ValueError: too many values to unpack during migrate

[tubaman]

On step 2.5 of http://dkerwin.github.com/django-pki/installation/configuration.html, when running migrate I'm getting this error:

(myproject_pinax)pkiplayground@pkiplayground:~/sandboxes/myproject/server2 [master]$ ./manage.py migrate

Thanks for reporting this. I'll have a look at your issue asap. Thanks!

This is a pretty easy one.

@Tegereo just stumbled upon this when using depends_on, and it would have been clearer if it was stated that you need an extra comma to indicate it's a pack of tuples:

doesn't work, shows that 'too many values to unpack' error:

(
    ('myapp', '0001')  # no comma
)

works correctly:

(
    ('myapp', '0001'),  # has comma
)
