I saw your avatar yesterday night trying to fix this issue. 😂

Do you think that the monkey patch it's worth it? Why don't we use this limitation instead to force us to upgrade Rails? What do you think?

😂 not really fixing it last night, but got the Travis 🛑 email and I remembered that just recently I was fixing those problems in some gems...

IMHO yes, it's worth it! It's an "small" patch that not affects runtime, only controller tests. Since we are going to do a Ruby upgrade and test/review all app... why not? It doesn't force us to upgrade Rails right now either, and anyway, we should start to think in a Rails upgrade, our current version 4.2.Z is almost out of "Severe Security Issues" (Rails 6 is in rc already).

That's my point, we have to upgrade Rails ASAP. And that will bring latest Ruby with it.

OK then, let's do this! Thanks for your help as always 💪❤️
