Rails 3.2: A Nested-Form Demo, Part 1: All Wings Report In!

Jan 19, 2013   //   by Jeff Johnson   //   Blog  //  No Comments

Background

I’ve been working on a Rails 3.2 project for the last several months. While it’s been a blast to learn a new technology stack (I’ve spent most of my career working with .NET), there have definitely been some bumps in the road. In particular, I’ve spent the last couple weeks working on persisting a model that has a parent-child relationship. The bulk of that time was spent poking around the inter-webs, looking for tips and tricks to accomplish my goal. During my inter-web search, I couldn’t find a single post (or series of posts) that had a complete example or tutorial on how to persist a model that has a parent/child relationship. My Google-fu might not be as good as some other developers out there, but I searched pretty hard. What I found were bits and pieces scattered about (primarily on my savior, Stackoverflow). After a LOT of trial and error (mostly the latter), I finally have it working. So I thought I’d collect my notes as a series of posts. FYI -  this started as one post, but got WAY too long. Even for me.

Objective/Goals

Reading is real neat, and I do a whole lot of it. I tend to learn by doing, so reading only gets me halfway there. To that end, we’ll build a demo application that ultimately addresses the following:

  • Allows a user to save a model that has a parent/child relationship.
    • The operation will allow us to save the parent object as well as insert/update/delete new child objects that are associated to the parent.
