我使用的是添加分页的端点，因此在DRF API视图中运行良好，但是当我从Web应用程序调用它时，它会返回*** *** AttributeError: 'SearchViewSet' object has no attribute 'request'
我在下面解释细节。这是我的api.py分页查询集的地方，例如以下answer解释：
class StandardResultsSetPagination(PageNumberPagination):
page_size = 10
class SearchViewSet(viewsets.ModelViewSet):
'''
Class related with the Search Model, that is a tracking model where you
could find recently search by user.
'''
queryset = Search.objects.filter(
is_active=True,
is_deleted=False
).order_by('id')
permission_classes = [
permissions.AllowAny
]
pagination_class = StandardResultsSetPagination
def __init__(self,*args, **kwargs):
self.response_data = {'error': [], 'data': []}
self.data = {}
self.code = 0
def get_serializer_class(self):
if self.action in ['recent_search']:
return RecentSearchAPISerializer
return SearchSerializer
@validate_type_of_request
@action(methods=['post'], detail=False)
def recent_search(self, request, *args, **kwargs):
'''
- POST method (recent_search): get user recent search
- Mandatory: user, social_network_id
'''
try:
serializer = SearchSerializer(
data=kwargs['data'],
fields=['social_network','user'])
if serializer.is_valid():
queryset = Search.objects.filter(
is_active=True,
is_deleted=False,
social_network=kwargs['data']['social_network'],
user_id=kwargs['data']['user']).order_by('id').reverse()
page = self.paginate_queryset(queryset)
if page is not None:
serializer = SearchSerializer(page, many=True, fields=(
'id','word','polarity','liked','shared','searched_date'))
self.data['recently_search'] = json.loads(json.dumps(serializer.data))
self.code = status.HTTP_200_OK
self.response_data['data'].append(self.data)
return self.get_paginated_response(serializer.data)
serializer = SearchSerializer(queryset, many=True, fields=(
'id','word','polarity','liked','shared','searched_date'))
self.data['recently_search'] = json.loads(json.dumps(serializer.data))
self.code = status.HTTP_200_OK
self.response_data['data'].append(self.data)
else:
return Response(serializer.errors,status=status.HTTP_400_BAD_REQUEST)
except Exception as e:
logging.getLogger('error_logger').exception("[API - RecentSearchTwitterView] - Error: " + str(e))
self.code = status.HTTP_500_INTERNAL_SERVER_ERROR
self.response_data['error'].append("[API - RecentSearchTwitterView] - Error: " + str(e))
return Response(self.response_data,status=self.code)
在我的views.py
class RecentSearchTwitterView(View):
"""docstring for RecentSearchTwitterView"""
def __init__(self,*args, **kwargs):
self.response_data = {'error': [], 'data': {}}
self.code = 0
def get(self, request, *args, **kwargs):
try:
_recent_search = SearchViewSet()
_recent_search.recent_search(request,social_network=1,user=1)
self.response_data['data'] = _recent_search.response_data['data'][0]
self.code = _recent_search.code
except Exception as e:
logging.getLogger('error_logger').exception("[RecentSearchTwitterView] - Error: " + str(e))
self.code = status.HTTP_500_INTERNAL_SERVER_ERROR
self.response_data['error'].append("[RecentSearchTwitterView] - Error: " + str(e))
return render(request,template_name='web/recent_search_twitter.html',status=self.code,context=self.response_data)
因此，在两种情况下，在api.py中，queryset返回数据，但在下一行：
page = self.paginate_queryset(queryset)
从Web App返回错误，而在DRF Api视图中或由邮递员返回分页的数据。即使我在这一行中通过了request：
_recent_search = SearchViewSet(request)
我收到了同样的错误。我试图调试错误，但找不到解决方案。我发现了这个similar question，但我认为情况有所不同，因为queryset总是正确地返回数据
从Web App请求调试：

我无法更好地解释问题，对发生的事情有任何想法吗？
