Angularjs directive conditional rendering without ng-if -

-

i have directive render if authentication service tells me so:

<div my-loggedin-directive ng-if="security.isauthenticated()"></div>

the directive quite empty :

.directive('myloggedindirective', [     function() {         return {             templateurl: 'modules/myloggedindirective.tpl.html',             restrict: 'a',             replace: true,             link: function($scope) {                  $scope.$on('$destroy', function() {                      console.log('$destroy');                  });             }         };     } ]);

since directive should rendered when i'm logged in, ngif logic should inside directive declaration, , not in ng-if (the directive without ngif totally broken).

how can change directive code (injecting test on security service inside directive declaration) knowing want same behavior ngif ? :

  • directive present in dom when nfif resolves true
  • automatic calling of $destroy when nfif resolve false) ?

i tried use compile function , watcher watch security.isauthenticated() without success

declare directive attribute pass security object directive:

<div my-loggedin-directive my-security='security'></div>

and directive should include scope, make sure uses two-way binding:

.directive('myloggedindirective', [ function() {     return {         scope: {             security: "=mysecurity"         }         templateurl: 'modules/myloggedindirective.tpl.html',         restrict: 'a',         replace: true,         link: function($scope) {              $scope.$on('$destroy', function() {                  console.log('$destroy');              });               $scope.$watch('security', function(newval, oldval) {                  if (newval.isauthenticated()) {                  //                  } else {                  //                  }              });         }     }; }

]);

and can access $scope.security variable in temple myloggedindirective.tpl.html

<div ng-if="security.isauthenticated()">...</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()

-
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...
