Django AttributeError: 'str' object has no attribute 'get' - django

Question

When visiting a url it returns a error mentioned in the question title.
The View itself is a ListView.
When i debuged the view, it only looped through the dispatcher function and return the following error without getting to queryset.
Here's the code.
ListView
class MailingListView(ListView, LoginRequiredMixin):
# model = MailingList
template_name = 'mailinglist/mailing_list.html'
def get_queryset(self):
return MailingList.objects.filter(owner=self.request.user)
def dispatch(self, request, *args, **kwargs):
if not request.user.is_authenticated:
return reverse('user:login')
return super().dispatch(request, *args, **kwargs)
Model
class MailingList(models.Model):
id = models.UUIDField(primary_key=True, default=uuid.uuid4(), editable=False)
name = models.CharField(max_length=140)
owner = models.ForeignKey(to=user_model,
on_delete=models.CASCADE)
def __str__(self):
return self.name
def get_absolute_url(self):
return reverse('mailinglist:manage_list', kwargs={'pk': self.id})
def user_can_use_mailinglist(self, user):
return user == self.owner

Answer 1

reverse() returns a string. But you are supposed to return HTTP responses.
Change in dispatch in MailingListView.
from django.http import HttpResponseRedirect
return HttpResponseRedirect(reverse('user:login'))
