Django reverse lookup of foreign keys
Go the other way round. Use Event
model.
def detail(request, venue_id):
venue = Event.objects.filter(venue__id=venue_id)
return render(request, 'venue-detail.html', {'venue': venue})
PS: I have never used get_object_or_404()
. Modify code accordingly.
You can use events = venue.event_set
to go the other way.
Note that venue.event_set
is a manager object, like Event.objects
, so you can call .all
, .filter
, .exclude
and similar on it to get a queryset.
See the Django documentation
To those who have "'RelatedManager' object is not iterable"
Add all to retrieve the elements from the manager.
