Promises in AngularJS with $q service :-
Yesterday we were able to create the form and save it. But we want to exit the form once we click on save button. form is actually retrieved from createModal of showCreateModal scope variable which has the template. We need to call the hide function from createModal. we will create the promise function to hide the form and for this purpose we use $q which is a support parameter to $promise.
//trimmed code
app.service('ContactService', function (Contact, $q) {
//trimmed code
//trimmed code
'createContact': function (person) {
var d = $q.defer();
self.isSaving = true;
Contact.save(person).$promise.then(function () {
self.isSaving = false;
d.resolve()
});
return d.promise;
}
//trimmed code
And in the createContact we will hide the modal.
As you could notice in the above screencast, we will make sure we clean the contact list which will not spread onto contactDetail once we save the save the form.
//trimmed code createContact service
Contact.save(person).$promise.then(function () {
self.isSaving = false;
self.selectedPerson = null;
self.hasMore = true;
self.page = 1;
self.persons = [];
self.loadContacts();
d.resolve()
});
//trimmed code
