Ruby on rails 超类不匹配只会随着活动管理文件的删除而消失

ruby-on-rails

Ruby on rails 超类不匹配只会随着活动管理文件的删除而消失,ruby-on-rails,activeadmin,Ruby On Rails,Activeadmin,我正在为一个项目使用Rails 3.2.3和Active Admin。当我尝试对数据库进行rake时，它会说：“类BillingCycle的超类不匹配”，并且将类的名称更改为其他名称会产生相同的错误。如果我拿出了活动的管理工具（初始化器、管理文件夹、路由），我就可以运行它，但是我需要一个解决方案，它不需要我为每个db:migrate都这样做。完整跟踪是： superclass mismatch for class BillingCycle /Users/ashley/public_afm

我能做些什么来解决这个问题？

我想您可能已经将迁移计费周期命名了。检查BillingCycle的迁移文件顶部是否没有以下内容：类BillingCycle

如果是，请将该类重命名为其他类-可能是“AddingBillingCycle”。

是否像在initializers或ActiveAdmin中那样重新打开BillingCycle类以添加其他方法、设置一些默认值等？
