Hi,
I've a problem with the Django admininterface on my productive server.
If I want add an object with the admininterface I get following error

I only get this message on my productive server. It runs with
mod_python, postgresql 8.1 and Django SVN Revison 5335.
The same revision is on my local pc. But I use postgresql 8.2 and
djangos internal server. On my local pc I don't get any errors.
My model looks like the following:
class Marke(models.Model):
name = models.CharField(maxlength=100)
bild = models.ImageField(upload_to='marken/', height_field='hoehe',
width_field='breite', blank = True, null=True)
class Optionen(models.Model):
name = models.CharField(maxlength=100)
class Optionswert(models.Model):
name = models.CharField(maxlength=100, core=True)
option = models.ForeignKey(Optionen, edit_inline=models.TABULAR,
num_in_admin=7, num_extra_on_change=4,)
class Rubrik(models.Model):
name = models.CharField(maxlength=100)
rubrik = models.ForeignKey('self', blank=True, null=True,
related_name="Elternrubrik")
bild = models.ImageField(upload_to='rubrik/', height_field='hoehe',
width_field='breite', blank = True, null=True)
class Artikel(models.Model):
MWST = (
(7 , 'Ermäßigt' ),
(19, 'normal'),
)
art_name = models.CharField(maxlength=100)
kurztext = models.CharField(maxlength=500)
beschreibung = models.TextField()
preis = models.FloatField()
mwst = models.IntegerField(choices=MWST)
optionen = models.ManyToManyField(Optionswert)
anzahl = models.IntegerField(blank=True, null=True)
rubrik = models.ForeignKey(Rubrik)
marke = models.ForeignKey(Marke)
def __str__(self):
return self.art_name
class Admin:
list_display=('art_name', 'rubrik', 'marke', 'preis')
list_filter=['marke', 'rubrik']
I got a similar message when I try to change users with
django.contrib.auth and again only on the server.
Create or change objects without the admin works fine. So I think its
a problem with the admin. But I don't know why I only have these bug
on the server and not local.
The error message is in these case:
KeyError at /admin/auth/user/1/
<type 'instance'>
Request Method: GET
Request URL: --MYSERVER--/admin/auth/user/1/
Exception Type: KeyError
Exception Value: <type 'instance'>
Exception Location: /usr/lib/python2.4/site-packages/django/utils/
functional.py in __wrapper__, line 43
Template error
In template /usr/lib/python2.4/site-packages/django/contrib/admin/
templates/admin/field_line.html, error at line 4
Ohh, i see that there is another different between server and my local
computer. I use python2.4 on serverside and 2.5 on my local
computer....
Hope you can help me....
Christian!
