This was more than 5 years ago… wow!
Sorry, I have absolutely no idea now. I would suspect that "yes," I got it
sorted, but I would anticipate that the internals of Django's ORM have
changed significantly since then, so even if I could remember how I did it,
it wouldn't be of much use…
Perhaps if
Hey!
I'm dealing with a similar issue.
Would you be able to tell me if you managed to solve this issue?
and if so, how?
Thanks!

Hi.
I've wrote a custom model field which splits strings by commas and
returns a list of values. Everything works fine except the admin -
after editing a record admin treats the custom fields as modified even
if they were actually not, issuing an UPDATE query for (not modified)
record and adding a
Hi,
I think what you're trying to accomplish is more or less what
django-tagging [http://code.google.com/p/django-tagging/] does, so I
suggest looking at its source code.
HTH,

Hi all,
I want to create my own "field" type for a model, this essentially
will be a relationship to another model via a generic link model
(using GenericForeignKey etc).
As en example I basically want to do the following in models.py:
class Pizza(models.Model):
toppings = IngredientsField()

Howdy Folks,
I have been testing model inheritance using models that have UUIDField
primary keys. It appears that when you save a new instance of a child
model, the framework is not calling get_db_prep_value() to convert the
UUIDField to a proper format before querying the parent entry.

Hi,
did you got any response or did you managed to solve your problem?
I've just started to search for a UUIDField, and it would be great to
have proper uuid columns for postgres.
If so do you plan to commit it to django_extensions?
Thanks, Viktor

I found the implementation done by the django_extensions project

OK, well now, for some reason whenever I use a custom field Django
just ignores it when running syncdb. If I ask it for the raw SQL
