Custom Form Handling With Turbo. Turbo will be a default part of Rails…

Turbo will be a default part of Rails from Rails 7, replacing Turbolinks and rails-ujs. This post is a result of time I spent digging into Turbo, in particular its implications for forms that don’t seem to fit what Turbo is designed for: that is, forms that don’t necessarily (or only) trigger a redirect or DOM changes. I don’t have a definitive answer for what we should do in these cases, but I’ll explain some options that might be useful if or when Turbo’s constraints feel a bit awkward.
