Specify __str__() Representation in Django Admin list_display

Not sure if this is a good way to do things (this is more of a technical question), but what if I have a Django model with __str__ function that combines several fields:

def __str__(self):
    return f'{self.field0} {self.field1} {self.field2}'

In the admin, I might have the list_display like so:

list_display = ['field0', 'field1']

How do I specify this to use the object representation returned by the __str__ function?

list_display = [<__str__() representation>, 'field0', 'field1']

By default, if you don't specify list_display in the admin, it'll give me what I want. Can't I have both?

This can simply done by just adding list_display = ['__str__',] in the ModelAdmin class.

You can add callables to the list_display attribute [Django-doc], so you can add str:

def model_str(obj):
    return str(model_str)
model_str.short_description = 'Object'


class MyModelAdminAdmin(admin.ModelAdmin):
    # …
    list_display = [model_str, 'field0', 'field1']

this is thus a reference to the builtin str(…) function [python-doc].
