Question

我使用Rails 4.1.4，Unicorn 4.8.3和Ruby 2.1.1在Heroku上运行Ruby on Rails应用程序。我试图让开发和生产环境保持相似。在开发过程中，Unicorn运行得很好。

在制作中，我在日志中得到了这个：

该应用程序几乎无法启动。我在Google搜索了undefined method `[]=' for nil:NilClass (NoMethodError)错误，此处没有任何帮助。

有什么想法吗？

我能够通过更新unicorn.rb配置文件的一部分来解决这个问题。

来自：

config = Rails.application.config.database_configuration[Rails.env]

要：

config = ActiveRecord::Base.configurations[Rails.env] || Rails.application.config.database_configuration[Rails.env]

我使用的是过时的代码。 Source
