i'm newby in symfony, excuse ignorance. in project use sonata user bundle, user entity extended several fields. of them can edited user himself, while others serviceable , can edited admin. question is: how ensure security when editing information user? see 2 ways: 1. use custom validation constraints check user's role. 2. use one-to-one related entity own admin. perhaps there standard ways accomplish task? thanks in advance! upd: problem there 1 entity (user) can edited different places: admin area , public area. naturally, forms admin , public areas different, there possibility attacker can forge form , edit fields accessible administrator. therefore, want protect them @ level of entity. possible? there many cases of security. can use @security has_role('role_admin') annotation action or in twig is_granted display or not field or use custom voter check if user can edit or delete un objet @ this. describe need you.

i have (in past) written cross-platform (windows/unix) applications which, when started command line, handled user-typed ctrl - c combination in same way (i.e. terminate application cleanly). is possible on windows send ctrl - c /sigint/equivalent process (unrelated) process request terminate cleanly (giving opportunity tidy resources etc.)? the closest i've come solution sendsignal 3rd party app. author lists source code , executable. i've verified works under 64-bit windows (running 32-bit program, killing 32-bit program), i've not figured out how embed code windows program (either 32-bit or 64-bit). how works: after digging around in debugger discovered entry point behavior associated signal ctrl-break kernel32!ctrlroutine. function had same prototype threadproc, can used createremotethread directly, without having inject code. however, that's not exported symbol! it's @ different addresses (and has different names) on different versions...
