更新:请随意给我反对票,因为问题是我将文件命名为 _stylesheet.html.erb 而不是 _stylesheets.html.erb。我以为我检查了拼写,但显然我没有。对于浪费大家的时间,我深表歉意,我感谢您的意见。

你好,

我正在学习 Rails,我从Michael Hartl 的 Ruby on Rails 教程 - 通过示例学习 Rails开始。他慷慨地把这本书放到了网上。我目前在部分部分,我看到一个奇怪的问题,自昨晚以来我一直在尝试解决。我按照部分部分中的说明进行操作,但出现以下错误:

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">

对我来说有趣的是,我在本地还有其他项目可以成功渲染局部。所以我知道这不是 rails 版本问题(另一个有效的项目没有冻结 rails)。我还检查了我的部分是否在 app/views/layouts 中,并且它们的名称前有一个下划线,并且它们的扩展名的顺序正确(.html.erb)。

这是控制器:

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能老实说。非常感谢您对此事的任何帮助。

谢谢!

阿什什

我真的不知道您使用的是什么 Rails 版本,但我建议使用以下方法之一:

  1. 添加 :partial 选项:(<%= render :partial=>'layouts/stylesheets' %>我相信这个对你有用)
  2. 将文件 stylesheets.html.erb 重命名为 stylesheets.erb(我对这个不太满意,但它可能对你有用)。

由于您正在尝试渲染部分文件,您的部分文件是否带有下划线前缀?

_stylesheets.html.erb
