nginx在生产模式下加载错误的资产文件路径

Question

nginx试图给我这样的资产文件。

  

获取http://www.lazyair.co/assets/kode/css/font-awesome.min.css

但那些文件不存在。实际的文件路径应该是丑陋的。

  

获取http://www.lazyair.co/assets/kode/css/font-awesome2131e1321e12qd.min.css

Demo website

nginx.conf上的错误根本原因

  location ^~ /assets/ {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

nginx.conf

  root /home/sample/rails-app/public ;

  location ^~ /assets/ {
    gzip_static on;
    expires max;
    add_header Cache-Control public;
  }

  try_files $uri/index.html $uri @rails-app;

  location @rails-app {
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_pass http://rails-app;
    # Reverse proxy cache
    proxy_cache default;
    proxy_cache_lock on;
    proxy_cache_use_stale updating;
    add_header X-Cache-Status $upstream_cache_status;
  }

production.rb

  config.serve_static_files = false

  # Compress JavaScripts and CSS.
  config.assets.js_compressor = :uglifier
  #config.assets.js_compressor = :yui
  config.assets.css_compressor = :sass   
  config.assets.digest = true
