和我的application_controller

class ApplicationController < ActionController::Base
  # Only allow modern browsers supporting webp images, web push, badges, import maps, CSS nesting, and CSS :has.
  allow_browser versions: :modern
end

我创建了一个新文件，创建了一个文件注册.rb，在其中放入了一些有关注销的代码

class SessionsController < ApplicationController
  def destroy
    reset_session
    redirect_to root_path, notice: 'Logged out successfully.'
  end
end

并且没有任何改变，比如删除方法不在其中或类似的东西

虽然您可以在这里逃避并只让链接发送 GET 请求，但这实际上不是一个好的解决方案，因为 GET 请求应该是幂等的并且存储在浏览器历史记录中。

更好的选择是定义正确的路线：

delete '/users/sign_out', as: :destroy_user_session       

并使用

button_to

：

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

button_to

创建一个实际的表单，即使没有 JavaScript 也可以工作，这是强化应用程序的关键功能以防止损坏的好方法。

如果您绝对需要使用链接，则应使用

data: { turbo_method: :delete }

而不是

method: :delete

，因为 Rails Unobtrusive JavaScript 驱动程序 (UJS) 在 Rails 7 中已作为默认值删除，并且 现在建议使用 Turbo 。

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

Turbo 提供了旧功能的替代品，但关键区别在于数据属性是“命名空间”的，因此它为具有

data-turbo-method

属性的链接添加了一个事件处理程序。
