Answer 1

我想我认识到这个问题。看起来acts_as_audited使用缓存清理程序。我遇到了缓存清扫器的问题。

您需要在ApplicationController中明确包含缓存模块：

class ApplicationController < ActionController::Base

  # JRuby not finding cache sweeper at runtime in production
  include ActionController::Caching::Sweeping if defined?(JRUBY_VERSION)

  # Rest of your class here...

end

我不确定为什么会发生这种情况，但这可能是与线程安全模式下的生产相关的加载/解决问题。

Answer 2

我在jruby-rack中将此问题报告为a bug。

解决方法是在{/ 1}}之后的config / boot.rb中添加require 'active_record' if defined? $servlet_context，或在application.rb require 'rubygems'中手动包含扫描somwhere。

ActionController :: Base的未定义方法`cache_sweeper'：类 - warbler
