ruby-on-rails – 访问rails资产的相对路径

前端之家收集整理的这篇文章主要介绍了ruby-on-rails – 访问rails资产的相对路径前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我被卡住了! xD我一直在研究Rails项目,但是在使用相对路径访问我的资产时遇到了问题.当我处理控制器和模型时,我的一个朋友正在研究html / css方面的事情.我的朋友最近给了我一批以下列方式构建的文件
app/assets/images/*.jpg
app/assets/stylesheets/*.css
app/assets/javascripts/*.js
app/assets/fonts/*.* (+some more css files in here)

在我的app / views / layouts目录中,我有一个名为final.html.erb的布局,用于我的整个webapp.我还有1页(html正文内容),我正在尝试使用名为final_page.html.erb的app / views / pages中的此布局进行渲染…必要的路由到位才能加载页面;但是,它只加载final_page.html.erb的上下文(没有图像,样式或字体).当我进入控制台并键入“rails server”并访问localhost:3000时,页面显示…裸体lol.控制台输出以下内容

我认为问题是我正在尝试使用相对路径访问文件.我的布局文件如下所示:

<!doctype html>
<html class="no-js">
<head>
<Meta charset="utf-8">
<Meta name="viewport" content="width=device-width,initial-scale=1">
<Meta name="viewport" content="width=device-width">
<title>:: Final ::</title>
<link rel="stylesheet" type="text/css" href="../../assets/stylesheets/style.css">
<link href="../../assets/stylesheets/desktop.css" rel="stylesheet" type="text/css" media="only screen and (min-width:769px) and (max-width:1000px)">
<script src="../../assets/javascripts/modernizr.js" type="text/javascript"></script>
</head>
<body>
  <%= yield %>
</body>
</html>

另外,在我的final_page.html.erb文件的正文中,我尝试使用相对路径访问图像……就像这样:

<img src="../../assets/images/mainImg.jpg" alt="img">

我的朋友写了大部分这个HTML,他有使用rails的经验.我决定更改资产请求,如下所示:

从:

<link rel="stylesheet" type="text/css" href="../../assets/stylesheets/style.css">

至:

<%= stylesheet_link_tag "application.css" %>

从:

<script src="../../assets/javascripts/modernizr.js" type="text/javascript"></script>

至:

<%= javascript_include_tag "application.js" %>

从:

<img src="../../assets/images/mainImg.jpg" alt="img">

至:

<%= image_tag "mainImg.jpg"  %>

这有点帮助,因为图像加载,并且很少有造型通过;然而,它远离它应该看起来的样子.我在想它是因为我的朋友在css文件中自己进行相对调用

body {
    background-image: url(../images/bg.jpg);
    background-repeat: repeat;
}

我尝试用url替换它们(<%= asset_path'bg.jpg'%>)等等……
但它没有效果.我已经尝试了很多东西,并且阅读了很多帖子.我想知道Rails是否允许我使用相对路径.我试过了:

config.assets.enabled = false

但这没有帮助……拜托……我做错了什么?我不认为我的朋友会想要停止使用相对路径来完成他的工作,因为这是他做事的方式.该网站在Rails之外启动很好,但我需要它与Rails一起使用我的webapp.任何建议将不胜感激.感谢您耐心阅读所有这些内容.

附:我正在使用Ruby 1.9.3和Rails 3.2.6

解决方法

尝试使用/assets/style.css而不是/assets/stylesheets/style.css等.

如果有这样的结构:

app
  assets
    stylesheets
    javascripts

然后,要访问app / assets或app / assets / any_folder中的文件,您应该使用path / assets / file.

更新

在这里尝试:

body {
    background-image: url(bg.jpg);
    background-repeat: repeat;
}

要么:

body {
    background-image: url(/assets/bg.jpg);
    background-repeat: repeat;
}
