ok, here is my new function:
def make_history(obj, function, s_time = 'none', sid='none', switch='none'):
print '\n\n make history'
print 'found object %s' % obj.monitor
print 'found raw = %s' % obj.last_raw
print 'type of raw = %s' % type(obj.last_raw)
print 'found value = %s ' % obj.last_value
store = Store.of(obj)
raw = float(obj.last_raw)
hit = HistoryHit()
hit.monitor = obj.monitor
hit.raw = raw
hit.value = unicode(obj.last_value)
hit.function = unicode(function)
if s_time == 'none': hit.s_date_time = datetime.datetime.now()
hit.date_time = datetime.datetime.now()
hit.sid, hit.switch = unicode(sid), unicode(switch)
store.add(hit)
the print statments show me that in my test, the raw was a type float
before the line that makes it one.
but i left the line that makes it a float in there anyway.
raw = float(hit.raw)
then later
hit.raw = raw
but still, the only thing showing up in the history table is 0 ( the default
)
and the DEBUG of the sql statement is still missing the raw as part of what
gets
INSERT INTO history..
thanks
