AttributeError: type object 'ContactsViewSet' has no attribute 'get_extra_actions'

[riquedev]

Guys, I am not able to raise the server due to this error after I have inserted the necessary classes for the use of Bulk.

AttributeError: type object 'ContactsViewSet' has no attribute 'get_extra_actions'

Here's a snippet of what I'm doing.

(app)/urls.py

urlpatterns = [
    path('api/', include('bots_api.urls')),
]

bots_api/urls.py

bulk_routes = [
    ('contacts/list', ContactsViewSet, 'Contacts List'),
    ('contacts/details', ContactsDetailsViewSet, 'Contacts List'),
    ('contacts/blacklist', ContactBlackListViewSet, 'Contacts Black List')
]

bulk_router = BulkRouter()

for route in bulk_routes:
    bulk_router.register(route[0],route[1],route[2])

urlpatterns = [
    path('',include(bulk_router.urls)),
]

serializers/contacts.py

class ContactsSerializer(BulkSerializerMixin, serializers.ModelSerializer):
    class Meta(object):
        from bots_api.models import Contacts
        model = Contacts
        fields = ('__all__')
        list_serializer_class = BulkListSerializer

views/contacts.py

class ContactsViewSet(ListBulkCreateUpdateDestroyAPIView):
    from bots_api.lib.serializers.contacts import ContactsSerializer
    serializer_class = ContactsSerializer

    filter_backends = (filters.OrderingFilter,
                       filters.SearchFilter,
                       DjangoFilterBackend)

    search_fields = ['phone_number', 'phone_region', 'phone_type', 'tag', 'created',
                     'updated']

    def get_queryset(self):

        contact_id = self.request.query_params.get('id', None)
        client_id = self.request.query_params.get('client', None)
        number = self.request.query_params.get('number', None)
        active = self.request.query_params.get('active', None)

        queryset = self.ContactsSerializer.Meta.Contacts.objects.all()

        if contact_id:
            queryset = queryset.filter(id=contact_id)

        if client_id:
            queryset = queryset.filter(client_id=client_id)

        if number:
            queryset = queryset.filter(phone_number__contains=number)

        if not active is None:
            queryset = queryset.filter(active=active)

        return queryset

I've been having this problem since yesterday, does anyone know where I might be going wrong?

same here

[Karmenzind]

@tolsac @riquedev get_extra_action is only in rest_framework >= 3.8 and work with decorator @action.

Install an earlier version may temporarily fix this issue.

@tolsac @riquedev
Sorry I was wrong.

I guess riquedev's issue is because he treated an APIView obj as a ViewSet.

class ContactsViewSet(ListBulkCreateUpdateDestroyAPIView):

The ways that they are added to routers are quite different. Check https://www.django-rest-framework.org/api-guide/routers/#using-include-with-routers
Try .as_view() instead.

[Luid101]

Just to clarify what @Karmenzind said changing:

class ContactsViewSet(ListBulkCreateUpdateDestroyAPIView):

to:

class ContactsViewSet(BulkModelViewSet):

Should fix that issue.

I ran into the same issue and fixed it for me.

Also, it would be nice if there was more information on setting up ViewSets

@Luid101 Thanks for the info. This worked for me
