Angular seavice getAll is not a function - angularjs

I've got a function in an Angular controller like so:
(function () {
'use strict';
var controlledID = 'Clause.Clause';
angular.module('docapp').controller(controlledID, ['$scope', 'common', 'taskSvc', 'clauseSvc', Clauses]);
function Clauses($scope, clauseSvc, taskSvc, common) {
$scope.GetContractMaster = function GetContractMaster() {
clauseSvc.getAll()
.then(function (response) {
$scope.ContractMaster.rowData = response.d.results;
console.log(response.d.results);
});
};
$scope.GetContractMaster();
};
}
})();
My Services
(function () {
'use strict';
var app = angular.module('docapp');
app.factory("clauseSvc", ["baseSvc", function (baseService) {
var listEndPoint = '/_api/web/lists/';
var getAll = function () {
var query = listEndPoint + "GetByTitle('CLAUSE_MST')/Items?$select=Title,Title,Desc,nodes/ID&$expand=nodes";
return baseService.getRequest(query);
};
return {
getAll: getAll
};
}]);
})();
baseService
"use strict";
(function () {
angular.module("docapp")
.factory("baseSvc", ["$http", "$q", function ($http, $q) {
var baseUrl = _spPageContextInfo.siteAbsoluteUrl;
var getRequest = function (query) {
var deferred = $q.defer();
$http({
url: baseUrl + query,
method: "GET",
headers: {
"accept": "application/json;odata=verbose",
"content-Type": "application/json;odata=verbose"
}
})
.success(function (result) {
deferred.resolve(result);
})
.error(function (result, status) {
deferred.reject(status);
});
return deferred.promise;
};
return {
getRequest: getRequest
};
}]);
})();
Getting error
[true] [SYSERR] clauseSvc.getAll is not a function Object {exception:
TypeError: clauseSvc.getAll is not a function
at n.GetContractMaster
Need help

Your controller is declared as
.controller('$scope', 'common', 'taskSvc', 'clauseSvc', Clauses]);
and the function is declared as
function Clauses($scope, clauseSvc, taskSvc, common)
So, the variable clauseSvcis in fact the common service instance, and the variable common is in fact the clauseSvc service instance.
Do yourself a favor: avoid that kind of bugs and make your code easier to write and read by just avoiding this array syntax, and using ngAnnotate to make your code minifiable.

I get a Promise instead of a collection therefore error -> [filter:notarray] Expected array but received: {}:

I have this factory:
(function () {
angular.module('appContacts')
.factory('dataService', ['$q', '$http', dataService]);
function dataService($q, $http) {
return {
getAllOrganizations: getAllOrganizations,
getAllContacts: getAllContacts,
};
function getAllContacts() {
return $http({
method: 'GET',
url: 'api/allcontacts'
})
}
function getAllOrganizations() {
return $http({
method: 'GET',
url: 'api/organizations'
})
}
}
})();
And I have this Controller:
(function () {
"use strict";
angular.module('appContacts')
.controller('contactsController', function contactsController($http, dataService) {
var vm = this;
vm.organizations = [];
vm.allcontacts = [];
vm.organizations = dataService.getAllOrganizations();
vm.allcontacts = dataService.getAllContacts();
});
})();
If I make a console.log in the controller like
console.log(dataService.getAllOrganizations()) and console.log(dataService.getAllContacts()) I see I have a PROMISE therefore I get an error like
[filter:notarray] Expected array but received: {}:
How could I convert this promise in a real error that I could assign to the variables like:
vm.organizations = dataService.getAllOrganizations()
and
vm.allcontacts = dataService.getAllContacts();
?
Your services return with promise. So, you need to resolve the promise using then syntax in the controller in order to get the data from your server. You need something like this:
dataService.getAllOrganizations().then(function(result){
vm.organizations = result;
}, function(error){
console.log(error);
});
In order to having your calls by default you need a method, let's call it activate(). I'm not sure the syntax is correct, I wrote it top of my head.
Please check John Papa's style guide here.
(function () {
"use strict";
angular.module('appContacts')
.controller('contactsController', function contactsController($http, dataService) {
var vm = this;
vm.organizations = [];
vm.allcontacts = [];
var activate = function activate() {
dataService.getAllOrganizations().then(function(result){
vm.organizations = result;
}, function (error){});
dataService.getAllContacts().then(function(result){
vm.allcontacts = result;
}, function (error){});
}
activate();
});
})();

