Massimo,
Here is my code,
I use GUI button to start my service (StartEngine, in the background,
I want to retrieve the infomation from another application and save it
in my database for every couple of munites. after I starting my start
engine service, I can go to other screen. and the background service
keeps runing.
I can create the thread now, but got an error :SQLITE object created
in a thread can only used in that same thread.
def enginestart():
menu_setup()
# engine.start()
session.starttimer=True
symbols=db(db.symbols.id>0).select()
# for symbol in symbols:
# engine.addMarket(symbol.symbol_Name,
symbol.description,symbol.tick)
session.flash='engine stared'
session.enginestarted=True
db(db.historyprice.id >0).delete()
# tt=threading.Timer(2, gethistoryprice(db))
# tt.start()
t=Gethistoryprice()
t.start()
redirect(URL(r=request,c='engine',f='enginemaint'))
return dict() session.starttimer=True
symbols=db(db.symbols.id>0).select()
# for symbol in symbols:
# engine.addMarket(symbol.symbol_Name,
symbol.description,symbol.tick)
session.flash='engine stared'
session.enginestarted=True
db(db.historyprice.id >0).delete()
t=Gethistoryprice(db)
t.start()
redirect(URL(r=request,c='engine',f='enginemaint'))
return dict()
class Gethistoryprice(threading.Thread):
def __init__(self, db):
threading.Thread.__init__(self)
self.stopped=0
self.db=db
def run(self):
while not self.stopped:
mysym=self.db(db.symbols.id>0).select()
for symbol in mysym:
# p=engine.getlastprice(symbol)
p=random.randrange(10.00,60.00)
now=datetime.datetime.now()
db.historyprice.insert(symbol_Name=symbol.symbol_Name,
timestamp= now, price=p)
