'Question' object has no attribute 'choice_text'

[Artem Tantsura]

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?

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:

https://github.com/consideratecode/django-tutorial-step-by-step/blob/2.0/2.4/mysite/polls/models.py

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,

Daniel

Hi Rishi,

Hi Daniel,

Thank you for getting back to me.

Please find models as follows

Need all_Questions and all_Choices to reflect for each other.

I was reading MDN docs on django they recommend ManyToManyField. 

Please advise.

Thank You

Rishipal
