Repeater with Attachments

[dirschn]

Hi all! Stumbled across this gem (pun intended) a couple weeks ago and am quite impressed with it! I have a question regarding a repeater with an attachment, however. I have a repeater with an image, and was able to access the image tag helper like so:

<% repeater(:name) do |part| %>
  <%= part.content.image_tag(:image_part...) %>

But I'm having trouble doing the same with attachments. I've tried

<% repeater(:name) do |part| %>
  <%= part.content.attachment_url(:attachment_part) %>

and

<% repeater(:name) do |part| %>
  <%= content.attachment_url(:name) %>

And maybe a few more but at this point I don't remember them all.

Curiously, I've noticed that I can download the attachment from the media library and have no problem using the attachment_url helper when it's a single attachment. I've also noticed that the signed_blob_id attribute of the part is populated for the single attachment, but is blank when the attachment is part of a repeater.

I'd be happy to tackle this, but I wanted to double check this wasn't known or intended or anything before I put too much time into it!
