Access attachment url from multiple attachments

We have an article document type where the user can provide a body text and multiple attachments on a Document Attachments field.

Our client wants to support the scenario where there is no body text and a single attachment, so linking to the article opens the attachment immediately.

I am looking at the macro transformations GetFireUrl and GetAttachmentUrl, but they are designed for fields with a single upload file. Is there some macro I can use to access individual items within a multiple attachments field (in this case the first and only attachment where there is only one attachment)?

RE:Access attachment url from multiple attachments

Hello,

If you want to get the first attachment of given document, you can use following macro:

CurrentDocument.Attachments.FirstItem.AttachmentGUID

In case the attachment is an image, you can display it like this:

<img src="~/getattachment/{%CurrentDocument.Attachments.FirstItem.AttachmentGUID%}" />

RE:Access attachment url from multiple attachments

If I put that in the transformation, I get the following in the view:

{%CurrentDocument.Attachments.FirstItem.AttachmentGUID%}

I don't think I understand all the technology here. If you're using the transformation inside a repeater, does CurrentDocument still apply? Also, you're referring to the property "Attachments", but as I suggested, I'm looking at a field that is of type "Document attachments", not the Attachments you add under the Properties tab in the CMS Desk.

What I need exactly is:
- inside the transformation used for a repeater, to access the field of type document attachments, and access the first attachment in the list
- "GetFileUrl" works for a field of type File, but not of type Document Attachments

Hello,

I just want to inform you that from the new hotfix (7.0.10) there is a new property GroupedAttachments where these attachments are listed, so you can use following macro to get their URLs:

{% GetAttachmentUrl(Documents["/home"].GroupedAttachments.test["image.JPG"].AttachmentName, Documents["/home"].NodeAliasPath) %}
