Chapter 6 of the Rails Tutorial, 2nd Edition is out ("Modeling users")

Jan 27, 2012 • posted by Michael Hartl

This is an update on the progress of the Ruby on Rails Tutorial, 2nd Edition. A draft of Chapter 6, "Modeling users", is now available. It covers the creation of a full User model, including secure passwords via the awesome has_secure_password method (new as of Rails 3.1). Various bugs in the first five chapters have also been fixed; thanks to all the readers who submitted reports. As before, please send any feedback to [email protected], and leave comments at Hacker News. To learn more about the Ruby on Rails Tutorial, 2nd Edition, see the original announcement.

I’m Michael Hartl—author, educator, and entrepreneur. I’m probably best known as the creator of the Ruby on Rails Tutorial, a book and screencast series that together constitute one of the leading introductions to web development. Once called his “favorite book” by Wikipedia founder Jimmy Wales, the Ruby on Rails Tutorial currently has over 150 5-star reviews at Amazon. I’m also (in)famous for creating Tau Day and The Tau Manifesto, which have inspired an international movement dedicated to the proposition that “pi is wrong.” (For example, as a result of The Tau Manifesto, MIT releases their admissions decisions each year at “Tau Time” (6:28 p.m.), and typing tau/2 at Google yields 3.14159…) Finally, I’m a founder of Softcover, a publishing system and sales platform for technical authors, which among other things powers both The Tau Manifesto and the Ruby on Rails Tutorial.

I’m a graduate of Harvard College and have a Ph.D. in Physics from Caltech, where I studied black hole dynamics and was an award-winning instructor in theoretical and computational physics. I’m also an alumnus of Y Combinator, the entrepreneur program that has produced companies such as Dropbox and Airbnb. (Alas, my own Y Combinator startup was neither Dropbox nor Airbnb.)
