Angularjs - Provider not recognized:

I'm encountering an issue that keeps popping up:

Error: [$injector:unpr] Unknown provider: UsersServiceProvider <- UsersService

I attempted to address this problem by adding ['UsersService' before my controller function, after reading about it on https://docs.angularjs.org/error/$injector/unpr. However, the solution didn't seem to resolve the error. Here is the code snippet where I have only executed yo angular and then yo angular:service users.

This segment belongs to controllers/main.js

angular.module('pmsFrontApp')
  .controller('MainCtrl', ['UsersService',function ($scope, UsersService) {

    $scope.form = { firstName: '', lastName: '' };
    UsersService.fetchAll().then(function(data) {
    //console.log(data);
    //$scope.lista = data;
  });
}]);

Similarly, this portion can be found in services/users.js

angular.module('pmsFrontApp')
  .service('UsersService', function ($q,$http) {
    this.fetchAll = function() {
      var defer = $q.defer();
      $http.get('http://localhost:8888/users', /*{
        params: {}
      }*/).success(function(data) {
        defer.resolve(data);
      }).error(function() {
        defer.reject('No vieja');
      });

      return defer.promise;
    }

  });
});

Answer №1

To achieve the desired outcome, follow this code structure:

.controller('MainCtrl', ['$scope', 'UsersService', function ($scope, UsersService) {

Make sure to explicitly specify both $scope and your service when injecting them. Keep in mind to inject them in the exact same order within the function.

In this scenario, your $scope variable represents your UsersService.
