Ruby and Mongo - how to query for a collection

I have a database connection that I got like this:

db = Mongo::Connection.new.db("app-development")

but when I tried querying for a collection like this:

@users = User.all.limit(50)

I got this error:

NoMethodError (undefined method `users' for #<Mongo::DB:0x10ed5f3b8>):

My collection is called users. What was the right way to get that data?

Thanks!

Solution is this:

db = Mongo::Connection.new.db("app-development")

becomes

db = Mongo::Connection.new.db("app-development").collection("your_collection")

Then you will be acting on the database in the way you are imagining.

Are you sure that you've got the right case on users? is it 'Users' or 'users'?

you could try: 

@users = users.find("").limit(1);

This is the resource I used to learn... http://api.mongodb.org/ruby/current/file.TUTORIAL.html
