Field can't update properties of casted value objects

[mihai-stancu]

Context:

Grouping columns into a value object via $casts + a custom caster.

A field defined as Text::make('Street', 'address.street') can read its value from a casted object because resolving the value relies on data_get() which traverses objects if it can.

Problem:

The same field can't be updated without workarounds because:

1. it doesn't find its attribute name inside the NovaRequest posted values (the values are posted as address_street
2. the Field::fill method relies on $model->{"address.street"} which is implemented via magic method in HasAttribute::setAttribute which doesn't rely on the reciprocal data_set() function.

Question:

Does it make sense to try to ensure this kind of reciprocity? data_get() / data_set()?

Workaround1: I've defined fillUsing() callback to resolve this temporarily.

Workaround2: you can override the magic __get method to use data_set -- this may have some unknown side effects if it circumvents other behaviors of attributes.

Sidenote: Using address->street will work of you have a (json) column named address.
