I have a custom field type that I defined, and now I can't do a syncdb.
The relevant bits of the type are
class PyMongoField(models.CharField):
__metaclass__ = models.SubFieldBase
...
def db_type(self, connection):
return 'varchar(64)'
...
But I just get this when I do reset or syncdb on an app with a model that
uses that field type. Any clue?
