This MUST be something I'm doing wrong. I have used this very code -- even
this method -- countless times but now it fails to stream the file. The
object being streamed is a StringIO buffer of some file that I create on
the fly. I'm trying to download it with a provided file name and type.
This code has worked in the past, but I've been hammering on my site
getting it "updated" and now it streams the word "None" every time.
If I stop and debug the buffer, I can see about 97K worth of text queued up
and ready to go. I've stepped it as far as the Response.stream() method
and everything looks perfect. But when the rubber hits the road, all I get
is "None". Here is the my code:
def _reg_getfile(now,idset):
from regexport import generate_regfile
from cStringIO import StringIO
buf = StringIO()
generate_regfile(idset, buf)
buf.seek(0)
response.headers['Content-Type']='application/sd3'
response.headers['Content-Disposition']='attachment;
filename=reg-%s.sd3'%now.strftime('%y%m%d-%H%M%S')
return response.stream(buf)
And my response in a file named reg-160911-023542.sd3:
None
Help me prevent baldness here. Because I'm sure I'm going to tear my hair
out over this!
I'm using "Version 2.14.6-stable+timestamp.2016.05.09.19.18.48" and Python
2.7.12 on a Mac under El Capitan (OS X ver. 10.11.6)
