Emily's suggestion of renaming your ForeignKey to LocationType is a good one. If you want to follow more well-defined conventions while coding in Python look at PEP 8 here: http://www.python.org/dev/peps/pep-0008/ Adding __unicode__ or __str__ methods to your location_type class is not sufficient for the above to work because the + operator can not be used in this way where location_type is not a string. Here are ways that would work: retval = unicode(self.location_type) + ' - ' retval = '%s-' % self.location_type For these two snippets to work 'correctly', you should define __unicode__ on your location_type model class. The two snippets above will still work without this method, but you will get Python's internal representation of location_type. For a better understanding of this look at __repr__, __str__, and __unicode__ here: http://docs.python.org/ref/customization.html --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
