customers.unpaid
  # => <#Customers [{:paid=>false, :credit=>2000}, {:paid=>false, :credit=>0}]]>
  
customers.scope { select { |y| y > 1000 } }
  #=> <#Customers [{paid: true, credit: 1000}, {paid: false, credit: 2000}]>
  
customers.sum(:credit)
  #=> 3000
  
customers.create({paid: true, credit: 1500}) # defaults to Hash creations
