How to use can_add_related in Django Admin

Question

I've read about the can_add_related feature here: https://code.djangoproject.com/ticket/9071

I tried using it this way:

def get_form(self, request, obj=None, **kwargs):
    self.fields['person'].can_add_related = False
    return super(OperationAdmin, self).get_form(request, obj, **kwargs)

But this throws a TypeError and I don't know how to solve this.

Can someone point me in the right direction?

Thank you.

This is probably coming in late. But for other viewers reference,

def get_form(self, request, obj=None, **kwargs):
    form = super(ProductAdmin, self).get_form(request, obj, **kwargs)
    form.base_fields['category'].widget.can_add_related = False
    return form
