i just want to do it automatically, dont want to press F12 then double click so the browser can download it
Francisco Ghelfi :
You are not setting correctly the content_type.
response = HttpResponse(content_type='text/plain')
And also setting the filename as TXT instead of CSV
response['Content-Disposition'] = 'attachment; filename="somefile.txt"'
The following code works just fine for me.
import csv
from django.http import HttpResponse
def CsvOutputView(request):
response = HttpResponse(content_type='text/csv')
response['Content-Disposition'] = 'attachment; filename="somefilename.csv"'
writer = csv.writer(response)
data = your_model.objects.all().values_list()
for this_data in data:
writer.writerow(this_data)
return response
Hope it helps.
