=========================
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]

Upgrade Django from 1.1 to 1.5.1. This highlights some of the issues that one may encounter when updating Django. It's not possible to cover every case, but this should provide a good general starting point.

Change to DATABASES variable in settings.py.

Django now supports multiple databases and changes are needed to how the database connections are defined.

• Changed in Django 1.2
• Change Required by Django 1.4

set -g prefix C-a

# Double tap to go to previous window
bind C-a last-window

# Splitting windows should use | and -
unbind %
bind | split-window -h
bind - split-window -v
