Django admin listview column names

In Django's admin app, you can easily change what columns appear for a given model's list view. For example, if I have a "Manager" model and I want to display the number of underlings in their line item in admin, that's easy, assuming the model has a method to count up underlings (we'll say it does, Manager.underlings_count()):

class ManagerAdmin(admin.ModelAdmin):
    list_display = ('__unicode__', 'underlings_count')

But what if I don't want the column header to be called 'Underlings count'? The name is very descriptive and good in code, but in admin 'count' is just wasted space - if you're looking at a list of numbers, it's obviously a count.

The workaround to change it is super simple:

class ManagerAdmin(admin.ModelAdmin):
    list_display = ('__unicode__', 'underlings')

    def underlings(self, obj):
        # in this context, obj is the Manager instance for this line item
        return obj.underlings_count()

Boom. Retitled column just by defining a proxy function.
