I used the one-click installer to install 1.86 a while back. I wanted to upgrade to 1.9 but since there's no one-click installer for 1.9 I just downloaded the 1.91 binary and overwrote my 1.86 install. Didn't work so well. I got errors all over the place afterwards. What's the proper way to upgrade (for a dummy, i.e. me)? The downloa...

I want to be able to validate a date in my model in ruby on rails. However, the day, month and year values are already converted into an incorrect date by the time they reach my model. For example, if I enter February 31st 2009 in my view, when I do Model.new(params[:model]) in my controller, it converts it to March 3rd 2009. Which my m...

I'm really new to Ruby. And by new - less than 16 hours, but my boss gave me some Ruby code to add to. However, I found it was one giant file and not modular at all, so I decided to clean it up. Now that I've broken it up into several files/classes (generally speaking, 1 class per file,) I'm having problems piecing it together for it to ...

I have just bought a MacBook for some ruby development and like the look of Aptana Studio as a really nice IDE. The question I have, however, is that I want to know (before getting too deep into it, and potentially wasting time) is can I create plain old .rb files without the rails framework attached? Also, can I execute the ruby file ...
I'm using Ubuntu 8.10 and I installed Ruby and Ruby on Rails following the directions on this site. The exact directions I followed are no longer there as it appears the rubyonrails.org wiki has changed recently. But I installed it the long way. Installed Ruby, then Gems, then installed Rails using "gem install rails". I haven't really m...

I have recently been building very small and simple apps using Locomotive 2.0.8. Until now it has been the ideal solution, but recently the application has slowed to absolute crawl. It takes literally 10 minutes to boot up, 5 minutes to add an existing or new project - and often these creations don't even work correctly. I can't imagine ...
Hi all, Since the beginning, Rails has had issues with namespaced models. As time went on, pretty much everybody gave up on using it. Myself included. With Rails 2.3 out, I'd like an update on the situation. Specifics questions I have in mind are: first off, is it good to go? table naming, what rule to follow? associations, how to d...

Requirements: When user clicks on image, it should be immediately known to a controller in an Ajax way. Some strings should be passed to a controller when user clicks on image. Controller does its...
