Question

I'm trying the tutorial given on Django site. When I'm trying to run below command I'm getting error.

q = Question.objects.get(pk=1)
q.choice_set.all()
Traceback (most recent call last):

    raise AppRegistryNotReady("Models aren't loaded yet.")
AppRegistryNotReady: Models aren't loaded yet.

This is my models.py

from django.db import models
from django.utils import timezone
import datetime

class Question(models.Model):

    question_text = models.CharField(max_length=200)
    pub_date = models.DateTimeField('date published')

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

    def __unicode__(self):              # __unicode__ on Python 2
        return u'%s'%self.question_text

class Choice(models.Model):
    question = models.ForeignKey(Question)
    choice_text = models.CharField(max_length=200)
    votes = models.IntegerField(default=0)

    def __unicode__(self):              # __unicode__ on Python 2
        return u'%s'%self.question_text

This is my manage.py code

#!/usr/bin/env python
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "demo.settings")

    from django.core.management import execute_from_command_line

    execute_from_command_line(sys.argv)

This is my wsgi file

"""
WSGI config for demo project.

It exposes the WSGI callable as a module-level variable named ``application``.

For more information on this file, see
https://docs.djangoproject.com/en/1.8/howto/deployment/wsgi/
"""

import os

from django.core.wsgi import get_wsgi_application

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "demo.settings")

application = get_wsgi_application()

I'm not sure what I'm doing wrong over here. I followed the tutorial, but it is breaking over here.

I'm using python 2.7.9 and Django 1.8.2
