Description
Using this model:
class Product(meta.Model):
travelCode = meta.CharField('Reiscode', maxlength=7, primary_key=True)
class Unit(meta.Model):
travelCode = meta.ForeignKey(Product)
def repr(self):
return "%s %s" % (self.get_travelCode(), self.nonexistentfield)
class META:
admin = meta.Admin()
Displaying Unit in the admin interface works for the Unit overview, even though self.nonexistentfield does not exist. When one selects an entry for editting, Django throws the following TemplateSyntaxError:

raise wrapped
TemplateSyntaxError: Caught an exception while rendering.
On the front end a similar error is thrown when one tries to use the model object's representation. The error is especially unclear because it refers to a Template error while this essentially is a model error. A model exception stating that the model does not contain such a field would be nicer.
