It feels like what you want is a custom manager function; you could
define a manager class for the model and leave the built-in methods
alone, then add a new method which does the query you want.
Something like this (rough first attempt) might work:
class GetNextManager(models.Manager):
def get_next_by_id(self, obj):
next_queryset = self.filter(id__gt=obj.id)
if next_queryset.count() > 0:
return next_queryset.order_by('id')[0]
return None
This queries the number of objects with ids higher than the one you
pass in; if there are any, it queries for and returns the one with the
lowest id. Otherwise it returns None, which will let you do boolean
tests to see whether you got an object out of it.
