Another approach would be to add a method to your events model. Name
it something like "current_occurrences" and have it return the
filtered occurrences. Ex:
class event( models.Model ):
...
def current_occurrences( self ):
return
self.occurrence_set.filter( date__gte=datetime.datetime.today() )
Then you would change your template to
{% for occurrence in event.current_occurences %}
That should offer a little better performance since you wouldn't be
pulling the entire occurrence set for each event.
If performance is a major factor, investigate writing a custom model
manager for your events model. That might be the best option for
retrieving the joined set of events with current occurrences in one
fell swoop in a nice abstracted manner.
