I have a unique service called "usersService". I want to create a special method that interacts with another custom service I built. This other service has two handy methods: getUser() and getCurrentUser(). The getCurrentUser() method relies on the injected service to fetch the User ID (UID), which is then used to execute the getUser() method. My main challenge is figuring out how to return the nested promise from the getCurrentUser() method.
Explaining this question can be a little tough, but here's the one-of-a-kind code...
svs.service("usersService", function($rootScope, $http, loginService, alertBoxService) {
var self = this;
self.getUser = function(identifier, column) {
if (typeof(column) === 'undefined') column = "uid";
return $http.get($rootScope.api + "/getUser/" + identifier + "/" + column);
}
self.getCurrentUser = function() {
var currentUserPromise;
loginService.getCurrentUid().then(
function(response) {
if (response.data === "false") {
alertBoxService.trigger($rootScope.unexpectedApiResponse);
} else {
console.log(self.getUser(response.data));
currentUserPromise = self.getUser(response.data);
}
}, function(response) {
alertBoxService.trigger($rootScope.asyncFailed);
}
);
return currentUserPromise;
}
});
