i need add function models, can´t how recognize model "this" scope variable. function model can reseted defaults , data-object parameter: backbone.model.prototype.reset = function( data ){ this.set(this.defaults); $.each( data, function( key, value ){ this.set( key, value ); }); } your code seems legit. value of this defined @ runtime , depends on how call method. if use modelinstance.reset() value of this modelinstance . however, mutating prototype of 3rd party considered bad practice should avoided. better practice create abstract model , have of model implement it. it like: var abstracrtmodel = backbone.model.extend({ reset: function (data, options) { this.clear(options); this.set(_.defaults({}, data || {}, this.defaults || {}), options); } }); the api of model.set permits passing data hash, don't need inner loop.

let's i'm working lua library installed using luarocks, , want see definition of function library. in ipython in use ??function_name to see definition in terminal, in matlab use which function_name then use editor @ path returned which. how similar find function definition lua library? in 'plain' lua/jit, can debug.getinfo ( func ) , table containing (among others) fields short_src , source , linedefined . for lua functions, short_src filename or stdin if defined in repl. ( source has different format, filenames prefixed @ , = prefix used c functions or stuff defined interactively, , load ed functions, actual string loaded.) you can pack in function like function sourceof( f ) local info = debug.getinfo( f, "s" ) return info.short_src, info.linedefined end or maybe start editor , point there, e.g. (for vim) function viewsource( f ) -- info & check it's file local info = debug.

i'm beginning work angularjs , having trouble working local copy of angular.js file. below sample trying work. when reference cdn script, page correctly displays 'hello, world'. when reference local script, binding not occur. browser able locate local angular.js file, doesn't seem perform binding. <html ng-app> <head> <title></title> <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.4/angular.js"></script> <!--<script src="scripts/angular.js"></script>--> <script> function hellocontroller($scope) { $scope.greeting = { text: "hello" }; } </script> </head> <body> <div ng-controller="hellocontroller"> <p>{{greeting.text}}, world</p> </div> </body> </html> if starting out 1.3.15 this: <html ng-app="main.app">

i'm trying generate query following via knex.js: insert table` ("column1", "column2") select "someval", 12345) not exists ( select 1 table "column2" = 12345 ) basically, want insert values if particular value not exist. knex.js doesn't seem know how this; if call knex.insert() (with no values), generates "insert default values" query. i tried following: pg.insert() .into(tablename) .select(_.values(data)) .wherenotexists( pg.select(1) .from(tablename) .where(blah) ); but still gives me default values thing. tried adding .columns(object.keys(data)) in hopes insert() honor that, no luck. is possible generate query want knex, or have build raw query, without knex.js methods? i believe select needs passed insert: pg.insert(knex.select().from("tablenametosel

alright, i'm new @ coding in c , have lot of copy , paste in code. (it's final project, don't have time optimize , shorten until end if time permits). anyway, i'm gonna avoid posting code reason. i'm gonna post relevant part i'm trying do. i need game pick random number 1-9 , use number select move on board. added printf in part of code make sure number being picked, when go scanf, game gives blinking prompt , not continue. does see wrong or need post other section of code? appreciated!! have included 1 player portion of game , when computer supposed move. removed win checks , re printing of board. let me know if guys need see else didn't want have huge block of code. if (player == 1) { for(k=0;k<9;k++) // 9 moves max. { printf("\n\n"); // print board again. printf(" %c | %c | %c\n", board[0][0], board[0][1], board[0][2]); printf("---+---+---\n"); printf(" %c
