Read file first and then send it in response.
from django.http import HttpResponse, HttpResponseNotFound
def waprfile(request, date):
...
file_location = '/path/to/file/foo.xls'
try:
with open(file_location, 'r') as f:
file_data = f.read()
# sending response
response = HttpResponse(file_data, content_type='application/vnd.ms-excel')
response['Content-Disposition'] = 'attachment; filename="foo.xls"'
except IOError:
# handle file not exist case here
response = HttpResponseNotFound('<h1>File not exist</h1>')
return response

If you want to return an image donβt forget to format it as png or jpeg and return the bytes with getvalue()
img = "Suppose I am a pil image"
fomatted_img = BytesIO()
img.save(fomatted_img, format="png")
response = HttpResponse(fomatted_img.getvalue(),content_type='image/png')
response['Content-Disposition'] = 'attachment; filename="output.png"'
return response
Or you can save the formatted image directly into the response
img = "Suppose I am a pil image"
response = HttpResponse(content_type='image/png')
response['Content-Disposition'] = 'attachment; filename="output.png"'
img.save(response,"PNG")
return response
