I had already several times the situation that the unicode method of one of my models returned None in some case.
This leads to a "TypeError: coercing to Unicode: need string or buffer, NoneType found" traceback.
That's okay, but sometimes it is not easy to guess *which* model is wrong.
So I took django/db/models/base.py and added the lines marked '+' below:
def __repr__(self): try: u = unicode(self) except (UnicodeEncodeError, UnicodeDecodeError): u = '[Bad Unicode data]' + except TypeError,e: + raise TypeError("%s: %s" % (self.__class__, e)) return smart_str(u'<%s: %s>' % (self.__class__.__name__, u))
