Hello all, I've been working with Ruby on Rails for a few weeks now. It's difficult for me because I don't have much experience with Ruby, Rails, MySQL, or any other web-languages. But I'm trudging on and learning a lot. I've been working on a web application for my dad's website; it's a simple content manager for "listings." Using the scaffolding and other stuff I've learned I was able to set up the basic system easily, but the categories are not so simple. Categories are a model: they habtm (has_and_belong_to_many) listings, and listings habtm categories. This way an individual listing can display its categories, and a category can display its listings. Categories are also trees: each major category contains a variety of sub-categories. The difficult part is creating the UI to create a listing: a listing can have one or two main categories, and one or more sub-categories within those main categories. The UI needs to be user-friendly, as clients are going to be creating the listings. I've tried everything that I've learned about FormHelpers, but I don't think they can do what I want. So now I'm assuming that I'm going to have to write a bunch of Ruby code that creates a "select" form but more complex. I'm hoping to get something that looks like this (only prettier, and with meaningful categories): Categories: Monkeys Lions Elephants Click on Lions, it changes color to indicate selection, and the page changes to this: Monkeys Lions Taming Feeding Breeding Elephants Click on a sub-category and it lights up. Send the form (which will also include normal text fields) and the selected categories are added to the data. I'm not really looking for code here; I learn a lot when I do things myself. What I'm interested is some sort of idea of how to get started, what new tools I'll need to understand, and so on.
