Hello, Here is the use case. I have 2 Entities A & B (Models) that can be linked together using a m2m relationships in a "link" table. the 2 Entities each have a 'category' field and there are some business rules like Items of A with category C1 are not allowed to be linked to Items of B with category C2
Now i need to ensure that, whatever the view / controller used to attempt to create the new link, my central validation get a chance to accept or refuse the creation of Links . I was thinking that i need a custom validator, but i had the feeling that custom validator are only for form and not for models?
