in django, django's update_object general perspective correct forms hereditary models?

in django, given excerpts an concentration animals likeso:

a animals/models.py with:

from django.db import models
from django.contrib.contenttypes.models import contenttype

class animal(models.model):
  content_type = models.foreignkey(contenttype,editable=false,null=true)
  name = models.charfield()

class dog(animal):
  is_lucky = models.booleanfield()

class cat(animal):
  lives_left = models.integerfield()

and an animals/urls.py:

from django.conf.urls.default import *

from animals.models import animal, dog, cat

dict = { 'model' : animal }

urlpatterns = (
  url(r'^edit/(?p<object_id>\d+)$', 'create_update.update_object', dict),
)

how general views correct dog and/or cat controlling same form?

i.e. form vigilant upheld animals/animal_form.html animal, so won't enclose any specifics subsequent classes dog cat. i have django automatically pass form child category animal/animals_form.html?

incidentally, i'm controlling contenttype management, animal have slight named as_leaf_class advantage subsequent class.

clearly, emanate forms any subsequent class, nonetheless that's definitely lot low duplication (as templates general -- radically {{ form.as_p }}).

incidentally, it's best assume animal substantially several separate bottom classes same problem, an ideal fortitude generic.

thank lay help.
