I am a newbie to programming &lifier ruby (in addition to datamapper &lifier sqlite). I am trying to puzzle out using the 3 but aren't able to find any lessons for novices.

Please tell me of lessons or books.

Thanks.

Both cheatsheet and also the blog publish are a little outdated. I'd suggest searching here:

http://datamapper.org/getting-started

after which feel the official paperwork too:

http://datamapper.org/docs

For those who have any issues you could seek help on #datamapper irc funnel
