Javascript error - public_id is undefined about attachinary HOT 4 CLOSED

I wasn't able to reproduce the problem.. The only place where that method is called is within the renderer:
https://github.com/assembler/attachinary/blob/master/lib/assets/javascripts/attachinary.js.coffee#L14

Can you run following code in chrome console and see if there are public_ids?

$('.attachinary-input').eq(0).data('attachinary-bond').files

from attachinary.

When I run that I get:

  TypeError: Cannot read property 'files' of undefined

It didn't find any, probably because I don't see any data attributes on the elements named attachinary-bond -- where is that coming from? I'm assuming this error has something to do with a change in Rails between 3.2 and 4.0.0.beta.

Here's the raw HTML of that file uploader in my form (with api keys removed, etc)...maybe this has to do with the html entity encoding of the JSON?

  <div class="control-group attachinary optional lead_capture_cobrand_logo">
      <label class="attachinary optional control-label" for=
      "lead_capture_cobrand_logo">Cobrand logo</label>

      <div class="controls">
        <input accept="image/png" class="attachinary optional attachinary-input"
        data-attachinary="{&quot;accessible&quot;:true,&quot;accept&quot;:[&quot;png&quot;],&quot;single&quot;:true,&quot;scope&quot;:&quot;cobrand_logo&quot;,&quot;maximum&quot;:1,&quot;singular&quot;:&quot;cobrand_logo&quot;,&quot;plural&quot;:&quot;cobrand_logos&quot;,&quot;files&quot;:[{&quot;file&quot;:{&quot;id&quot;:4,&quot;public_id&quot;:&quot;wdfh9dqqx8nxmqvpsn9z&quot;,&quot;version&quot;:&quot;1362446364&quot;,&quot;format&quot;:&quot;png&quot;,&quot;resource_type&quot;:&quot;image&quot;,&quot;path&quot;:&quot;v1362446364/wdfh9dqqx8nxmqvpsn9z.png&quot;}}]}"

      </div>
    </div>

Using the inspector, when I change data-attachinary to data-attachinary-bond, your debug console test works and my file object is returned, parsed, etc with a good public_id -- question is why is my attribute called data-attachinary when the Javascript is looking for data-attachinary-bond?

Your help is very appreciated. Also I'll be contributing the Rails4 changes back to the Gem once they are tested and ready.

Oh and one other detail -- direct-to-s3 uploading works perfectly and saves to the model, etc. It's just rendering the already-uploaded image in the form that is producing this JS error.

Took a few hours, but I finally figured it out. Appears in Rails4 that as_json returns the "root" by default, which meant each file in the array of files was proceeded by a "file" root instead of just the object itself.

For example, the Javacscript expected the structure to be like this:

  [{id: 1, public_id: "xxxxx" ....} , {id: 2, public_id: "xxxxx" ....}]

In Rails4, it was returning:

  [{"file": {id: 1, public_id: "xxxxx" ....}) , {"file": {id: 2, public_id: "xxxxx" ....}}]

The fix was to pass the option "root: false" in the as_json method in the file mixin. This change will be included in my Rails4 pull request later this week.
