![]() It's an example of layered application architecture, and in MVC there are of course three layers. You understand the MVC architecture pattern. That said, I have a different idea to suggest on how multi-step forms could be handled. The Wicked gem is absolutely the best Rails multi-step form tool I could find, and it looks like a lot of care was taken to cross all the t's and dot all the i's. From the examples I've seen where people try to do it, things get yucky Partial object validation is hard, and there's also a bigger problemīefore you go on, please read (or at least scan) Building Partial Objects Step by Step in the Wicked gem wiki. This splitting of models across forms means you have to ask awkward questions like, "Hey, ActiveRecord, is the half of this object I have so far valid?" I don't think ActiveRecord was designed for validating parts of objects. (In reality you should maybe make a distinction between a user profile and a user account, but that's another matter.) What you have is a single model split across two forms. To avoid intimidating the user with a long form, you put email and password on the first page of your multi-step form and the rest of the fields on the second page. For example, let's say you have a user model with attributes email, password, first_name, last_name and homepage_url (all required). There is not necessarily a one-to-one relationship between a step in your multi-step form and a model in your application. Why are multi-step forms so hard? The main challenge seems to be validating partial objects. ![]() If there ever was a task that seemed straightforward from the outside, but then turned out to be really complicated when you got into it, a multi-step form is it.
