当我登录我的应用时，它说我已成功登录。但是当我点击导航栏中的链接退出时，它会给我一个路由错误。
我不确定为什么我一直收到路由错误。我已经基本上尝试了所有关于此错误的答案，但我似乎无法弄明白。

# :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.

# 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.

# 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 = [:database]` will
# enable it only for database authentication. The supported strategies are:
# :database = Support basic authentication with authentication key + password

# By default Devise will store the user in session. You can skip storage for
# particular strategies by setting this option.

# 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. Note that, for bcrypt (the default
# encryptor), the cost increases exponentially with the number of stretches (e.g.
# a value of 20 is already extremely slow: approx. 60 seconds for 1 calculation).
config.stretches = Rails.env.test? ? 1 : 10
# Setup a pepper to generate the encrypted password.

# ==> Configuration for :confirmable
# A period that the user is allowed to access the website even without
# confirming their account. For instance, if set to 2.days, the user will be

# access will be blocked just in the third day. Default is 0.days, meaning
# the user cannot access the website without confirming their 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 = true
# 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.

# secure: true in order to force SSL only cookies.

# ==> Configuration for :validatable
# Range for password length.
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
# Warn on the last attempt before the account is locked.
# config.last_attempt_warning = true
# ==> 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
# ==> 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 = true
# ==> 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 = ['*/*', :html]
# 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.intercept_401 = false
# manager.default_strategies(scope: :user).unshift :some_external_strategy
# 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 = :my_engine
#
# 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
class User < ActiveRecord::Base
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
end
application_controller.rb
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
end

resources :plugs
devise_for :users
root 'pages#home'
get 'about' => 'pages#about'
get 'contact' => 'pages#contact'
devise_scope :user do
get 'users/sign_out' => "devise/sessions#destroy"

上面的代码是否正确设置了语法？
答案 0 :(得分：5)
尝试以下
将以下代码粘贴到routes.rb
中devise_scope :user do
get 'users/sign_out' => "devise/sessions#destroy"
end
答案 1 :(得分：1)
试试这个：
1.在_header.html.erb
替换
<li><%= link_to "Sign out", destroy_user_session_path, :method =>
> 'delete' %></li>
到
<li><%= link_to "Sign out", destroy_user_session_path, :method => :get
> %></li>
2.In devise.rb
替换
config.sign_out_via = :delete
到
config.sign_out_via = :get
