Great!

And feel free to post any other feedback you may have as you work through the book (hopefully positive, but negative is ok too :-)

Jeff,

That did it. Looks like Mac OS X Leopard ships with Rails 1.2.6. Thanks for the help!

Perhaps you have an older version of Rails? Try this:

rails -v

If it shows something earlier than Rails 2.1, you can install it this way:

sudo gem install rails -v 2.1.1

You can also upgrade to the newly-released 2.2 by just doing sudo gem install rails, but, there are a couple of caveats:

You’ll need to first update your RubyGems to 1.3.1 by doing sudo gem update --system followed by sudo update_rubygems (see http://blog.segment7.net/articles/category/rubygems for more info)
We haven’t had a chance yet to verify that all of the examples in the book still work exactly the same under 2.2, though we’d be surprised if there are any differences.

Let me know if this helps.

Thanks!
Jeff

Hi Cory,

Are you referring to this line?

ruby script/generate scaffold book title:string

This should work fine on Leopard once you’ve generated your Rails app and cd’d into your app’s directory.

Can you reply here with exactly what you’re entering into Terminal?

Thanks!
Jeff

Maybe I’m doing something wrong here, but I tried the Instant Gratification stuff on Mac OS X Leopard (which ships with ruby/rails installed), and the generate failed with the following message:

wrong constant name Title:stringController

Hi Matthew,

Rats! Thanks for pointing that out. Can you add it to the errata page?

And as you go through the book, feel free to let us know if you find the examples helpful (or not), or if there are any concepts you wish we had covered in more detail.

Thanks!

Not sure if this is typo but when I was going through the setup I noticed that on pages 18/19 you reference the path app/views/new.html.erb but for me the path was app/views/books/new.html.erb

Thanks

Hi Jeff,

I didn’t know there was an Errata page – sorry. I like the comparisons to .net development. Pointing out the “Ruby style” is also nice and helps the reader write code that isn’t Ruby with a heavy C# accent.

Hi Andrew,

Thanks for pointing out these issues. Please submit them to the Errata page (http://pragprog.com/titles/cerailn/errata) instead of here, so that can be sure to fix them for the next edition.

If you have any other questions/concerns/comments, this forum is the perfect place, and I’d be interested in your thoughts so far.

Thanks!

Jeff

Page 62

There’s 2 methods nested inside of a method for the C# 2.0 example. Small issue with the LINQ version – if you want to keep the examples functionally equivalent then AddDays(-8) is incorrect.

Editing this post to put all of the chapter 2 issues I found in one post.

The first one is kind of nitpicky, but the wording in the last paragraph of the to_s vs. ToString() section on page 34 implies that the an example of to_s was shown to the reader.

On page 36 the line puts flight.sub(/(w+)\bto/, 'PDX to') doesn’t produce the listed output.

The first line of output is actually the first line of code – flight = "United Airlines, Flight #312, ORD to LAX, 9:45AM to 11:45AM"

There are also some code color issues with the output.

On page 39 there is some markup next to the first line of C# code.

page 52

“A static method called Models() returns a list of available models that can be used.”

Models is a property.

page 53

“In the body of the initializer, we have deﬁned two instance variables, @model and @altitude.”

There are 3 instance variables defined.

Not a huge deal but it’d be nice if the entire command on page 23 had the maroon bold text.

will there be beta versions of this book as with most upcoming titles of “the pragmatic programmer” series?

Thanks for the clarification and prompt response. I’m glad that section was the exception and not the rule. I’m definitely looking forward to publication. It should be a very interesting read.

Thanks for your comment, Lee. You’re right that we didn’t mention LINQ in this particular instance, although we do talk about and have plenty of code samples using LINQ in other parts of the book. I’ll be sure to make a reference to it here before the book is published.

In regards to ASP.NET MVC, we do talk about it and compare/contrast with Rails in the book, although our discussion of it is limited. We’ve been writing this book for about 10 months, and during that time, ASP.NET MVC has been (and still is) in Beta/CTP. We’ve done our best to keep up with its development, but in the end, we chose to focus on comparing Rails to technologies which are already production-quality and are in the hands of the greatest number of .NET devs.

I’m primarily a .Net developer, and this book looks really interesting. But I have to take exception with the following quote in section 6.1 of the chapter: Displaying a Grid of Data in a Table>

“There’s no built-in ActiveRecord-like ORM mapper in .NET, although there are several open-source and commercial packages that are similar in style and function.”

It goes on to say with .Net out of the box you have to use sproc’s or SQL. What about LINQ to SQL? We’re using that extensively on my current project with great success. And all of it’s biggest limitations (like no multi-table inheritence and only working with SQL Server) should be resolved in the forthcoming LINQ to Entities. In fact the entire chapter seems to use an out of date way of connecting controls to databases.

In any event I’m afraid this book will do the .Net community a disservice if it doesn’t at least mention LINQ, if not (ideally) rewrite all examples and comparisons to use LINQ.

Furthermore, I feel there should be a significant part of the book comparing Rails to the forthcoming .Net MVC Framework, which looks very awesome and really exciting. This book could catch a wave of excitement and readership among the .Net community and could really excite developers like myself if it could extensively compare .Net MVC Framework to Rails and then time the books release with the MVC Framework’s release.

But maybe the book is intended for an audience slightly beyond the bleeding (or even cutting if you ask me) edge. Just a thought.
