Part four, "Secure and Deploy Your Application," provides all the information on how to protect your application from SQL Injection and Session Fixation Attacks. It gives you tips on handling file uploads, storing sensitive information, and the use of SSL. It also shows you how to set up a production server, deploy your application, and how to monitor a deployed application.
The book finishes up with four appendices. The first, "Introduction to Ruby," will give you an overview of the Ruby language. Appendix B handles Rails configuration parameters. Appendix C contains the source code for the Depot application as well as the link to download the source code. The Final appendix contains online resources as well as the bibliography.
A couple of things I really like about the book and the publisher is that you can buy the book as a standard book as well as a PDF e-book. For a real discount you can get both. To me, this is a bonus since I like having the physical book to hold and read, but when I am working on something or traveling, I can still reference the material without locating the book. I also liked the detailed explanations contained in the footnotes. The authors do not try to overwhelm you with every detail in the dialog. Rather they are saying there is more information if you need it.
