I am attempting Bruno's above code to display the saved PDF, i have created
a link in my index page that takes me to the viewer page but when i click
it i get an error message below:
<type 'exceptions.AttributeError'> 'NoneType' object has no attribute
'fileS'
* MODEL CODE:*
db.define_table('pdfs',
Field('fileS','upload',uploadfolder=request.folder+'static/pdfs'))
*CONTROLLER CODE*
def viewer():
row =
db(db.pdfDocs.id==request.args(0)).select(db.pdfDocs.fileS).first()
redirect(URL('static','pdfs',args=row.fileS))
*VIEW CODE (index)*
*{{extend 'layout.html'}}{{=A('Click to view', _href=URL('default',
'viewer'))}}*I changed the 'file' variable because it said its an "ALL"
reserved SQL/NOSQL keyword
What can i do to make this link redirect me without an error i'm getting??
Regards;
