I\'m sure I\'m miss understanding the use of call but I thought I could do something like this.
@case_studies = CaseStudy.call(\"some_named_scope\")
To have an extra layer of security on top of the whitelisting BookOfGreg suggested, use public_send instead of send, it'll only work calling methods of the public interface, while send can reach even private methods.
send
So:
CaseStudy.public_send(:some_scope)
