Re: using return upper
Hello,
I found a solution for the simplified version of my problem.
In models.py, I use:
def __unicode__(self):
oses_installed =
u','.join(self.operatingsystemused.all().values_list('operatingsystem',
flat=True))
return ("%s" % (oses_installed))
However, it doesn't works in admin.py
Following lines give me (None):
def renvoi_os(maintenance):
oses_installed =
u','.join(maintenance.ordi.operationsystemused_set.all().values_list('operatingsystem',flat=True))
return ("%s" % (oses_installed))
class MaintenanceAdmin(admin.ModelAdmin):
list_display = (renvoi_os,)
Thanks for your help

How about
self.operatingsystemused.all().values('operatingsystem',flat= True)

Re: using return upper
Hello,
I try to simplify the problem.
This model gives me a (None) result:
class OperatingSystem (models.Model):
operatingsystem = CharField (max_length=30, blank=True, null=True)
def __unicode__(self):
return "%s" % (self.operatingsystem)
class Ordi(models.Model):
architecture = CharField (max_length=30, blank=True, null=True)
operatingsystemused = ManyToManyField(OperatingSystem, null=True,
blank=True)
def __unicode__(self):
oses_installed =
u','.join(self.operationsystemused_set.all().values('operatingsystem',flat=True))
return ("%s" % (oses_installed)).upper()
Or also the same with that last line:
return models.join(list(self.operatingsystemused))
What can I do??
thanks

Re: using return upper
Hello,
With your stuff, it still shows me (None).
You are right, Ordi means Ordinateur (computer)

The function renvoi_os seems to take an 'Ordi' (ordinateur?) object,
but you have associated it with MaintenanceAdmin, which is associated
with Maintenance, not an Ordi, so the renvoi_os function will raise an
exception when you attempt to access the 'operatingsystemused'
attribute, which exists on Ordi instances, not Maintenance instances.
Further more, 'operatingsystemused' is not a simple attribute of Ordi,
its a ManyToMany, which you are trying to display as a decimal number
('%d' in your format string).
This should work:
def renvoi_os(maintenance):
oses_installed = u',
'.join(maintenance.ordi.operationsystemused_set.all().values('operatingsystem',
flat=True))
return ("%d %s" % (maintenance.ordi.id, oses_installed)).upper()
class MaintenanceAdmin(admin.ModelAdmin):
list_display = (renvoi_os,)
Cheers

using return upper
Hello,
I'm trying to modify my admin.py from my app "ordis":
from ordis.models import Ordi, Maintenance, OperatingSystem
from django.contrib import admin
#class MaintenanceAdmin(admin.ModelAdmin):
#list_display = (???) here I would like to see my Computer id, and
the OS installed on it
def renvoi_os(Ordi):
#return ("%d" % (Ordi.id)).upper()
return ("%d %d" % (Ordi.id, Ordi.operatingsystemused)).upper()
class MaintenanceAdmin(admin.ModelAdmin):
list_display = (renvoi_os,)
#class OrdiAdmin(admin.ModelAdmin):
admin.site.register(Ordi)
admin.site.register(Maintenance,MaintenanceAdmin)
admin.site.register(OperatingSystem)
That admin.py is associated with this models.py:
from django.db import models
from django.db.models import (Model, BooleanField,
CharField, DateTimeField, TextField, URLField,
EmailField, ManyToManyField, ForeignKey, IntegerField,
FileField, ImageField)
# Create your models here.
class OperatingSystem (models.Model):
operatingsystem = CharField (max_length=30, blank=True, null=True)
class Ordi(models.Model):
architecture = CharField (max_length=30, blank=True, null=True)
operatingsystemused = ManyToManyField(OperatingSystem, null=True,
blank=True)
class Maintenance(models.Model):
ordi=ForeignKey(Ordi, blank=True, null=True)
action = TextField(null=True, blank=True)
When I just call Ordi.id in admin.py (commented line), I get the Ordi
id associated with "Maintenance".
But the line with Ordi.id + Ordi.operatingsystemused gives me back a
(None)
What am I doing wrong??
THanks for your help
Florian
