Hi, I am thinking about how to best design a quiz site in RoR. I think it should be fairly easy, but have run into a wall. In the simplest form, the view would grab all of the questions for a particular quiz and display them (e.g. multiple choice, so 4 option buttons per question).

...html and noticed that the the link to the Dilbert site on http://www.unitedmedia.com/comics/dilbert/ isn't working. I'm a Dilbert fan myself :) so I thought I'd mention a page I have bookmarked: http://www.answerconnect.com/articles/dilbert-fans It has a bunch of neat fan sites and quizzes and whatnot. I figured it might be a good addition to your page, if you were going to replace that dead link. Hope I could be of some help. Have a good day! -Angelica

I have a magical proposal for the anti-magic web framework. Controller methods do not use arguments and yet expect arguments. This is handled through this params hash because we don''t know in advance what parameters a client could pass to Merb. But in almost every instance, it is too much to know all the query parameters - one doesn''t care if the user threw in an extraneous
