I've been programming for many years and have just recently got the RoR "itch". I'm thinking about how I could utilize a graphic designer and wondered how best to collaborate with them: 1) Do scaffolding and then show them where to place the graphics in the views (seems ugly) 2) Have them do screens and make them keep a certain dir st...

Is there any way to pick up on this information in my controller and generate JSON responses instead of XHTML? I'm trying to avoid doin...
I'm trying to learn Ruby as well as Ruby on Rails right now. I'm following along with Learning Rails, 1st edition, but I'm having a hard time understanding some of the code.

Some years back I did a bit of Java/Struts development in eclipse, which was nice for its time but my memories of it are not close to what Visual Studio delivers today. Some of the strengths of the MS stack a...

The application has a Message resource and I've defined this custom route to make the URL nicer and more obvious: map.contact '/contact', :controller => 'messages', :action => 'new' How can I keep the URL as /contact when the model fail...
Hey guys, Today, I came a cross a blog post for David Hayden explaining why he thinks ASP.NET MVC developers should learn Ruby on Rails. Some of the reasons David mentioned: ASP.NET MVC was inspired by Rails and in order for me to be a smarter ASP.NET MVC Developer I feel like I need to know Rails. IronRuby is well on its way to...

To make this database easier to work with I have a method set_column_prefix that creates accessors for each column with the prefix removed. ie: # Taken from wiki.ru...

Obviously I can't do the following: Person.Cars.Name(s) ...but does something of that nature exist in ruby (or is there an ActiveRecord helper method) that handles that?...

In my real-world example I'm actually selecting an id from a joined table but it's being typed as a string. I need it to be a ruby integer. ...
I'm running Ruby on Rails on a Solaris 10 server. I just reinstalled Ruby today to get things to work correctly with my MySQL system so I could add a new application I've been working on.
