Overriding Rails Error (Validation) Messages from Gems/Plugins -

-
is there accepted way of overriding error (validation) messages gem/plugin in rails? for example, i'm using activemerchant gem, , if puts in american express credit card number, selects 'mastercard', not-very-descriptive "type not correct card type" error. i can around doing this: def validate_card unless credit_card.valid? credit_card.errors.full_messages.each |message| if message =~ /is not correct card type/i errors.add_to_base "this credit card number invalid. please ensure selected correct type." else errors.add_to_base message end end end end but technique becomes unmaintainable , (at least in opinion) far 'best-practices'. similarly, unpack activemerchant gem , hack put in own custom error messages, seems unmaintainable require same hacks added future, unpacked, versions of activemerchant. in honesty, you're best bet either rewrite parts ...

Navigation menu with highlight in Asp.NET MVC? -

it's simple question. how did stackoverflow menu in asp.net mvc, highlight on page on . there no mvc special magic makes happen. i'm sure: if( httpcontext.current.request.path == "some menu url" ) or if( viewcontext_or_controllercontext.routedata.values["controller"] == "some value") is used someplace. you put code in 3 different locations ( view ( .aspx ), viewmodel, custom htmlhelper ) , require same bit of code.

C interview question---run-length coding of strings -

a friend of mine asked following question yahoo interview: given string of form "abbccc" print "a1b2c3". write function takes string , return string. take care of special cases. how experts code it? thanks lot there's more 1 way it, i'd run on input string twice: once count how many bytes required output, allocate output buffer , go again generate output. another possibility allocate front twice number of bytes in input string (plus one), , write output that. keeps code simpler, potentially wasteful of memory. since operation looks rudimentary compression (rle), perhaps it's best first implementation doesn't have output occupy double memory of input. another possibility take single pass, , reallocate output string necessary, perhaps increasing size exponentially ensure o(n) overall performance. quite fiddly in c, not initial implementation of function, in interview conditions. it's not faster first version. however it...

i have 2 separate renderers, 1 1.1 , 2.2 i have bunch of item s hold image information , texture handle generated whichever renderer using. items dumb objects , don't want introduce opengl specific functionality them. problem is, need store texture handle somewhere. store inside each item , handle of type gluint . if use gluint means including either gl.h es1/ or es2/. both typedef'd unsigned ints... ok use unsigned int? seems bad practice... example if opengl 3.0 came out , gluint different, item broken. any ideas? thanks reading. subsequent versions of opengl supersets of previous versions. opengl specific types meant hide underlying systems consistent across versions. example if have int 16 bit gluint might defined unsigned long . therefore say: go smallest common denominator (es1.1).

c++ - Checking if an iterator is valid -

is there way check if iterator (whether vector, list, deque...) (still) dereferencable, i.e. has not been invalidated? i have been using try - catch , there more direct way this? example: (which doesn't work) list<int> l; (i = 1; i<10; i++) { l.push_back(i * 10); } itd = l.begin(); itd++; if (something) { l.erase(itd); } /* now, in other place.. check if itd points somewhere meaningful */ if (itd != l.end()) { // blablabla } i assume mean "is iterator valid," hasn't been invalidated due changes container (e.g., inserting/erasing to/from vector). in case, no, cannot determine if iterator (safely) dereferencable.

asp.net mvc - Keeping a controller thin (too many action methods) -

i'm working on first real asp.net mvc project , i've noticed controller i've been working in getting rather large. seemingly goes against best practice of keeping controllers thin. i've done job keeping business logic out of controllers. use separate layer that. each action calls method in business layer , coordinates end result based on whether or not modelstate valid. that said, controller has large number of action methods. intuitively, break controller down sub-controllers don't see easy way that. break controller down separate controllers loose hierarchy , feels bit dirty. is necessary refactor controller large number of thin actions? if so, best way this? first, when hear it's keep controller code minimum, refers keeping each action method thin possible (put logic instead business classes, not views , viewmodels.) seems you're doing this, great. as having "too many" action methods, judgment call. sign of organiz...

php - Automatic update of MYSQL table according to date -

i have mysql table holds events information. need mechanism updates status of each event according date ("over" if past date). what´s best way such thing? update status of event when user logs in (useless routine users), create sort of internal task (like cron job?), or other way. right now, status of event updated when creator logs in. works user see event "scheduled" until creator logs in, if date past. im using php way. thanks i recommend updating status time status requested. or better yet, don't store status in database @ all, compute each time it's requested based on other variables. way whenever have table list status or request status, take event date, compare today's date, , send them "not started", "ongoing", or "over". unless of course need more possible statuses ("planning", "preparing", "setting up", etc). either need scheduled dates/times each of these statuses or ...

if @ php doc function session_cache_limiter() , see if cache_limiter parameter set private or nocache expires http header set const date (thu, 19 nov 1981 08:52:00 gmt). understand date in past avoid caching, why date/time in particular? it's not 0 date, guess kind of easter egg. if it's kind of dummy value in past, can change else (still in past) , still have private/nocache mechanism still working? it birthday of person contributed code: diffs: http://cvs.php.net/viewvc.cgi/php-src/ext/session/session.c?r1=1.80&r2=1.81 http://www.phpbuilder.com/lists/php3-list/199911/3159.php to change it, preferable set headers manually, example nocache sets this: expires: thu, 19 nov 1981 08:52:00 gmt cache-control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 pragma: no-cache but still do: session_cache_limiter('nocache') header('expires: thu, 1 jan 2000 00:00:00 gmt'); header replace existing header same name (by default). ...

JavaScript constructors -

-
i not understand quite how apply constructors on object creation method: var myobject = { ... }; i know can do: var myobject = new object(); myobject.prototype.constructor = function(props) { ... } or... function myobject(prop1, prop2) { this.prop1 = prop1; ... } can this? var myobject = { myobject: function(prop1, prop2) { ... } } no, can't, create (static) method on myobject -- myobject.myobject . in javascript, constructor is class. class methods , properties created either inside constructor using this. or adding prototype (outside of constructor) using myclass.prototype. . can think of "objects" in javascript static classes.
