'''Django's default behavior is "like" auto commit.
From Django docs, "Managing database transactions":
Django's default behavior is to run with an open
transaction which it commits automatically when any
built-in, data-altering model function is called. For
example, if you call model.save() or model.delete(),
the change will be committed immediately.
This is much like the auto-commit setting for most
databases.
Note the "much like" phrase. Initially, I thought they
meant you should turn on autocommit on the database
connection, but that didn't work. They mean that
internally Django has code to mimic autocommit.
