如何转到rails中的注销路径？

Question

我使用的是 Rails 7，当我单击注销时，它显示一条错误，指出未找到注销路径。 这是我的routes.rb、会话控制器和注销标头部分的代码：

Rails.application.routes.draw do
  # Define your application routes per the DSL in https://guides.rubyonrails.org/routing.html

  # Defines the root path route ("/")
  root 'pages#home'
  get 'about', to: 'pages#about'
  resources :articles
  get "/signup", to: "users#new"
  resources :users, except: [:new]
  get "/login", to: "sessions#new"
  post "/login", to: "sessions#create"
  delete '/logout', to: 'sessions#destroy'

end




<li class="nav-item">
            <%= link_to "Log out", logout_path, method: :delete, class: "nav-link" %>
   </li>



 def destroy
    session[:user_id] = nil
    flash[:notice] = "Logged out"
    redirect_to root_path

  end

Answer 1

您的链接正在发送 GET 请求，但它应该是 DELETE。这是因为 Rails 7 默认带有 Turbo。尝试：

<%= link_to "Log out", logout_path, data: {turbo_method: :delete} %>

Answer 2

使用

button_to

而不是

link_to

。这将创建一个实际的表单元素，而不是依赖 JavaScript。

<%= button_to "Log out", 
              logout_path, 
              method: :delete, 
              class: "nav-link" %>

如果您出于某种原因实际上需要一个发送非 GET 请求的链接，那么 Turbo 会将其事件处理程序附加到

data-turbo-method

，而不是 Rails UJS 使用的

data-method

：

<%= link_to "Log out", 
             logout_path, 
             data: { turbo_method: :delete }, 
             class: "nav-link" %>
