Are you sure your polls/models.py is correct?
I assume you are at „Part 2: Playing with the API". Here is what your polls/models.py should look like at this point of the tutorial:
My guess is that you have a typo in your __str__ method. This gets triggered in the first session because your Question had Choices, which it doesn't in your second session, maybe because you deleted them. But that's really just a guess without looking at your code.
I've put together the complete code for the tutorial, step-by-step:
Hope that helps,

I've made anything by site tutorial, just repeat all steps and code. And when I wrote this:-->>> from polls.models import Question, Choice# Make sure our __str__() addition worked. >>> Question.objects.all() <QuerySet [<Question: What's up?>]> # Django provides a rich database lookup API that's entirely driven by # keyword arguments. >>> Question.objects.filter(id=1) <QuerySet [<Question: What's up?>]> >>> Question.objects.filter(question_text__startswith='What') <QuerySet [<Question: What's up?>]> >>> from django.utils import timezone >>> current_year = timezone.now().year >>> Question.objects.get(pub_date__year=current_year) <Question: What's up?> >>> Question.objects.get(id=2) Traceback (most recent call last): ... DoesNotExist: Question matching query does not exist. >>> Question.objects.get(pk=1) <Question: What's up?> >>> q = Question.objects.get(pk=1) >>> q.was_published_recently() True >>> q = Question.objects.get(pk=1) >>> q.choice_set.all()Im getting 'Question' object has no attribute 'choice_text'.But then I have got some magic solution! I define if Im writting only this:>>>from polls.models import Choice, Question >>>from django.utils import timezone >>>q = Question.objects.get(pk=1) >>>q.choice_set.all() Out[4]: <QuerySet []>Then I dont have any problems, but I have done the same main steps then before(like in tutorial)! Sorry, but WTF is going on?
