While preparing for my presentation at RailsConf I decided to write an e-book on the same topic: creating an e-commerce site using Ruby on Rails. The result is The Money Train, a collection of tips for those who are interested in building their own shopping cart application using Ruby on Rails. The book is not a complete, step-by-step guide on building a storefront, but it does provide useful information for those at the beginning of the project from someone who has been there and done that.
Like the Beta Books from the Pragmatic Programmers or the Rough Cuts series from O'Reilly, I'm releasing this book before it is finished to help get this information out there sooner, and to give those who buy this early version a chance to guide the direction of the book with their feedback. I've provided some samples of the book so you can get a taste of what's in it before you buy.
I hope you enjoy it, and if you'll be at RailsConf be sure to stop by and let me know what you think!
Update: I forgot to mention this when I first made this post, but I want to thank Ben Wiseley for giving me the idea to write the book and helping me by reviewing it. I haven't had a chance to incorporate his suggestions yet, so don't blame him if you don't like the book. :)
