兩個content_for所有視圖中的相同良率呈現（Rails 3）

Question

我有兩個單獨的視圖，它們正在輸出名爲：icons的命名yield塊的內容。

當我打開兩個頁面，我總是看到：圖標塊2個視圖的內容... :-(

視圖1：項目＃指數

<% content_for :icons do %> 
    Project Icons ... 
<% end %> 
... 

查看2 ：樹＃顯示

<% content_for :icons do %> 
    <a href="javascript:void(0)" id="dynatree-expand-all">Expand</a> 
    <a href="javascript:void(0)" id="dynatree-collapse-all">Collapse</a> 
    <a href="javascript:void(0)" id="dynatree-transfer">Import</a> 

    <div id="viewname_selector"> 
    <%= form_tag({:controller => :loopview, :action => :show}, { :id => "viewname_form" ,:remote => true}) do %> 
     <%= collection_select(:viewname, :id, @viewnames, :id, :name, :selected => @current_viewname_id) %> 
    <% end %> 
    </div> 
<% end %> 

而且在application.html.erb呼叫

<div id="icons"> 
    <%= yield :icons %> 
</div> 

當我加載項目＃索引，我只有項目圖標（所以它沒事）。

當我加載樹＃指數，我有樹圖標和項目圖標...

我到底做錯了什麼？如何只在樹視圖中獲取樹圖標？

編輯：樹＃指數的完整源

<% content_for :head do %>

<div id='dynatree-title' data-project-id='<%= current_project.id %>'> 
    <span></span><%= current_project.name %>

<!-- Leftpanel Dynatree --> 
<%= render_project_tree(current_project, "tree") %> 

<!-- Leftpanel "New Child" Form --> 
<%= render :partial => "lean_new_child" %>

<!-- Right Panel --> 
<div id="dynatree-details"> 
    <%= render :template => 'projects/show' %> 
</div> 

Answer 1

我可以知道你爲什麼要添加下面的代碼application.html.erb。

<div id="icons"> 
    <%= yield :icons %> 
</div> 

我認爲這只是裝載在您的Tree#index頁面太..
