I like how interpreted languages provide this interpreter for you to try out stuff. As I am learning ruby on rails I frequently need to try out ActiveRecord's dark ways of doing things and I would like to be able to try it out in irb so here is what I do
Launch irb
irb --simple-prompt
and then execute the following code assuming you are in the rails app directory
require 'rubygems'
require 'active_record'
require 'yaml'
Dir.glob(File.join(File.dirname(__FILE__), './app/models/*.rb')).each {|f| require f }
dbconfig = YAML::load(File.open('./config/database.yml'))
currenv = ENV["RAILS_ENV"]
if not currenv
currenv = "development"
end
currdbconfig = dbconfig[currenv]
currdbconfig["database"] = currdbconfig["database"]
#p currdbconfig
ActiveRecord::Base.establish_connection(currdbconfig)
After thins you can try out your model methods in the prompt.
This works with MySQL and should work with sqllite3 without any problems

Excellent! just what I needed.
Or you could change to your rails app folder and run rails console. No need to load config files, etc. manually.
