如何在Heroku上的rails应用程序上完全关闭资产编译?

我有一个rails应用程序,它运行没有资产的服务。 当我部署时,我看到:

-----> Preparing app for Rails asset pipeline Running: rake assets:precompile rake aborted! could not connect to server: Connection refused Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432? /tmp/build_3pneyggcg60ks/vendor/bundle/ruby/2.0.0/gems/activerecord-3.2.14/lib/active_record/connection_adapters/postgresql_adapter.rb:1222:in `initialize' /tmp/build_3pneyggcg60ks/vendor/bundle/ruby/2.0.0/gems/activerecord-3.2.14/lib/active_record/connection_adapters/postgresql_adapter.rb:1222:in `new' /tmp/build_3pneyggcg60ks/vendor/bundle/ruby/2.0.0/gems/activerecord-3.2.14/lib/active_record/connection_adapters/postgresql_adapter.rb:1222:in `connect' ... 

所以我把它放到我的application.rb中:

 config.assets.enabled = false config.serve_static_assets = false config.assets.compile = false 

但是在部署时我仍然会收到相同的消息。

如何在heroku上完全关闭资产编译/处理?

请参阅此问题和文档 。 看起来像manifest.yml文件中的魔术。

在https://devcenter.heroku.com/articles/rails-asset-pipeline上找到了这个

在预编译资产时,在Rails 3.x中,您可以通过确保config/application.rb中包含以下行来阻止初始化应用程序并连接到数据库:

 config.assets.initialize_on_precompile = false
