We're now ready for Rails 5.1. All deps we need have releases compatible with rails 5.1 🎉

I'll update this PR to also be compatible with rails 5.0. EDIT: Will add rails 5.0 compatibility back later instead (if possible)

This all looks quite sensible. 💯

Is it worth updating all form tags to use the new form_with? http://edgeguides.rubyonrails.org/5_1_release_notes.html#unification-of-form-for-and-form-tag-into-form-with. I know the Rails core team haven't said anything about deprecating current form tags but this is the unification of the two.

[jarednorman]

I can't imagine it's worth the effort of doing that up front if the existing helpers aren't being deprecated.

[ericsaupe]

@jarednorman that's what I thought as well. Just thought I'd bring it up!

[mamhoff]

Yay!
