rails pg db for Devise Users的undefined方法`database_authenticatable’

undefined method database_authenticatable' for #

迁移是：

 class DeviseCreateUsers  false t.recoverable t.rememberable t.trackable t.timestamps end add_index :users, :email, :unique => true add_index :users, :reset_password_token, :unique => true end def self.down drop_table :users end end 

Answer 1

如果我没有弄错的话，设计改变了它生成的迁移风格

 create_table(:user) do |t| t.database_authenticatable end 

至

 create_table(:user) do |t| ## Database authenticatable t.string :email, :null => false, :default => "" t.string :encrypted_password, :null => false, :default => "" end 

版本2.0之后。

这对我有用：

 create_table(:users) do |t| t.string :email, :null => false, :default => "" t.string :encrypted_password, :null => false, :default => "" ## Recoverable t.string :reset_password_token t.datetime :reset_password_sent_at ## Rememberable t.datetime :remember_created_at ## Trackable t.integer :sign_in_count, :default => 0 t.datetime :current_sign_in_at t.datetime :last_sign_in_at t.string :current_sign_in_ip t.string :last_sign_in_ip # t.encryptable # t.confirmable # t.lockable :lock_strategy => :failed_attempts, :unlock_strategy => :both # t.token_authenticatable t.timestamps end
