I have registration form , once I have submit that form , I was getting some response. I want to show same response on view action. Currently, I have registration page which have two tabs, one is for registration form and other is for post register activity form.where second tab is disabled till I have submitted the registration form. I am able to submit a form and getting response as well, now I want show same response on view action, How should I achieve that in rails web project ? How should my routes work in that case ?
