Well, the attachment retrieval per se is not tied to a web request, but
the AttachmentModule.attachment_data(context) method is specialized for
retrieving attachment data in a form suitable for the actual templates
(attachment.html and macros.html).
So if what you need is the lists of all attachments for a resource,
nothing more, then use Attachment.select(env, parent_realm, parent_id),
which will give you back a list of Attachment instances. It's then up to
you to do the right thing with them.
If you plan to use the list_of_attachments macro from macros.html, then
you can use the AttachmentModule.attachment_data(context) helper method,
in which case the given Context has to contain at least the Resource
corresponding to the parent resource, the PermissionCache object that
will be used to restrict the list of attachment to those which are
actually viewable and a Href that will be used for creating URLs to the
attachments (note that the Request itself is not needed).
