I am migrating from Django 1.6.5 to Django 1.8.4 I was using South for migrations in 1.6.5 and I followed the instructions here for removing South and using Djangos inbuilt migrations https://docs.djangoproject.com/en/1.8/topics/migrations/#upgrading-from-south
I have a custom user model in accounts.models as:
class User(AbstractUser):
"""
Model extends auth.user and stores more information like city, about me, location etc
"""
I created a new virtualenv in my local machine (mac) and installed Django 1.8 and upgraded all the other required packages, and removed South. The tests ran fine. Interesting, when I did
python manage.py makemigrations it creates two new files in the auth app in Django's own folder : .virtualenvs/dj18/lib/python2.7/site-packages/django/contrib/auth/migrations/
This migration works fine locally post that, however, when I commit these migration files (i.e. my own migration files without the auth migrations) into git, and deploy to my production server via fabric and do pip install Django==1.8.4 (full requirements.txt below), the installed Django folders do not have these two new files
[X] 0007_customuser_extensionuser
[X] 0008_auto_20150831_2031
and hence my python manage.py migrate shows errors

I printed out all the migrations from showmigrations after they were applied, so ignore the check boxes (X) to the left of these, just after doing makemigrations the checkboxes should be unchecked
