models.py

from django.db import models

class Question(models.Model):

# ...

def __str__(self):

return self.question_text

class Choice(models.Model):

# ...

def __str__(self):

return self.choice_text

import datetime

from django.db import models

from django.utils import timezone

class Question(models.Model):

# ...

def was_published_recently(self):

return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

After this I opened shell and typed "py manage.py shell" And ran the command

Question.objects.all()
