root_path get方法的Rails问题

Question

感谢您的专家建议。如果这个问题不合适或者不合适，请发表评论或邮寄给我，我会将其删除。

我正在构建一个使用两个不同布局的Ruby on Rails应用程序。第一页是设置为应用程序根目录的介绍页面，新用户可以在其中显示有关应用程序的一些基本信息，然后登录或注册。

第一页有完美的布局 main.html.erb 和视图 main / welcome.html.erb

当用户单击“注册”链接时，将调用“注册”的设计视图。

<%= link_to "Sign Up", new_account_registration_path  %>

由于Application Controller具有第二个用户布局，它会毫无问题地显示此布局中的所有视图。

class ApplicationController < ActionController::Base
    layout "user"

    protect_from_forgery with: :exception
end

在视图 registration / new 中，我有另一个链接，允许用户取消注册并返回应用程序的主页和根目录（呈现布局 main.html.erb 和视图 main / welcome.html.erb ）。

如果我使用方法的根路径:: get ，根页面将加载而不会有任何问题。 布局和视图都会加载。

<%= link_to "Cancel", root_path, method: :get, :class => "btn btn-default wideButton" %>

如果我在没有get方法的情况下使用root_path，则不会加载某些内容。 这是结果：

this case

首页将加载，但仅限于导航栏，而其他HTML内容将无法加载。

在我使用的情况下：method =＆gt; ：get，页面有效，这就是结果。 主要区别在于，在第一种情况下（不工作）有一个get请求，而在第二种情况下（页面加载）浏览器显示一个发送请求到/.

这是非工作方案的日志。另外我会问在这种不调用cancel_account_registration_path的情况下有什么风险。

非常感谢。 最好的祝福 Fabrizio Bertoglio
