I'd like to propose adding a method to Model that can be used to fetch
a "fresh" version of a model object from the database. This is
something that I personally would often find useful. Usually this
happens when I'm testing some view code using the test client, and the
view is supposed to save some model changes into database. For
example:
client.post('some_url', {'id': obj.id, 'description': 'new'})
fresh_obj = ObjClass.objects.get(pk=obj.pk)
self.assertEqual('new', fresh_obj.description)
Now, I think that way of refreshing a model object is inelegant. What
I propose is a method that would be functionally identical to how a
fresh object is fetched above:
fresh_obj = obj.refetch()
This is a convenience method, but based on my own experience it would
be... well, convenient. I'd like to hear whether you think the
convenience would be worth extending the api. If you think it's worth
it, I'd be happy to write a patch.

Why not just make a custom model method?
This isn't a completely unreasonble idea, but it is an unreasonable
time to suggest it :-)
We are days away from our feature freeze for 1.2. At this point, any
new ideas will need to wait until 1.3.
I'm fairly certain this idea has been proposed before, so there's
probably a ticket for it, too. If there isn't, open a new ticket so we
don't forget the idea.
If you want to propose this for 1.3, keep an eye on the release
schedule; once 1.2 is released, we'll start discussing the features we
want in 1.3.
Yours,
Russ Magee %-)

I'm almost positive this is a dupe of another ticket, in the 3000-6000
range I think.

That one may be the one I'm thinking of (I've apparently seen it
before anyways), but I seem to recall one with a patch on it.
