我是初级开发人员。我已经开始了我的第一份工作最近，我不得不imprement帐户锁定后，几次失败的登录尝试。
Devise已经在项目中实现了。我已经在我的用户模型上设置了使用Devise可锁定。
在特定时间内输入错误的凭据后，帐户仍处于活动状态，并且不会记录failed_attemps。
我已经遵循了这个指南HERE(https://stackoverflow.com/questions/23147889/lockable-is-not-working-in-devise)。
我一直在阅读Devise文档和各种StackOverflow问题和答案，但我无法修复我的问题。
以下是我当前的设置：
devise.rb

# ==> 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 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 = :both
  config.unlock_strategy = :time

  # Number of authentication tries before locking an account if lock_strategy
  # is failed attempts.
  # config.maximum_attempts = 20
  config.maximum_attempts = 5

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

user.rb

class User < ActiveRecord::Base
  devise :invitable, :rememberable, :database_authenticatable, :registerable,
         :recoverable, :trackable, :validatable,
         :authentication_keys => [:login], :reset_password_keys => [:login],
         :cookie_domain => :all
         :lockable

xxxxxx_添加可锁定到用户.rb

class AddLockableToUser < ActiveRecord::Migration
  def self.up
    add_column :users, :locked_at, :datetime
    add_column :users, :failed_attempts, :integer, default: 0, null: false

    execute("UPDATE users SET confirmed_at = NOW()")
  end

  def self.down
    remove_column :users, :failed_attempts
    remove_column :users, :locked_at
  end
end

rails控制台错误消息

我已经在我的模型文件夹中添加了可锁定的.rb，即使我不认为这是必要的（是吗？）

require "devise/hooks/lockable"

module Devise
  module Models
    # Handles blocking a user access after a certain number of attempts.
    # Lockable accepts two different strategies to unlock a user after it's
    # blocked: email and time. The former will send an email to the user when
    # the lock happens, containing a link to unlock it's account. The second
    # will unlock the user automatically after some configured time (ie 2.hours).
    # It's also possible to setup lockable to use both email and time strategies.
    #
    # == Options
    #
    # Lockable adds the following options to devise_for:
    #
    #   * +maximum_attempts+: how many attempts should be accepted before blocking the user.
    #   * +lock_strategy+: lock the user account by :failed_attempts or :none.
    #   * +unlock_strategy+: unlock the user account by :time, :email, :both or :none.
    #   * +unlock_in+: the time you want to lock the user after to lock happens. Only available when unlock_strategy is :time or :both.
    #   * +unlock_keys+: the keys you want to use when locking and unlocking an account
    #

如果有人能帮助指导我完成设置，我将非常感谢您的帮助。抱歉，如果这个问题是多余的或不清楚。
先谢谢你的帮助。
