Error: Form responses must redirect to another location

[blaiseAI]

Hi Matt, QQ. Just added devise in my rails app. Only changes added was to add devise and it's views. it usually sets a message on the flash[:notice] that a confirmation email has been delivered or failed. I have not added any custom behavior. It's a barebones Rails app with Devise added by following the instructions on GitHub.

I think this is a known problem with Devise and Rails 7 + Turbo. The workarounds are:

• Remove Turbo from your app entirely, or
• Customize the Devise views data: { turbo: false } to the forms, or
• Customize the Devise controllers to fix their redirect behavior

In my recent project I did a combination of the 2nd and 3rd options.
