Hi everybody I am totally new to rails and I am trying to start a tiny project to get familiar with rails.

hi railers, I have a model/view/controller with many associations (20+). I would like to display the relative associations using AJAX, allowing the user to display the association his/her is interesting at a particular time. Is here any kind ajax tabs helper or some kind of tab widgets that I can easily incorporate into my rails application. regards, leon -------------- next part --------------

Hi, After I''ve saved, I want to display the Description from the Codes table that corresponds with the ID in the Cause table.

That would explain it. The commit messages were quite long (especially the second one) and a commit with a smaller message has shown up. Thanks for letting me know.

"Another Mongrel release?! Is he insane?" Yeah, basically. This is yet another release of Mongrel that adds a bunch of little features people requested and I found were needed. This release is almost entirely targeted at Ruby on Rails folks as the majority of the changes went into the mongrel_rails runner. Get this release from the (correctly linked) site: *
