unable to create record with has_mant :through relationship

An User can have many applications and an App can have many users. So I would think...

class App < ActiveRecord::Base has_and_belongs_to_many: users end

class User < ActiveRecord::Base   has_and_belongs_to_many: apps end

let me know how it goes

yes, thats correct. but i'm going to add one more field called permission in the join table. so used has_many :through

Have you got a corresponding model for Categorization?.
