Python HttpResponse.override_serialization Examples

Example #1

File: grapher.py Project: parisk/synnefo

def grapher(request, graph_type, hostname):
    hostname = decrypt(uenc(hostname))
    fname = uenc(os.path.join(settings.RRD_PREFIX, hostname))
    if not os.path.isdir(fname):
        raise faults.ItemNotFound("No such instance")

    outfname = uenc(os.path.join(settings.GRAPH_PREFIX, hostname))
    draw_func = available_graph_types[graph_type]

    response = HttpResponse(draw_func(fname, outfname), status=200, content_type="image/png")
    response.override_serialization = True

    return response
