Any hints as to why this wasn't merged @westonganger?

[westonganger]

I remember creating this PR then sometime after thinking that possibly this library was not the cause. But honestly I just sort of learned to live with the Rails deprecations which however are extremely annoying.

If someone else can verify this code, this PR could be looked into again.

Thanks for the info. I was able to identify this as the culprit of a ton of deprecation warnings in our codebase (noticed in rspec test runs) with upgrade to Rails 5.1

I had implemented something similar but didn't have any luck keeping the tests passing locally so tabling for now.
