I am unable to run command runserver in my django app. It always show: You have unapplied migrations; your app may not work properly until they are applied. Run 'python manage.py migrate' to apply them.
And when i am trying to migrate it will show this error: raise ValueError('The database backend does not accept 0 as a ' ValueError: The database backend does not accept 0 as a value for AutoField.
And this is the code in my models.py
class Category(models.Model):
category_name = models.CharField(max_length=128, unique=True)
category_alias = models.CharField(max_length=128, unique=True)
category_desc = models.TextField()
def __str__(self):
return self.category_name
class Question(models.Model):
#user = models.ForeignKey(User)
category = models.ForeignKey(Category)
question_text = models.CharField(max_length=200)
pub_date = models.DateTimeField('date published')
def __str__(self):
return self.question_text
class Answer(models.Model):
question = models.ForeignKey(Question)
answer = models.TextField()
def __str__(self):
return self.answer
class UserProfile(models.Model):
user = models.OneToOneField(User)
state = models.CharField(max_length=200, blank=True)
country = models.CharField(max_length=200, blank=True)
zipcode = models.CharField(max_length=200, blank=True)
def __str__(self):
return self.user.username
Can someone help me to come out of it.
Code in file 0003_question_user.py:
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.db import models, migrations
from django.conf import settings
class Migration(migrations.Migration):
dependencies = [
migrations.swappable_dependency(settings.AUTH_USER_MODEL),
('confession', '0002_userprofile'),
]
operations = [
migrations.AddField(
model_name='question',
name='user',
field=models.ForeignKey(default=0, to=settings.AUTH_USER_MODEL),
preserve_default=False,
),
]
#user = models.ForeignKey(User)
is commented now. Did you try to execute migrate while it was uncommented ?
try python manage.py migrate --fake and then
python manage.py migrate
