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

问题描述

我正在尝试为 sign_in 操作使用名为devise"的不同/自定义布局.我在设计 wiki 中找到了 this 页面，并且第二个示例甚至说您可以按操作执行此操作(在本例中为 sign_in 操作)，但没有显示执行此操作的示例.IRC 上有人告诉我我可以试试这个:

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

但它似乎不起作用，因为它仍在加载默认的应用程序布局.我将不胜感激.

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

推荐答案

我想通了，但我会把这个问题留在这里以防其他人好奇.

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

这是一个愚蠢的错误.事实上，sign_in 是路径，不是动作.查看相关源码，可以看到所需的操作是new，即创建一个new设计会话.将我上面代码的条件更改为:

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'

效果很好.

希望能帮助到那里的人.

Hope that helps someone out there.
