Hi,
I am very new to Django, I have created multiple models in my app. I am using
postgresql_psycopg2 as my data base. When I run ./manage validate it returns
without errors, sqlall works fine and when I syncdb it works as expected, the
issue occurs when I run syncdb a second time I get the following errors:
$ ./manage.py syncdb
Creating tables ...
Traceback (most recent call last):

I have searched google and this list and have not been able to find any help.
Is there a limit on the amount of classes I cam specify in the models.py file?
Please let me know if you need any more information.
Thanks a lot
Cheers
John
