Sorry, I should have also provided the "subscribers.index_content"
function so you could see its argument list:
def index_content(obj, event):
""" Index content (an IObjectAddedEvent subscriber) """
catalog = find_catalog(obj)
if catalog is not None:
for node in postorder(obj):
if is_content(obj):
path = model_path(node)
docid = getattr(node, 'docid', None)
if docid is None:
docid = node.docid = catalog.document_map.add(path)
else:
catalog.document_map.add(path, docid)
catalog.index_doc(docid, node)
