Korzystanie z Devise 2.1.2 i Rails 3.2.6

Robię to pytanie na wypadek, gdyby inni natknęli się na ten problem, ponieważ znalazłem dla niego małą i rozproszoną dokumentację.

Ten błąd może wystąpić, jeśli spróbujesz skonfigurowaćDevise jak zamykany.

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

Oznacza to, że twój model nie ma odpowiednich atrybutów.

Wymagania wstępne: Skonfiguruj następujące ustawienia w config / initializers / 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 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

Skonfiguruj swój model tak, aby zawierałdevise :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
