I am having trouble understanding what the Debug wants me to fix and how to
fix it?
Isn't my models already defined? Isn't my queryset already defined in
variables filter_1, 2 and 3?
Exception Type: ImproperlyConfigured Exception Value:
*'IndexView' must define 'queryset' or 'model'*
Exception Location:
/usr/local/lib/python2.7/dist-packages/django/views/generic/list.py
in get_queryset, line 35
*views.py*
from polls.models import Word, Pronunciation
#_______________________________________________________________________________
class IndexView(generic.ListView):
template_name = 'polls/index.html'
#context_object_name = 'latest_poll_list'
# def get_queryset(self):
def get_context_data(**kwargs):
context = super(IndexView, self).get_context_data(**kwargs)
# Filter 1
filter_1 = Word.objects.filter(pub_date__lte=timezone.now()
