rails_admin has_and_belongs_to_many association

[r00takaspin]

I have has_and_belongs_to_many relation in my models. I have relation beetween models Hotels and HotelRoomsTypes

class Hotel < ActiveRecord::Base
    attr_accessible hotel_room_types_attributes    
    has_and_belongs_to_many :hotel_room_types,:class_name => "HotelRoomType"
    accepts_nested_attributes_for :hotel_room_types, :allow_destroy => true
end

class HotelRoomType < ActiveRecord::Base
  attr_accessible :name
  has_and_belongs_to_many :hotels
end

when I am trying create association in rails_admin, I see following markup:

after creation, rails_admin doesn't show associations to those model. Anybody solved those problem or found patch to rails_admin?

[r00takaspin]

the problem is actual in rails_admin since version 0.4.2

You need to set inverse_of on both sides of has_and_belongs_to_many association.
