your mainfile (?.rb)

require'rubygems'requireFile.expand_path(File.dirname(__FILE__)) +'/../lib/redismapper'# setupRedisMapper.setup(Redis.new:db=>14)
@r = RedisMapper.db# load your modelsrequire'models'# clean dbRedisMapper.delete_db# insertu = 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)
# readputs"messages (#{Message.count}):"pMessage.all# Message.all(:select => :title) # faster, fetches only the titleputsputs"users (#{User.count}):"pUser.allputsputs"find an user:"pUser.first(:name=>"me")
