I have two models A and B.
They are connected as follow (relevant bits only):
class A
has_many :bs, :dependent => :destroy
def destroy_permitted?
true
end
end
class B
def destroy_permitted?
false
end
end
As you can see, I do not want the user to be able to delete B.
However, I do want the user to be able to delete A. And if A is
deleted, I do want all of it's B's to be deleted as well.
Is it possible to express this desire?
The code above thows a Hobo::PermissionDeniedError, which is to be
expected.
But is there a way to detect that a cascading delete is being
performed within B's destroy_permitted? and allow it to happen?
