Hi, I''m looking for a way to extend one of my models to allow some level of abstraction between what goes into it and how it is stored. For example, say I have a Product and I want to set it''s price. A person using the website will type the price in euros. Internally, I''d like to store the price as an integer value of cents.

Hi all, I would like to start a thread on RoR related issues on the new Intel version of Mac OS X. I have been using Apple''s new iMac Core Duo (which comes with Intel version of Mac OS X) for about a week now. Here''s my experience: Ruby 1.8.4: It compiles albeit with many warnings.

Hey all, I''ve been battling with ruby configurations for days now...trying to get either SCGI or FCGI to work on my Apache 1.3/Linux Red Hat 3 server. I''ve pretty much gave up that battle since either of them will work with me after trying dozens of configurations, but now even when I try to run apps with dispatch.cgi I get this error in my log: "Premature end of

i guess its better form to keep form tags outside of table tags anyways, but it took a lot of trial and error to figure out thats why @params were no longer showing up after switching form_tag to form_remote_tag. not sure if this is a prototype ''bug'' or ''feature'' or what. but my next step was to switch to a seperate form tag for each row to reduce needless

Hi everyone, Newbie here. I''m trying to get a textual form element to submit in the context of a form_remote_tag block and having little success. Oddly (or perhaps not), using regular old form_tag in its place does cause the elements to be submitted.
