Paul Sturgess posted a nice little tip on how to How to use Capistrano 1.x to deploy Ruby on Rails apps when you have Cap 2.x. Basically, the following syntax will allow you to choose which version of a gem to run:
cap _1.4.1_ deploy
Or say you want to generate a 1.2.3 rails app:
rails _1.2.3_ […]
The fellows over at Err have finally seen the light of jQuery. My first thought is welcome to the party, we’ve been wondering when you’d get here. From my first days with rails, I’ve been using jQuery over Prototype. Why? Well, a lot of reasons, but the biggest one is because […]
Taking Merb to Production
A good up and running with Merb tutorial.
has_many :through: Finding unassociated objects

I ended with a summarizing rule that says when you end an action with render, you generally want to use flash.now[:notice], and when you end an action with redirect, you want to use flash[:notice]. While simple, I hate remembering that rule, and what really complicates things […]
You’re just starting on rails and you’re very excited about the ease of flash[:notice]. But every now and then, you set a flash notice and it seems to follow your clicks to the next action when it shouldn’t. Why? I’ll tell you.
Intro to flash[:notice]
flash[:notice] belongs to FlashHash.The basic use of the flash hash […]

@project = Project.find(params[:project])
if @project
@project_product = @project.project_products.create(params[:project_product])
if @project_product.valid?
# Do something with success
