The problem is of course that there's more than one child for each
parent, so you can't just display a simple 'age' field.
What you can do is provide a method that will concatenate the ages of
all the children related to that parent.
class Parent(models.Model):
....
def children_ages(self):
return u', '.join([c.age for c in self.child_set.all()])
children_age.short_description = 'Ages of children'
and in the admin class:
change_list = [name, children_ages]
