Django get（）返回了多个主题，而filter没有

Question

我对Django中的get（）有问题。我有这样的功能：

  try:
      sth = Object.objects.get(t=request.GET.get('data'))
      if request.method == 'GET':
        serializer = ObjectSerializer(sth)
        return Response(serializer.data)

我有个错误：

^{pr2}$

所以我用get替换了filter：

sth = Object.objects.filter(t=request.GET.get('data'))

但现在我得到了一个错误：

AttributeError: Got AttributeError when attempting to get a value for field `data` on serializer `ObjectSerializer`.
The serializer field might be named incorrectly and not match any attribute or key on the `QuerySet` instance.
Original exception text was: 'QuerySet' object has no attribute 'data'.

有什么建议吗？

从queryset创建序列化程序时，Simple指定many=True。在

  sth = Object.objects.filter(t=request.GET.get('data'))
  if request.method == 'GET':
      serializer = ObjectSerializer(sth, many=True) 
      return Response(serializer.data)
