TG2 downlaoding a file

[adam]

I have my tg2 app and i want a user to be able to download an image.
They click on download, decide where to save the file and then it
downloads. Is there a simple tg2 app for this?

Thanks for any help

ok so i have

@expose(content_type=CUSTOM_CONTENT_TYPE)
def Download(self,file):
username = request.identity['repoze.who.userid']
dir_name = session.get('dir', None)
filename = '/home/rubberduckiee/webapps/editor/Xinha/
plugins/ExtendedFileManager/files'+str(dir_name)+'/'+str(file)

st = os.stat(filename)
size = st[ST_SIZE]

rh = response.headers
rh['Pragma'] = 'public' # for IE
rh['Expires'] = '0'
rh['Cache-control'] = 'must-revalidate, post-check=0, pre-
check=0' #for IE
rh['Cache-control'] = 'max-age=0' #for IE
rh['Content-Type'] = 'image/jpg'
disposition = 'attachment; filename="'+filename+'"'
rh['Content-disposition'] = disposition
rh['Content-Transfer-Encoding'] = 'binary'
rh['Content-Length'] = size


a file downloads but the it fails to open because the file is empty.
What am i missing

Do i need to read the file to an output? if so how?

And you should get rid of the str() - instead, use the encoding your
filesystem uses, and do something like

fname = "/path/%s/%s" % (dir_name.encode("utf-8"), file.encode("utf-8"))
