A trait to make Eloquent models translatable

Latest Version on Packagist Software License Build Status Quality Score StyleCI Total Downloads

This package contains a trait to make Eloquent models translatable. Translations are stored as json. There is no extra table needed to hold them.

Once the trait is installed on the model you can do these things:

$newsItem = new NewsItem; // This is an Eloquent model
$newsItem
   ->setTranslation('name', 'en', 'Name in English')
   ->setTranslation('name', 'nl', 'Naam in het Nederlands')
   ->save();
   
$newsItem->name; // Returns 'Name in English' given that the current app locale is 'en'
$newsItem->getTranslation('name', 'nl'); // returns 'Naam in het Nederlands'

app()->setLocale('nl');

$newsItem->name; // Returns 'Naam in het Nederlands'

Installation

You can install the package via composer:

composer require spatie/laravel-translatable

The package will automatically register itself.

If you want to change add fallback_locale, you must publish the config file:

php artisan vendor:publish --provider="Spatie\Translatable\TranslatableServiceProvider"

This is the contents of the published file:

return [
  'fallback_locale' => 'en',
];

Making a model translatable

The required steps to make a model translatable are:

  • First, you need to add the Spatie\Translatable\HasTranslations-trait.
  • Next, you should create a public property $translatable which holds an array with all the names of attributes you wish to make translatable.
  • Finally, you should make sure that all translatable attributes are set to the text-datatype in your database. If your database supports json-columns, use that.

Here's an example of a prepared model:

use Illuminate\Database\Eloquent\Model;
use Spatie\Translatable\HasTranslations;

class NewsItem extends Model
{
    use HasTranslations;
    
    public $translatable = ['name'];
}

Available methods

Getting a translation

The easiest way to get a translation for the current locale is to just get the property for the translated attribute. For example (given that name is a translatable attribute):

$newsItem->name;

You can also use this method:

public function getTranslation(string $attributeName, string $locale) : string

This function has an alias named translate.

Getting all translations

You can get all translations by calling getTranslations() without an argument:

$newsItem->getTranslations();

Setting a translation

The easiest way to set a translation for the current locale is to just set the property for a translatable attribute. For example (given that name is a translatable attribute):

$newsItem->name = 'New translation';

To set a translation for a specific locale you can use this method:

public function setTranslation(string $attributeName, string $locale, string $value)

To actually save the translation, don't forget to save your model.

$newsItem->setTranslation('name', 'en', 'Updated name in English');

$newsItem->save();

Validation

  • if you want to validate an attribute for uniqueness before saving/updating the db, you might want to have a look at laravel-unique-translation which is made specifically for laravel-translatable.

Forgetting a translation

You can forget a translation for a specific field:

public function forgetTranslation(string $attributeName, string $locale)

You can forget all translations for a specific locale:

public function forgetAllTranslations(string $locale)

Getting all translations in one go

public function getTranslations(string $attributeName): array

Setting translations in one go

public function setTranslations(string $attributeName, array $translations)

Here's an example:

$translations = [
   'en' => 'Name in English',
   'nl' => 'Naam in het Nederlands'
];

$newsItem->setTranslations('name', $translations);

Events

TranslationHasBeenSet

Right after calling setTranslation the Spatie\Translatable\Events\TranslationHasBeenSet-event will be fired.

It has these properties:

/** @var \Illuminate\Database\Eloquent\Model */
public $model;

/** @var string  */
public $attributeName;

/** @var string  */
public $locale;

public $oldValue;
public $newValue;

Creating models

You can immediately set translations when creating a model. Here's an example:

NewsItem::create([
   'name' => [
      'en' => 'Name in English'
      'nl' => 'Naam in het Nederlands'
   ],
]);

Querying translatable attributes

If you're using MySQL 5.7 or above, it's recommended that you use the json data type for housing translations in the db. This will allow you to query these columns like this:

NewsItem::where('name->en', 'Name in English')->get();

Using translations in json responses

The easiest way to add translations to json reponse is to override the toArray method on your model.

Here's a quick example:

// in your model

    /**
     * Convert the model instance to an array.
     *
     * @return array
     */
    public function toArray()
    {
        $attributes = parent::toArray();
        
        foreach ($this->getTranslatableAttributes() as $name) {
            $attributes[$name] = $this->getTranslation($name, app()->getLocale());
        }
        
        return $attributes;
    }
}
