我试图使用Ruby on Rails切换布局,但我得到错误:#的未定义方法`layout'.我正在使用Rails 2.3.5我错过了一个包含？

这是代码:

class HelloController < ApplicationController

  def index

    layout 'standard'
    @message = "Goodbye!"
    @count = 3
    @bonus = "This is the bonus message!"
  end

end

我在MacOS上使用MonoDevelop,我很难在Google Chrome上看到AjaxControlToolkit的TabContainer.我甚至将TabContainer和TabPanels的visible属性设置为true,但它仍然无效.这是源HTML:

<ajaxToolkit:ToolkitScriptManager  id="tsm1" runat="server" />

    <div style="position:absolute;top:0px;left:0px;">
       <img src="" />
    </div>
    <div style="position:absolute;top:200px;left:20px;">
    <ajaxToolkit:TabContainer id="NewTabContainer" runat="server" Height="300px" Visible="true" >
        <ajaxToolkit:TabPanel id="FirstPanel" runat="server" HeaderText="Tab 1" Visible="true" >
            <ContentTemplate>
                PAGE ONE - This is the first Panel.
            </ContentTemplate>
        </ajaxToolkit:TabPanel>
        <ajaxToolkit:TabPanel id="SecondPanel" runat="server" HeaderText="Tab 2" Visible="true" >
            <ContentTemplate>
                PAGE TWO - This is the second Panel.
            </ContentTemplate>
        </ajaxToolkit:TabPanel>
     </ajaxToolkit:TabContainer>

这是HTML Chrome生成的内容:

<div id="NewTabContainer" class="ajax__tab_xp" style="visibility:hidden;">
    <div id="NewTabContainer_header">
        <span id="NewTabContainer_FirstPanel_tab"><span class="ajax__tab_outer"><span class="ajax__tab_inner"><span class="ajax__tab_tab" id="__tab_NewTabContainer_FirstPanel">Tab 1</span></span></span></span><span id="NewTabContainer_SecondPanel_tab"><span class="ajax__tab_outer"><span class="ajax__tab_inner"><span class="ajax__tab_tab" id="__tab_NewTabContainer_SecondPanel">Tab 2</span></span></span></span>
    </div><div id="NewTabContainer_body" …

我正在尝试使用NAnt构建Mono项目,但我收到下面列出的错误.我已经尝试更改环境变量PKG_CONFIG_PATH以包含通向该文件的路径:mono.pc但似乎不起作用.