Testing factory toBeDefined error

Just started jasmine karma.
the test is failing due to following errors:
PhantomJS 2.1.1 (Mac OS X 0.0.0) dataservice spec should have dataservice be defined FAILED
Error: Timeout - Async callback was not invoked within timeout specified by jasmine.DEFAULT_TIMEOUT_INTERVAL.
Error: [$injector:unpr] Unknown provider: dataserviceProvider <- dataservice
i have provided all dependencies namely $http and $q still getting unknown provider error.
the factory has been described inside app.core module, which i have
included into the karma conf file
What am i missing.
the factory works fine inthe project
unit testing the following http factory
(function() {
'use strict';
angular
.module('app.core', [])
.factory('dataservice', dataservice);
dataservice.$inject = ['$http', '$q'];
function dataservice($http, $q) {
return {
makeRequest: makeRequest,
};
function makeRequest(params) {
var defer = $q.defer();
if (params.method == "GET") {
$http({
method: params.method,
url: params.url,
headers: params.headers
})
.then(function(response) {
defer.resolve(response);
},
function(response) {
defer.reject(response);
})
}
if (params.method == "POST") {
$http({
method: params.method,
url: params.url,
data: params.parameters,
headers: params.headers
})
.then(function(response) {
console.log(response);
defer.resolve(response);
},
function(response) {
console.log("error");
defer.reject(response);
})
}
return defer.promise;
})();
test spec:
(function(){
'use strict'
describe('dataservice spec',function(){
var dataservice;
beforeEach(function($injector){
angular.module('app.core');
//dataservice=$injector.get('dataservice')
});
beforeEach(inject(function (_dataservice_,_$http_,_$q_) {
dataservice = _dataservice_;
$http=_$http_;
$q=_$q_;
}));
// beforeEach(inject(function() {
// var $injector = angular.injector(['app.core']);
// dataservice = $injector.get('dataservice');
// }));
it('should have dataservice be defined', function () {
expect(dataservice).toBeDefined();
});
})
})();
You'll need to update your scripts as follows:
(function () {
'use strict';
angular
.module('app.core', [])
.factory('dataservice', dataservice);
dataservice.$inject = ['$http', '$q'];
function dataservice($http, $q) {
return {
makeRequest: makeRequest
};
function makeRequest(params) {
var defer = $q.defer();
if (params.method == "GET") {
$http({
method: params.method,
url: params.url,
headers: params.headers
})
.then(function (response) {
defer.resolve(response);
},
function (response) {
defer.reject(response);
})
}
if (params.method == "POST") {
$http({
method: params.method,
url: params.url,
data: params.parameters,
headers: params.headers
})
.then(function (response) {
console.log(response);
defer.resolve(response);
},
function (response) {
console.log("error");
defer.reject(response);
})
}
return defer.promise;
}
}
})();
The Unit test:
(function () {
'use strict'
describe('dataservice spec', function () {
var dataservice,
$http,
$q;
beforeEach(module('app.core'));
beforeEach(inject(function (_dataservice_, _$http_, _$q_) {
dataservice = _dataservice_;
$http = _$http_;
$q = _$q_;
}));
it('should have dataservice be defined', function () {
expect(dataservice).toBeDefined();
});
})
})();
Just make sure you're loading your module properly: beforeEach(module('app.core'));

How to set a variable from an $http call then use it in the rest of the application WITHOUT making the whole application asynchronous

