Each installation of our Django site has slightly different settings -- namely, which database to use. Developers can provide a local_settings.py
file which lets them override (or, just as usefully, extend) settings that are in settings.py
.
Subversion is told to ignore local_settings.py
, so it's never checked in.
If local_settings.py
is missing, the site refuses to work.
We include a local_settings_example.py
file so that new developers can get started more quickly.
