ruby on rails password 如何使Devise可以鎖定失敗次數




rails devise role (3)

最好的一個請刪除:可從用戶模型鎖定

使用Devise 2.1.2和Rails 3.2.6

我正在做這個問答,以防萬一其他人遇到這個問題,因為我發現它很少和分散的文檔。

如果您嘗試將Devise設置為可鎖定,則可能會發生此錯誤。

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

這意味著您的模型沒有適當的屬性。

先決條件:在config / initializers / devise.rb中設置以下內容

# ==> 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

設置模型以包含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

Answer #1

Devise需要在模型上使用這三個屬性。 因此,生成以下遷移並運行它。

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

希望這可以節省別人的谷歌時間。


Answer #2

只需在設計遷移中取消註釋這些字符串:

  ## Lockable
  # t.integer  :failed_attempts, :default => 0 # Only if lock strategy is :failed_attempts
  # t.string   :unlock_token # Only if unlock strategy is :email or :both
  # t.datetime :locked_at
