How to devise destroy session and sign out from controller?
提问by fabbb
Devise destroy session and sign out from controller?
设计销毁会话并从控制器注销？
if something_is_not_kosher
# 1. log this event, 2. send notice
redirect_to destroy_user_session_path and return
end
Also tried:
还试过：
if something_is_not_kosher
# 1. log this event, 2. send notice
redirect_to controller: 'devise/sessions', action: 'destroy', method: :delete and return
end
Error is No route matches [GET] "/users/sign_out"but I'm explicitly setting method: :delete in example 2. Maybe devise has a method? current_user.sign_outand tried sign_out(current_user) which also don't work? Thanks for the help.
错误是，No route matches [GET] "/users/sign_out"但我在示例 2 中明确设置了方法：:delete。也许设计有一个方法？current_user.sign_out并尝试了 sign_out(current_user) 这也不起作用？谢谢您的帮助。
rake routes:
耙路线：
new_user_session GET /users/sign_in(.:format) devise/sessions#new
user_session POST /users/sign_in(.:format) devise/sessions#create
destroy_user_session DELETE /users/sign_out(.:format) devise/sessions#destroy
user_password POST /users/password(.:format) devise/passwords#create
new_user_password GET /users/password/new(.:format) devise/passwords#new
edit_user_password GET /users/password/edit(.:format) devise/passwords#edit
PATCH /users/password(.:format) devise/passwords#update
PUT /users/password(.:format) devise/passwords#update
cancel_user_registration GET /users/cancel(.:format) users/registrations#cancel
user_registration POST /users(.:format) users/registrations#create
new_user_registration GET /users/sign_up(.:format) users/registrations#new
edit_user_registration GET /users/edit(.:format) users/registrations#edit
PATCH /users(.:format) users/registrations#update
PUT /users(.:format) users/registrations#update
DELETE /users(.:format) users/registrations#destroy

So I ended up solving this by creating a custom signout route
所以我最终通过创建自定义注销路由来解决这个问题
devise_scope :user do
get '/signout', to: 'devise/sessions#destroy', as: :signout
end
and in my controller I have:
在我的控制器中，我有：
if something_is_not_kosher
redirect_to signout_path and return
end

Why don't you just use devise's built-in sign_out_and_redirect(current_user)method?
为什么不直接使用 devise 的内置sign_out_and_redirect(current_user)方法？

destroy_user_session_path(@user)is sign out path for user, but it must requst with DELETEmethod. redirect_tomethod will tell broswer to request another path, but broswer just can request with GETmethod.
So if you want to let user to sign out, you must set a sign out form with DELETEmethod or with AJAX request to let user sign out but not with redirect_tofunction.
destroy_user_session_path(@user)是用户的退出路径，但必须使用DELETE方法。redirect_to方法会告诉浏览器请求另一条路径，但浏览器只能用GET方法请求。
所以如果你想让用户退出，你必须设置一个带有DELETE方法或AJAX请求的退出表单，让用户退出而不是redirect_to功能。
If you just want to destroy user session, use sign_out @useris ok.
如果你只是想销毁用户会话，使用sign_out @user是可以的。

Just in case someone can't use it directly.
以防万一有人不能直接使用它。
<% if user_signed_in? %>
<li><%= link_to "Logout", destroy_user_session_path, :method => :delete %></li>
<% else %>
<li><%= link_to "Sign up now!", new_user_registration_path%></li>
<% end %>
