Question

仅当我使一个模型具有对同一模型的2个继承时，才会发生这种情况：

colorControlNormal

一切正常，但是访问第二页会给我一个空数组：

第一页：

class Word(models.Model):
    cuvint = models.ForeignKey(KeyWordsMapping, on_delete=models.CASCADE, related_name="%(class)s_cuvint")
    frequency = models.IntegerField()
    is_stem = models.BooleanField()
    score_nr = models.ForeignKey(KeyWordsMapping, on_delete=models.CASCADE, related_name="%(class)s_score_nr")
    department_id = models.ForeignKey(Department, on_delete=models.CASCADE, blank=True, null=True)
    seniority_id = models.ForeignKey(Seniority, on_delete=models.CASCADE, blank=True, null=True)

第二页：

{
    "count": 311,
    "next": "http://127.0.0.1:8000/api/words?limit=1&offset=1",
    "previous": null,
    "results": [
        {
            "cuvint": "QA",
            "frequency": 4,
            "is_stem": false,
            "score_nr": 100,
            "department_id": "Quality Assurance",
            "seniority_id": null
        }
    ]
}

我也在管理面板中查看，同样的问题仍然存在。

视图：

{
    "count": 311,
    "next": "http://127.0.0.1:8000/api/words?limit=1&offset=2",
    "previous": "http://127.0.0.1:8000/api/words?limit=1",
    "results": []
}

序列化器：

class WordList(mixins.ListModelMixin,
                mixins.RetrieveModelMixin,
                generics.GenericAPIView):
    queryset = Word.objects.all()
    serializer_class = WordSerializer

    def get(self, request, *args, **kwargs):
        return self.list(request, *args, **kwargs)

Djongo在下一页时返回空的QuerySet
