your right, i probably should seperate the hits better. the module that contains my make_history function i did not want to have to create a store for each time one of the functions operated, so i use the store of the object that i pass into it from my main thread. def do_some_thing_with_object( obj ):    store = Store.of(obj) this allows me to use the store that was created in the main thread. i will try again with renamed variables. Maybe the values are not maintained well because of the way i have them. Since the same store had a hit in it that represented a StatusHit and one that represented a HistoryHit. that kinda still wouldn't explain why raw is the only one that does not get updated. but i am still new to a lot of this. thanks shawn    <div> On 8/7/07, Adrian Klaver <<a href="mailto:aklaver@comcast.net">aklaver@comcast.net</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> On Tuesday 07 August 2007 4:00 pm, shawn bright wrote: > 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) Alright, I am now officially lost. Where did this line come from?

If it where me I would try store=Store(). Also we are not seeing all the code and in your examples you call self.store before running make_history so it is entirely possible you need to drop the store assignment and just do self.store.add(hit). Something else comes to mind, in your examples you assign to hit for values going to StatusHit() and for values going to HistoryHit(). Having wrestled with name visibility before, I generally try to create different names to make it easier to sort out where my values are originating from i.e. status_hit,history_hit Good luck, -- Adrian Klaver <a href="mailto:aklaver@comcast.net">aklaver@comcast.net</a> </blockquote></div>
