Sorting related items in a Django template

Question

Is it possible to sort a set of related items in a DJango template?

That is: this code (with HTML tags omitted for clarity):

{% for event in eventsCo         


        

Answer 1

You need to specify the ordering in the attendee model, like this. For example (assuming your model class is named Attendee):

class Attendee(models.Model):
    class Meta:
        ordering = ['last_name']

See the manual for further reference.

EDIT. Another solution is to add a property to your Event model, that you can access from your template:

class Event(models.Model):
# ...
@property
def sorted_attendee_set(self):
    return self.attendee_set.order_by('last_name')

You could define more of these as you need them...
