我有一个Rails 4电子商务应用，我使用Devise进行用户身份验证。
我也使用ActiveAdmin，它也使用Devise进行身份验证。
我遇到的问题是我随机登陆。几乎看起来会话被破坏了，但会话cookie保持不变。我尝试删除了Devise skip_session_storage选项，但没有骰子。
我使用:dalli_store在memcached中存储会话。
我的devise.rb看起来像：
# require 'devise-encryptable'
# Use this hook to configure devise mailer, warden hooks and so forth.
# Many of these configuration options can be set straight in your model.
Devise.setup do |config|
# The secret key used by Devise. Devise uses this key to generate
# random tokens. Changing this key will render invalid all existing
# confirmation, reset password and unlock tokens in the database.
config.secret_key = '<secret_key>'
# ==> Mailer Configuration
# Configure the e-mail address which will be shown in Devise::Mailer,
# note that it will be overwritten if you use your own mailer class
# with default "from" parameter.
# TODO:
config.mailer_sender = 'noreply@example.com'
# Configure the class responsible to send e-mails.
config.mailer = 'Store::UserMailer'
# ==> ORM configuration
# Load and configure the ORM. Supports :active_record (default) and
# :mongoid (bson_ext recommended) by default. Other ORMs may be
# available as additional gems.
require 'devise/orm/active_record'
# ==> Configuration for any authentication mechanism
# Configure which keys are used when authenticating a user. The default is
# just :email. You can configure it to use [:username, :subdomain], so for
# authenticating a user, both parameters are required. Remember that those
# parameters are used only when authenticating and not when retrieving from
# session. If you need permissions, you should implement that in a before filter.
# You can also supply a hash where the value is a boolean determining whether
# or not authentication should be aborted when the value is not present.
# config.authentication_keys = [ :email ]
# Configure parameters from the request object used for authentication. Each entry
# given should be a request method and it will automatically be passed to the
# find_for_authentication method and considered in your model lookup. For instance,
# if you set :request_keys to [:subdomain], :subdomain will be used on authentication.
# The same considerations mentioned for authentication_keys also apply to request_keys.
# config.request_keys = []
# Configure which authentication keys should be case-insensitive.
# These keys will be downcased upon creating or modifying a user and when used
# to authenticate or find a user. Default is :email.
config.case_insensitive_keys = [ :email ]
# Configure which authentication keys should have whitespace stripped.
# These keys will have whitespace before and after removed upon creating or
# modifying a user and when used to authenticate or find a user. Default is :email.
config.strip_whitespace_keys = [ :email ]
# Tell if authentication through request.params is enabled. True by default.
# It can be set to an array that will enable params authentication only for the
# given strategies, for example, `config.params_authenticatable = [:database]` will
# enable it only for database (email + password) authentication.
# config.params_authenticatable = true
# Tell if authentication through HTTP Auth is enabled. False by default.
# It can be set to an array that will enable http authentication only for the
# given strategies, for example, `config.http_authenticatable = [:token]` will
# enable it only for token authentication. The supported strategies are:
# :database = Support basic authentication with authentication key + password
# :token = Support basic authentication with token authentication key
# :token_options = Support token authentication with options as defined in
# http://api.rubyonrails.org/classes/ActionController/HttpAuthentication/Token.html
# config.http_authenticatable = false
# If http headers should be returned for AJAX requests. True by default.
config.http_authenticatable_on_xhr = false
# The realm used in Http Basic Authentication. 'Application' by default.
# config.http_authentication_realm = 'Application'
# It will change confirmation, password recovery and other workflows
# to behave the same regardless if the e-mail provided was right or wrong.
# Does not affect registerable.
# config.paranoid = true
# By default Devise will store the user in session. You can skip storage for
# :http_auth and :token_auth by adding those symbols to the array below.
# Notice that if you are skipping storage for all authentication paths, you
# may want to disable generating routes to Devise's sessions controller by
# passing :skip => :sessions to `devise_for` in your config/routes.rb
# config.skip_session_storage = [:http_auth]
# By default, Devise cleans up the CSRF token on authentication to
# avoid CSRF token fixation attacks. This means that, when using AJAX
# requests for sign in and sign up, you need to get a new CSRF token
# from the server. You can disable this option at your own risk.
config.clean_up_csrf_token_on_authentication = true
# ==> Configuration for :database_authenticatable
# For bcrypt, this is the cost for hashing the password and defaults to 10. If
# using other encryptors, it sets how many times you want the password re-encrypted.
#
# Limiting the stretches to just one in testing will increase the performance of
# your test suite dramatically. However, it is STRONGLY RECOMMENDED to not use
# a value less than 10 in other environments.
config.stretches = Rails.env.test? ? 1 : 10
# Setup a pepper to generate the encrypted password.
config.pepper = '<pepper_value>'
