I have read the docs at:
http://docs.djangoproject.com/en/dev/topics/serialization/#inherited-models
That offer the following example for inherited serialization:
class Place(models.Model):
name = models.CharField(max_length=50)
class Restaurant(Place):
serves_hot_dogs = models.BooleanField()
all_objects = list(Restaurant.objects.all()) + list(Place.objects.all
())
data = serializers.serialize('xml', all_objects)
This works properly if I only have one class (Restaurant) inheriting
from my base model of Place. However, if I have a second class, say:
class BurgerStand(Place):
patty_size = models.FloatField()
Then if I try:
all_objects = list(BurgerStand.objects.all()) + list(Place.objects.all
())
data = serializers.serialize('xml', all_objects)
I get all Place objects - even the ones that are not related in any
way to BurgerStand. Of course I also no longer get the correct
results for my Restaurant query either. Is there a way to have the
serializer properly traverse the inherited relationship in a way that
I only get the appropriate results in my serialized result?
Thanks.
