Rails 4.1图像url仍在调用未编译的资产 [英] Rails 4.1 image url's still calling uncompiled assets

问题描述

所以我有大量的生产轨道网站，但我意识到我失踪了一些图像。我看着我的预编译css文件，图像url直接调用图像直接像 url（/assets/gototop.png）它不会找到，因为我的图像现在例如 gototop-6c119f88349ddd550e3efcf5bbefe1ad.png 。

So I have got my rails site up on production for the most part but I realized I was missing a few images. I looked at my precompiled css file and the image url's are calling the images directly like url(/assets/gototop.png) which it won't find since my image is now something like gototop-6c119f88349ddd550e3efcf5bbefe1ad.png.

如何让我的css指向预编译的图片文件？

How do I get my css to point to the precompiled image file?

更新：链接文件我意识到我可以使用asset_path方法，但不幸的是，我使用scss，我不能只是添加.erb到文件的末尾...似乎rails不喜欢使用多个编译器。 （我试过）

Update: also as stated in the linked file I realize I could use the asset_path method but unfortunately I am using scss and I can't just add .erb to the end of the file...seems rails doesnt like to work with multiple compilers. (I tried)

推荐答案

这是由资产指纹（不仅仅是Rails 4.1问题）

This is a common problem caused by asset fingerprinting (not just a Rails 4.1 issue)

修复它的方法是在CSS中使用预编译器（Rails自带 SASS ）。预编译器基本上意味着你可以处理CSS文件，如 erb - 使用某些助手&变量：

The way to fix it is to use a precompiler in your CSS (Rails comes with SASS). A precompiler basically means you can treat CSS files like erb -- use certain helpers & variables:

#app/assets/stylesheets/application.css.sass
body
  background: asset_url("/layout/gototop.png")

---

asset_url （似乎现在称为 asset-url ）基本上允许您通过指纹名称调用资产

---

asset_url (seems it's now called asset-url) basically allows you to call assets by their fingerprinted name

我们的讨论，你还需要用 rake assets：precompile RAILS_ENV = production 来做到这一点。在控制台中触发此命令后，它按预期工作

As per our discussion, you also need to do this with rake assets:precompile RAILS_ENV=production. After firing this command in the console, it worked as expected
