jEdit + RubyPlugin is a great, simple Rails development tool, but I was getting annoyed today by the need to open two console windows (one to run Mongrel, another to do rails config or rake work), a Web browser and jEdit, then cd to the depot application folder and manually fire up the Mongrel server every time I wanted to do a little more work on the AWDWR depot tutorial.
I thought about writing up a Windows batch file to start up all this stuff for me, then I realized that I would be cobbling together more or less the environment RadRails provides out of the box.
Since I was well into the depot demo application I wanted to import it to RadRails. A quick Google search let me to Victor Kane's AWebFactory - an amazing resource if you want to use RadRails while following along in AWDWR. Even more so, Victor illuminates many of the darker corners of MVC, OO and Rails that beginners might struggle with. Thanks for taking the time to write this invaluable guide, Victor!
Update (14 May 2007): Aptana has taken over development of Radrails, slowly integrating it into their Eclipse-based Web development IDE. The Aptana team and community are breathing new life into Radrails.
