问题 I am using Django REST Framework and I have a MyNodel with a related MyOtherModel in a many-to-one relationship: models.ForeignKey(MyModel, related_name="my_other_models", blank=True, null=True) Although blank=True, null=True , when I try to post a MyModel JSON without a my_other_models field I get a "this field is required" error. 回答1: In your serializer, you need to add required=False . field = MyModelSerializer(required=False) 来源： https://stackoverflow.com/questions/40237969/django
