Question

I have a user table which contains the user registration details such as username, password and email…

How can I add a profile table to store name, country, age etc… ?

Do I simply create the table and use JOIN to select the data or is there another way to do this using Ruby on Rails?

Answer 1

Use a migration to add those columns to the user model. From the sounds of it I don’t think you would actually need a separate model for those attributes.

your migration might look something like

rails g migration AddProfileDataToUsers

class AddProfileDataToUsers < ActiveRecord::Migration
  change_table :users do |t|
    t.add_column :name, :string
    t.add_column :country, :string...
    #whatever else you want to add to the user model here
    end
end

Then you can pull the data as you need it by doing @user.country or something along those lines. Hope this helps
