Comment (by sachinvettithanam):
No i am not faking it
This is what really happens in 1.8
i try migrate --fake-initial - it didnt work
Response:
It says Your models have changes that are not yet reflected in a
migration, and so won't be applied.
Run 'manage.py makemigrations' to make new migrations, and then re-run
'manage.py migrate' to apply them.
with the same bunch of contenttype errors
'''Only Solution i really found was Downgrading to 1.7.* and migrating
contenttypes individually'''
migrate contenttypes
Response will be the same
It says Your models have changes that are not yet reflected in a
migration, and so won't be applied.
Run 'manage.py makemigrations' to make new migrations, and then re-run
'manage.py migrate' to apply them.
but there wont be any errors and issue will be solves temporarily
Note: now we can goback to 1.8 and go on with the developments .
Migrations wont have any issue in 1.8 untill we add a new table(i didnt
find any issues with columns ). If we add new table we should again do the
same procedures .
