admin.display decorator boolean flag not working with @property

[Ronny Vedrilla]

Hi guys,

I really hope that I'm not missing anything.

I have a model with a boolean property I'd like to show in my admin list view:

class MyModel(models.Model):
    ....

    @property
    @admin.display(description=_('Is external'), boolean=True)
    def is_external(self):
        return bool(self.requested_external)

My admin column shows True and False strings instead of the green and red icons.

When I remove the property decorator, it works as expected.

I double-checked the docs but couldn't find any note about not using it with properties.

Thanks!

Yes, boolean doesn't work for properties. It's a duplicate of #31558.

Ok, I searched the database for django 3.2 issues (because the decorator was added there - thats why I didnt find it. Sorry.
