I am looking for a many-to-many association within the child models. Something like this below. Can you please guide what's the best way to do it.
Parent
class A < ActiveRecord::Base
end
Child1
class B < A
has_many :bc
has_many :c ,through: :bc
end
Child2
class C < A
has_many :bc
has_many :b, through: :bc
end
