我在生产中遇到资产问题。
我无法加载样式表，javascripts甚至图像。
当我尝试访问某些内容时，它会显示错误 - 未找到但是当我尝试使用-digest访问时，它没问题。
我有资产预编译，通过capistrano成功部署manifest - > assets_manifest.json
谢谢
日志：样式表错误（样式表加载了themes_for_rails gem）当我尝试访问/assets/default/stylesheets/application-ec9a310f792c60f2f77810cfcd9b903f.css时，一切正常

您可能遇到与此处描述的问题相同的问题： 没有路由匹配[GET] /资产
基本上，如果您使用rails服务器测试您的应用程序，默认情况下您的预编译资产将不会被提供。 Rails期望Web服务器（apache，nginx等）为它们提供服务。 您需要对config / environments / production.rb进行更改并将serve_static_assets设置为true。
我遇到了类似的问题。
这是我对image_tag链接的解决方案：使用image_tag asset_path（）而不是image_tag'/pic.ext'，如下所示：
<%= image_tag asset_path("combat_elephant.png") %>
<%= link_to (image_tag asset_path("puskay_pivka_zahvatyat.png")), "/path" %>
我也使用nginx来提供静态资产，所以我有config.serve_static_assets = false和config.assets.compile = true
希望有所帮助
