I have this following use case.
_id, name, base1_id
so basically… base2 is a linked relation, parent -> child
_id, base1_id, base2_id
base2_id is a relation that brings all the linked (children) of base 1… I need to be able to pick one or several but not all (like it is linked), but I need to make sure that they are children of the
base1_id, so I need some kind of validation there.
Any idea how to fulfill this use case?
