Title
Body
I have two classes: Parent and Child with Child: belongs_to :parent and Parent has_many :children, :dependent => :destroy The problem is that I want to check that there is always at least one child present, so I have a before_destroy method in Child that abort the destroy if it is the only child belonging to its parent. And, if I want to destroy the parent, it will call the before_destroy callback on every child, but when there is one child, it will abort the destroy, so the parent will never get destroyed. How can I tell the child to call the before_destroy callback only if it's not being destroyed because of its parent? Thanks!
