Hi, I have an application with a relation (many to many) via a :through. I want this to be automatically updated just like with a regular many_to_many. Just like I read here: http://wiki.rubyonrails.com/rails/pages/CheckboxHABTM Is this possible? I just can't get it to work... Here are my models: class Declaration < ActiveRecord::Base #Foreign key is niet nodig, maar wordt wel aangeraden belongs_to :owner, :class_name => 'User', :foreign_key => 'user_id' has_many :declarations_payers has_many :users, :through => :declarations_payers validates_presence_of :user_id validates_numericality_of :user_id validates_presence_of :amount validates_numericality_of :amount validates_presence_of :description validates_associated :owner validates_associated :users end class DeclarationsPayer < ActiveRecord::Base belongs_to :user belongs_to :declaration validates_presence_of :declaration_id validates_numericality_of :declaration_id validates_presence_of :user_id validates_numericality_of :declaration_id validates_associated :user validates_associated :declaration end class User < ActiveRecord::Base has_many :deposits has_many :declarations_users has_many :declarations, :through => :declarations_users has_many :my_declarations, :class_name => 'Declarations', :through => :declarations_users def fullname return self.firstname + ' ' + self.lastname end end Is it possible to add a new controller and automatically add the appropriate users in the declarations_payers table? Is was trying to do something like this: <%= check_box_tag 'declaration[declarations_payer.user]', user.id %> But it just didn't work... Look here for my previous question about this application: http://groups.google.com/group/rubyonrails-talk/br... Thanks in advance!
