Hello, I am using the boot() method in my own plugin to extend an existing form in another plugin using Event::listen('backend.form.extendFields', function($widget) {}). I am able to add regular fields, but once I try to add a featured_image field of type fileupload, I get the following error:

Call to undefined method Illuminate\Database\Query\Builder::featured_image()

What's causing this?

You probably need to also extend the target model with the file relationship. Try adding something like this to your boot method.

ModelBeingExtended::extend(function ($model) {
    $model->attachOne['featured_image'] = ['System\Models\File'];
});

Yes, I had already did that, but the problem seemed to be quite trivial: I was extending the model inside the anonymous function that was being passed to Event::listen(). I moved it out of there and it started working as expected.
