Devise有一个内置解决方案,:lockable可以选择Devise Lockable Documentation中的选项

您必须将设置lock_strategy设置为:failed_attempts.

步骤1 设置config/initializers/devise.rb使用:

# Defines which strategy will be used to lock an account.
config.lock_strategy = :failed_attempts

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

# Defines which strategy will be used to unlock an account.
# :time  = Re-enables login after a certain amount of time (see :unlock_in below)
config.unlock_strategy = :time

# Number of authentication tries before locking an account if lock_strategy
# is failed attempts.
config.maximum_attempts = 3

# Time interval to unlock the account if :time is enabled as unlock_strategy.
config.unlock_in = 2.hours

第2步 你应该将锁定添加到你的模型如下:

class Example < ActiveRecord::Base
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, 
         :lockable

步骤3 生成迁移以使设计工作

class AddLockableToExamples < ActiveRecord::Migration
  def change
    add_column :examples, :failed_attempts, :integer, default: 0
    add_column :examples, :unlock_token, :string
    add_column :examples, :locked_at, :datetime
  end
end
