content_for不在部分视图中呈现-content_forarenotrenderinginpartialviews

I have a rails app which uses a layout

我有一个使用布局的rails应用程序

The simplified version looks like this:

简化版本如下所示:

  
    <%= render 'layouts/head' # renders the "layouts/_head.html.erb" partial correctly  
                              # the most head (css/js) content gets implemented here %>
  
  

    <%= yield # renders the current action %>

    
    <%= content_for :scripts_bottom %>
  

in my `layouts/_head.html.erb' I use

在我的'layouts / _head.html.erb'我用

 <%= content_for :scripts_head %>
 

In my partials I place the following snippets to append them :scripts_head. (some of my partials should put Javascripts

在我的部分内容中,我将以下片段附加到它们:scripts_head。 (我的部分内容应该放在Javascripts中

<% content_for :scripts_head do %>
    <%= Javascript_include_tag 'some_script' %>
<% end %>

The content_for in the `layouts/head' renders nothing

`layouts / head'中的content_for没有任何内容

How can I resolve that?

我怎么解决这个问题?

It looks like that partials are not able to append their content_for content when the content_for :blah do is placed BEHIND the echoing content_for / yield tag.

当content_for:blah do放置在echoing content_for / yield标记之后,看起来部分无法附加其content_for内容。

If I try try content_for :scripts_bottom it will get rendered at the bottom of the page.

如果我尝试尝试content_for:scripts_bottom,它将在页面底部呈现。

Thanks in advance
