custom field saving strategy

[jdion84]

i am trying to set up EAV for a model called Lead, basically allowing end-users to create custom fields for leads

the Lead model contains a hasMany relation to CustomField model

is there a way i can specify the saving strategy so that it looks like a regular nova field, but actually uses relation in the background?

for example:

$customFieldId = 3;

Text::make("Custom Field $customFieldId", "customFields.$customFieldId")
    ->saveUsing(function ($request, $model, $attribute) {
        $id = Str::replaceFirst('customFields.', '', $attribute);

        $model->customFields()->updateOrCreate([
            'id' => $id,
        ], [
            'value' => $request->input($attribute),
        ]);
    });

i know i can use JSON field in Lead model then an observer to sync the actual relations, but was wondering if theres a native way to do via nova

It sounds like you're looking for fillUsing.

If you need something to happen after the model is saved, you can return a closure.
