using relationship fields in ModelAdmin

I have an object in my model that has a OneToOne relationship with an object in another app. I would like to customize the way my object is displayed in the admin interface by subclassing ModelAdmin as shown in the tutorial. I'm not sure how to reference fields across the OneToOne relationship -

Re: Order model objects by foreign key "set" count

Ah - yes, that is so awesome! For anyone interested, here's the magic incantation: Book.objects.annotate(Count('reader')).order_by('reader__count') Or more verbosely: Book.objects.annotate(num_readers=Count('reader')).order_by ('num_readers') That documentation link describes it very well.

Since you asked for comments: The Django core developers are looking to discontinue Python 2.3 support soon, so it's a good idea to recommend 2.4 as the minimum, or state which version of Django requires Python 2.3 or higher. Just a personal preference, but I wouldn't recommend downloading and

Sure, but the transaction is still open and PostgresSQL prevents any other statements form being executed until it is closed. So, the db is pretty much locked until the next transaction is started (which in my case is when i render the view). I filed a bug for it:

Tim, I think that if you replace the term "namespace" with "group," we can do what we both want with the same solution. Or, in other words, we're kind of saying the same thing but using different words. In my scenario, each user would be in one or more groups. Each user could read or write

Thanks a lot - I didn't know about generic relations, and will definitely look at them - right now :). The minimal subset - and that's where I'm trying to follow DRY - boils down to a Title, a slug, Content HTML of the entry, maybe a couple more things - all are very much like what you would
