-# For users with login '*test_user*', we don't want to store these documents in
-# the main users db. This is because we create and destroy a lot of test
-# users. This weirdness of using a different db for some users breaks a lot of
-# things, such as associations. However, this is OK for now since we don't need
-# those for running the frequent nagios tests.
-#
-# This module is included in user.rb. This will only work if it is included
-# after designs are defined, otherwise, the design definition will overwrite
-# find_by_login().
