Greetings,
I'm in the process of porting an application from Django v0.96 (using
Python 2.3) to v1.0 (using Python 2.4). I had been using
django.core.validators, but since that doesn't exist in v1.0 I'm
trying to replace the functionality with a custom field.
The code that I'm using is as follows:
#########################################
# app_utils/__init.py__
from django.db.models import CharField
class MacAddressField(CharField):
def __init__(self, *args, **kwargs):
kwargs['max_length'] = 17
super(MacAddressField, self).__init__(self, *args, **kwargs)
def db_type(self):
return 'varchar(17)'
#########################################
# other_equipment/models.py
from django.db import models
from app_utils import MacAddressField
class NetworkDevice(models.Model):
mac_address = MacAddressField('MAC Address', primary_key=True)
name = models.CharField(max_length=255)
ip_address = CharField('IP Address', max_length=15, null=True,
blank=True)
def __unicode__(self):
return u'%s' % (self.mac_address)
#########################################
# other_equipment/admin.py
from django.contrib import admin
from other_equipment.models import NetworkDevice
class NetworkDeviceAdmin(admin.ModelAdmin):
list_display = ('mac_address', 'name', 'ip_address',)
search_fields = ('mac_address', 'name', 'ip_address',)
admin.site.register(NetworkDevice, NetworkDeviceAdmin)
#########################################
The administrative interface for the model almost works... the problem
that I'm currently working on is that instead of the seeing "MAC
Address" as the mac_address label I see "<app_utils.MacAddressField
object at 0x9995c2c>".
Any clue as to what I'm doing wrong?
