# but how do use this named_scope in a wrapper method so that i only get the first object back?
# i tried it like this:

  def current_selection
    scope = self.scoped :conditions => ['ipayment_confirmed = ? and confirmed = ?', false, false]
    scope.first
  end

# but this doesnt work:

>> User.first.checkouts.current_selection
NoMethodError: undefined method `current_selection' for #<Class:0xb6a85bf4>
