how to override the verbose name of a superclass model field in django

A simple hack I have used is:

class SuperFoo(models.Model):
    name = models.CharField('name of SuperFoo instance', max_length=50)
    ...
    class Meta: 
        abstract = True

class Foo(SuperFoo):
    ... # do something that changes verbose_name of name field of SuperFoo
Foo._meta.get_field('name').verbose_name="Whatever"
