AngularJS scope return $$state

AngularJS scope return $$state
I have a directive and in this directive I have a value that comes from my controller, here is my directive:
angular
.module('thermofluor')
.directive('tablePlate', tablePlate)
tablePlate.$inject = ['$timeout', '$q'];
function tablePlate($timeout, $q) {
var directive = {
link: link,
restrict: 'E',
templateUrl: '/crims/thermofluor/experiments/table_plate.html',
scope: {
plate: '='
}
};
return directive;
function link(scope, element) {
console.log("test");
var plate = scope.plate;
console.log(plate);
scope.letters = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H'];
scope.numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12];
experiments = ;
experiments[scope.plate.experiment.well] = [scope.plate.experiment];
return;
}
}
The problem is that when I console.log the scope I see my plate object with everything I need inside, but when I try to console.log the scope.plate object, the object change and it return me a $$state, and I don't know how to use this $$state
console.log
console.log
scope.plate
$$state
$$state
Anyone have an idea ?
scope.plate.then(function(res){ console.log(res) })
Is there any other solution more simple ? I'll need to access to my variable so much times

Promises are asynchronous callbacks, you don't know when the data will arrive: in just a few milliseconds, or in a minute. So you can't really assign the value to a variable (only a Promise). So you have to resolve it every single time. There is a hack, however, where you can assign it to a variable within
angular.config in your routes (ngRoute or ui.router) through resolve property.– Aleksey Solovey

angular.config
ngRoute
ui.router
Is this a good or bad way to put all my code inside the scope.plate.then(function(res){} ? With this method sometimes when I refresh the page is says cannot read property then of undefined, and when I refresh again it works

keeping everything in
.then is the way to go. If you have more than one promise to deal with, you need to chain them. (There are some ways you can avoid Pyramid callback hell by stacking .then().then()) Also if you have promises that you need to resolve at the same time without chaining, you can use $q.all() (it works similarly to Promise.all())– Aleksey Solovey

.then
.then().then()
$q.all()
Promise.all()

//use of the controller with scope will resolve your problem
angular
.module('thermofluor')
.directive('tablePlate', tablePlate)
tablePlate.$inject = ['$timeout', '$q'];
function tablePlate($timeout, $q) {
var directive = {
link: link,
restrict: 'E',
controller: ['$scope',function($scope){
console.log("test");
var plate = $scope.plate;
console.log(plate);
$scope.letters = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H'];
$scope.numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12];
experiments = ;
experiments[$scope.plate.experiment.well] = [$scope.plate.experiment];
}],
templateUrl: '/crims/thermofluor/experiments/table_plate.html',
scope: {
plate: '='
}
};
return directive;
function link(scope, element) {
return;
}
}

the scope that you are printing is an AngularJS Promise. You can resolve it with
scope.plate.then(function(res){ console.log(res) })– Aleksey Solovey
