RubyURL.com in a hour...
Ok, I will admit it. I spent much longer than a hour on this. I spent about a hour coding, testing and adding a few CSS tags to the few pages. I spent a few hours trying to figure out why my RewriteRule was not working.
At about 10pm on Sunday evening, I had an idea… hey, I’ll spend the rest of the night on a simple Rails project… and after being sent a link for a tinyurl, I thought, Hey, I’ll just create RubyURL.com. So, I checked godaddy.com, the domain was available and I will now own it until this time next year.
The system thus far comprises of 1 database table, 2 controllers and 1 model that were added to the default rails install. (not including the Rails templates for new.rhtml and show.rhtml).
The random character string function that I used is here: This allos me to create some random alpha-numeric string like ur029class Rubyurl < ActiveRecord::Base def self.gen_random(size=5) chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890" short_url = "" srand size.times do pos = rand(chars.length) short_url += chars[pos..pos] end short_url end endSo, with the standard usage of scaffold I was able to create a random string prior to saving my form:
def create @rubyurl = Rubyurl.new(@params['rubyurl']) @rubyurl['short_url'] = Rubyurl.gen_random(5) if @rubyurl.save flash['notice'] = 'Rubyurl was successfully created.' redirect_to :action => 'show', :id => @rubyurl.id else render_action 'new' end end
The last part in the ruby code was to make it actually redirect to another location:
class GoController < ApplicationController scaffold :rubyurl def go end def index @url = Rubyurl.find_first(["short_url = ?", @params["id"]]) if @url['website_url'] redirect_to @url['website_url'] end end end
... so just over 2 1/2 hours later (mainly due to a problem with the RewriteRule..), I am now happy to announce the alpha release of RubyURL.
I’ll write more about my findings when I wake up.. off to bed.
