Generate slugs when saving Eloquent models

v1.4.0 2022-02-11 16:36 UTC

README

This package was created by Spatie. We have forked it so we can add new features we need and so we are not dependend on Spatie before we can upgrade to new Laravel versions.

$model = new EloquentModel();
$model->name = 'activerecord is awesome';
$model->save();

echo $model->slug; // ouputs "activerecord-is-awesome"

The slugs are generated with Laravels Str::slug method, whereby spaces are converted to '-'.

Installation

You can install the package via composer:

composer require marshmallow/sluggable

Usage

Your Eloquent models should use the Marshmallow\Sluggable\HasSlug trait and the Marshmallow\Sluggable\SlugOptions class.

The trait contains an abstract method getSlugOptions() that you must implement yourself.

Your models' migrations should have a field to save the generated slug to.

Here's an example of how to implement the trait:

namespace App;

use Marshmallow\Sluggable\HasSlug;
use Marshmallow\Sluggable\SlugOptions;
use Illuminate\Database\Eloquent\Model;

class YourEloquentModel extends Model
{
    use HasSlug;

    /**
     * Get the options for generating the slug.
     */
    public function getSlugOptions() : SlugOptions
    {
        return SlugOptions::create()
            ->generateSlugsFrom('name')
            ->saveSlugsTo('slug');
    }
}

With its migration:

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateYourEloquentModelTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('your_eloquent_models', function (Blueprint $table) {
            $table->increments('id');
            $table->string('slug'); // Field name same as your `saveSlugsTo`
            $table->string('name');
            $table->timestamps();
        });
    }
}

To use the generated slug in routes, remember to use Laravel's implicit route model binding:

namespace App;

use Marshmallow\Sluggable\HasSlug;
use Marshmallow\Sluggable\SlugOptions;
use Illuminate\Database\Eloquent\Model;

class YourEloquentModel extends Model
{
    use HasSlug;

    /**
     * Get the options for generating the slug.
     */
    public function getSlugOptions() : SlugOptions
    {
        return SlugOptions::create()
            ->generateSlugsFrom('name')
            ->saveSlugsTo('slug');
    }

    /**
     * Get the route key for the model.
     *
     * @return string
     */
    public function getRouteKeyName()
    {
        return 'slug';
    }
}

Want to use multiple field as the basis for a slug? No problem!

public function getSlugOptions() : SlugOptions
{
    return SlugOptions::create()
        ->generateSlugsFrom(['first_name', 'last_name'])
        ->saveSlugsTo('slug');
}

You can also pass a callable to generateSlugsFrom.

By default the package will generate unique slugs by appending '-' and a number, to a slug that already exists.

You can disable this behaviour by calling allowDuplicateSlugs.

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

You can also put a maximum size limit on the created slug:

public function getSlugOptions() : SlugOptions
{
    return SlugOptions::create()
        ->generateSlugsFrom('name')
        ->saveSlugsTo('slug')
        ->slugsShouldBeNoLongerThan(50);
}

The slug may be slightly longer than the value specified, due to the suffix which is added to make it unique.

You can also use a custom separator by calling usingSeparator

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

To set the language used by Str::slug you may call usingLanguage

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

You can also override the generated slug just by setting it to another value than the generated slug.

$model = EloquentModel:create(['name' => 'my name']); //slug is now "my-name";
$model->slug = 'my-custom-url';
$model->save(); //slug is now "my-custom-url";

If you don't want to create the slug when the model is initially created you can set use the doNotGenerateSlugsOnCreate() function.

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

Similarly, if you want the slug to be generated again on model updates, call generateSlugsOnUpdate().

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

This can be helpful for creating permalinks that don't change until you explicitly want it to.

$model = EloquentModel:create(['name' => 'my name']); //slug is now "my-name";
$model->save();

$model->name = 'changed name';
$model->save(); //slug stays "my-name"

If you want to explicitly update the slug on the model you can call generateSlug() on your model at any time to make the slug according to your other options. Don't forget to save() the model to persist the update to your database.