I have this data
{
"config": {
"RESTAPIURL": "http://myserver/myrestsite"
}
}
and I have this factory that reads that data
'use strict';
angular.module('myApp').factory('api',
["$http", "$q",
function ($http, $q) {
function _getConfiguration() {
var deferred = $q.defer();
$http.get('/scripts/constants/config.json')
.success(function (data) {
deferred.resolve(data);
})
.error(function (data, status) {
deferred.reject(data, status);
});
return deferred.promise;
}
function _restApiUrl() {
// this doesn't work either. _getConfiguration() doesn't resolve here.
return _getConfiguration().RESTAPIURL + '/api/';
}
return {
URL: _restApiUrl
}
}
]
);
Then to use it
'use strict';
angular.module('myApp').factory('AuthService', function ($http, $q, api,NotificationService) {
function _get(creds) {
var deferred = $q.defer();
$http({method: 'GET', url: api.URL() + api.AUTH, headers: {
'Authorization': 'Basic '+creds}
})
.success(function (data, status, results, headers) {
deferred.resolve(results);
})
.error(function (data, status) {
NotificationService.redirect(status);
deferred.reject(data, status);
});
return deferred.promise;
}
return {
get:_get
};
});
So when I'm using it I am doing api.URL() and it's not working.
It used to be hard coded URL so to call it used to be api.URL. I really don't want to go through the whole app and convert everything to api.URL().then(...). That would suck.
So how can I nail down this value as a "property" instead of an asynchronous promise that has to be called over and over?
Call it once, fine. Get the value. Put it somewhere. Use the value. Don't ever call the $http again after that.
EDIT
This is turning up to be one of the most successful questions I've ever asked, and I am gratefully going through each answer in turn. Thank each one of you.
Adding a bit to what #ThinkingMedia was saying in the comment, with ui-router when defining controllers you can add a resolve parameter.
In it you can specify some promises that have to resolve before the controller is instantiated, thus you are always sure that the config object is available to the controller or other services that the controller is using.
You can also have parent/child controllers in ui-router so you could have a RootController that resolves the config object and all other controllers inheriting from RootController
.state('root', {
abstract: true,
template: '<ui-view></ui-view>',
controller: 'RootController',
resolve:{
config: ['api', function(api){
return api.initialize();
}
}
});
and your api factory:
angular.module('myApp').factory('api',
["$http", "$q",
function ($http, $q) {
var _configObject = null;
function initialize() {
return $http.get('/scripts/constants/config.json')
.then(function (data) {
_configObject = data;
return data;
});
}
// you can call this in other services to get the config object. No need to initialize again
function getConfig() {
return _configObject;
}
return {
initialize: initialize,
getConfig: getConfig
}
}
]
);
I would pass a callback to the getURL method, and save the URL when it returns. Then I would attach any subsequent requests to that callback. Here I am assuming that you are doing something similar with api.AUTH that you don't have a reference to in your code.
Pass a callback to the getURL method in the api service.
angular.module('myApp').factory('api', ["$http", "$q",
function ($http, $q) {
function _getConfiguration() {
var deferred = $q.defer();
$http.get('/scripts/constants/config.json')
.success(function (data) {
deferred.resolve(data);
})
.error(function (data, status) {
deferred.reject(data, status);
});
return deferred.promise;
}
return {
getURL: function (cb) {
var that = this;
if (that.URL) {
return cb(that.URL);
}
_.getConfiguration().then(function (data) {
that.URL = data.config.RESTAPIURL + "/api";
cb(that.URL);
});
}
}
}]);
And in your AuthService, wrap your _get inside a callback like this:
angular.module('myApp').factory('AuthService', function ($http, $q, api, NotificationService) {
function _get(creds) {
var deferred = $q.defer();
var getCallback = function (url) {
$http({
method: 'GET',
url: url + api.AUTH,
headers: {
'Authorization': 'Basic ' + creds
}
})
.success(function (data, status, results, headers) {
deferred.resolve(results);
})
.error(function (data, status) {
NotificationService.redirect(status);
deferred.reject(data, status);
});
};
api.getURL(getCallback);
return deferred.promise;
}
return {
get: _get
};
});
Why don't you initialize the factory when the app is loading and put the variable onto another property? Something like this:
angular.module('myApp').factory('api', ["$http", "$q",
function ($http, $q) {
// store URL in a variable within the factory
var _URL;
function _initFactory() {
var deferred = $q.defer();
$http.get('/scripts/constants/config.json')
.success(function (data) {
// Set your variable after the data is received
_URL = data.RESTAPIURL;
deferred.resolve(data);
});
return deferred.promise;
}
function getURL() {
return _URL;
}
return {
initFactory: _initFactory,
URL: getURL
}
}
]
);
// While the app is initializing a main controller, or w/e you may do, run initFactory
//...
api.initFactory().then(
// may not need to do this if the URL isn't used during other initialization
)
//...
// then to use the variable later
function _get(creds) {
var deferred = $q.defer();
$http({method: 'GET', url: api.URL + api.AUTH, headers: {
'Authorization': 'Basic '+creds}
})
.success(function (data, status, results, headers) {
deferred.resolve(results);
})
return deferred.promise;
}
I see you haven't used any $resource's here, but I'm hoping you have a good understanding of them:
in factories/delay-resource.js:
'use strict'
angular.module('myApp').factory('delayResource', ['$resource', '$q',
function($resource, $q){
var _methods = ['query', 'get', 'delete', 'remove', 'save'];
var shallowClearAndCopy = function(src, dst) {
dst = dst || {};
angular.forEach(dst, function(value, key){
delete dst[key];
});
for (var key in src) {
if (src.hasOwnProperty(key) && !(key.charAt(0) === '$' && key.charAt(1) === '$')) {
