Deploying Rails to Linode

Installing Ruby Enterprise Edition, Apache, MySQL, and Passenger for deploying Rails 3.0 applications.

Get a Linode, and set it up with Ubuntu 10.04 LTS so that you have till April 2013 to get updates. Once the Linode is formatted, boot it and continue on.

Set up an 'A' record in your DNS, pointing to the IP of your Linode. I'm using demo.napcs.com here.

Managing the Flash

HTTP is a stateless protocol. The server, generally speaking, has no idea if request number 243 came from the same user as request number 236. That's beautiful and, at the same time, annoying.

In the context of web applications we frequently want to persist state between requests. That might mean something like a shopping cart that follows a user through the online store, but it can be as simple as a status message.

In modern applications users expect feedback. They click a delete link and they expect to no just see the item disappear, they'll expect a "Item Deleted" message. In Rails we handle these messages using the flash.

Render and Redirect

The normal controller/view flow is to display a view template corresponding to the current controller action, but sometimes we want to change that. We use render in a controller when we want to respond within the current request, and redirect_to when we want to spawn a new request.

Render

The render method is very overloaded in Rails. Most developers encounter it within the view template, using render :partial => 'form' or render @post.comments, but here we'll focus on usage within the controller.
