Customizing the toArray method

[overclocked555]

Thanks for the great package!

I'm using several models with translatable fields.
When serializing a model, I usually need to load translatable fields in the current locale. This example is described in the documentation and I am using it.
\App\Models\AppLine::get()->toArray()

However, sometimes I need to load all instances of a model with all translations.
I'm trying to add a new function toArrayWithAllTranslations() to a trait.
But I'm getting this error
\App\Models\AppLine::get()->toArrayWithAllTranslations()
BadMethodCallException Method Illuminate\Database\Eloquent\Collection::toArrayWithAllTranslations does not exist.

I guess I don't understand very well how traits work in Laravel.
I plan to also add events to all translatable models.

Where is the right place to place this function and events for use across multiple models?

app\Models\AppLine.php:

<?php

namespace App\Models;

use App\Traits\HasTranslations;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class AppLine extends Model
{
    use HasFactory, HasTranslations;

    public $translatable = ['text'];
}

app\Traits\HasTranslations.php:

<?php

namespace App\Traits;

use Spatie\Translatable\HasTranslations as BaseHasTranslations;

trait HasTranslations
{
    use BaseHasTranslations;

    public function toArray()
    {
        $attributes = $this->attributesToArray(); // attributes selected by the query
        // remove attributes if they are not selected
        $translatables = array_filter($this->getTranslatableAttributes(), function ($key) use ($attributes) {
            return array_key_exists($key, $attributes);
        });
        foreach ($translatables as $field) {
            $attributes[$field] = $this->getTranslation($field, \App::getLocale());
        }
        return array_merge($attributes, $this->relationsToArray());
    }

    public function toArrayWithAllTranslations()
    {
        return array_merge($this->attributesToArray(), $this->relationsToArray());
    }
}
