生产中找不到轨道4资产（摘要路径正常）

Question

我在生产中遇到资产问题。

我无法加载样式表，JavaScript或甚至图像。

当我尝试访问某些内容时，它显示我错误 - 未找到 但是当我尝试使用-digest访问时，没关系。

我有资产预编译，通过Capistrano的成功部署清单 - > assets_manifest.json

感谢

日志：样式错误（样式表加载themes_for_rails宝石） 当我试图进入/资产/默认/stylesheets/application-ec9a310f792c60f2f77810cfcd9b903f.css，就是一切OK

Answer 1

我有一个类似的问题，以你的。

这里是我的IMAGE_TAG链接的解决方案：使用IMAGE_TAG asset_path（）代替IMAGE_TAG“/pic.ext”是这样的：

<%= image_tag asset_path("combat_elephant.png") %> 
<%= link_to (image_tag asset_path("puskay_pivka_zahvatyat.png")), "/path" %> 

而且我使用nginx的的静态资产，所以我必须配置.serve_static_assets =虚假和config.assets.compile =真

希望帮助

这里描述你可能有同样的问题：No route matches [GET] /assets

基本上，如果您使用Rails服务器来测试您的应用程序，则预编译的资产不会在默认情况下提供。 Rails期望Web服务器（apache，nginx等）为它们提供服务。您需要更改config/environments/production.rb并将serve_static_assets设置为true。
