我只想使用缓存到ViewSet的速度太慢:(,使用Django REST Framework。
我已经这样做了:
...
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'
Memcached已安装。
因此,我可以仅缓存一个ViewSet(不使用扩展名吗?)?
非常感谢。
F。
答案 0 :(得分:1)
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)
