Django join promotion
View join_promotion
=========================
Join promotion in the ORM
=========================
[NOTE: We need better terms than promote and demote for changing the join
type. These terms are extremely easy to mix up. Maybe the ORM methods could
be to_inner_joins and to_louter_joins instead of promote_joins and demote_joins?
I tried to clean up the mis-usages of promotion/demotion but there could still
be some cases where these are mixed up]
