I have this in my view:

<a href={{URL(r=request,f='csv',vars=dict(query=query))}}>
   Download as csv-file </a>

And this controller:


def csv():
   import cStringIO
   s=cStringIO.StringIO()
   response.headers['Content-Type']='application/vnd.ms-excel'
   
db(request.vars.query).select(db.sarua.All,limitby(1,250)).export_to_csv_file(s)
   return s.getvalue()


When I click on the link, it seems the browser shows some sort
activity but there is no download taking place. What am I doing wrong?

I will be so glad if I can get this working.  I have spent many hours
in trying to get it to work.

Regards
Johann
