Re: Model - def __unicode__(self) - doesn't work

Thank you a lot!

James & Tundebabzy - Thanks:)

It was the mistake.

Try changing the 'name' argument to 'verbose_name' like so:

name = models.CharField(max_length=30, verbose_name='Vlan name')

I don't believe model fields accept 'name' as a keyword arg. This would also explain the slightly confusing error due to the overlap of 'name' appearing in multiple spots.

So to be more clearly, let create new django project with one application for example with name networks.

Add those lines to the networks/models.py:

class Vlan(models.Model):

    name = models.CharField(max_length=30, name='Vlan name')

    def __unicode__(self):

        return self.name

add those two lines to networks/admin.py

from .models import *

admin.site.register(Vlan)

It should be (and was) enough to run admin interface. Unfortunately when I'm trying to add new vlan or list current vlans I get:

Look this is code from first part of official django tutorial.

When I delete def __unicode__(self) method from models file, it works fine but in vlan list I get Vlan object, Vlan object.... etc instead of names.

Hello guys,

I'm really beginner in django.

I have extremely simple example:

class Vlan(models.Model):

    name = models.CharField(max_length=30, name='Vlan name')

    number = models.IntegerField(default=0, name='Vlan number')

    def __unicode__(self):

        return self.name

When I'm trying to use admin interface, I got this error:

AttributeError at /admin/networks/vlan/add/

'Vlan' object has no attribute 'name'

Request Method:	POST
Request URL:	http://127.0.0.1:8000/admin/networks/vlan/add/
Django Version:	1.6.6
Exception Type:	AttributeError
Exception Value:	'Vlan' object has no attribute 'name'
Exception Location:	D:\Scripts\Mercury\networks\models.py in __str__, line 10
Python Executable:	C:\Python\Main\Scripts\python.exe
Python Version:	2.7.8

I'm sure that it was working a few days ago. And in meantime I did django upgrade.

What I'm doing wrong, and how I can fix it?

Thanks in advance.

Przemek.
