How To: Upgrade to Devise 2.0 migration schema style

Since Devise 2.0, it no longer includes helpers for your migrations. Instead, it simply lists the database fields explicitly. This page shows the before and after of the migrations so you can easily compare and update your code.

Active Record

Before

create_table(TABLE_NAME) do |t|
  t.database_authenticatable :null => false
  t.recoverable
  t.rememberable
  t.trackable

  # t.encryptable
  # t.confirmable
  # t.lockable :lock_strategy => :failed_attempts, :unlock_strategy => :both
  # t.token_authenticatable
end

After

create_table(TABLE_NAME) do |t|
  ## Database authenticatable
  t.string :email,              :null => false
  t.string :encrypted_password, :null => false

  ## Recoverable
  t.string   :reset_password_token
  t.datetime :reset_password_sent_at

  ## Rememberable
  t.datetime :remember_created_at

  ## Trackable
  t.integer  :sign_in_count
  t.datetime :current_sign_in_at
  t.datetime :last_sign_in_at
  t.string   :current_sign_in_ip
  t.string   :last_sign_in_ip

  ## Encryptable
  # t.string :password_salt

  ## Confirmable
  # t.string   :confirmation_token
  # t.datetime :confirmed_at
  # t.datetime :confirmation_sent_at
  # t.string   :unconfirmed_email # Only if using reconfirmable

  ## Lockable
  # t.integer  :failed_attempts, :default => 0 # Only if lock strategy is :failed_attempts
  # t.string   :unlock_token # Only if unlock strategy is :email or :both
  # t.datetime :locked_at

  # Token authenticatable
  # t.string :authentication_token
end

Mongoid

Before Devise 2.0, Devise automatically configured your MongoDB. This is no longer true. In order to upgrade, you need to set Devise.apply_schema to false and add the following to your model according to the strategies you are using:

  ## Database authenticatable
  field :email,              :type => String, :null => false
  field :encrypted_password, :type => String, :null => false

  ## Recoverable
  field :reset_password_token,   :type => String
  field :reset_password_sent_at, :type => Time

  ## Rememberable
  field :remember_created_at, :type => Time

  ## Trackable
  field :sign_in_count,      :type => Integer
  field :current_sign_in_at, :type => Time
  field :last_sign_in_at,    :type => Time
  field :current_sign_in_ip, :type => String
  field :last_sign_in_ip,    :type => String

  ## Encryptable
  # field :password_salt, :type => String

  ## Confirmable
  # field :confirmation_token,   :type => String
  # field :confirmed_at,         :type => Time
  # field :confirmation_sent_at, :type => Time
  # field :unconfirmed_email,    :type => String # Only if using reconfirmable

  ## Lockable
  # field :failed_attempts, :type => Integer # Only if lock strategy is :failed_attempts
  # field :unlock_token,    :type => String # Only if unlock strategy is :email or :both
  # field :locked_at,       :type => Time

  # Token authenticatable
  # field :authentication_token, :type => String
