[LRUG] Multi page form design gem for Rails?

[Duncan Stuart]

I don’t know of a gem - it’s a recurring problem, and a fiddly one since the concept of state is different from standard Rails CRUD. 

We’ve used an approach of storing a hash of answers in the session: https://github.com/LBHackney-IT/maintain-my-home/blob/develop/app/models/selected_answer_store.rb , and elsewhere configuring the branching structure of a set of similar multiple-choice questions in YAML: https://github.com/LBHackney-IT/maintain-my-home/blob/develop/app/models/question_set.rb

This approach was borrowed from some gov.uk site (I forget which but you can find it in the commit history). Iirc that project additionaly had an object responsible for deciding what the next question should be, based on the previous answers. 

Good luck!
