Django Rest API : How to get rid of 'UUID' in json when serializing models?

Question

为什么 'UUID' 出现在 'profile' 键的值前面，如何正确删除它？

名册/serializers.py

class ShiftSerializer(serializers.ModelSerializer):

class Meta:
    model = Shift
    fields = ('id', 'profile', 'location', 'date', 'start_time', 'end_time')

配置文件/模型.py

class Profile(models.Models):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=True)

名册/models.py

    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=True)
    profile = models.ForeignKey('profiles.Profile', null=True, blank=True)

python manage.py shell

from roster.models import Shift
from roster.serializers import ShiftSerializer

myshift = Shift.objects.first()
serializer = ShiftSerializer(myshift)
serializer.data

输出:

{'id': '92ca258e-8624-434a-b61d-e1cd3b80e0e8', 'profile': UUID('0081b028-0a11-47fb-971e-c47177ed93be')

您可以重写 representation ，像这样

class ShiftSerializer(serializers.ModelSerializer):
    class Meta:
        model = Shift
        fields = '__all__'

    def to_representation(self, obj):
        return {
            "id": obj.id,
            "profile": obj.profile.id,
            "location": obj.location,
            "date": obj.date,
            "start_time": obj.start_time,
        }
