Python Django:使用已操纵的.csv文件保存数据库|错误：“”；值的日期格式无效

我有一个csv文件，它由另一个平台定期更新。我正在尝试将此csv文件导入我的数据库。但csv文件样式（如日期字段、空白字段或选择字段）与django不匹配。所以我需要处理这个文件，然后我要导入到我的数据库中

即使我在我的脚本中编辑了这个csv文件，并且看起来很像csv文件，但是我还是遇到了以下错误

错误

django.core.exceptions.ValidationError: ['“” value has an invalid date format. It must be in YYYY-MM-DD format.']

还有一个错误

django.core.exceptions.ValidationError: ['“” value has an invalid date format. It must be in YYYY-MM-DD format.']

我错过了什么？为什么准备好的csv文件看起来不错，Django试图更正字段类型？你能给我指路吗