dst[key] = src[key];
}
}
return dst;
}
var delayResourceFactory = function(baseUrlPromise, url, paramDefaults){
var _baseUrlPromise = baseUrlPromise,
_url = url,
_paramDefaults = paramDefaults;
var DelayResource = function(value){
shallowClearAndCopy(value || {}, this);
};
_methods.forEach(function(method){
DelayResource[method] = function(params, successCB, errCB, progressCB){
if (angular.isFunction(params)) {
progressCB = successCB;
errCB = errHandlers;
successCB = params;
errHandlers = params = null;
}
else if (!params || angular.isFunction(params)){
progressCB = errCB;
errCB = successCB;
successCB = errHandlers;
params = {};
}
var _makeResultResource = function(url){
var promise = $resource(url, _paramDefaults)[method](params);
(promise.$promise || promise).then(
function successHandler(){
var data = arguments[0];
if (isInstance){
if (angular.isArray(data))
for (var i = 0; i < data.length; i++)
data[i] = new DelayResource(data[i])
else if (angular.isObject(data))
data = new DelayResource(data)
}
successCB.apply(successCB, arguments)
resultDelay.resolve.apply(resultDelay.resolve, arguments)
},
function(err){
errCB.apply(errCB, arguments)
resultDelay.reject.apply(resultDelay.reject, args)
},
function(){
progressCB.apply(progressCB, arguments)
resultDelay.notify.apply(resultDelay.notify, arguments)
}
)
}
var isInstance = this instanceof DelayResource,
resultDelay = $q.defer();
if (!angular.isString(_baseUrlPromise) && angular.isFunction(_baseUrlPromise.then))
_baseUrlPromise.then(
function successCb(apiObj){
_makeResultResource(apiObj.RESTAPIURL + _url)
},
function successCb(){
throw 'ERROR - ' + JSON.stringify(arguments, null, 4)
})
else
_makeResultResource(_baseUrlPromise.RESTAPIURL + _url);
return resultDelay.promise;
};
DelayResource.prototype['$' + method] = function(){
var value = DelayResource[method].apply(DelayResource[method], arguments);
return value.$promise || value;
}
});
return DelayResource;
}
return delayResourceFactory;
}]);
This will be the base factory that all requests to that REST API server will go through.
Then we need a factories/api-resource.js:
angular.module('myApp').factory('apiResource', ['delayResource', 'api', function (delayResource, api) {
return function (url, params) {
return delayResource(api.URL(), url, params);
};
}])
Now all factories created will just have to call the apiResource to get a handle on a resource that will communicate with the REST API
Then in a file like factories/account-factory.js
angular.module('myApp').factory('AuthRoute', ['apiResource', 'api', function (apiResource, api) {
return apiResource(api.AUTH);
}]);
Now in factories/auth-service.js:
'use strict';
angular.module('myApp').factory('AuthService', ['$q', 'AuthRoute', 'NotificationService', function ($q, AuthRoute, api, NotificationService) {
function _get(creds) {
var deferred = $q.defer();
AuthRoute.get()
.then(
function successCb(results){
deferred.resolve(results);
},
function errCb(){
// cant remember what comes into this function
// but handle your error appropriately here
//NotificationService.redirect(status);
//deferred.reject(data, status);
}
);
return deferred.promise;
}
return {
get:_get
};
}]);
As you can imagine, I haven't been able to test it yet, but this is the basis. I'm going to try create a scenario that will allow me to test this. In the mean time, feel free to ask questions or point out mistakes made
Late Addition
Forgot to add this:
'use strict';
angular.module('myApp').factory('api', ["$http", "$q", function ($http, $q) {
var restApiObj,
promise;
function _getConfiguration() {
if (restApiObj)
return restApiObj;
if (promise)
return promise;
promise = $http.get('/scripts/constants/config.json')
.then(function (data) {
restApiObj = data;
promise = null;
return data;
},
function (data, status) {
restApiObj = null;
promise = null;
});
return promise;
}
return {
URL: _getConfiguration
}
}]);
Continuing with the ui-router scenario
.state('member-list', {
url: '/members?limit=&skip='
templateUrl: '/views/members/list.html',
controller: 'MemberListCtrl',
resolve:{
members: ['$stateParams', 'MembersLoader', function($stateParams,MembersLoader){
return MembersLoader({skip: $stateParams.skip || 0, limit: $stateParams.limit || 10});
}
}
});
factory
.factory('MemberRoute', ['apiResource', function(apiResource){
return apiResource('/members/:id', { id: '#id' });
}])
.factory('MembersLoader', ['MembersRoute', function(MembersRoute){
return function(params){
return MemberRoute.query(params);
};
}])
.factory('MemberFollowRoute', ['apiResource', 'api', function(apiResource, api){
return apiResource(api.FOLLOW_MEMBER, { id: '#id' });
}])
controller
.controller('MemberListCtrl', ['$scope', 'members', 'MemberRoute', 'MemberFollowRoute', function($scope, members, MemberRoute, MemberFollowRoute){
$scope.members = members;
$scope.followMember = function(memberId){
MemberFollowRoute.save(
{ id: memberId },
function successCb(){
//Handle your success, possibly with notificationService
},
function errCb(){
// error, something happened that doesn't allow you to follow memberId
//handle this, possibly with notificationService
}
)
};
$scope.unfollowMember = function(memberId){
MemberFollowRoute.delete(
{ id: memberId },
function successCb(){
//Handle your success, possibly with notificationService
},
function errCb(){
// error, something happened that doesn't allow you to unfollow memberId
//handle this, possibly with notificationService
}
)
};
}]);
With all this code above, you will never need to do any sort of initialization on app start, or in some abstract root state. If you were to destroy your API config every 5 mins, there would be no need to manually re-initialize that object and hope that something isn't busy or in need of it while you fetch the config again.
Also, if you look at MembersRoute factory, the apiResource abstracts/obscures the api.URL() that you were hoping not to have to change everywhere. So now, you just provide the url that you want to make your request to, (eg: /members/:id or api.AUTH) and never have to worry about api.URL() again :)

