Foreign key constraints not created

[philipn]

For some reason, foreign key constraints seem to not be created. I'm guessing this is because contribute_to_class() doesn't create a constraint? Not sure what's going on, as indexes and other stuff is created correctly. This is on Django 1.5.

I haven't had much time to investigate this further, but the following got me up and running with working constraints:

Using south, add follow as an external migration:

SOUTH_MIGRATION_MODULES = {
    'follow': 'utils.external_migrations.follow',  # My local migrations for external apps
}

Then create an initial migration and migrate:

manage.py schemamigration --initial follow manage.py migrate follow

and rinse & repeat for new fields.
