class MyModelAdmin(ParanoidAdmin):
    pass
  ...
admin.site.register(MyModel, MyModelAdmin)

m = MyModel.objects.last()
m.delete()

This only applies soft delete, so the record will remain in the database, but it will not be visible for normal queries:

m = MyModel.objects.last()
>>> m
>>>

Now the record has a deleted_at field and if do you want show the delete record you could using 'objects_with_deleted':

m = MyModel.objects_with_deleted.last()
>>> m
<MyModel: name>
>>> m.deleted_at
datetime.datetime(2019, 8, 10, 6, 16, 44, 633727, tzinfo=<UTC>)

On object which was soft deleted, follow steps above to restore object

m.restore()

If do you want to delete record from DB, you only should using True param:

m = MyModel.objects.last()
m.delete(True)
