but that feels like cheating.. besides, I'd like to better understand
the ORM.
Ah... You mean "all tags that have relation to any blog". This is it:
Tag.objects.filter(blog__id__isnull=False)
This is less hackish than row SQL :-). Reference to 'blog' effectively
joins Tags and Blogs. id__isnull=False is a bogus condition that is
always true and is needed only to satisfy syntax. There is no such
explicit thing as "just join" in Django's ORM. Though given that I'm
writing this a second time for the last month may be it should :-)
