如果一个人没有经过身份验证，我该怎么做才能将其转发到登录页面？我该如何破坏他们的会话，以便在他们注销时正确地转发到登录页面？
参考资料：用户设计：用户config/initalizer/develope.rb将
config.sign\u-out\u-via=：删除改为config.sign\u-via=：获取你做的一切都是对的。唯一缺少的是：method=>：delete
调用。这是特定于rails的，您需要rails ujs或较早版本的rails jquery_ujs才能使其工作
将此添加到您的app/assets/javascripts/application.js：
如果不添加此项，则method:：delete
调用将不起作用。如果您根本不想使用它，那么将“注销”更改为使用GET
更改或将其添加到您的config/initializers/designe.rb：
如果它仍然不工作，那么您的config/routes.rb文件中的顺序是错误的<代码>设计：用户
必须在资源：用户
之前：
devise_for :users
resources :users
你可以发布你的config/routes.rb
？显示你的路线。@m.simonborg routes.rb发布！对不起，谢谢！rake routes
的输出可能会有帮助，因为它会导致No route matches[GET]“/users/sign_out”
unfortunatelygotoconfig/initializer/designe.rb
和change-lineconfig.sign_-out\u via=：delete
到config.sign_-out\u via=：GET
No，它们没有冲突。您必须先使用design_:users
，然后再使用resources:users
。我在不同的应用程序上使用ruby 2.4.x和2.5.x以及rails 4.2.x到5.1.5。如果您使用webpacker进行资产编译，那么rails 5.1+就是这样，否则，jquery\u ujs
方法仍然是一条路要走。对我来说，我需要这样做，我没有使用注销/via=：get
，但我必须确保我的设计注销链接包括方法：：delete
ala=链接到（'Logout'，destroy\u user\u session\u path，class:'nav\u link'，方法：：delete）
