POCreate a wizard that works with multiple Resources
text
Body
copied!<p>I'm writing an app that has a "wizard" type input section. Think MS Windows Installers.</p> <p>I'm having a hard time figuring out how the most RESTful way to do this with rails. I can make it happen in a non-restful way (already did for version 1 of the app), but I'm trying to be a little more idiomatic this time around.</p> <p>Here's the situation. I have a 5 step wizard that has to gather information. Steps 1, 2, and 4 deal with resource A. Step 3 deals with multiples of resource B and must associate them to resource A. Step 5 is just a confirmation.</p> <p>So I have my resourceA_controller and my resourceB_controller...but they only save/update that one resource. I'm guessing that I should set up a wizard_controller for each of the steps in the process, but I'm not sure how the routing should work.</p> <p>For example...</p> <pre><code>WizardController < ApplicationController def stepOne @resourceA = ResourceA.new end def stepTwo @resourceA = params[:id] end ... def stepFive end end </code></pre> <p>And then I would have my view be on the StepOne view:</p> <pre><code><form action='/resourceA/new'/> </code></pre> <p>and on the StepTwo action</p> <pre><code><form action='/resourceA/12345/edit'/> </code></pre> <p>etc.</p> <p>But then my resourceA and resourceB controllers would have to know how to redirect to the appropriate step in the wizard_controller. Tangled mess!</p> <p>Am I anywhere near the right track? Or is there a rails built-in mechanism or plugin that does this kind of thing.</p>
