varApp = Angular.module (' app ', []); App.controller (' Mainctrl ',function() {  varCurrentUser ={rights: []}; functionsetadmin () {resetadmin (); CurrentUser.rights.push (' Admin '); }  functionresetadmin () {currentuser.rights= []; }   This. CurrentUser =CurrentUser;  This. Setadmin =setadmin;  This. Resetadmin =resetadmin;}); App.filter (' User ',function(){  varRules ={isadmin:function(user) {returnUser.rights.indexOf (' admin ')!==-1; }, Isntadmin:function(user) {return!rules.isadmin (user);    }  }; return function(user, rule) {returnRules[rule] (user); };});
