Using RubyAmf for creating a CRUD application in Rails

CRUD applications can be easily created using Ruby on Rails as the backend and Flex as the frontend app using the XML format as demonstrated here.

Another way to create such applications is using the AMF protocol which is optimized for network communications and stores objects in binary format so consumes less bandwidth. Another compelling reason for using this library is that it doesn’t feel like a hack as it integrates very nicely with Rails :)

The Ruby port of this protocol known as RubyAmf can be downloaded from from here. More information about this protocol can be found here.

Lets start making the application.

Create a Rails Application:

   1: > rails amf_demo

This will create a rails application. Please note that I am using Rails 2.1.2 for this example and it is not tested on any other Rails version.

Generate a scaffold:

   1: > ruby script/generate scaffold blog_post title:string body:text

Create Tables and run Migrations:

   1: > rake db:migrate

   1: > rake db:create

Using Silverlight with Ruby on Rails

In this post I will be showing a really simple example of creating a Silverlight frontend for a Rails backend. This is what I think will be a three part series comparing Silverlight with Flex.

The steps will be:

1. Creating a Rails application.
2. Creating a frontend for it in silverlight.
3. Creating a frontend for it in Flex.
4. Comparing the approaches taken in both the frontends.

I will try to keep changes in the backend Rails application to a minimum.
