Offers nothing 24 mars 2007
Par Hans C Masing - Publié sur
Format: Broché
While I really hate to slam down the authors of the book, this text really offers nothing to readers that isn't in better form elsewhere. The text is ridden with buggy code, incomplete explanations, and the style of coding leaves much to be desired. The "Agile Web Development with Rails" text (also available on [...]) builds nearly the same application (an eCommerce site), but does so while explaining the rails framework as well as offering up a solid reference textbook style for later use.

I teach graduate level computer science, and switched my curriculum to Ruby on Rails this term for my "Complex Websites" course. I reviewed many books, and this one ended up at the bottom of the pile. Sorry.

Good book ruined by sloppily coded examples 8 février 2007
Par Ronald H. Bingham - Publié sur
Format: Broché
It's too bad this wonderfully written book is so full of errors. Did the authors run out of time to check the sample code? I spent days and days trying to get the sample code given in the book to work. The book version of the code didn't match the downloaded version and both were loaded with errors. After chapter four I gave it up as a lost cause. My list of errata was so extensive that I didn't bother to send it to the publisher because I had invested far too much time in the book already. I'm guessing the rave revues this book received were from readers that simply read the book and didn't try the sample application code.

Full of errors and instructions are missing... 11 décembre 2006
Par uml_zepho_com - Publié sur
Format: Broché
Beginners must stay away from this book. It does not mention anywhere that you must install RedCloth to get the textilize method working. There are too many errors in the book to mention them all here. The code given in the book fails to run due to a bug in the Rails code, one of the problem is due to the assert_tag bug in Rails. The fix shown on the reviewer's website does not solve all the problems. Again the book does not even mention about the workaround. After many hours of frustration you have to find out from other developers on the Rails mailing list.

For a beginner, it is very frustrating when the book fails to mention when the fixtures need to be updated to make the code work. Even after copying all the code for the corresponding chapters from the downloaded source, it still gives errors.

Buyers be careful about the other reviews giving 5 stars for this book. For an objective view and to see the problems with this book, search the Ruby on Rails mailing list on the title of this book. You will see how many developers are having the same problem.

You can buy this book only after the publisher fixes all the errors. Otherwise you will end up with lot frustration and wasted time and energy.
Unfocused and useless --- don't bother 9 avril 2009
Par Richard C. Yeh - Publié sur
Format: Broché
This is one of the worst Ruby on Rails books I have ever checked out of the New York Public Library. While most RoR tutorials have the reader build a blog, E-Commerce's main example is "Emporium", an online bookstore. I can only guess that the authors failed to define their audience, and the result is a book that tries to include too much:

Getting requirements from the customer;
Installing RoR on Windows or OS X;
Scrum (sprint development process);
Test-Driven Development;
Security (merely 30 pages);
Checkout and Order Processing (50 pages);
Performance Optimization (20 pages);

In every chapter, the authors begin by presenting the requirements that you are to solve. That structure may be a nice concept, but the execution is bad. Little snippets of information are included here and there. The examples presented at the beginning of the test-driven development section have little or nothing to do with the tests in the rest of the chapter. After the requirements for every chapter, the reader is supposed to follow the instructions, and that's it.

Hardly a page goes by without the authors mentioning some tip or note that tells you to go to Wikipedia for more information, or to look in the README file that accompanies the software. While the educational intention is good, this shows a basic lack of editorial discretion, even for a book published in 2006.

The Security chapter's requirements consist of a login process with a rejection screen and the ability to reset passwords. I find it laughable that that's all one needs to care about security.

The Checkout chapter mentions several [ruby]gems to install that will take care of payment processing.

The book is totally unfocused: if the reader is at the stage where s/he hasn't installed Ruby, then the presentation is too telegraphic, and I'd recommend Eldon Alameda's Foundation Rails 2. If the reader is a requirements-getting developer, then the level of the presentation is too low, and s/he should look to Mike Clark's Advanced Rails Recipes, which also contains payment processing gems.

A fantastic book 11 décembre 2006
Par Johannes de Jong - Publié sur
Format: Broché
Once in a while a book gets written that makes your life as a programmer easier; this book is one of them.

Why you might ask? Well to start off with I can use +/- 60% of their demo application, emporium, as a basis for a application I've started writing; and my application has absolutely nothing to do with a book store. Their application addresses common tasks i.e. standard CRUD, security, multiple language support etc. things you will encounter in any web-based application. They show you how to solve them the Rails way.

I've never fully understood the fuzz about the Test Driven Design and I thought that writing test code before writing the actual code meant you were bananas. I know better know. If you follow their advice and example, boy do they write a lot of test code in their application, releasing your code to production won't be the dreaded "gone is my weekend" event it used to be. Thank you for showing the way guys.

I also like their writing style, it is as if you are part of the discussions with the user, George, as the application evolves from an idea till a pretty sophisticated amazon type clone. Everything is done using extensive user stories and you fully understand their reasons for their solution to the problems.

Even though this book is not a reference book I'm quite sure I will return to it often when writing my own application(s) to see how the authors did something. As such I have one small gripe I wish the formatting made it easier to find things.

This book has everything you need to take your level of understanding / knowledge of Rails to higher level and as a bonus it will also make you a better programmer general; I highly recommend this book.
