Our next book is "Crafting Rails 4 Applications" (http://pragprog.com/book/jvrails2/crafting-rails-4-applications) - make sure you get the Rails 4 version, not the original which was written for Rails 3. For next week we will be reading the second chapter: Building Models with Active Model. Please read the book and try out the code at home. Then come to group to discuss what you did and did not like about the implementation. What worked, what didn't.
