在设计中的sign_in动作的不同布局 [英] different layout for sign_in action in devise

问题描述

我正在尝试使用名为devise的不同/自定义布局作为sign_in操作。我在设计维基中发现了这个页面，第二个例子甚至表示你可以按照每个动作（在这种情况下， sign_in 操作）来执行，但是它没有显示这样的例子。 IRC上有人告诉我可以试试这个：

  class ApplicationController< ActionController :: Base 
 protect_from_forgery 
 
布局：layout_by_resource 
 
 def layout_by_resource 
如果devise_controller？ &安培;&安培; resource_name ==：user&& action_name =='sign_in'
devise
 else 
应用程序
 end 
 end 
 end 
  

但它似乎没有工作，因为它仍然加载默认的应用程序布局。我会感谢任何帮助。

解决方案

我想出来，但我会在这里保留这个问题，以防其他人好奇

这是一个愚蠢的错误。事实是 sign_in 是路径，不是的动作。查看相关来源，我可以看到所需的操作是 new ，即创建一个新的设计会话。更改我的上述代码条件为：

  if devise_controller？ &安培;&安培; resource_name ==：user&& action_name =='new'
  

精美地工作。

希望有帮助的人在那里。

I'm trying to use a different/custom layout named "devise" for the sign_in action. I found this page in the devise wiki, and the second example even says you can do it per-action (in this case, sign_in action), but it shows no example of doing that. Someone on IRC told me I could try this:

class ApplicationController < ActionController::Base
  protect_from_forgery

  layout :layout_by_resource

  def layout_by_resource
    if devise_controller? && resource_name == :user && action_name == 'sign_in'
      "devise"
    else
      "application"
    end
  end
end

But it does not seem to be working as it's still loading the default application layout. I would appreciate any help.

解决方案

I figured it out, but I'll keep this question here in case other people are curious.

It was a stupid mistake. The fact is sign_in is the path, not the action. Looking at the relevant source, I can see that the required action is new, i.e., creating a new Devise Session. Changing my above code's conditional to:

if devise_controller? && resource_name == :user && action_name == 'new'

Works beautifully.

Hope that helps someone out there.
