Question

I have this line:

@users = database['users'].find(:all).limit(10)

it returns this object:

<Mongo::Cursor:0x8759a858 namespace='app-development.users' @selector=:all @cursor_id=>

and what I thought was that it has a collection of the 10 users it got from the database. Is that correct? I tried iterating through it like this:

   @users.each {
        |info|
      logger.debug ".....................single user: " + info.inspect
    }

but I got this error:

BSON::InvalidDocument (BSON.serialize takes a Hash but got a Symbol):

Help much appreciarted!

I’m not framiliar with mongo but try this:

@users.each do |info|
   logger.debug ".....................single user: #{info.inspect}"
end

The #{} allows you to evaluate ruby code within a double quoted string.
