ruby-on-rails - 注销链接的路由问题？删除与获取操作？

Question

现在我的注销链接的路由指向 sessions#destroy，但它不是 HTTP 删除动词，所以它不起作用。这个问题让我很沮丧，因为我应该能够自己解决这个问题，但到目前为止我还没有运气。这是我在尝试注销时收到的错误消息:

没有路由匹配 [DELETE] "/logout"

这是我的路线文件:

Rails.application.routes.draw do



  get 'line_items/create'



  root 'static_pages#home'
  get 'testimonials' => 'static_pages#testimonials'
  get 'help' => 'static_pages#help'
  get 'about' => 'static_pages#about'
  get 'contact' => 'static_pages#contact'
  get 'signup' => 'users#new'
  get 'login' => 'sessions#new'
  get 'logout' => 'sessions#destroy'
  resources :users
  resources :sessions, only: [:new, :create, :destroy]
  resources :products
  resources :categories
  resources :line_items
  resources :carts
 end

session Controller 中的销毁方法:

def destroy
  forget(current_user)
  session.delete(:user_id)
  @current_user = nil
  redirect_to root_url
end

注销链接:

          <li>
            <%= link_to "Log out", logout_path, method: "delete" %>
          </li>

rake路由的相关结果:

logout_path     GET     /logout(.:format)   sessions#destroy
users_path  GET     /users(.:format)    users#index
POST    /users(.:format)    users#create
new_user_path   GET     /users/new(.:format)    users#new
edit_user_path  GET     /users/:id/edit(.:format)   users#edit
user_path   GET     /users/:id(.:format)    users#show
PATCH   /users/:id(.:format)    users#update
PUT     /users/:id(.:format)    users#update
DELETE  /users/:id(.:format)    users#destroy
sessions_path   POST    /sessions(.:format)     sessions#create
new_session_path    GET     /sessions/new(.:format)     sessions#new
session_path    DELETE  /sessions/:id(.:format)     sessions#destroy 

感谢您的帮助。

你有两个选择:

1. 更改链接以使用定义的路由

   <%= link_to "Log out", logout_path %>
   

   或

   <%= link_to "Log out", session_path, method: "delete" %>
   

   请注意，为了使最后一个链接起作用，您需要将其更改为单一资源(资源，而不是资源)。

   resource :sessions, only: [:new, :create, :destroy]
   

2. 改变路线从

   get 'logout' => 'sessions#destroy'
   

   到

   delete 'logout' => 'sessions#destroy'
   

无论如何，session 上的复数 resources 没有意义。
