[Zope] Re: [Projet-zf] Download a file from a form

[FR Chalaoux]

Hi,

I fixed the problem :

getPDB method
=============
<dtml-var "getfiles(REQUEST, REPONSE)">

getfiles.py Extension file
===========================
def getfiles(self, REQUEST['ids'], RESPONSE):
  PickleJar = Trinket('/me/foo-ids.gz','x/gzip')
  PickleJar.download(RESPONSE)
  blah, blah ...

But now , when I save the file the filename is getPDB (getPDB method is took in
fact), not the name of my downloaded file.

Any solution ?
