Rails current_page？与controller.controller_name [英] Rails current_page? versus controller.controller_name

问题描述

我在一个视图中实现 current_page？，以测试当前控制器和操作是否等于某个值，但它不会返回true控制器/操作组合。

   - 如果current_page？（：controller =>'pages'，：action =>'main '）
＃在控制器/操作组合上不返回true 
  

方法它是工作是如果我使用一个更详细的方法像这样：

   - 如果controller.controller_name ==' && controller.action_name =='main'
＃这个工作很好
  

或者还有别的事情发生在这里？有没有更好的方法这样做，如设置BOOL或这是正确的方式？

最终目标是只显示一个特定的标题在主登陆页面，而在所有其他页面上显示不同的标题。

编辑： rake路线的相关输出：

  pages_main GET /pages/main(.:format）{：controller =>pages，：action =>main} 
 
 root /(.:format）{：controller =>pages，：action =>main} 
  

此外，这是渲染时的服务器输出：

  127.0.0.1 at 2011-03-03 16:54:40 -0500 
由PagesController处理＃main作为HTML 
在布局/应用程序（203.6ms）内渲染的页面/ main.html.haml 
  

解决方案

current_page？（root_path）工作正常。

但我不能使用：controller 和：action

看起来帮助者需要一个字符串，因此：

  current_page？（url_for（：controller =>'pages'，：action =>'main'））
   
 
 
与文档。
 
I'm implementing current_page? in a view to test if the current controller and action is equal to a certain value, however it won't return true when on that controller/action combination.
- if current_page?(:controller => 'pages', :action => 'main') 
# doesn't return true when on that controller/action combination
The only way it is working is if I use a bit more verbose method like so:
- if controller.controller_name == 'pages' && controller.action_name == 'main'
# this works just fine
Is my syntax wrong or is there something else happening here?  Is there a better way of doing this, such as setting a BOOL or is this the proper way?

The end goal is to only show a certain header on the main landing page while showing a different header on all other pages.  

Edit: Relevant output from rake routes:
pages_main GET  /pages/main(.:format)  {:controller=>"pages", :action=>"main"}

root   /(.:format)   {:controller=>"pages", :action=>"main"}
Also, this is the server output upon rendering:
Started GET "/" for 127.0.0.1 at 2011-03-03 16:54:40 -0500
Processing by PagesController#main as HTML
Rendered pages/main.html.haml within layouts/application (203.8ms)

解决方案
current_page?(root_path) works fine.

But I can't make it work with :controller and :action

It seems the helper expects a string, so:
current_page?(url_for(:controller => 'pages', :action => 'main')) 
works fine too.

Weird contradiction with the doc.
