Display only some field for relation model

[DavidGuillerm]

Hi ,
I don't figure out how to display only some columns for a relational model.
I have a Model (Siteconfig) which has a Building relation with building_id. My request is like this :

$allconfigs = Siteconfig::with(['building:id,name'])->get()

I would like so to display only the id and name for the Building model, I tried this :

* @response array{id: int, building_id: int, building: {id: int}}[]

also this

* @response array{id: int, building_id: int, building: \App\Models\Building}[]

For the last one, it shows me all the fields for the Building model, but I only want id and name showing.

Do you know how to do this ?
