Hello,
I'm trying to make my own validator which require access to models:
class Network(Model):
city =
CharField('Miejscowosc',maxlength=128,default='Bialystok')
description = CharField('Opis',maxlength=128)
network_ip = IPAddressField(unique=True)
network_prefix = CharField(maxlength=2)
router = IPAddressField(validator_list=[is_inside_network])
notice = TextField('Uwagi',blank=True,null=True)
class Host(Model):
ip = IPAddressField(unique=True)
#ip = IPAddressField(unique=True)
hostname = CharField('Nazwa hosta',maxlength=128)
description = CharField('Opis',maxlength=255,blank=True,null=True)
network = ForeignKey(Network)
hwaddr = CharField('MAC',maxlength=17,blank=True)
notice = TextField('Uwagi',blank=True,null=True)
When user adds host I'm trying to check if he choose proper network
using such validator:
# import above models
from wfs.hnm.models import *
def is_inside_chosen_network(field_data,all_data):
host_network=Network.objects.get(id=all_data['network'])
host_network_ip=host_network.network_ip
host_network_prefix=host_network.network_prefix
s=ipaddr.ip_set()
s.add_network(ipaddr.network(host_network_ip,int(host_network_prefix)))
if not s.contains(field_data):
raise validators.ValidationError("Adres IP host nie nalezy do
wybranej sieci - popraw siec lub adres IP")
Here is error I'm getting:
n [6]: is_inside_chosen_network("89.161.0.2",{})
---------------------------------------------------------------------------
exceptions.NameError Traceback (most

34 host_network_ip=host_network.network_ip
35 host_network_prefix=host_network.network_prefix
NameError: global name 'Network' is not defined
It's seems like some loop :) - how to solve this ?
Thanks for attention :)
