Hi Matt

Thank you very much for Your reply and effort to manage this issue.
It's pitty, that nested lists are not implemented in django.
I'll look Your diffs on http://pastie.org/823968 and try to do something.

Best regards
Ogi

Oh, and it is not flawless, there were still some issues I didn't get
sorted out. I had some validation errors of some sort, I think, when
updating data under certain circumstances, but I never quite
completely tracked it down.

Sounds like you want nested inlines. There is no built-in way to do
this with django. I did some work (and got a solution working), but it
required significant change to the installed django. I was planning on
trying to make it into an installable app, but didn't get far.

I do have a diff: I've just put it at http://pastie.org/823968 - this
is with a fairly old trunk though, so it may not merge back in that
well right now.

It was based on another nested-inline diff I had come across, but I
don't seem to have the link any more.

Matt.

InlineModelAdmin related items on two levels

[Ogi Vranesic]

Hi all

I read the very good tutorial on 
http://docs.djangoproject.com/en/dev/ref/contrib/admin/
and understood that the admin interface has the ability to edit models on the 
same page as a parent model and these are called inlines. For two related 
models is this easy:

class A (models.Model):
   name =...

class B(models.Model):
   a = models.ForeignKey(A)
   title = ...

in admin.py:

class B(admin.TabularInline):
model = B

class AAdmin(admin.ModelAdmin):
inlines = [
B,
]

and the result ist, that in add/change of A we can also add/change its child 
models B

My Problem is   that I however by B model have also child models: 
class C
  b = models.ForeignKey(B)
  name = ...

My Question is : 
Is it possible than one can add/edit models of A on the one page together with 
child models B and C as child models of B.

Any hint or idee would be very appreciated
Ogi
