create some models

  ## models.rb 

  class Message < RedisMapper

    property :title, :index => true   # enables Message.find

    property :text

    property :user_id                 # connects it to User (atm it doesn't support model's associations via methods but it will be added soon)

  end

  class User < RedisMapper

    property :name, :index => true

  end

your mainfile (?.rb) 

  require 'rubygems'

  require File.expand_path(File.dirname(__FILE__)) + '/../lib/redismapper'

  # setup

  RedisMapper.setup(Redis.new :db => 14)

  @r = RedisMapper.db

  # load your models

  require 'models'

  # clean db

  RedisMapper.delete_db

  # insert

  u = User.create(:name => "makevoid")

  Message.create(:title => "Hello!", :text => "Welcome in the world of redismapper...", :user_id => u.id)

  u = User.create(:name => "me")

  Message.create(:title => "Hello!", :text => "bla bla...", :user_id => u.id)

  Message.create(:title => "Hey", :text => "bla bla..", :user_id => u.id)

  # read

  puts "messages (#{Message.count}):"

  p Message.all

  # Message.all(:select => :title) # faster, fetches only the title

  puts

  puts "users (#{User.count}):"

  p User.all

  puts

  puts "find an user:"

  p User.first(:name => "me")

output:

  messages (3):

  [#, #, #]

  users (2):

  [#, #]

  find an user:

  #
