Object of type Email is not JSON serializable, How to create or update Django model object

Question

I'm trying to build an object from my Email model, if the 'user_email' which is a user_email = models.CharField(primary_key=True, max_length=200) already exists just update it, if it doesn't exist create a new我向您展示了如何創建我的新 object。

我收到以下錯誤：

TypeError: Object of type Email is not JSON serializable

我的 models.py 提取：

class Email(models.Model):
    user_email = models.CharField(primary_key=True, max_length=200)
    user_phone_number = models.IntegerField()
    user_device_id = models.CharField(max_length=200)#request.META.get('HTTP_DEVICE', '')
    lat = models.DecimalField(max_digits=22, decimal_places=16, blank=True, null=True)
    lng = models.DecimalField(max_digits=22, decimal_places=16, blank=True, null=True)
    user_address = models.CharField(max_length=200)
    creation_date = models.DateTimeField(default=None)
    email_status = models.BooleanField(default=False)
    email_score = models.IntegerField()
    valid_email = models.BooleanField(default=False)
    fraud = models.BooleanField(default=False)

我的views.py 提取：class UserListView(APIView)：serializer_class = EmailSerializer queryset = Email.objects.all() pagination_class = StandardResultsSetPagination

    def get_serializer_class(self):
        if self.action == 'list':
            return EmailListSerializer
        return EmailSerializer
    
    def post(self, request, *args, **kwargs):
        parametros = request.POST
        email='email=' + request._full_data['user_email']
        response = UserConnector(email).get_user_data()
        obgs = response[1]['results']
        if len(obgs) == 0:
            user_email = self.request.POST.get('user_email')
            email_stat = ''
            email_scor = ''
            email_valid = ''
            frau = ''
        else:
            obg = response[1]['results'][0]

            user_email = self.request.POST.get('user_email')
            email_stat = obg.get('email_status')
            email_scor = obg.get('email_score')
            email_valid = obg.get('valid_email')
            frau = obg.get('fraud')

        NewEmail = Email(
            user_email = user_email,
            user_phone_number = self.request.POST.get('user_phone_number'),
            user_device_id = request.META.get('HTTP_DEVICE', ''),
            lat = self.request.POST.get('lat'),
            lng = self.request.POST.get('lng'),
            user_address = self.request.POST.get('user_address'),
            creation_date = timezone.now,
            email_status = email_stat,
            email_score = email_scor,
            valid_email = email_valid,
            fraud = frau
        )
        return Response(NewEmail)

I create the NewEmail Object which is an instance for the Email model, then I want to do NewEmail.save() and return Response(NewEmail) for DRF to return the JSON of the created or updated object.

Answer 1

Instance (NewEmail) 不能直接在 Response 中傳遞。 您首先需要保存該實例，即 NewEmail.save()，然后將該實例傳遞給您的 EmailSerializer 序列化程序。 然后在 Response 中傳遞該序列化響應。

新電子郵件.save()

序列化程序 = EmailSerializer(NewEmail)

返回響應（serializer.data）
