[Rails] Re: Getting started with ROR when you come from the desktop world with no experience in developing web application

2008-11-03 Thread Chris Haupt

If you are more of a "watching/listening" follow-along learner than a
"reading" oriented one, there are some extremely useful screencast/
podcast resources that you may want to plug in to (some free, some for
a modest cost):

http://peepcode.com/ has a selection of screencasts and PDFs over an
ever-increasing set of topics ($9/each)

Ryan Bates' Railscasts (http://railscasts.com/ and iTunes, free) are
an excellent source of free, very focused screencasts on one technical
topic per episode

Our own LearningRails.com course (free, iTunes and http://LearningRails.com/),
is a gentle, step by step "class" where we build a _very_ simple CMS-
like app, showing all the behind the scenes nitty-gritty. We provide
linked show notes and articles from BuildingWebApps.com that go from
tool installation, Rails programming, testing, and deployment. Some of
the older episodes need a Rails 2.1+ tune-up, but the comments contain
the important pointers.

The Pragmatic Programmer's new screencast series (http://
pragprog.com/, small fee), has several Rails and Ruby oriented
products.

The RailsEnvy screencasts (as well as Gregg and Jason's news oriented
podcast, http://railsenvy.com, small fee on screencasts), are an
entertaining resource that discusses the latest and greatest in RoR.

Basically, there is a wealth of non-book resources, so worth at least
book-marking as you learn.

Good luck,
-Christopher

Sometimes exception handling code can eat useful error messages,
especially if you don't capture and display the exception object, you
may miss useful info. When diagnosing things, I occasionally find it
is useful to comment out the rescue clause and let the error bubble to
the surface. Alternatively, capture it (e.g. rescue Exception => e)
and display in your rescue clause with a logger or similar output.
