Caching a ViewSet with DRF : TypeError: _wrapped_view()

Question

我只想对 ViewSet 使用缓存太慢了:(，使用 Django REST Framework。

我这样做过：

...
from django.utils.decorators import method_decorator
from django.views.decorators.cache import cache_page
from django.views.decorators.vary import vary_on_cookie
...
class PRPKViewSet(viewsets.ModelViewSet):
    serializer_class = PrpkSerializer
    queryset = Prpk.objects.all().order_by('begin')
    # Authentification !
    permission_classes = (IsAuthenticated,)
    # Only 'get' method
    http_method_names = ['get']

    # Cache requested url for each user for 2 hours
    # @method_decorator(vary_on_cookie)
    @method_decorator(cache_page(60*2))
    def get_queryset(self):
        """ allow rest api to filter by submissions """
        queryset = Prpk.objects.all().order_by('begin')
        highway = self.request.query_params.get('highway', None)
        if highway is not None:
            queryset = queryset.filter(highway=highway)

        return queryset

但是在查询时，我遇到了这个错误：

TypeError: _wrapped_view() missing 1 required positional argument: 'request'

已安装 Memcached。

那么，我可以只缓存一个 ViewSet（不使用扩展吗？）？

非常感谢。

装饰 dispatch 而不是 get_queryset。

@method_decorator(cache_page(60*2))
def dispatch(self, request, *args, **kwargs):
    return super().dispatch(request, *args, **kwargs)
