没有路线符合[GET]/资产

问题描述

我有一个Rails应用，正在尝试在生产环境中进行测试.我运行了RAILS_ENV=production rake assets:precompile，它在/public/assets中生成了我的所有资产.问题是，当我使用RAILS_ENV=production rails s thin启动我的应用时，我得到了:

I have a Rails app that I'm trying to test in the production environment. I ran RAILS_ENV=production rake assets:precompile which generated all of my assets in /public/assets. The problem is that when I start my app w/ RAILS_ENV=production rails s thin I get:

ActionController::RoutingError (No route matches [GET] "/assets/application-eff78fd67423795a7be3aa21512f0bd2.css"):

此文件确实存在，但位于/public/assets/application-eff78fd67423795a7be3aa21512f0bd2.css.

This file does exist though at /public/assets/application-eff78fd67423795a7be3aa21512f0bd2.css.

关于我为什么要得到这个RoutingError的任何想法?

Any thoughts as to why I'm getting this RoutingError?

推荐答案

在生产模式下，Rails将不负责提供静态资产.因此，您会收到此错误. Thin不会做任何事情，因为它只是Rails的包装.

In production mode, Rails will not be responsible for serving static assets. Therefore, you are getting this error. Thin won't do it either, since it's just a wrapper around Rails.

这由您应用程序中config/environments/production.rb中的此设置控制:

This is controlled by this setting in config/environments/production.rb in your application:

config.serve_static_files = false

或在Rails 5中:

Or in Rails 5:

# config/environments/production.rb
config.public_file_server.enabled = true

或将ENV['RAILS_SERVE_STATIC_FILES']设置为true.

您可以设置为true，也可以使用将为静态资产提供服务的真实服务器(如Apache或Nginx).我怀疑Pow也可能会这样做.

You can either set to that true or use a real server like Apache or Nginx which will serve the static assets. I suspect Pow may also do it.

如果您使用的是Heroku，他们建议使用rails_12factor gem，默认情况下启用此设置.将宝石放入Gemfile中的production组中，如下所示:

If you're on Heroku, they recommend the use of the rails_12factor gem which enables this setting by default. Place the gem into a production group in your Gemfile, like this:

group :production do
  gem 'rails_12factor'
end
