问题描述：

UPDATE：随意给我投了反对票，因为这个问题是我当时命名的文件_stylesheet.html.erb &不_stylesheets.html。 ERB。我以为我检查拼写，但很明显我没有。我很抱歉浪费大家的时间，我感谢你的意见。问题渲染*非常*简单部分在* *非常简单的应用程序

嗨，

我学习轨和我开始Ruby on Rails Tutorial - Learn Rails by Example by Michael Hartl。这是一本他正在慷慨地上网的书。我目前在partials section，我看到一个奇怪的问题，我昨天一直试图解决。我按照谐音部分的说明，但我收到以下错误：

ActionView::MissingTemplate in Pages#home 

Showing app/views/layouts/application.html.erb where line #6 raised: 

Missing layout layouts/_stylesheets.erb in view path app/views 
Extracted source (around line #6): 

3: <html lang="en" xml:lang="en" xmlns="http://www.w3.org/1999/xhtml"> 
4: <head> 
5:  <title><%= title %></title> 
6:  <%= render 'layouts/stylesheets' %> 
7: </head> 
8: <body> 
9:  <div class="container">

什么让我感兴趣的是，我有本地的其他项目，成功地使谐音。所以我知道这不是一个rails版本问题（另一个工程没有冻结rails）。我也检查过我的部分是在app/views/layouts中，并且在他们的名字和扩展名正确顺序（.html.erb）之前有一个下划线。

这里是控制器：

class PagesController < ApplicationController 
    def home 
    @title = "Home" 
    end 

    def contact 
    @title = "Contact" 
    end 

    def about 
    @title = "About" 
    end 

    def help 
    @title = "Help" 
    end 
end

这是非常标准的东西，我不知道为什么它不工作是诚实的。对此事的任何帮助都非常感谢。

谢谢！

阿希什

既然你想渲染一个部分，你的部分文件是否带有下划线的前缀？

_stylesheets.html.erb

@nowk - 是的。我检查了第一个。我的部分名为_stylesheets.html.erb，它位于app/views/layouts中。 – tundal45 2010-01-01 18:14:18

嗯，只是为了覆盖所有的基地，你有没有尝试重新启动你的应用程序？我最近在开发环境时遇到了一些问题，在2.3.5中没有重新启动的情况下没有处理新的东西。 – nowk 2010-01-01 18:32:09

@nowk - 我很抱歉没有提到这之前，但我试过重新启动服务器。我甚至重新启动了我的电脑（窗口坏习惯），但没有成功。 – tundal45 2010-01-01 19:04:29

我真的不知道什么Rails的你正在使用的版本，但我建议下列之一：

  1. 添加：部分选项：<%= render :partial=>'layouts/stylesheets' %>（我相信这一个会为工作你）
  2. 将文件stylesheets.html.erb重命名为stylesheets.erb（我对这个不是很满意，但它可能适用于你）。

我觉得他使用的是2.3.5版本。看看他的日志。我认为：部分=>'布局/样式表'你提到的事情会为这个人做伎俩。 – DJTripleThreat 2010-01-01 17:49:55

+0

@khelll - 感谢您的快速回复。我没有提到我曾尝试过显式：partial =>调用，但没有取得太大的成功。我也尝试将文件重命名为stylesheets.erb而不是stylesheets.html.erb，并且这种方式也不起作用。第二个不能正常工作，因为这违反了导轨和其他可用的文件。 @DJTripleThreat正确。我正在使用rails 2.3.5版，并且正在运行ruby 1.8.7（2009-06-12 patchlevel 174）。我可以提供哪些额外的信息可能指出为什么会发生这种情况？ – tundal45 2010-01-01 18:03:51

+0

@khell＆@DJTripleThreat：我很抱歉浪费你的时间。我意识到我已经命名文件_stylesheet.html.erb＆not _stylesheets.html.erb。菜鸟，我知道！ – tundal45 2010-01-01 19:28:57
