing URLs

Self-healing URLs combine the slug with the model's primary key (e.g. hello-world-5). When the slug changes, requests to the old URL are automatically redirected with a 308 to the canonical URL — so existing links never break.

Enable it by calling ->selfHealing() on your SlugOptions:

public function getSlugOptions(): SlugOptions
{
    return SlugOptions::createWithLocales(['en', 'nl'])
        ->generateSlugsFrom('title')
        ->saveSlugsTo('slug')
        ->selfHealing();
}

With this in place, route model binding will resolve hello-world-5 to the correct model. If the slug portion is stale (e.g. old-title-5), Laravel will issue a 308 Permanent Redirect to the current canonical URL.

Finding a model by slug

You may use findBySlug to retrieve a model by the slug of the active locale.

$post = Post::findBySlug('my-first-post');

To further scope the query, pass an additional query callback as the third argument:

$post = Post::findBySlug('my-first-post', ['*'], function ($query) {
    $query->where('status', 'published');
});
