Using jquery fileupload with coffeescript - resizing an image using add callback

Question

solvable Turns out js loading order in application.js is wrong:

original:
//= require jquery-fileupload/jquery.fileupload-process
//= require jquery-fileupload/jquery.fileupload-image
//= require jquery-fileupload/jquery.fileupload-validate

correct version:
//= require jquery-fileupload/jquery.fileupload-process
//= require jquery-fileupload/jquery.fileupload-validate
//= require jquery-fileupload/jquery.fileupload-image

I am trying to use the jQuery BlueImp file loader, and I managed to get everything except resizing.

I am trying to resize images in the add callback and then send to avoid server side processing.

I know that using the add callback causes the process function to be skipped, but I manually called it in the add callback itself, and it should work, but it doesn’t.

here is my code:

$('.jquery-fileupload').fileupload
  dataType: "script"
  imageMaxWidth: 480
  imageMaxHeight: 360
  disableImageResize: false
  autoUpload: false
  process:[
    {
      action: 'load',
      fileTypes: /^image\/(gif|jpeg|png)$/,
      maxFileSize: 20000000
    },
    {
      action: 'resize',
      maxWidth: 480, // the images are to be loaded into a pdf later so they have to be skept small
      maxHeight: 360,
      minWidth: 480,
      minHeight: 360
    },
    {
      action: 'save'
    }
  ]
  progress: (e, data) ->
    progress = parseInt(data.loaded / data.total * 100, 10);
    $('#progress_'+data.formData.token+' .bar').css('width', progress+'%')

  add: (e, data) ->
    unique_token = token();
    if (data.files && data.files[0])
      if(data.files[0].size < 200000000)
        if(data.files[0].type.substr(0, data.files[0].type.indexOf('/')) != 'image')
          alert("Please upload a file with the correct format")
        else
          current_data = $(this)
          data.process(->
            return current_data.fileupload('process', data); //call the process function
          ).done(->
            data.formData = {token: unique_token};
            data.context = $('.preview:last');
            data.context.find('.abort').click(abortUpload);
            xhr = data.submit();
            data.context.data('data',{jqXHR: xhr});
          )
      else
        alert("one of your files is over 200MB")
  done: (e, data) ->
    console.log(data);

any help on this subject would be greatly appreciated since I hit my head on the table for 2 days right above it!
