如果有人知道在哪里看，我一直在努力解决这个错误，我会非常感激。
问题：我在我的应用程序中运行ActiveAdmin，它在我本地运行时运行正常，但是当我在Heroku上运行时，我可以使用我的应用程序的所有功能，除了使用一个名为＆＃34的管理界面;任务＆＃34 ;.
当我打开＆＃34;任务＆＃34;我收到内部错误500。
我的ActiveAdmin的其他功能完美运行，我可以将数据保存到我的数据库。
这是我的宝石文件：

如果有人知道我该怎么做，我将永远感激不尽！如果我应该显示其他文件来解决这个问题，请告诉我，我会在这里添加它们。
答案 0 :(得分：0)
我可以通过将sorting_attribute: :tag更改为sorting_attribute: :project_id
我知道这可能不是最好的方法，但它解决了我的问题。非常感谢你评论并给了我明智的帮助，我欠你很大的时间！
