how to import modul DJANGO in strategie?

mamos

hello all,
first I'm newbies and sorry for my English...
I have a big problem. It is impossible to import module from Django like models...
I don't understand why I can't do it.
please help me I will be crazy :'(

EXAMPLE:
from datetime import datetime
import backtrader as bt

FROM FOOAPP.MODELS IMPORT barstrategie

class SmaCross(bt.SignalStrategy):
def init(self):
sma1, sma2 = bt.ind.SMA(period=10), bt.ind.SMA(period=30)
crossover = bt.ind.CrossOver(sma1, sma2)
self.signal_add(bt.SIGNAL_LONG, crossover)

cerebro = bt.Cerebro()
cerebro.addstrategy(SmaCross)

data0 = bt.feeds.YahooFinanceData(dataname='YHOO', fromdate=datetime(2011, 1, 1),
todate=datetime(2012, 12, 31))
cerebro.adddata(data0)

cerebro.run()
cerebro.plot()

DJANGO RETURN No module named ''FOOAPP"
