AngularJS: promise in a loop

I am unable to do the promise looping. I make a service call to get list of providers, then for each provider, I make another service call to get a customer. A provider has 1 or more customers. So eventual list of customer is to be decorated and displayed. In other format I am trying to achieve: *serviceA.getProvider(){ –foreah(providers){ —foreach(provider.customerID){ —-serviceB.getCustomer(customerId) —} –} } .then( –foreach(Customer){ —updateTheCustomer; —addUpdatedCustomerToAList –} displayUpdatedCustomreList(); )* I have written following […]

Automating promises in a service

I have some very inefficient code in a service that I would like to streamline. var dayPromise = DayResource.query({ start: dateQueryParam, end: dateQueryParam }).$promise.then(function(response) { if (response.length) { response = response[0]; MealLogResource.query({ … }, function(mealLog) { mealLogDeferred.resolve(mealLog); }); … … … } var dayBack1Promise = DayResource.query({ start: dateQueryParamBack1, end: dateQueryParamBack1 }).$promise.then(function(response) { if (response.length) { response = response[0]; MealLogResource.query({ … }, function(mealLog) { mealLogDeferredBack1.resolve(mealLog); }); } else { // Instantiating new empty day response = […]

Showing dynamic content inside ngRepeat

Struggling to show dynamic content inside a ngRepeat. When it comes time to show my promise content, I’m getting an empty object {}: <div ng-controller=”DemoCtrl”> <div class=”sidebar” ng-repeat=”row in rows”> <div class=”row”> <input type=”checkbox”> <div class=”name”>{{}}</div> <div class=”title”>{{map[$index]}}</div> </div> </div> </div> and the controller: function DemoCtrl($scope, $http, $q) { const rows = function() { const rows = []; for (let i = 0; i < 12; i++) { rows.push({ id: `demo-${i}`, name: `Demo ${i}` }); […]

Angularjs ngresource getting peoblems for promise and resolve

Why does a failed assertion trigger a promise catch?

While writing unit tests for an angular app I was experiencing unexpected results. I was able to condense the unexpected behavior into a sample test. The should.equal(true, false, ‘should then’) assertion failure in the then block seems to trigger the catch block of the promise. describe.only(‘test’, function () { var $q, $rootScope; beforeEach(function () { inject(function(_$q_, _$rootScope_) { $q = _$q_; $rootScope = _$rootScope_.$new(); }); }); var stubService = sinon.stub(service, ‘getPanel’); it(‘shall…’, function() { //1 […]

loop until promise function give result

I’m looking to loop on a promise function until I have the result I want. As of now I’m using recursivity like this: function pull() { dataFactory.pullFunction().then(function(res) { pull() }) } But that’s giving me some front-end/style bugs for my loading bar for example. I would do something like this: function pull() { while (res.status == ‘ONGOING’) { dataFactory.pullFunction().then(function(res) { // my stuffs }) } } But when I try it the pullFunction() is never […]