Angularjs Reference Error: service is not defined

I would like to inject my service file into my controller using AngularJS so I can make the $http calls, but when I do so, I receive an error that it isn't defined.
Here's my service call in a separate file that has been included into the index.html.
(function () {
'use strict';
angular.module('App')
.service('MemberService', ['$http', '$q',
function MemberService($http, $q) {
var svc = this;
svc.postMembers = _postMembers;
var deferred = $q.defer();
_postMembers.$http({
method: 'POST',
url: '/api/MemberSearch',
data: data,
headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
}).then(function (result) {
deferred.resolve(result)
}, function (error) {
deferred.reject(error);
});
return deferred.promise;
console.log("promise", deferred.promise);
}]);
})();
Now, here's the controller.js
(function () {
'use strict';
angular
.module('App')
.controller('MemberController', MemberController);
MemberController.$inject = ['$scope', '$http', '$q', 'MemberService', MemberService];
function MemberController($http, MemberService) {
var vm = this;
vm.search = {}; //a blank object to contain form data
vm.memberSearchForm = null; //reference to the actual form in html
vm.memberResult = []; //a blank object to handle returned data
vm.memberSearch = _memberSearch;
vm.showErrors = false;
function _memberSearch() {
vm.showErrors = true;
console.log("inside _memberSearch");
var promisePost = MemberService.postMembers(vm.search)
console.log("vm.search", vm.search);
}
};
})();
Any help is much appreciated.

