Question

What is the process of invoking a service from a controller?

In my MovieSearchCtrl controller class, I have a method called returnMovies(query) that looks like this:

returnMovies(query): any {
    return MovieSeat.MovieSearchService.getMovies(query);
}

Within the MovieSearchService service class, there is a function named getMovies(query) defined as:

getMovies(query) {
    let baseURL = "http://api.themoviedb.org/3/";
    return this.$resource(baseURL + "search/movie?api_key=a8f7039633f2065942cd8a28d7cadad4&query=" + query + "&callback=angular.callbacks._0");
}

In order to utilize the data returned by the getMovies() function within the MovieSearchCtrl constructor, I want to assign it to this.results. How can I achieve this?

Answer №1

To easily access movie search functionality within MovieSearchCtrl, simply inject MovieSearchService and proceed to invoke the getMovies() method as shown below:

.controller('MovieSearchCtrl ',function(MovieSearchService, $scope){
      $scope.movies =[];
      $scope.search={}; //ng-model for your input

      MovieSearchService.getMovies($scope.search.query).then(function(res){
      $scope.movies = res.data;
    });
  });

.factory('MoviesAPI', function($resource, apiHost) {
  return $resource(apiHost + '/movies/:Id'); 
});

In order to utilize the service within the controller, you must inject it.

.controller('filmController', function($routeParams, MoviesAPI) {
        var vm = this;

        vm.moviesList = [];
        var movieResource = MoviesAPI.query();

        vm.getMoviesList = function (){
              movieResource.$promise
                .then(function(response) {
                 vm.moviesList = response;
                }, function(error) {
                    // Handle errors here
                });
              };
        };

    });

Just a couple of simple steps to follow.

If the code is located in a different module, ensure it is listed as a dependency in your module definition
```
angular.module('MovieSearchCtrl', ['MovieSearchService']);
```

Next, remember to inject it into your controller definition

MovieSearchCtrl(MovieSearchService){
   this.movies = MovieSearchService.getMovies():
}
angular.controller('MovieSearchCtrl', MovieSearchCtrl);
