I'm trying to make a single choice quiz (i.e. Choose one from 4 options).
I'll populate the quiz (with 30 questions) depending upon what topic the
user chooses. I'm made some models and forms, but when I try to migrate it
says
AttributeError: 'CharField' object has no attribute 'model'
I don't even know which model has problem. I've tried it in Django 1.9
(with virtualenv) & 1.8, same error. I've tried both manage.py check &
manage.py runserver and they all come up ok (with runserver saying I need
to migrate).
Python 2.7
Windows 7
Below are my models. Tell me if you require anything else. It's only
partially made and I've taken long-cuts in many things, 1st I've to make
the thing work.
from django.db import models
from django.template.defaultfilters import slugify
from django.conf import settings
from django.contrib.auth.models import User
class UserProfile(models.Model):
user = models.OneToOneField(settings.AUTH_USER_MODEL)
topic = models.CharField(max_length=50, blank=True)
def __unicode__(self):
return self.user.username
class Subject(models.Model):
subject_name = models.CharField(max_length=50)
def __unicode__(self):
return self.subject_name
class QuestionAnswer(models.Model):
subject = models.ManyToManyField(Subject)
question_text = models.TextField(max_length=150)
option_w = models.CharField(max_length=75, blank=True, null=True)
option_x = models.CharField(max_length=75, blank=True, null=True)
option_y = models.CharField(max_length=75, blank=True)
option_z = models.CharField(max_length=75, blank=True)
correct_answer = models.CharField(max_length=75, blank=False, default=None)
on = models.BooleanField(default=True)
def __unicode__(self):
return self.id
class Meta:
app_label = 'QuestionAnswer'
verbose_name='Question'
verbose_name_plural = 'Questions'
class QuizAttempt(models.Model):
username = models.ManyToManyField(User)
subject = models.ManyToManyField(Subject)
slug = models.SlugField(unique=False)
datetime = models.DateTimeField(auto_now_add=True)
questions_included = models.ForeignKey(models.QuestionAnswer)
correctly_answered_questions = models.IntegerField()
total_marks = models.IntegerField()
class Meta:
verbose_name='Quiz'
verbose_name_plural = 'Quizzes'
def save(self, *args, **kwargs):
self.slug = slugify(self.username +' ' + self.subject + ' ' + self.
datetime.month +' ' + self.datetime.year)
super(QuizAttempt, self).save(*args, **kwargs)
@property
def correct_answer_count(self):
return self._correct_answer_count
def __unicode__(self):
return "Quiz ID is {}".format(self.id)
return "The quiz was taken by {} on {}".format(self.username, self.topic)
return "The quiz was taken on {}".format(self.datetime)
