Question

我有这些序列化器：

# Tickets
class TicketSerializer(serializers.ModelSerializer):
    class Meta:
        model = Ticket
        depth = 2

class TicketWriteSerializer(serializers.ModelSerializer):
    class Meta:
        model = Ticket

和这个观点：

class Tickets(generics.ListCreateAPIView):
  model = Ticket
  serializer_class = TicketSerializer

  def create(self, request, *args, **kwargs):
    serializer = TicketWriteSerializer(data=request.DATA, files=request.FILES)
    if serializer.is_valid():
      self.pre_save(serializer.object)
      self.object = serializer.save(force_insert=True)
      self.post_save(self.object, created=True)
      headers = self.get_success_headers(serializer.data)
      serializer = TicketSerializer(serializer.object)
      return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers)

    return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

并在我的urls文件中添加如下：

  url(r'^tickets/', Tickets.as_view(model=Tickets), name='tickets')

此模型：

class Ticket(models.Model):
    customer = models.ForeignKey('Customer', null=True, blank=True)
    act = models.ForeignKey('Act')
    row = models.PositiveIntegerField()
    seat = models.PositiveIntegerField()
    # Price for a seat can go up to 9999.99
    price = models.DecimalField(max_digits=6, decimal_places=2)
    status = models.CharField(max_length=255)

现在每当我打电话/门票/我得到：

AttributeError at /tickets/

type object 'Tickets' has no attribute '_default_manager'

我想知道它是怎么回事。我想要的是两个Serializer，所以我可以发送数据＆＃34; flat＆＃34;和ForeignKeys一样，但是使用deep = 2的所有数据检索它们。

Answer 1

您设置了model=Tickets，但Tickets是您的观点，而不是您的模型。

url(r'^tickets/', Tickets.as_view(model=Tickets), name='tickets')

改为使用

url(r'^tickets/', Tickets.as_view(model=Ticket), name='tickets')

ListCreateAPIView对象没有属性＆＃39; _default_manager＆＃39;
