Part 2 of Ruby on Rails Tutorial Online

Posted by Zonk on from the productive-coding dept.

An anonymous reader writes "Curt Hibbs has released Part 2 of his tutorial Rolling with Ruby on Rails to the O'Reilly ONLamp site. The first part was published in January. Topics covered are database transactions, callbacks, unit testing and caching." From the article: "In Rolling with Ruby on Rails, I barely scratched the surface of what you can do with Ruby on Rails. I didn't talk about data validation or database transactions, and I did not mention callbacks, unit testing, or caching. There was hardly a mention of the many helpers that Rails includes to make your life easier. I can't really do justice to all of these topics in the space of this article, but I will go into details on some of them and present a brief overview of the rest, with links to more detailed information."

    It's rough, but it's coming along.

    Has anyone actually done some interesting stuff that now works in a productive environment?

    "A Rails web application can run under virtually any web server"
    Now that really made me curious. Is that really true, tried, and tested? If so, we need another bunch of tutorials about how to use Rails under Tomcat, Apache, etc. There is no way this framework will replace existing Java frameworks, but using it for prototyping is promising.

  4. ROR rocks! by Pfhreakaz0id · · Score: 5, Interesting

    As a guy who has written db-driven web apps in ASP, asp.net ( alittle), perl CGI, plain JSP/Servlet and j2ee app server with EJB's (both with and without a persistence framerwork/Object-relational bridge), I can tell you ROR is my favorite. I've only been using it for two weeks on a part-time project. It's ... beautiful. I can't think of any way to describe it. It. Just. Works.

    And ruby is a really nice scripting language. You should check it out.

  5. Comparing RoR with Java solutions by MarkWatson · · Score: 4, Interesting

    I have worked through the RoR tutorial and re-implemented a simple admin web app that I originally wrote for a customer using JSPs and Tomcat. I must say that what took me 4 hours to write using JSPs and JDBC took about 30 minutes using RoR.

    A big advantage that Ruby and Python have over Java is that they are dynamic languages that makes it not too difficult to write a database wrapper class that dynamically looks at database/tables meta data and generates access methods on the fly. Java Tails (using XDoclet market tags) can't really compete.

    I really love the full J2EE stack for developing large scalable web applications but I am now looking at alternatives for creating smaller systems much more quickly.

    BTW, I really like RoR's templating scheme: much like JSPs in syntax (JSP non-XML syntax, that is) but do to Ruby's much terser notation for enumerating collections, the the templates tend to look a little cleaner.

    For Python, I really like the light weight CherryPy web application framework. I plan on checking out Python Subway also when I have some time.
