if i get you right, you could accomplish this by using a model method

get_weather(self):
 weather = Weather.objects.filter(weather_date=self.created, ...

cheers, chr

I did that:

   def get_weather(self):

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

        return weather

and it seems to work. (no errors, I can iterate through weather, in models.py)  But when I try to access it in the template:

{% for note in notes %}

 <div class="note">

  {{note.get_weather}}

is the only thing that will work - it returns the unicode object:

([<Weather: Sunny>])

If I try to get a value from the Weather model {{note.get_weather.condition}} -  nothing.

I'm clearly not understanding what's getting returned.

I looked at some other code that uses model methods (django-articles, in this case) and that syntax seems to be what is used.

I'm grateful for anymore pointers.
