我想在我的应用程序中为帐户持有人用户添加订阅类型功能，以便在登录尝试失败的情况下，他们将无法访问他们的帐户。注意：我不想从数据库中删除他们的帐户。我已经安装devise-2.1.2在我的应用程序中。有没有人知道如何做到这一点？我是新手，Ruby on rails所以如果您解释一下步骤，这将对我非常有帮助。

设计有一个内置的解决方案，带有设计可锁定文档:lockable中的选项检查

您必须将集合lock_strategy设置为:failed_attempts.

第 1 步 设置您的 config/initializers/devise.rb 以使用：

# 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 您应该将可锁定的模型添加到您的模型中，如下所示：

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

问候！！
