 In polls application I added annotation to check one to many relationship
 between Question and Choice models such that, Index only return questions
 with more than one choices to be displayed but my testcase fails all the
 time with annotation where both query returns same data.

 views.py (Not Working: Added annotate(num =
 Count('choice')).filter(num__gt=1))

 class IndexView(generic.ListView):
 template_name = 'polls/index.html'
 context_object_name = 'latest_question_list'

 def get_queryset(self):
     """Return the last five published questions."""
     return Question.objects.annotate(num =
 
Count('choice')).filter(num__gt=1).filter(pub___lte=timezone.now()).order_by('-pub_date')[:5]

 Error:

 Traceback (most recent call last): File
 "C:\Users\hmnsh\repos\DjangoApp\mysite\polls\tests.py", line 80, in
 test_past_question [''] File "C:\ProgramData\Anaconda3\envs\django\lib
 \site-packages\django\test\testcases.py", line 940, in assertQuerysetEqual
 return self.assertEqual(list(items), values, msg=msg) AssertionError:
 Lists differ: [] != ['']
