ActiveRecord and cascade removing
Hi. Please help me how to make cascade delete for this 3 classes:
class Section < ActiveRecord:Base
has_many :ad_bindings
has_many: banners, :through => :ad_bindings
end
class AdBinding < ActiveRecord:Base
belongs_to :banner
end
class Banner < ActiveRecord:Base
end
When I remove Banner, I need to remove AdBinding also, but it still
stored in database. Where I wrong?
