hi all I have a has_many_polymorphs relationship that involves the following classes: class DigilearningModule < ActiveRecord::Base has_many_polymorphs :members, :from => [:digilearning_titles, :lesson_categories, :lesson_category_groups], :through => :digilearning_module_memberships, :dependent => :destroy, :uniq => true end class DigilearningModuleMembership < ActiveRecord::Base belongs_to :digilearning_module belongs_to :member, :polymorphic => true acts_as_list :scope => :digilearning_module end The classes listed in the from option have no further associations with DigilearningModule or DigilearningModuleMembership, besides the ones dynamically added by has_many_polymorphs. As you can see, :uniq is set. This uniqueness is enforced on the has_many relationship created from DigilearningModule to (eg) DigilearningTitle, ie if i add a digilearning_title to a digilearning_module multiple times, then the digilearning_module still only has one digilearning_title. This is fine. However, the uniqueness isn''t enforced in the opposite direction. I can add a digilearning_module to the same digilearning_title multiple times. Before i go and start trying to monkey patch the has_many_polymorphs code to add this uniqueness to the dynamically created has_many associations it adds to its target classes, can anyone tell me a) if this is normal b) is there an easy fix? thanks - max -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
