那些遇到过的问题

Rails 3.2.2在使用capistrano部署后在样式表和js资产上获得404

Daz*_*win 2 ruby-on-rails nginx unicorn ruby-on-rails-3.2 ubuntu-12.04

用这个把我的头发拉出来之后,我恐怕不得不再把那些更明智的知识转过来了.....

好的,这就是问题,我正在关注以下两个railscast:

在生产中部署到vps
资产管道

我的设置:
Ubuntu Server 12.04
nginx
unicorn
ruby 1.9.3p125
rails 3.2.2

据我所知,一切都被T(或茶或者也许是Tee,我从未见过这句话写过).现在,sit正在我的服务器上运行,但未加载样式表和javascript文件.它似乎与Rails 3.1 404相同的问题在加载公共/资产中存在的.css文件或样式表或JavaScript文件的Rails 404错误时出错.虽然第一个没有答案,但后者表明,Web服务器可能不会寻找静态资源,也许不应该这样做.

有人知道是什么原因引起的吗？

一些事实:

  • 首先,我得到了一些关于预编译的令人讨厌的错误,并注意到我的个人css/js文件已经缩小为他们的应用程序对应物,因此我在ruby助手中更改了他们的声明以反映这一点.

  • 当我改为config.serve_static_assets = truein 时,应用程序在本地工作config/environments/production.rb

  • 这是我的服务器上的生产.log的转储

正如您所看到的,不再有关于预编译的投诉

这是生成的html

如果nginx没有提供静态资产,那可能是由于root指令中的拼写错误.三重检查它是否正确引用rails公用文件夹.

在我的情况下,我忘记了我将我的应用程序移动到其他位置.这并没有完全破坏应用程序,因为nginx仍然可以通过我没有移动的独角兽套接字proxy_pass请求.

如果您从rails应用程序获得响应,请不要认为您的应用程序已正确连接.root指令必须指向正确的文件夹来解析静态资产.
