As workaround I changed to this code in router:
def allow_syncdb(self, db, model):
"Make sure the auth app only appears on the 'geonames' db"
if db == 'geonames':
return model._meta.app_label == 'geonames' or \
model._meta.app_label == 'contenttypes' ##This is
the workaround
elif model._meta.app_label == 'geonames':
return False
return None
I want a separated geonames db, instead credentials db. But is
equivalent issue. It duplicates django_content_type table, but only
this.
I need execute syncdb on default database first.
Reggards,