# ==> Configuration for :confirmable
# A period that the user is allowed to access the website even without
# confirming his account. For instance, if set to 2.days, the user will be
# able to access the website for two days without confirming his account,
# access will be blocked just in the third day. Default is 0.days, meaning
# the user cannot access the website without confirming his account.
# config.allow_unconfirmed_access_for = 2.days
# A period that the user is allowed to confirm their account before their
# token becomes invalid. For example, if set to 3.days, the user can confirm
# their account within 3 days after the mail was sent, but on the fourth day
# their account can't be confirmed with the token any more.
# Default is nil, meaning there is no restriction on how long a user can take
# before confirming their account.
# config.confirm_within = 3.days
# If true, requires any email changes to be confirmed (exactly the same way as
# initial account confirmation) to be applied. Requires additional unconfirmed_email
# db field (see migrations). Until confirmed new email is stored in
# unconfirmed email column, and copied to email column on successful confirmation.
config.reconfirmable = false
# Defines which key will be used when confirming an account
# config.confirmation_keys = [ :email ]
# ==> Configuration for :rememberable
# The time the user will be remembered without asking for credentials again.
# config.remember_for = 2.weeks
# If true, extends the user's remember period when remembered via cookie.
# config.extend_remember_period = false
# Options to be passed to the created cookie. For instance, you can set
# :secure => true in order to force SSL only cookies.
# config.rememberable_options = {}
# ==> Configuration for :validatable
# Range for password length. Default is 8..128.
config.password_length = 8..128
# Email regex used to validate email formats. It simply asserts that
# one (and only one) @ exists in the given string. This is mainly
# to give user feedback and not to assert the e-mail validity.
# config.email_regexp = /\A[^@]+@[^@]+\z/
# ==> Configuration for :timeoutable
# The time you want to timeout the user session without activity. After this
# time the user will be asked for credentials again. Default is 30 minutes.
# config.timeout_in = 30.minutes
# If true, expires auth token on session timeout.
# config.expire_auth_token_on_timeout = false
# ==> 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 = :both
# 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
# ==> Configuration for :recoverable
#
# Defines which key will be used when recovering the password for an account
# config.reset_password_keys = [ :email ]
# Time interval you can reset your password with a reset password key.
# Don't put a too small interval or your users won't have the time to
# change their passwords.
config.reset_password_within = 6.hours
# ==> Configuration for :encryptable
# Allow you to use another encryption algorithm besides bcrypt (default). You can use
# :sha1, :sha512 or encryptors from others authentication tools as :clearance_sha1,
# :authlogic_sha512 (then you should set stretches above to 20 for default behavior)
# and :restful_authentication_sha1 (then you should set stretches to 10, and copy
# REST_AUTH_SITE_KEY to pepper).
#
# Require the `devise-encryptable` gem when using anything other than bcrypt
# config.encryptor = :sha512
# ==> Configuration for :token_authenticatable
# Defines name of the authentication token params key
config.token_authentication_key = :auth_token
# ==> Scopes configuration
# Turn scoped views on. Before rendering "sessions/new", it will first check for
# "users/sessions/new". It's turned off by default because it's slower if you
# are using only default views.
config.scoped_views = false
# Configure the default scope given to Warden. By default it's the first
# devise role declared in your routes (usually :user).
# config.default_scope = :user
# Set this configuration to false if you want /users/sign_out to sign out
# only the current scope. By default, Devise signs out all scopes.
config.sign_out_all_scopes = false
# ==> Navigation configuration
# Lists the formats that should be treated as navigational. Formats like
# :html, should redirect to the sign in page when the user does not have
# access, but formats like :xml or :json, should return 401.
#
# If you have any extra navigational formats, like :iphone or :mobile, you
# should add them to the navigational formats lists.
#
# The "*/*" below is required to match Internet Explorer requests.
config.navigational_formats = ['*/*', :json, :html]
DeviseController.respond_to :html, :json
# The default HTTP method used to sign out a resource. Default is :delete.
config.sign_out_via = :delete
# ==> OmniAuth
# Add a new OmniAuth provider. Check the wiki for more information on setting
# up on your models and hooks.
# config.omniauth :github, 'APP_ID', 'APP_SECRET', :scope => 'user,public_repo'
# ==> Warden configuration
# If you want to use other strategies, that are not supported by Devise, or
# change the failure app, you can configure them inside the config.warden block.
#
config.warden do |manager|
manager.failure_app = ::FailureApp
end
# ==> Mountable engine configurations
# When using Devise inside an engine, let's call it `MyEngine`, and this engine
# is mountable, there are some extra configurations to be taken into account.
# The following options are available, assuming the engine is mounted as:
#
# mount MyEngine, at: '/my_engine'
#
# The router that invoked `devise_for`, in the example above, would be:
# config.router_name = :store
#
# When using omniauth, Devise cannot automatically set Omniauth path,
# so you need to do it manually. For the users scope, it would be:
# config.omniauth_path_prefix = '/my_engine/users/auth'
end
User.rb：
module Store
class User < DataModels::User
devise :confirmable, :rememberable, :async, :database_authenticatable, :registerable,
:recoverable, :validatable
validates :firstname,
:lastname,
presence: true,
allow_blank: false,
allow_nil: false
belongs_to :group, touch: true
belongs_to :shipping, class_name: "Address"
belongs_to :billing, class_name: "Address"
has_many :sales, as: :saleable
has_many :orders
# Rest removed for brevity
end
end
有什么指示？我整天都在谷歌上搜索和挖掘Devise和Warden的源代码，但无济于事。
答案 0 :(得分：2)
少数事情：
:async设计选项有什么作用？::FailureApp的来源是什么？你确定它实际上是Devise注销你，而不是ActiveAdmin没有授权你通过CanCan或你自己的自定义:authorization_adapter进行操作吗？似乎不太可能是断断续续的，但通过在ApplicationController中配置AA以使用您自己的方法可以很容易地检查，这样您就可以检查异常，当前用户以及发生时通过Pry的所有内容。
答案 1 :(得分：1)
我们从来没有弄清楚究竟是什么问题，但我猜测memcached因某种原因正在席卷会议。
我们切换到在数据库中存储会话，从那以后我们还没有看到这个问题。
