How can I add new attributes into my migrate?

Question

I currently have the migrate thing like:

class CreateUsers < ActiveRecord::Migration
  def change
    create_table :users do |t|
      t.string :name
      t.string :email
      t.string :encrypted_password
      t.string :salt

      t.timestamps
    end
  end
end

now, if I wanna add two new attributes into this file, one is: t.string :type , and the other one is: t.string :memory_token , how can I do this please?

Answer 1

If you have already run the migration you will have to create a new one.

rails g migration AddTypeToUsers

And then in the migration file you can edit in

change_table :users do |t|
  t.string :type
  t.string :memory_token
end

Then run a migration rake db:migrate to make the changes

If you haven't run the migration then you can simply add

  t.string :type
  t.string :memory_token

To that file you have showed us and then run your migration
