I'm having a problem with a habtm association. I'm not sure if I set them up wrong or if I'm trying to work with the models incorrectly. Either way I welcome any clarification on why this isn't working.
My models look like this:
model/user.rb
Is there a reason that you have t.column :id, :number in the roles_users table?
i've been trying a number of things. i originally had no "id" columns defined because i didn't think you needed to create them manually.
Hi Mike. I think you want this:
class CreateRolesUsers < ActiveRecord::Migration def self.up create_table :roles_users, :id => false do |t| t.column :role_id, :integer t.column :user_id, :integer end end
Essentially, you don't want to allow ActiveRecord to give your join tables an id field which is a primary key. For more information, see my post here:
