Tips for effectively transferring information from a Service to a Controller

I have encountered an issue where the data fetched by my HTTP service is not being sent to the controller. Despite correctly retrieving the data, it seems to be getting lost in transit.

After realizing that the query is executed asynchronously, I attempted to implement $q.defer to handle this. However, even after referencing a similar question on Stack Overflow (link provided: AngularJS $http call in a Service, return resolved data, not promises), the problem persists.

This is how my Service looks:

.service("builds", ['$http', '$q', function($http, $q) {
  var deferred = $q.defer();

  $http({
      method:'GET',
      url: '/builds',
      cache : true
  }).success(function(data) {
      deferred.resolve(data);
  }).error(function(msg){
      deferred.reject(msg);
  });
  console.log(deferred.promise);
  return deferred.promise;}]);

Furthermore, here is my routeProvider setup:

$routeProvider.
    when('/builds', {
        controller: ['$scope', 'buildsData', function ($scope, buildsData) {
            console.log("In routeprovider:" + buildsData);
            $scope.allBuilds = buildsData;
        }],
      template: '<build-list></build-list>',
      resolve: {
          buildsData: ['builds', function(builds){
              return builds;
          }]
      }
    })

Lastly, let's take a look at a snippet of my Controller:

var app = angular.
 module('buildList').
  component('buildList', {
   templateUrl: 'build-list/build-list.template.html',
    controller: function BuildListController($scope, $window,$location,$cookies, builds) {
     console.log($scope.allBuilds);
     $scope.league = $scope.allBuilds;

Answer №1

According to @vishal's advice

It is recommended to create a method within the service, as services typically contain multiple get and set methods (which is considered best practice).

Create a function called fetchData

function fetchData()
{
  $http({
      method:'GET',
      url: '/data',
      cache : true
  })
}

Then, you can call this method in the controller

Within the controller, inject the service and then

data.fetchData().then(function(res){
//result

},function(err){

//error
}
);

Answer №2

Avoid making this mistake:

 controller: ['$scope', 'projectsInfo', function ($scope, projectsInfo) {
            console.log("Inside routeprovider:" + projectsInfo);
            $scope.allProjects = projectsInfo;
        }],

Furthermore, create a controller in a separate file:

You have the option to simply:

 when('/projects', {
        controller: 'ProjectListController',
        template: '<project-list></project-list>',
        resolve: {
            projectsInfo: ['projects', function(projects){
                return projects;
            }]
        }
    })

Afterwards, within your controller

$scope.allProjects = projectsInfo;

Moreover, if you wish to add additional functions to it, your service should appear like so:

.service("projects", ['$http', '$q', function($http, $q) {

      var deferred = $q.defer();

    getProjects: function(){
      $http({
          method:'GET',
          url: '/projects',
          cache : true
      }).success(function(data) {
          deferred.resolve(data);
      }).error(function(msg){
          deferred.reject(msg);
      });
      console.log(deferred.promise);
      return deferred.promise;}]);
    }
