It seems it should be possible to update a resource from another site or email by issuing a post with the proper form data to the update url for the resource. It works from curl but not from the browser, as far as I can tell. If it is possible, is it possible to do it securely by accommodating protect_from_forgery?
Why? I'd like to be able to rsvp an event invitation without requiring people to login or be a member of the site.
Thanks
