Keeping DRY with custom Django templatetags

I have an existing templatetag, show_next_event:

def show_next_event():
    try:
        e = Event.objects.filter(published='1').order_by('date').filter(date__gte=datetime.date.today())[0]
    except IndexError:
        e = ''
    return {'event': e}
register.inclusion_tag('events/next_event.html')(show_next_event)

I'd like to abstract the template. First thing that comes to mind is to change show_next_event to just next_event and then add two new functions; show_next_event and show_next_event_badge. Im hoping I can do something like the following but it doesn't work as-is:

def next_event():
    try:
        e = Event.objects.filter(p开发者_如何学运维ublished='1').order_by('date').filter(date__gte=datetime.date.today())[0]
    except IndexError:
        e = ''
    return {'event': e}

def show_next_event():
    next_event
register.inclusion_tag('events/next_event.html')(show_next_event)


def show_next_event_badge():
    next_event
register.inclusion_tag('events/next_event_badge.html')(show_next_event_badge)

Or is there an even better solution?

Django is Python, not Ruby. You can't call a function just by specifying its name: you need to use the calling parentheses. And Python doesn't automatically return the value of the last expression in the function: you need to use the return statement.

So, this should work:

@register.inclusion_tag('events/next_event_badge.html')
def show_next_event_badge():
    return next_event()

Also, note that I've used the decorator syntax to register the tag.

After following @Daniel suggestions, you could do this to avoid the defs (DRY!) :

show_next_event = next_event
show_next_event_badge = next_event

EDIT:

It would be like this:

def next_event():
    try:
        e = Event.objects.filter(published='1').order_by('date').filter(date__gte=datetime.date.today())[0]
    except IndexError:
        e = ''
    return {'event': e}

show_next_event = next_event
show_next_event_badge = next_event

register.inclusion_tag('events/next_event.html')(show_next_event)
register.inclusion_tag('events/next_event_badge.html')(show_next_event_badge)
