I don't think anything in my model has changed. I have reverted it back to times when it was all fully functional and I still get the following errors.
There are my models:
class UserProfile(models.Model):
# This line is required. Links UserProfile to a User model instance.
user = models.OneToOneField(User)
# The additional attributes we wish to include.
website = models.URLField(blank=True)
picture = models.ImageField(upload_to='profile_images', blank=True)
# Override the __unicode__() method to return out something meaningful!
def __unicode__(self):
return self.user.username
# Could create more post classes, or introduce foreign keys. Unsure as of now.
class Post(models.Model):
title = models.CharField(max_length = 140)
body = models.TextField()
date = models.DateTimeField(blank=True)
INTRODUCTION = 'I'
STORIES = 'S'
CATEGORY_CHOICES = (
(STORIES, 'Stories'), # Variable name and display value
(INTRODUCTION, 'Introduce Yourself'),
)
category = models.CharField(max_length=1,
choices=CATEGORY_CHOICES,
default=INTRODUCTION)
def __unicode__(self):
return self.title
class Photo(models.Model):
title = models.CharField(max_length = 140)
photo = models.ImageField(upload_to='user_images', blank=True, null=True)
date = models.DateTimeField(blank=True)
description = models.TextField()
def __unicode__(self):
return self.title
Upon running manage.py migrate I am confronted with the following error. Having checked the other answers, it seems it was something to do with datetime being used incorrectly but even if I remove date and the DateTime field altogether the error still persists. Does anyone have any ideas?
Thank very much for your help.

Here is 'blog.0007...' migration that seems to be failing. To clarify what is going on I was attempting to add a few attributes in order to tell who posted, and at what time etc. Clearly something is not going according to plan..
