我在rails中创建了一个模型类，并在本地开发和生产环境中进行了测试。 然而，我将rails应用程序部署到AWS，发现了一个非常奇怪的问题。 我不能再使用我的模型了

比如说,

Loading production environment (Rails 4.1.6)
Mgmt_Server :001 > defined?(Game)
=> "constant" 
Mgmt_Server :002 > Game.create
NoMethodError: undefined method `[]' for nil:NilClass ... etc

在我对游戏进行一些更改之后。rb=>

class Game < ActiveRecord::Base
  has_many :game_defaults
  #has_many :game_save   (remove this line)
end

使用定义的
DISABLE_SPRING=1
环境变量尝试相同的操作，它似乎调用了AR，而AR又调用了beefcake，如果没有后续序列化游戏保存对象的标头数据，则无法初始化

如果它有助于重新部署
——无需开发测试

什么是回溯？你在那里运行过迁移吗？当然，我会多次删除和迁移。你能超过1吗。回溯和2。游戏类代码？第一点很关键，什么是牛排？这就是问题所在。请看一下导致问题的beefcake中的线路。
