I have a table in which I have a blob column containing some data, how can i download the blob content in django? I tried the solution mentioned here but it didn't work for me
def download_blob(request, id):
contents = BlobModel.objects.get(id=id).blob_field
response = HttpResponse(contents)
response['Content-Disposition'] = 'attachment; filename=blob.bin'
return response
