multiple-models

Thanks for reading. I am using Devise and Rails 4. I want to add multiple User Models(admin, usertype1, usertype2) such that they inherit from the main User Model. I have searched many posts and come to the conclusion that I may use CanCan, which I do not want, or I may use Single Table Inheritance. The way I see it is to add a type string-column to my main User model I created with Devise. I will also need to extend each sub-class from the parent as in: class Admin < User end class Usertype1 < User end class Usertype2 < User end My question is: what do I do next? How exactly do I know how to

My nested model form is working great on the first level deep. But I was under the impression that you could go many levels deep using accepts_nested_attributes_for. But when I try the code below, the "Image" attributes are attached to the top level "Question" model and it breaks upon form submission with an unknown attribute "Image" error.

First, I've searched intensely with Google and Yahoo and I've found several replies on topics like mine, but they all don't really cover what I need to know. I've got several user models in my app, for now it's Customers, Designers, Retailers and it seems there are yet more to come. They all have different data stored in their tables and several areas on the site they're allowed to or not. So I figured to go the devise+CanCan way and to try my luck with polymorphic associations, so I got the following models setup: class User < AR belongs_to :loginable, :polymorphic => true end class Customer
