Why RoR is Awesome (part 1 of many)

I finally took the plunge. I’m learning Rails. And holy shit.

RoR has a philosophy of being RESTful, which means using what’s already built (HTTP) rather than reinventing the wheel.

I launched a “users” app using just these three commands taken from the tutorial I’m following:

rails generate scaffold User name:string email:string
rake db:migrate
rails server

With no further modifications, check this out (truncated for brevity):

> telnet localhost 3000

> POST /users HTTP/1.0
> Content-Length: 57
> 
> user[name]=Dustin&user[email][email protected]
<html><body>You are being <a href="http://localhost:3000/users/1">redirected</a>.</body></html>

> GET /users.json
[{"id":1,"name":"Dustin","email":"[email protected]"}]

> GET /users/1.json
{"id":1,"name":"Dustin","email":"[email protected]"}

> DELETE /users/1
<html><body>You are being <a href="http://localhost:3000/users">redirected</a>.</body></html>

> GET /users.json

This is exciting stuff I tell you. And I’m only on chapter 2!
