Get data from a class quickly

By adding the WithData trait to a Model, Request or any class that can be magically be converted to a data object, you'll enable support for the getData method. This method will automatically generate a data object for the object it is called upon.

For example, let's retake a look at the Song model we saw earlier. We can add the WithData trait as follows:

class Song extends Model
{
    use WithData;
    
    protected $dataClass = SongData::class;
}

Now we can quickly get the data object for the model as such:

Song::firstOrFail($id)->getData(); // A SongData object

We can do the same with a FormRequest, we don't use a property here to define the data class but use a method instead:

class SongRequest extends FormRequest
{
    use WithData;
    
    protected function dataClass(): string
    {
        return SongData::class;
    }
}

Now within a controller where the request is injected, we can get the data object like this:

class SongController
{
    public function __invoke(SongRequest $request): SongData
    {
        $data = $request->getData();
    
        $song = Song::create($data->toArray());
        
        return $data;
    }
}
