SQL-level joins happen automatically when required. You specify your
queryset in terms of filter() and exclude() calls and Django works out
which tables are needed to compute that result. Links between models are
specified using the double-underscore notation. Thus, "foo__bar" means
to use the "foo" field on the current model (a link to a related model)
and follow that to the "bar" field on the other end of the relation.
