It passes the filename (from the record) and the download URL (from the "upload" argument) to the UploadWidget, which automatically adds the link. See here<http://code.google.com/p/web2py/source/browse/gluon/sqlhtml.py#1057>, here <http://code.google.com/p/web2py/source/browse/gluon/sqlhtml.py#1089>, and here<http://code.google.com/p/web2py/source/browse/gluon/sqlhtml.py#556>. I think the record object you pass in must have items for all the fields in the form (i.e., for both tables). > > 2 *or you can create a custom widget for the db field and embed the link > to the file in the widget* > *How to?* > See http://web2py.com/books/default/chapter/29/07#Widgets Anthony --
