this get method seems to be working but there are errors in the console

I have the script below:

disallow_part = {
  disallow_part: '#disallow-part'

  init: ->
    @setListeners()

  setListeners: ->
    $(@disallow_part).live 'click', ->
      partId = $(this).data("part-id")
      augmentId = $(this).data("augment-id")
      $.get("/parts/#{partId}/disallow_part_for_augment/#{augmentId}", null, 'script')
}

It seems to be hitting that route because records are being added to the db but in the console I get this error.

GET http:***/parts 404 (Not Found)

Any idea what's going on?
