Chapter 6 of the Ruby on Rails Tutorial book

Feb 1, 2010 • posted by Michael Hartl

A draft of Chapter 6 of the Ruby on Rails Tutorial book is out. Enjoy!

By the way, Rails 3 is due out any day now; as soon as I verify that all the book (and gem/plugin) code works, I'll convert the tutorial over to use Rails 3, and future chapters should be Rails 3–compatible from the start. (The switch to Rails 3 will temporarily break the Heroku deploys in the tutorial, but worry not—they are hard at work and will be supporting Rails 3 soon.) For current readers, the Rails 3 switch will probably mean working quickly through the tutorial a second time to update your code; I will be modifying the tutorial slightly to make this second run-through a little easier. Of course, I'll make a separate news announcement when the Rails 3–compatible tutorial is ready.

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.)
