Hi, I am new to Django (and python), and I have a question regarding
database query stuff

Basic info - I have a category model and an article model, and each
article is linked to a category through a foreign key

If i have the following code

---

category = Category.objects.all()[0]

return HttpResponse(cat.article_set.count())

--

Will that return the count of all of the articles in the given
category using a COUNT(*) query, or will it actually pull ALL of the
articles from the database and get the size of the array?

Basically i'm trying to figure out if im being efficient or just
downright wasteful :)

Thanks
