Question

A number of Rails 2.3 apps are using Restful Authentication but that plugin seems to have some issues with Rails 3. In upgrading to Rails 3 I have been using Devise. Is there any way to smoothly transition from Restful Authentication to Devise? Has anyone done a migration that shows how to update the User model?

Answer 1

I updated my application from Restful Authentication to Devise already. Here is my migration:

class AlterUsersForDevise < ActiveRecord::Migration
  def self.up
    remove_column :users, :name
    change_column :users, :email, :string, :default => "", :null => false, :limit => 128
    rename_column :users, :crypted_password, :encrypted_password
    change_column :users, :encrypted_password, :string, :limit => 128, :default => "", :null => false
    rename_column :users, :salt, :password_salt
    change_column :users, :password_salt, :string, :default => "", :null => false, :limit => 255
    add_column :users, :reset_password_token, :string
    change_column :users, :remember_token, :string, :limit => 255
    rename_column :users, :remember_token_expires_at, :remember_created_at

    add_column :users, :sign_in_count, :integer, :default => 0
    add_column :users, :current_sign_in_at, :datetime
    add_column :users, :last_sign_in_at, :datetime
    add_column :users, :current_sign_in_ip, :string
    add_column :users, :last_sign_in_ip, :string

    rename_column :users, :activation_code, :confirmation_token
    change_column :users, :confirmation_token, :string, :limit => 255
    rename_column :users, :activated_at, :confirmed_at

    add_column :users, :confirmation_sent_at, :datetime
  end

  def self.down
    add_column :users, :name, :string, :limit => 100, :default => ""
    rename_column :users, :encrypted_password, :crypted_password
    change_column :users, :crypted_password, :string, :limit => 40
    rename_column :users, :password_salt, :salt
    change_column :users, :salt, :string, :limit => 40
    remove_column :users, :reset_password_token
    change_column :users, :remember_token, :string, :limit => 40
    rename_column :users, :remember_created_at, :remember_token_expires_at

    remove_column :users, :sign_in_count
    remove_column :users, :current_sign_in_at
    remove_column :users, :last_sign_in_at
    remove_column :users, :current_sign_in_ip
    remove_column :users, :last_sign_in_ip

    rename_column :users, :confirmation_token, :activation_code
    change_column :users, :confirmation_token, :string, :limit => 40
    rename_column :users, :confirmed_at, :activated_at

    remove_column :users, :confirmation_sent_at
  end
end

My application isn’t live so far. So i use the password encryption from Devise instead the one from Restful Authorization. If you application is already alive, and you have active users you should configure Devise to use SHA1 from Restful Authentication to en- and decrypt passwords. Otherwise all your users must request a new password.

You can configure this in the devise initializer.

Hope that helps…
