Automatically create zip file from some content's file field (Plone 3)

Question

I have a folderish content type as well as a child type inside. The child type has a file field.

Font family (folderish)
 - Font (child)
   - Font file 1 (field)
 - Font (child)
   - Font file 2

I am wondering if I can automatically generate a .zip file which contains all the files of it's children, which I can then link to in the parent's interface.

If so, can you outline the approach? Do I need to use BLOB? I notice there is a product called zipFileTransport, is there a way to add this action to a rule?

Answer 1

I would recommend instead of making a custom content type with a file field, extend the ATFile content type so that you get all the file-like behavior for free. From there you could use collective.zipfiletransport as long as you only allow your file content type within your folder content type.
