Ruby On Rails Reference

by Jens-Christian Fischer. Average Reading Time: about a minute.

Tomorrow marks the start of my third Ruby On Rails course. It’s going to be a 3 day course with a (somewhat lengthy) introduction to Ruby (and some of the joys of programming in a very dynamic language) with the rest of the time devoted to Rails. I firmly believe in hands-on training, so the amount of lecturing is minimal. And there are only 5 or 6 participants in the class. They will build an application from scratch – either something from their domain (or if they don’t have any idea) an application that I have thought out.

The course materials consist of the two books “Programming Ruby” and “Agile Web Development with Rails”. In addition, I created a 20+ page summary of the most used Rails commands, functions, classes. It’s based partly on the book and mostly on the source code and it’s documentation. Consider it a giant “cheat sheet” for rails.

I release it under a [Creative Commons][1] license.

There’s the PDF version [rails-reference-1.1.pdf][2] (480 kb) and the [HTML version][5] and you can check out the source code (it’s all written in plain text [Markdown][3]) in the [Subversion repository][4]. The [Changelog][7] will tell you what has changed.

Comments, feedback, corrections are welcome! Oh – and if you like it, feel free to [Digg it][6]

    That’s a very nice move – to publish your ROR course for free. Next week I will start my first Rails project, and I am pleased at your tips.

  33. Andy says:

    great reference. handy to have a pdf to search locally too!
    thanks

  34. RailsNuby says:

    @71 – This really is a great reference. Is a 1.2 version still in the works? If so, do you have a timeline? If not, will you re-release the source so that others can update it? (I couldn’t access the subversion version via the published link – http://invisible.ch/projects/browser/rails-seminar/doc ).

  35. Administrator says:

    Yes it still is in the works and will hopefully surface RSN…

    I’ll look into the SVN problem…

  36. Nic says:

    Thanks a bunch for the PDF as im learning Ruby at the moment it has proven very useful.

  37. WIllem de Ru says:

    Thanks, this is an excellent help! And I am also looking forward to the 1.2 version. Thanks!
