Does anyone have a good resource for MongoMapper documentation? I've been reading through the mongoDB docs, but a 开发者_Python百科lot of it doesn't convert across to ruby/mm. I've been trying to figure out how to do a SELECT FROM WHERE EXISTS with little success.

db.things.find( { a : { $exists : true } } ); // return object if a is present

The only docs I've found so far these which have helped a little.

Thanks.
