[Zope] Method to download a file

[Francois-Regis CHALAOUX]

Hi All,

My problem is to download a file from a FORM. When I click on Submit button I
would like download a file via a dialog "save as". As my following code shows
you, ids input is not used for the moment, later I will construct the filename
to download with this ids. But for the moment I got an error :(.
Is it the right way to do it, what is my error, etc .. I suspect something
with RESPONSE but I can't find something in mailing-list or doc on that stuff.

Help appreciated.

FR.


DownloalForm
============
<FORM ACTION=getPDB METHOD=POST>

  PickleJar.download(RESPONSE)
 
class Trinket:
  def __init__(self,path,type):
    self.path,self.type = path, type
    
  def download(self, RESPONSE):
    RESPONSE['Content-type']=self.type
