Automatically set attributes using Laravel Eloquent

I have some attributes, that I need to set automatically when using create() or save() methods.

Model:

class SampleModel extends Model
{
    protected $guarded = ['id'];

    public function setRandomColumnAttribute($value=null)
    {
        if(!is_string($hostname)){
            $value = "I set the value here";
        }

        $this->attributes['random_column'] = $value;
    }
}

Controller

use App\SampleModel;

class SomeController extends Controller
{
    public function something()
    {
        SampleModel::create([
            'name' => 'Jeff',
        ]);

        // or instead of the above:
        // $model = new SampleModel;
        // $model->name = 'Jeff';
        // $model->save();
    }
}

I need to save random_column value, that is defined in the Model itself as you see, without passing it from the controller.

Please note if I use:

    SampleModel::create([
        'name'          => 'Jeff',
        'random_column' => true // or anything other than string
    ]);

It works and set the value, but is there any way to avoid passing this every time and just set it automatically in the Model?

Did you try observers? Add boot() method to your SampleModel:

protected static function boot()
{
    parent::boot();
    static::creating(function (SampleModel $model) {
        $model->random_column = 'Random column';
    });
}

Creating will trigger everytime a ->create() is called on a SampleModel.
