angularjs - Angular.js service return $http success data -

in app, want create service looks in backend check if user logged in , returns user data , privileges. factory service looks this:

app.factory 'session', ['$http', ($http) ->   getsession: ->     $http.get("/admin/session") ] 

right now, handle success , errors service in controller shown below.

$scope.session = session.getsession()   .success((data) ->     # set logged in user     $scope.admin = data      # limit privileges            )   .error((data) ->     # logged in user not found rediret login screen     window.location = "/user/login"   ) 

my problem need repeat same code in lot of different controllers. there better way handle this? thinking might need $rootscope not understand how works.

you can put logic inside service itself. have use promises returning success data controller. controller, this:

   session.getsession().then(function(data){       $scope.admin = data;    }); 

and handle errors in service. note pseudo code.

app.factory 'session', ['$http', ($http) ->   getsession: ->     return $http.get("/admin/session")            .success(data){}            .error(){ //... redirect user} ]
