“缺少计数”属性在“模型”视图中

Question

我正在使用Modelviewsets，一切正常，预计响应中没有count参数。我怀疑可能是分页不起作用，但我在DRF设置中定义了分页

设置：

'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
'PAGINATE_BY': 100,                 # Default to 10
'PAGINATE_BY_PARAM': 'page_size',  # Allow client to override, using `?page_size=xxx`.
'MAX_PAGINATE_BY': 10             # Maximum limit allowed when using `?page_size=xxx`.

观点：

class VenueViewSet(viewsets.ModelViewSet):
    """
    Manage CRUD on venues here
    """
    queryset = Venue.objects.all()
    serializer_class = serializers.VenueSerializer
    filter_backends = (ModifiedFilterBackend,)
    paginate_by = settings.VENUES_PAGINATION

      "city": {

        "country": {
          "name": "XYZ",
          "code": "XY"
        },
        "id": 22
      },
      "address_line_1": "abcd",
      "address_line_2": "qwert",
      "zip_code": 123654,
      "place_id": null
    },
    "is_deleted": false,
    "parent": null
  }
]

我认为您错过了PAGE_SIZE设置。请参考this。

REST_FRAMEWORK = {
'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
'PAGE_SIZE': 100
}
