example app not working with 0.4.1 gem

I had this same issue. The gem now expects that the json returned is in an array of files. Old code:
format.json { render json: results.to_json }
New code that works:
format.json { render json: { files: results}.to_json }

Indeed, my index.js.jbuilder looks like:

json.files @photos do |photo| <----- this line is json.array!(@photos) do |json, photo| in the example
json.name photo.image_file_name
json.size photo.image_file_size
json.url photo.image_url
json.thumbnail_url photo.image_url
json.thumbnail_url photo.image_url(:thumbnail)
json.delete_url album_photo_url(@Album, photo)
json.delete_type "DELETE"
end

took a whole freaking day to figure out :/

@raydog153 I dont get it. Where I will put format.json { render json: { files: results}.to_json }. I know it was supposed to be in the controller, but doesnt the gem call the create action once for each photo? And even worst in my case I'm trying to load the results on the products form so that I can associate the photos w/ the product I'm creating. This way I can't use index like @quazimodo have done since it would bring all of them to my form, or not?

Is this issue anyhow related w/ this one tors/jquery-fileupload-rails-paperclip-example#13 ?

UPDATED: I don't think so. Since in the sample I changed the line

{ render json: {files: @Upload}.to_json, status: :created, location: @Upload }
And its still rising

Uncaught TypeError: Cannot call method '_adjustMaxNumberOfFiles' of undefined

Thanks

So I was commenting to adejoux that after I upgraded to 0.4.1 my code was not working, and the fix was to change my json response as I stated above. Your json response looks correct, after I did that everything worked. I did not change the gem in anyway, I had to change MY code. As for the calling, I think it depends on your settings, as I have singleFileUploads and sequentialUploads both set to false. I can upload multiple images and my controller code only gets called once and I send the result of all the files back in one json response. Is this clearer?

@raydog153 Hello! Thanks for your answer. I'm finding this jquery plugin really challenging but you're right the gem is perfect. It turned out that all I had to do to get the paperclip example working and get rid of that error was changing this line

format.json { render json: [@upload.to_jq_upload].to_json, status: :created, location: @Upload }

to:

format.json { render json: {files: [@upload.to_jq_upload]}, status: :created, location: @Upload }

And I made the same thing on my app.

Things are getting clearer but in a very painful way, but my fault, I'm new with js and jquery.

Hi, same problem for me :(
0.4.0 can work , and 0.4.1 or master can not work, I think you made some errors with jquery-file-upload version.

[sharp]

I think need to change
var fu = $('#fileupload').data('fileupload')
to
var fu = $('#fileupload').data('blueimpFileupload')

[sarink]

Just to be clear, here are the changes which made 0.4.1 work for me..

In uploads_controller create action:
format.json { render json: {files: [@upload.to_jq_upload]}, status: :created, location: @upload }

In your js:
var fu = $('#fileupload').data('blueimpFileupload');

[klausistblau]

Works also with current example code (http://blueimp.github.com/jQuery-File-Upload/):

      $('#fileupload').addClass('fileupload-processing');
        $.ajax({
                url: $('#fileupload').attr('action'),
                dataType: 'json',
                context: $('#fileupload')[0]
            }).done(function (result) {
                    $(this)
                    .removeClass('fileupload-processing')
                    .fileupload('option', 'done')
                    .call(this, null, {result: result});
                });

But I also had to update the index action:

format.json { render :json => { :files => @videos.map{|upload| upload.to_jq_upload }} }

EDIT: and the post action :)

format.json { render json: { :files => [@video.to_jq_upload]}, status: :created, location: @video }

Using:
rails 3.2.13
jquery-fileupload--rails 0.4.0 and 0.4.1

I can confirm that changing:

 var fu = $(control_id).data('fileupload'),

to:
```javascript
var fu = $(control_id).data('blueimpFileupload'),

Fixes empty file list...for me anyway.  I changed nothing else just that one line of javascript.

@tors This ticket can be closed

[amitpatelx]

I am facing this issue.

I cloned @digitalfrost 's PR and upgraded to rails 4.2.4 and jquery-fileupload-rails 0.4.5.

[Praveen-Invoscape]

I am also facing that same issue anyone give some ideas to solve that

[sarink]

Guys, check the dates. This issue was opened and answered in 2013, Rails 4 didn't even exist then! I think you're on your own...
