'我是Django的新手，试图将我的表单数据保存在database.created两个模型classes PatientInfo和patientHist中，它继承了PatientInfo class。我不明白我哪里出错了。 '.我没有收到任何错误，我的表是在数据库中创建的，但是当我点击提交按钮时没有数据被保存'

您好，我终于找到您的错误了。

您有一个字段 currentmed，它是 CharField。

但是在 forms.py 中，您为它分配了 forms.RadioSelect 小部件。所以它会为必填字段抛出错误。

所以只需从 PatientHistory_form 的 widget 字典中删除 'currentmed':forms.RadioSelect,。

就是这样。

无法在数据库中保存模型表单数据。给出 patientmedinfo.errors = none 和 patientmedinfo.is_valid() = false
