Merci AlexI'll have to try what you suggest - not with pandas because the csv
part is working well - but perhaps assembling the response as a separate object
and then trying to redirect back to the same URL. Might have to look at the
Django source and try to comprehend what it is doing.CheersMike--(Unsigned mail

I wonder if someone can point out my mistake?
The following code happily downloads a constructed text file ...
csv = make_csv(context['result'])
# This downloads a csv file to the user desktop
return HttpResponse(
csv,
headers={
'Content-Type': 'text/plain',
# Set the content-disposition header to prompt user download
'Content-Disposition': f'attachment; filename="{fname}.csv"'
},
)
... but leaves all the entered (unbound) form data on display.
However, I want the form cleared ready for the next set of user
data.
The following code clears the entered data but fails to download the
constructed file.
csv = make_csv(context['result'])
# This fails to download a csv file
return HttpResponseRedirect(
"",
csv,
headers={
'Content-Type': 'text/plain',
# Set the content-disposition header to prompt user download
'Content-Disposition': f'attachment; filename="{fname}.csv"'
},
)
Many thanks for any help
Cheers
Mike
