Django ForeignKey field required despite blank=True and null=True

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)
