juhu, it works...
I have to admit after reading my initial post again I could habe been
more clear.
So here my example & test case which now works with Umapathy S
suggestion.
I created a model:
class Diameter(models.Model):
thickener_diameter = models.SmallIntegerField()
when I add a few diameters in the shell and then query them I get only
Diameter.objects.all()
[<Diameter: Diameter object>]
I then added
def __unicode__(self):
return self.thickener_diameter
to the model and when querying the Diameter I receive a
TypeError: coercing to Unicode: need string or buffer, int found
So I assumed it has something to do with that thickener diameter is
not a string
But when I use
def __unicode__(self):
return "%d" % self.question_number
it works! Thant you all ... as I said I'a quite a beginner :-)
