The problem is actually not in the admin section, the culprit is __unicode__ method in your model. when you have a unicode function like this: def __unicode__(self): return “{0}”.format(self.field_one) It is actually returning… Read More »
I think it’s necessary to create a video to demonstrate how quickly web application development can be. Enjoy!
