未定义的局部变量或方法“encrypted_pa​​ssword”

Question

我正在使用 devise 和 omniauth 允许用户通过 twitter 访问我的网站，注册工作正常，但是当我尝试登录（使用我刚刚注册的用户）时，我不断收到以下错误：

"未定义的局部变量或方法 `encrypted_pa​​ssword' for #"

问题是我的用户模型在任何地方都没有使用“encrypted_pa​​ssword”。 我正在使用 MongoDB 和 Mongoid。 完整跟踪：

Answer 1

因为您使用的是 mongoid ORM，您需要在模型中显式定义字段。我给了你一个字段列表，顶部有注释，指定了与之配套的设计模块。您需要根据您使用的设计模块复制字段：

  ## Database authenticatable
  field :email,              :type => String, :default => ""
  field :encrypted_password, :type => String, :default => ""

  ## Password Expirable
  field :password_changed_at, :type => Time

  ## 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, :default => 0
  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
  field :deactivated,          :type => Boolean, :default => false
  field :status,               :type => String, :default => Status::PENDING

  ## Lockable
  field :failed_attempts, :type => Integer, :default => 0 # 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

  ## Invitable
  field :invitation_token, :type => String
  field :invitation_sent_at, :type => Time
  field :invitation_accepted_at, :type => Time
  field :invitation_limit, :type => Integer, :default => 0
  field :invited_by_id, :type => String
  field :invited_by_type, :type => String
