javascript - Loading one dataset using data from another in Angular $watch -


i creating messaging service needs following 1.) load messsage our messages service, recipient's ids, , load recipients' info users service. i've tried both using messages service callback, , creating watcher on message object, without success. service works, doesn't assign result $scope correctly. here's controller. of services working correctly:

function messagectrl ($scope, $http, $location, $routeparams, messages, members) {      if ($routeparams.mid) {  // checks id of message in route. otherwise, creates new message.         $scope.mid = $routeparams.mid;         $scope.message = messages.messages({mid: $scope.mid}).query();          $scope.$watch("message", function (newval, oldval, scope) {             if (newval.data) {                   $scope.recipients = members.members({uids: newval.data[0].uids}).query();             }         }, true);      } else {         $scope.create = true;     }      // events      $scope.save = function () { };     $scope.preview = function () { };     $scope.send = function () { };   }

the correct way use query perform action in callback passed in query function. in other words$scope.message should assigned in callback. don't need $watch. can call other service within callback directly. keep clean please use deferred
