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

i have modelform has unique_together constraint on fields. when pass data form , call form.is_valid(), returns false if record exists , if other error occurs. so, want in case record exists(unique_together validation fails) , thing in case form.is_vaid() returns false due other reasons. how achieve ? it have modelform code , traceback errors in both cases give more accurate answer, workaround parse form.errors, corresponding type error or message error , write corresponding code. ps : message should comment under post lack few reputation points, sorry that.

is possible have imacros script force firefox stop loading page after executed previous command. set !timeout_step 1 set !errorignore yes tag pos=1 type=input:submit form=id:flg-addspray attr=name:submit wait seconds = 10 [stop page load] [next commands] for whatever reason, script gets stuck after submit button executed, never loads next page, or gets stuck on next page. , script halts not moving along long string of commands. it's in loading infinite loop. want stop. , move on. i think should use built-in variable !timeout_page : set !timeout_step 1 set !errorignore yes set !timeout_page 15 tag pos=1 type=input:submit form=id:flg-addspray attr=name:submit set !timeout_page 60 wait seconds = 10

i have edited 2 strings , can covert them character maps. trying think through best way map , replace based off of these 2 strings. example: have word append front of alphabet based on user input. in example cat(catdefghijkl..). take sentence , replace characters in based on new alphabet. (now c, b a, c t). not looking code input on best way accomplish this. can map 2 strings or character maps , replace based on mappings? you can use map<character, character> . the key regular alphabet letter, , value new letter. map<character, character> newalphabet = new hashmap<>(); list<character> regularalphabet = arrays.aslist('a', 'b', 'c');//put complete alphabet here public void updatealphabet(list<character> newletters) { assert (newletters.size() == 26);//or 52 uppercase atomicinteger = new atomicinteger(0); newalphabet.clear(); regularalphabet.stream() .foreach(letter -> newalphabet.put(le
