Новичек в django, вроде все окей но когда дело доходит до тестов то у меня появляются вопросы насчет того что я не так сделал, в каком-то коде или не правильно начал делать. P.S. Будет много кодов, но все равно надеюсь на вашу помощь

return render(request, 'polls/detail.html', context)
except ProductNotFound:
errors = "По запросу " + form.cleaned_data['query_name'] + " ничего не найдено"
return render(request, 'polls/detail.html', {'errors': errors})

вот ошибка которую он мне говорит:
File "/home/rahat/PycharmProjects/untitled1/venv/lib/python3.6/site-packages/django/db/models/base.py", line 115, in __new__
"INSTALLED_APPS." % (module, name)
RuntimeError: Model class products-aggregator.mysite.polls.models.Query doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.
На всякий случай вот мой handler
