# uber-hacky dynamic collection names for MongoID models:
# 
# class MyModel
#  include Mongoid::PrefixableDocument # ...instead of Mongoid::Document
#  include Mongoid::Timestamps
#
#  field :foobar, :type => Integer
#
#  def my_method; 123; end

If you want to use multiple dbs at once there are several different ways... 

1) If you want to do this on a per-model level, use .store_in (This is for all threads):

class Band
  include Mongoid::Document
  store_in database: "secondary" # This can be any name you want, no need to put it in the mongoid.yml.
end

class Artist

  puts header[0].split('_').last + ': ' + header[1]
end

class Array
  def each_valid
    self.each do |val|
      valid = yield val
      puts val if valid
    end
  end

  def map
    internal_array = []
