While I was happy with django's db api, to an extent, it did not have
everything needed for the basics. So here is a quick solution to some
related fields using select_related().
It adds to parameters to select_related(), depth, and fields.
depth: A numerical field and represents the recursion depth for keys, by
default, django recurses infinitely on any keys that are not blank=True
fields: A list of field names in the base model to join with. It does not
support children, ie relatedfield__fieldname, but I'd like to add this
later, this will also set depth to 1.
I've done several unit tests (several being all of curse-gaming.com) and
we're pushing the changes live on the site now. It's helping performance
out quite a bit in areas where it was too difficult to manually join with
just one other table, or areas where we just wanted top level results.
