Re: Re: [Zope] download a file in a specific folder in the filesystem

2006-08-24 Thread Alan 

Hi! Thanks for your replies.

But for what I want LocalFS or ExtFile sounds too much, specially
because I just need to download. Either, I did not realise yet well
what Richard purposed... However, I tried that:

with a external method
  fname = os.path.join(jobdir,'results.zip')
  file = open(fname,'rb').read()
  return file

but instead of having the file downloaded, it is printed in my
browser, as if it was a ascii file. I guess I need to add a mime type
property here, but I am running out of ideas.

Any commentary would be very welcome.
Cheers,
Alan

If you just want the file to be downloadable from say a web page served by
zope you could make an object on your zope system (say a page template) that
renders a page with a link to the file you wish to make available. The file
would have to accessible to your web server.

Dears,

I would to know how to download a file generated by a program outside zope.
I mean, I would like to download a file via zope webserver and such a
file is located outside the zope space. Since zope treats everything
as a object I have know idea of how importing the link to a file
inside zope space.

I would thank in advance any help.

Cheers,
Alan

Try googling:

response.setheader content-type
response.setheader content-disposition

Exactly.
Something like:
REQUEST.RESPONSE.setHeader('Content-Type', 'application/zip-compressed')
(uhm, not sure of the right spelling)
And return the file object, not its contents. The publisher takes 
care of sending it on chunks if needed.

Thanks a lot guys, it's working fine.

elif (func == 'Download'):
  fname = os.path.join(jobdir,'results.zip')
  file = open(fname,'rb').read()
  self.REQUEST.RESPONSE.setHeader('Content-Type', 'application/zip')
  return file

Cheers,
Alan

Better use 'application/x-zip-compressed' and perhaps:
REQUEST.RESPONSE.setHeader('Content-Disposition', 'attachment; 
filename=suggested-filename.zip')
