How to do reverse lookup of foreign keys with Python Django?

To do reverse lookup of foreign keys with Python Django, we can use the filter method.

For instance, we write

def detail(request, venue_id):
    venue = Event.objects.filter(venue__id=venue_id)
    return render(request, 'venue-detail.html', {'venue': venue})

to look up the Event objects by the venue_id with filter.

And then we render the values in the venue-detail.html.
