Polyamorous is merged into Ransack since Squeel and MetaSearch is not maintained anymore.
Polyamorous is an extraction of shared code from the Active Record Hackery gems Ransack, Squeel and MetaSearch by Ernie Miller and maintained by Ryan Bigg, Xiang Li, Jon Atack, Sean Carroll and a great little group of [contributors] (https://github.com/activerecord-hackery/polyamorous/graphs/contributors).
It is an internal library for extending various versions of Active Record with
polymorphism. There is no public API, so it's :nodoc:. Move along. Nothing to
see here.
