Question

I am RoR noob so this might be a simple problem for someone. I have created two models – User and Feedback and I have two tables associated with them. users and feedbacks.

Now I want to create a relationship table with user_id as one column and feeback_id as the other column.

Do I create a model or just a migration? I am confused.

Here are my user and feedback migrations.

class CreateUsers < ActiveRecord::Migration
def self.up
create_table :users do |t|
    t.string "first_name"
    t.string "last_name"
    t.string "email"
    t.string "phone"
    t.string "password_hashed"
    t.string "password_salt"
    t.boolean "isdeleted", :default => false
    t.timestamps
end
end

def self.down
drop_table :users
end
end

class CreateFeedbacks < ActiveRecord::Migration
def self.up
create_table :feedbacks do |t|
    t.text "feedback"
    t.integer "rating"  
    t.boolean "isdeleted", :default => false
    t.timestamps
end
end
def self.down
drop_table :feedbacks
end
end

Now do I create a model??? >rails generate model FeedbackUserJoinTable ? Or just a migration like this ??

class CreateFeedbackUserJoinTable < ActiveRecord::Migration
def change
create_table :feedbacks_users, :id => false do |t|
  t.integer :feedback_id
  t.integer :user_id
end
end
end

You do not need to create a model. Just create the migration as you have written 🙂
