Hi Niphlod.
Thanks for your answer, I've resolved my first problem, now with
args=row.pdf_path web2py read what there's inside the field. Great.
But I'm still don'tunderstand how I can have an obsolute path.
I've read that host=True can resolve it, but it don't.
In the A helper:
links = [lambda row: A('Catalogue', host=True, _href=URL('default',
'download', args=row.pdf_path))]
Result > http://..../my_application/default/download/http://
www.example.com/mycatalogue.pdf
In the URL helper:
links = [lambda row: A('Catalogue', _href=URL('default', 'download',
host=True, args=row.pdf_path))]
Same result.
Can you help me ?
