CouchDB map that provides doc id and attachment names for easy URL conversion

couchdb_view_attachment_names

// view map for generating URLs to stubbed attachments
function(doc) {
  if (doc._attachments) {
    for (var i in doc._attachments) {
        emit(doc._id, doc._id + "/" + i);
    }
  }
}

// example document

{
   "_id": "de14d389737bb89780aa32e1cd001864",
   "_rev": "5-9ec2472a23b1267822ccfa6df3df2bcd",
   "notes": "some notes",
   "_attachments": {
       "blah.txt": {
           "content_type": "text/plain",
           "revpos": 4,
           "length": 28,
           "stub": true
       },
       "foo.txt": {
           "content_type": "text/plain",
           "revpos": 2,
           "length": 18,
           "stub": true
       }
   }
}

This will return a k/v like this:
