我使用： 铁路4.1.7 红宝石2.1.4宝石 “审计 - ActiveRecord的”，“〜> 4.0给出了未定义的方法'审计
我刚刚安装Audited GEM：
gem "audited-activerecord", "~> 4.0"
$ rails generate audited:upgrade
$ rake db:migrate
型号
class Opportunity < ActiveRecord::Base
...
audited
...
end
当我运行：
Opportunity.audits.count
我得到这个错误：
2.1.4 :001 > Opportunity.audits.count
NoMethodError: undefined method `audits' for #<Class:0x007ff7946656f0>

我使用Ruby 2.1.4并有警示标志“审计可以工作得很好，上面没有列出一个Ruby版本（2.1.2 Latested），但我们不能保证它会。如果你想保持未列出一个Ruby，请让我们知道有一个拉请求。”
有没有人经历过这个？
