Thank you for making this!

Unfortunately, in Rails 5 this seems to be no longer working. I have not yet found out what has to be changed to fix it.

@Qqwy thanks but I haven't used Rails in many year so I cannot say how to adapt to the current iteration of the framework. Sorry!

No worries. If I find out, I'll tell you. And in the meantime: good luck with Lumen! 🙂

I believe that the slightly different version that is part of easy_auth still works correctly.
