Question

我正在尝试更新用户的个人资料图片。用户的个人资料将在用户创建时自动创建。那时设置了默认头像。

我正在使用令牌身份验证

Authorization : Token a877b60afeb45e1ada12e10ecf4d0c8065b15569

但是在尝试更新我的

时

request.data

<QueryDict: {'date_of_birth': ['1990-05-02'], 'profile_image': [<InMemoryUploadedFile: image_5854.jpg (image/jpeg)>]}>

serilizer.data

{'profile_image': None, 'date_of_birth': '1990-05-02'}

的 Models.py

@deconstructible

class UploadToPathAndRename(object):

    def __init__(self, path):
        self.sub_path = path

    def __call__(self, instance, filename):
        ext = filename.split('.')[-1]
        # get filename
        if instance.pk:
            filename = '{}.{}'.format(instance.pk, ext)
        else:
            # set filename as random string
            filename = '{}.{}'.format(uuid4().hex, ext)
        # return the whole path to the file
        return os.path.join(self.sub_path, filename)

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    date_of_birth = models.DateField(null=True, blank=True)
    profile_image = models.ImageField(upload_to=UploadToPathAndRename(os.path.join('images/avatar/')),
                                      default='images/avatar/default.jpg')
    participated = models.IntegerField(default=0)
    won = models.IntegerField(default=0)
    runner_up = models.IntegerField(default=0)


@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
    if created:
        Profile.objects.create(user=instance)


@receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
    instance.profile.save()

Serializers.py

class ProfilePUTSerializer(ModelSerializer):
    profile_image = ImageField(max_length=None, use_url=True)

    class Meta:
        model = Profile
        fields = ('profile_image', 'date_of_birth',)

Views.py

class ProfilePUTAPIView(APIView):
    authentication_classes = (TokenAuthentication,)
    permission_classes = (IsAuthenticated,)

    def put(self, request):
        print(request.data)
        print(request.content_type)
        print(request.stream)
        serializer = ProfilePUTSerializer(data=request.data)
        if serializer.is_valid():
            user = Profile.objects.get(user_id=request.user.pk)
            user.__dict__.update(serializer.data)
            user.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

请建议做什么？感谢

在通过序列化程序获取更新配置文件后，ImageField设置为null DRF | Django Rest Framework
