javascript - AngularJS : Bind to transclusive directive without isolating the scope -

-

let's have angular markup like:

<custom bindto="modelproperty">     <!-- trascluded content. --> </custom>

would possible custom directive bind using bindto attribute, allowing properties accessible transcluded content, without isolating scope of custom? basically, want directive bind custom part of model without cutting off scopes of parents , without having add code like:

scope.prop = scope.$parent.prop;

any ideas?

edit imagine structured http://plnkr.co/edit/zq2oo1?p=preview, except working , without isolate scope.

by using scope: true can maintain access parent scope's properties via prototypical inheritance while maintaining unique scopes each instance of directive (ie. reusable). (note: make sure observe the dot rule models need change on parent scope within transcluded content)

you'll need call transclude function compile function, passing directive's scope first argument in order link transcluded content against it.

it might this:

.directive('custom', function() {   return {     restrict: 'e',     transclude: true,     scope: true,     link: function(scope, elem, attrs, ctrl, transclude){        scope.bindto = scope[attrs.bindto];       transclude(scope, function(clone){         elem.find('ng-transclude').replacewith(clone);       });     },     template: '<div>from parent scope: <i>{{somevar}}</i> <ng-transclude></ng-transclude></div>'   } });

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
