DjangoRestFramework循环问题，它仅在第一个元素上运行

Question

它应该运行3次，但仅对第一个元素运行。我试图在python控制台上运行它，并且相同的方法效果很好。我无法弄清楚代码的问题。

@api_view(['POST'])
def SaveVisitView(request):
    if request.method == 'POST':
        visits = json.loads(request.POST.get('request'))
        for i in range(len(visits['visits'])):
            serializer = VisVisitsSerializer(data=visits['visits'][i])

            if serializer.is_valid():
                serializer.save()
            else:
                return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
            return Response(serializer.data, status=status.HTTP_201_CREATED)

型号

class VisVisits(models.Model):    
    visit_id = models.IntegerField(primary_key=True,auto_created=True)
    app_local_id = models.IntegerField(blank=True, null=True)
    school_program = models.ForeignKey(SchProgramForSchools, models.DO_NOTHING, blank=True, null=True)
    user = models.ForeignKey(UsrUsers, models.DO_NOTHING, blank=False, null=False)

    class Meta:
        managed = False
        db_table = 'vis_visits'

    def __str__(self):
        return str(self.visit_id)

数据

{
 "user": "1",
 "visits": [
    {
      "action": "i",
      "local_id": "170",
      "visit_id": "",
      "school_program_id": "1",
    },

    {
      "action": "i",
      "local_id": "172",
      "visit_id": "",
      "school_program_id": "1",
    },

    {
      "action": "i",
      "local_id": "172",
      "visit_id": "",
      "school_program_id": "1",
    },

  ]
}

如何在序列化程序中使用many=True属性？ 它可以处理多个对象。

也看this。

@api_view(['POST'])
def SaveVisitView(request):
    if request.method == 'POST':
        visits = json.loads(request.POST.get('request'))
        serializer = VisVisitsSerializer(data=visits['visits'], many=True)

        if serializer.is_valid():
            serializer.save()
        else:
            return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
        return Response(serializer.data, status=status.HTTP_201_CREATED)
