使用 Devise 2.1.2 和 Rails 3.2.6

我做这个问答是为了防止其他人遇到这个问题,因为我发现它的文档很少而且分散。

如果您尝试将 Devise 设置为可锁定,则可能会出现此错误。

undefined local variable or method `locked_at' for [someClass]

这意味着您的模型没有适当的属性。

先决条件:在 config/initializers/devise.rb 中设置以下内容

# ==> Configuration for :lockable
# Defines which strategy will be used to lock an account.
# :failed_attempts = Locks an account after a number of failed attempts to sign in.
# :none = No lock strategy. You should handle locking by yourself.
config.lock_strategy = :failed_attempts

# Defines which key will be used when locking and unlocking an account
config.unlock_keys = [ :email ]

# Defines which strategy will be used to unlock an account.
# :email = Sends an unlock link to the user email
# :time = Re-enables login after a certain amount of time (see :unlock_in below)
# :both = Enables both strategies
# :none = No unlock strategy. You should handle unlocking by yourself.
config.unlock_strategy = :email

# Number of authentication tries before locking an account if lock_strategy
# is failed attempts.
config.maximum_attempts = 20

# Time interval to unlock the account if :time is enabled as unlock_strategy.
# config.unlock_in = 1.hour

设置您的模型以包含devise :lockable:

class Example < ActiveRecord::Base
# Include default devise modules. Others available are:
# :token_authenticatable, :confirmable,
# :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable, :lockable

最佳答案

Devise 在您的模型上需要这三个属性。因此,生成以下迁移并运行它。

class AddLockableToExamples < ActiveRecord::Migration
def change
add_column :examples, :failed_attempts, :integer, default: 0
add_column :examples, :unlock_token, :string # Only if unlock strategy is :email or :both
add_column :examples, :locked_at, :datetime
end
end

希望这可以节省其他人在 google 上花费的时间。
