自定义DRF列表函数不返回某些dict键/值对

Question

我试图用自定义视图替换Django REST Framework视图集内的标准列表函数，但是却失去了计数，上一个，下一个参数。 没有覆盖，列表函数将返回以下内容：

{
    "count": 3,
    "next": null,
    "previous": null,
    "results": [...]
}

而当我覆盖该函数时，我只会得到结果列表，而不是带有count，next，previous等的更高级别的dict。

此处缺少以下功能的哪一部分可以启用该功能？

def list(self, request):
    loc = Location.objects.filter(user=request.user).latest('timestamp')
    nearby = loc.get_near()  # returns a list with dicts that contain user and dist

    nearby_users = [n['user'] for n in nearby]  # gets a list of users

    serializer = self.get_serializer(nearby_users, many=True)

    return Response(serializer.data)

Answer 1

您可以添加分页

def list(self, request):
    loc = Location.objects.filter(user=request.user).latest('timestamp')
    nearby = loc.get_near()  # returns a list with dicts that contain user and dist

    nearby_users = [n['user'] for n in nearby]  # gets a list of users

    # start pagination
    page = self.paginate_queryset(nearby_users)
    if page is not None:
        serializer = self.get_serializer(page, many=True)
        return self.get_paginated_response(serializer.data)
    # end pagination

    serializer = self.get_serializer(nearby_users, many=True)

    return Response(serializer.data)
