After having had a go at tracing what's going wrong, I have kludged
together this solution to my problem by adding the following method to
the 'Child' class:
class Child(models.Model):
[...]
def set_toys(self, new_ids):
self.toys = [Toy.objects.get(id=new_id) for new_id in new_ids]
return True
Now everything seems to work fine. Note that the method returns True
because where it is needed in the django source it seems to expect a
boolean that says whether there was actually a change (I return True
because it's the simplest).
Is this a bug in django? If so please tell me where to report it.
Otherwise I'd be glad to learn how to do things the correct way.
