和我的application_controller

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如果您绝对需要使用链接，则应使用
data: { turbo_method: :delete }method: :delete<%= 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
