Question

我正在将多个值发布到我的“ KeyboardEventView” ModelViewSet中。发布成功，我可以看到数据库中的数据已正确记录。但是，我收到了Django抛出的错误，

...

    values = list(values)
TypeError: 'ListSerializer' object is not iterable

这真让我发疯。它可以工作，但是看到抛出错误会很麻烦。还有其他人遇到这种情况吗？

----- Views.py -----

class KeyboardEventView(viewsets.ModelViewSet):
    queryset = KeyboardEvent.objects.all()
    serializer_class = KeyboardEventSerializer

    def get_serializer(self, *args, **kwargs):
        if "data" in kwargs:
            data = kwargs["data"]

            # check if many is required
            if isinstance(data, list):
                kwargs["many"] = True

        return super(KeyboardEventView, self).get_serializer(*args, **kwargs)

----- Models.py -----

class KeyboardEvent(models.Model):
    value = models.CharField(max_length=15)
    time = models.DateTimeField(auto_now=True)
    user_id = models.ForeignKey(UserData,on_delete=models.CASCADE)
    def __str__(self):
        return self.value
