Re: Four Hop, Two Criteria Query

Just be careful with the index errors. If you are sure that this query will allway have at least one item, so this is fine. But if it returns an empty queryset, so you will have trouble with IndexError.

weather = Weather.objects.filter(weather_date=self.target_date,zip_code=self.created_by.store.zip_code)    

so, the solution was

  def get_weather(self):
        weather = Weather.objects.filter(weather_date=self.target_date,zip_code=self.created_by.store.zip_code)[0]                
        return weather

just return a single record....
