- Extend “destroy_if” to accept a Proc which returns either true or false as well Oops, that’s wrong, I mean “extend the allow_destroy option” of course.
Not too many opinions thus far. 
It basically boils down to this: Should the reject_if option only be relevant for creates and updates or for deletes as well?
I tend towards “yes”, but a patch for this will change the behaviour of allow_destroy in conjunction with reject_if. Such an API change might cause headaches on existing applications. (A temporary warning if both options are set might be useful.)
Opinions anyone?
