# Mongoid inline relation definitions. Ruby makes it so easy.
# (`data` is effectively just a shortcut for `inline_embed_one(:data)` there.)
#
# Yes, it would make sense to create separate models, but my case is different.
# This application is used to track events of other apps, such as purchase, and
# it makes *more* sense to embed all order-related data. Instead of having model
# overload for each event being tracked, I just define them inline.
