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
import datetime
from django.db import models
from django.utils import timezone
# Create your models here.
class Question(models.Model):
question_text = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
def __str__(self):
return self.question_text
def was_published_recently(self):
now = timezone.now()
return now - datetime.timedelta(days=1) <= self.pub_date <= now
class Choice(models.Model):
question = models.ForeignKey(Question, on_delete=models.CASCADE)
choice_text = models.CharField(max_length=200)
votes = models.IntegerField(default=0)
def __str__(self):
return self.choice_text

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,DanielI'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?----
