filter in a foreign key column

[LorenzoAlu]

Hi everybody.

I've a question.
It's possible use the Orchid filters in Resource to filters other params in a relation column?
For example.... if I've a foreign key call user_id on Post model how can I make a filters with use other params of that relation in PostResource?
I try but filter works only with user_id , so I can filters params only with numeric value.
I would like use email of User to filters results instead of user_id in Post model.
