javascript - What would be a good approach for providing d3 capability in a dust-helper? -

-

right i've been considering writing dust-helper renders barcharts dust files server-side using custom dust-helper , d3 module node. wondering if there better way construct sort of context object pass dust renderer:

{   padding: {     top: integer,     right: integer,     bottom: integer,     left: integer   },   width: integer,   height: integer,   data: [datum, ...],   x: {     scale: {       type: string, // 'linear', 'time', 'ordinal'       range: 'extent', // optionally [lower, upper]       tick: { // if applicable         format: string, // d3 number format linear scale                         // d3 time format time scale         args: integer | [interval, integer]       }     },     value: string, // datum[value] used x-axis   },   y: {     ...   } }

and on, have d3 use scheme render customized components , return svg markup string. seems verbose option me, lot of requirement add more , more attributes bloat context until becomes messy manage well, why wondering if there better approach perhaps splitting dust helpers individual components of d3.

i've been thinking , best way think go using d3 dust filter instead following:

dust.filters.d3 = function(value) {     var node = d3.select(value).node();      if (node) {         return node.outerhtml;     }      return 'd3 selection not found'; };

and running d3 code before starting dust rendering.

i have seen instructions on running cron in advanced template, cant figure out how on basic template. have following controller in basic controllers folder. <?php namespace app\controllers; use yii\console\controller; /** * cron controller */ class croncontroller extends controller { public function actionindex() { echo "cron service runnning"; } public function actionmail($to) { echo "sending mail " . $to; } } i have navigated root of application , tried these comands yii cron php yii cron im getting unknown comand "cron" i know old question failed find actual answer this. if @ code yii exec file you'll notice requires /common/config/aliases.php file console/config/main.php. can naturally change these or copy on these advanced template. hope solves problem wanting same thing.

asp.net - 'System.Web.HttpContext' does not contain a definition for 'GetOwinContext' Mystery -

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
