Question

I have User model and Feedback model and User model has user_type attribute.
Feedback model also has user_id attribute.I want to add user_type column to Feedback model the same as in User model.For instance after the migration it should be like that

User
id:123
user_type: "customer"

Feedback
id:56
user_id:123
user_type : "customer"

Answer 1

Why you are putting user_type in feedback table too. You can retrieve it from user_id by using rails association.

class User < ActiveRecord::Base
  has_many :feedback
end 

class Feedback < ActiveRecord::Base
  belongs_to :user
end 

To retreive user_type from feedback object use @feedback.user.user_type
