created but could not use the instace filter

def send_sms_notifications(sender, instance, created, **kwargs): #get
sender, instance, created
# TODO: Lookup the reporters based on the sample point and
# figure out who to send to, what to send
# print sender.notes
reporter = instance.taken_by
point = instance.sampling_point
# A temporary SMS Response
# TODO: Auto generate response SMS.
msg = "Your sample data is submitted sucessfully.!"
# sending an sms to a submitter.
thread = Thread(target=_send_sms,args=(reporter.id, msg ))
thread.start()
# create massage for the authorised testers.
msg2 = "Test taken at site %s - %s." %
(instance.sampling_point.wqmarea, instance.sampling_point)
# ss =
Sample.objects.filter(taken_by=reporter,sampling_point=instance.sampling_point,
date_received=instance.date_received)
# The instance is displayed here.
print '############### %s ########' % (instance)
# I can get the instace id. OK
print '<<<<<<<<<<<<<<<<<<< %d' % (instance.id)
sample_id = instance.id
m_values = MeasuredValue.objects.filter(sample__id = sample_id)
# I NEED TO GET MEASUREDVALUE WITH RESPECT TO THE SAMPLE
# NO DATA IS RETURN HERE...
print '----------------- %s ' % (m_values)
for m_value in m_values:
print "<<<<<<<<<<<<<< %s:%s" % (m_value.parameter.test_name,
m_value.value)
msg2 += " %s:%s" % (m_value.parameter.test_name,
m_value.value)
msg2 += '. Comment: %s'%(instance.notes)
# figure out who to send sms to in the notifation table.
notices = SmsNotification.objects.filter(sampling_point = point)
for notice in notices:
reporter = notice.authorised_sampler
# TODO: generate a sms according the the authorised tester.
# this is temp sms to authorised sampler
# send the sms
thread = Thread(target=_send_sms,args=(reporter.id, msg2 ))
thread.start()
def _send_sms(reporter_id, message_text):
data = {"uid": reporter_id,

}
encoded = urllib.urlencode(data)

try:
conn = httplib.HTTPConnection("localhost:8000") # TODO: DON'T
HARD CODE THIS!
conn.request("POST", "/ajax/messaging/send_message", encoded,
headers)
response = conn.getresponse()
except Exception, e:
