未提供Rails Cloudfront资产 [英] Rails Cloudfront assets not served

问题描述

我使用Heroku for Rails设置Cloudfront，一开始它运行良好。我在最后几天注意到资产不再从cloudfront.net提供服务。

Production.rb

  Rails.application.configure do 
 config.cache_classes = true 
 config.eager_load = true 
 config.consider_all_requests_local = false 
 config .action_controller.perform_caching = true 
 config.action_controller.asset_host ='http://d2t6o5tnu5etuf.cloudfront.net'
 config.serve_static_files = true 
 config.assets.js_compressor =：uglifier 
 config.assets.css_compressor =：sass 
 config.assets.compile = true 
 config.assets.digest = true 
 config.assets.version ='1.0'
 config .log_level =：info 
 config.i18n.fallbacks = true 
 config.active_support.deprecation =：notify 
 config.log_formatter = :: Logger :: Formatter.new 
 config。 active_record.dump_schema_after_migration = false 
 end 
  

我可以在云端地址下找到我的所有资产，在铬我可以看到应用程序5de b6995ce9b984d469b27c58cc92a095d19cd13e0acd622ffe426c41826e055.js从云端服务器获取。然而，页面上的所有静态图像例如/assets/shop/banners/2.jpg不要。

它似乎与预编译有关，因为它不查找指纹文件的版本，或者？

在我的gem文件中，我有以下内容：

  group：production，：staging do 
 gem'rails_12factor'
 gem'pg'
 end 
  

解决方案

随着tegon的发展，需要image_tag或image_url来为cloudfront中的资产提供服务。我在我的代码中有通常的img src引用，它不会被识别。

将img src更改为image_tag或image_url，它正在工作。谢谢！

I set-up Cloudfront with Heroku for Rails and in the beginning it worked fine. I noticed in the last days that the assets are not served from cloudfront.net any longer.

Production.rb

Rails.application.configure do
  config.cache_classes = true
  config.eager_load = true
  config.consider_all_requests_local       = false
  config.action_controller.perform_caching = true
  config.action_controller.asset_host = 'http://d2t6o5tnu5etuf.cloudfront.net'
  config.serve_static_files = true
  config.assets.js_compressor = :uglifier
  config.assets.css_compressor = :sass
  config.assets.compile = true
  config.assets.digest = true
  config.assets.version = '1.0'
  config.log_level = :info
  config.i18n.fallbacks = true
  config.active_support.deprecation = :notify
  config.log_formatter = ::Logger::Formatter.new
  config.active_record.dump_schema_after_migration = false
end

I can reach all my assets under the cloudfront adress and in chrome i can see that application-5deb6995ce9b984d469b27c58cc92a095d19cd13e0acd622ffe426c41826e055.js gets served from cloudfront server. However all static images on the page e.g. /assets/shop/banners/2.jpg do not.

It seems to have to do with the precompiling, since it does not look for the fingerprint version of the file, or?

In my gem-file I have the following included:

group :production, :staging do
      gem 'rails_12factor'
      gem 'pg'
 end

解决方案

As tegon poined out, image_tag is or image_url is needed to serve the assets from cloudfront. I had the usual "img src" reference in my code, which will not be recognized.

Changed img src to image_tag or image_url and it was working. Thanks!
