(Django 1.3) coercing to Unicode: need string or buffer, int found

Posted 13 September 2012 - 11:55 AM

I'm pretty new with Django, so this is probably just a stupid mistake or something I'm not seeing that I should. I'm using version 1.3 and I'm having this issue: I created a model but when I add a score through the admin site it throws this error and I can't figure out why.

Traceback
Environment:


Request Method: POST

Solved.

I went to ask the question on #django on the freenode irc servers and FunkyBob told me this:

[06:12:59] <FunkyBob> your issue most likely stems from a __unicode__ method on one of your models
[06:13:10] <FunkyBob> it's returning a number... it must return a unicode obj
[06:15:04] <FunkyBob> your Score model... have it return unicode(self.score) instead

and it worked.
