  parse: (response) ->
    response.floors

  alreadyExist: ->
    @.filter( (floor) ->
      return floor.get('number') == @.attrs.get('number')
    )

add_floor: (e) ->
  console.log ' Saving Floor '
  e.preventDefault()
  floorNumber =  $('input[name=floorNumber]').val()
  floorDescription = $('input[name=floorDescription]').val()
  return new NoticeView({ message: "Please enter a Floor Number.", displayLength: 10000 }) unless …
