"The key to inheritance is to abstract functionality."
I realize we're not talking about inheritance, but I think it still
applies.
It may make logical sense that a user object has a blog that has
entries,
There's a pattern I keep running into, and I've been wondering if
anyone who's encountered it before has an opinion on how best to deal
with it:
Imagine you have an app that could theoretically stand on its own --
for now let's say a schedule, but it could be anything (an image
gallery, a blog, e
The user model, because the model defined by AUTH_PROFILE_MODULE is
intended to be an extension to the actual user model. Namely the
profile.
Why would you bind something to a user's profile, instead of the user
itsself? If you want to "allow records of people without Users", then
use blank=True
I`d go with the first. It`s easier to get the current logged in user and all
other pluggable apps use User, so it's a common thing to do and you can
integrate things easily .

I'm still making my first site with django so I don't how much weight my
opinion has, but I used a seperate profile for ForeignKeys. I don't know
why, it just seemed logical at the time. It is easer as you can refer to
whats in a users profile easier. You can put things like {{

Hi all!
While reevaluating my own historically old models I came to a dilemma
to which model it is better to set the ForeignKey when you want to
define ManyToOne relationship to a person. Should the ForeignKey point
to django.contrib.auth.models.User or to the one which is defined in
AUTH_PROFILE
Validation turns out to be well-nigh impossible using parent / child
aliases, but pretty easy with parent / child accounts. Here's what
I've ended up with:
class Account(models.Model):
user = models.ForeignKey(User, unique=True, null=True, blank=True)
alias = models.CharField(ma
I'm not asking as a Django / foreign key thing. I'm having a lot of
trouble referencing each model from the other's save method for
validation purposes, because there's always going to be one that's
declared after the other.

You can, it just creates headaches. At least one of the ForeignKeys needs to
not be required (I believe that's the default anyway).
