django extend ModelAdmin fieldsets and keep defaults

Question

is there a nice way to add custom items to a subclassed ModelAdmin fieldset, ie have it keep all the defaults and just some extras.

(i know i could add all the defaults back myself, but was hoping for a nicer way)

Answer 1

Untested, but may work:

class MyAdmin(BaseAdmin):
    fieldsets = BaseAdmin.fieldsets + (...)

This would (if it works) add the other fieldsets after the inherited ones.