Mocking HTTP service unit test with AngularJS and Jasmine

I am attempting to build a mock service so that my unit tests can verify certain functions are called and updated accordingly. Unfortunately I cannot get this to work.
Im currently getting an error undefined is not a function on this line:
spyOn(statusService, 'getModuleStatus').andCallThrough();
My actual service looks like this:
serviceStatusServices.factory('serviceStatusAppAPIservice', function ($http) {
var serviceStatusAppAPI = {};
serviceStatusAppAPI.getModuleStatus = function () {
return $http({
method: 'JSON',
url: '/settings/getservicestatusandconfiguration'
});
}
serviceStatusAppAPI.setModuleStatus = function (module) {
return $http({
method: 'POST',
url: '/settings/setservicestatusandconfiguration',
data: { moduleId: module.ModuleId, configData: module.ConfigValues }
});
}
return serviceStatusAppAPI;
});
My update function
serviceStatusControllers.controller('serviceStatusController', ['$scope', 'serviceStatusAppAPIservice', '$filter', '$timeout', function ($scope, serviceStatusAppAPIservice, $filter, $timeout) {
$scope.update = function () {
$scope.loading = true;
serviceStatusAppAPIservice.getModuleStatus().then(function (response) {
$scope.modules = $filter('orderBy')(response.data.moduleData, 'ModuleName')
...
My tests look like this
describe('ServiceStatusController', function () {
beforeEach(module("serviceStatusApp"));
var scope;
var statusService;
var controller;
var q;
var deferred;
// define the mock people service
beforeEach(function () {
statusService = {
getModuleStatus: function () {
deferred = q.defer();
return deferred.promise;
}
};
});
// inject the required services and instantiate the controller
beforeEach(inject(function ($rootScope, $controller, $q) {
scope = $rootScope.$new();
q = $q;
controller = $controller('serviceStatusController', {
$scope: scope, serviceStatusAppAPIservice: statusService });
}));
describe("$scope.update", function () {
it("Updates screen", function () {
spyOn(statusService, 'getModuleStatus').andCallThrough();
scope.update();
deferred.resolve();
expect(statusService.getModuleStatus).toHaveBeenCalled();
expect(scope.modules).not.toBe([]);
});
});
});
Also, how do I pass any mock data returned from the service to the caller. Currently in my model I do serviceStatusAppAPI.getModuleStatus(data) then use data.Data to get out the returned JSON.
I assume if you are doing something like this in your ctrl
scope.update = function() {
serviceStatusAppAPIservice.setModuleStatus(url).then(function (data) {
scope.modules = data;
})
};
Service which returns promise
.factory('serviceStatusAppAPI', function($http, $q) {
return {
getModuleStatus: function() {
var defer = $q.defer();
$http({method: 'GET', url: '/settings/getservicestatusandconfiguration'})
.success(function(data, status, headers, config) {
// this callback will be called asynchronously
// when the response is available
defer.resolve(data);
})
.error(function(data, status, headers, config) {
// called asynchronously if an error occurs
// or server returns response with an error status.
window.data = data;
});
return defer.promise;
}
};
});
So in you controller you will get data like this
serviceStatusAppAPI.getModuleStatus().then(function (data) {
$scope.modules = $filter('orderBy')(data.moduleData, 'ModuleName')
})
This is how you can run your unit test case
beforeEach(function() {
var statusService = {};
module('myApp', function($provide) {
$provide.value('serviceStatusAppAPIservice', statusService);
});
statusService.modalStatus = {
moduleData: [{ModuleName: 'abc'}, {ModuleName: 'def'}]
};
inject(function ($q) {
statusService.setModuleStatus = function () {
var defer = $q.defer();
defer.resolve(this.modalStatus);
return defer.promise;
};
statusService.getModuleStatus = function () {
var defer = $q.defer();
defer.resolve(this.modalStatus);
return defer.promise;
};
});
});
beforeEach(inject(function ($rootScope, $controller, _$stateParams_) {
scope = $rootScope.$new();
stateParams = _$stateParams_;
controller = $controller;
}));
var myCtrl = function() {
return controller('ServiceStatusController', {
$scope: scope,
});
};
it('should load status', function () {
myCtrl();
scope.update();
scope.$digest();
expect(scope.modules).toBe({
status: 'active'
});
});
