12-Mar: RailTrackr article has been published on DevX

DevX.com has published my latest article, an introduction to Ruby on Rails 2.0 that uses RailTrackr as a sample application to describe the topic. See my full list of articles for other topics.

I enjoyed reading through the article and watching the screencast. Nice work. Thank you.

Couple of minor observations:

(1) The "flickr_helper.rb" file, as described on page 2 is located in the /lib folder, not in the /config directory (which is where I went looking for it, or in the source code root (which is where the article text kind of led you to believe it might be)

(2) Nothing worked until a database stub was setup and migrated; a point not addressed in the setup steps.

(3) The initial page load at localhost:3000 took quite awhile while (I assume) the connection and files from Flickr were being setup. You might make a mention of this in the article.

(4) The "Pastie" link is down.

Hi Robert, thanks for your tips. I'll forward them to DevX.com to have the article updated.

Point 2) is a bit strange, since when developing the sample I've never touched nor configured the database and everything worked ... can you send to my mail address the steps you followed and the error message that Rails printed out? I'll investigate on that.

Unfortunately the Pastie link was working the night before publishing the article. That resource is currently out of my control, but I hope it will recover soon. "Pastie" is just a sort of public clipboard when lots of people dump there their scripts. This particular one just scans the ruby files of your rails application applying regexps to find out potentially troublesome function calls (such as deprecated or obsolete ones).
