Rails 4 弹性搜索日志记录的生产问题

Question

我正在 rails 4.2.11.3 应用程序和 ruby 2.5.0 应用程序中实现 Heroku 上的 Elasticsearch，用于用户模型的基本搜索。在heroku staging环境下，完美运行，但是在生产环境下，我在导入模型的时候遇到了这个错误。

irb(main):001:0> User.import

ArgumentError (undefined class/module Logger::SimpleFormatter)

Rails.logger 是：

irb(main):002:0> Rails.logger
=> #<ActiveSupport::Logger:0x0000563a356d7070 @level=2, @progname=nil, @default_formatter=#<Logger::Formatter:0x0000563a356d6e40 @datetime_format=nil>, @formatter=#<ActiveSupport::Logger::SimpleFormatter:0x0000563a356d6be8 @datetime_format=nil>, @logdev=#<Logger::LogDevice:0x0000563a356d6d78 @shift_period_suffix=nil, @shift_size=nil, @shift_age=nil, @filename=nil, @dev=#<IO:<STDOUT>>, @mon_owner=nil, @mon_count=0, @mon_mutex=#<Thread::Mutex:0x0000563a356d6c88>>, @local_levels=#<ThreadSafe::Cache:0x0000563a356d6ad0 @backend={}, @default_proc=nil>>

我知道 Logger::SimpleFormatter 已从 rails 4.1 中删除，我应该使用 ActiveSupport::Logger::SimpleFormatter。我知道生产 log_formatter 默认为 Logger::Formatter。我在 config/environments/production.rb 中尝试了多种配置变体，但无济于事，并且还添加了 rails_12factor gem，它将 Rails.logger 切换为：

<RailsStdoutLogging::StdoutLogger:0x000055fbb41bca28 @level=2, @progname=nil, @default_formatter=#<Logger::Formatter:0x000055fbb41bc988 @datetime_format=nil>, @formatter=#<ActiveSupport::Logger::SimpleFormatter:0x000055fbb41bc8c0 @datetime_format=nil>, @logdev=#<Logger::LogDevice:0x000055fbb41bc938 @shift_period_suffix=nil, @shift_size=nil, @shift_age=nil, @filename=nil, @dev=#<IO:<STDOUT>>, @mon_owner=nil, @mon_count=0, @mon_mutex=#<Thread::Mutex:0x000055fbb41bc8e8>>, @local_levels=#<ThreadSafe::Cache:0x000055fbb41bc898 @backend={}, @default_proc=nil>>

如果我引入我自己的 Logger::SimpleFormatter class，继承自 ActiveSupport::Logger::SimpleFormatter，它解决了问题，但错误移动到：

undefined class/module Logger::LogDevice::LogDeviceMutex

问题是我们在数据库中有遗留的 Braintree 对象，当我们执行 ES 导入时，这些对象正在调用 rails 3 记录器
