#48997: Why isn't the book written using MVC approach. Everything Rails, from tutorials to screencasts use MVC so that readers can see how every piece fits together. I wish I could get my money back. The book is almost useless when all you had is the Models.--Raymond Cudjoe #48997: Why isn't the book written using MVC approach.

#49055: Recipe: 10 - "Connect to Legacy Databases"
Code is in a CDATA section.
When you show how to find and destroy a comment (from the Rails console) the code is in a CDATA section (<![[CDATA ... ]]>), I guess is some kind of "book markup" that should not be seen.
PS: I wrote PDF page 54 because it's on the 54th page of the PDF but I don't know if you want the page number shown in the top-right corner of the page for the erratum.--Aldo Giambelluca #49055: Recipe: 10 - "Connect to Legacy Databases"

#49056: Recipe: 14 - "Create Self-referential Many-to-Many Relationships"
You refer to a Friend model in the phrase "...given the existence of both a Person model and a >>>Friend<<< model." but maybe you meant the Friendship model since there is no Friend model in this recipe.--Aldo Giambelluca #49056: Recipe: 14 - "Create Self-referential Many-to-Many Relationships"

#50378: The example for this recipe doesn't do anything with the registration form once an event is created which is the whole purpose of the recipe.
The reason I'm interested in this recipe is that I have problem I was looking for help with, and I was hoping this example would help me add multiple detail records on a single page (multiple registrations for an event on 1 page). My hope was I could see the routing through web pages by looking at a form that adds multiple registrations on a single page, then use that example to help me figure out the routing and controller structures for my app. Its not so much the form I'm interested in as much as a working example that is similar to my situation so I can glean some clue for how I might solve my problem. I understand if my problem is outside the scope of this example but at the very least it should do something with the registration page. And if this isn't the place for registering example issues then I'm sorry.--scottwood #50378: The example for this recipe doesn't do anything with the registration form once an event is created which is the whole purpose of the recipe.

#49051: Recipe: "Create Your Own Ruby Gem"
After you show the .gemspec file you say "we’ve told RubyGems that our library requires a version of HTTParty in the 1.6 family to be compatible" but in the gemspec file you call s.add_dependency "httparty", "~> 0.6".
Currently HTTParty is at version 0.8.1 so I guess you meant "in the 0.6 family".--Aldo "xoen" Giambelluca #49051: Recipe: "Create Your Own Ruby Gem"
