OneToOne edit_inline - can not add new object in Django admin

[alex@…]

Consider following code snipped (I tried to make it very simple just to explain this bug):

from django.db import models
from django.contrib.sites.models import Site


# Create your models here.

class Article(models.Model):
    title = models.CharField(maxlength=50)
    description = models.TextField()
    class Admin:
        pass
    
class CustomArticle(models.Model):
    fti_contents_list = models.TextField(null=True, blank=True)
    layout = models.CharField(maxlength=1,core=True)
    sites = models.ManyToManyField(Site,core=True)
    article = models.OneToOneField(Article,edit_inline=True)

Here I use OneToOne field to extend standard Article application with custom data I need to use with particular
customer.

The problem:

When I add new product in /admin it fails with error:

File "/usr/lib/python2.4/site-packages/django/db/models/related.py", line 71,

in get_list

if self.field.rel.min_num_in_admin:

AttributeError: 'OneToOneRel' object has no attribute 'min_num_in_admin'

The solution: see attached patch

Thanks for the patch, alex. We know that edit_inline has lots of problems (e.g. ​http://code.djangoproject.com/wiki/FeatureGrouping#edit_inlineIssues), but the new admin changes that will be coming after the 0.96 release should clear this up.

Because of this, I'm marking this as invalid for now, but I've placed it on the FeatureGrouping page, and we'll double check that it's no longer an issue once these changes have gone through.

Thanks Simon! I also listed another my bug on almost same combination but on Edit (3188) in this Wike page. Personally I think issues must stay open until they are either fixed or deprecated (as newadmin comes) but lets discuss this out of bug tracking system. I will post my suggestion on django-developers list.

I keep getting customer complaints about my software.
Installing my patch everywhere helps but its difficult to maintain this.

Reopened, see discussion ​here

This isn't ready for checkin. We aren't applying any patches to existing admin because it will soon be replaced. So we need to wait for the support work to go into newforms-admin and then write a patch against that.

[Thomas Güttler <hv@…>]

This patch is necessary and works. Please commit. As long as newforms-admin is not stable,
support for (old) admin must be continued.
