我正在设置ActiveAdmin，当我使用编辑操作来更新我提交的任何模型时，会导致struct'样式中的'no member'错误。我当然可以看到发布的结构中的model_name IS，所以我很困惑。我不确定我做错了什么，也不确定如何解决。我没有更改更新操作。我几乎是一个Rails新手，但是活跃的管理员表现不错。对其中一个的回应是......

您很可能没有在product_group.rb中包含强参数 请查看此文档https://github.com/gregbell/active_admin/blob/master/docs/2-resource-customization.md#setting-up-strong-parameters
应该指向正确的方向。
