You are inheriting you Deleteview from a DetailView, not a DeleteView, hence the error:
from django.views.generic import DeleteView
class Deleteview(DeleteView):
model = Task
template_name = 'delete.html'
success_url = reverse_lazy('todoapp:home')
I would however strongly advise not to give your views names like Deleteview, since it is easy to confuse this with the Django builtin class-based views. Usually the model is specified in the name, so TaskDeleteView instead of Deleteview:
class TaskDeleteView(DeleteView):
model = Task
template_name = 'delete.html'
success_url = reverse_lazy('todoapp:home')
