How to set a timer with a Vue.js class

im just using Vue.js to updates posts on a site im messing around with, this is what ive got so far (im still learning javascript, and not too great at it)
[app.js]
var Vue = require('vue');
Vue.use(require('vue-resource'));
var app = new Vue({
el: '#app',
components: {
'postlist' : require('./components/postlist/postlist.js')
}
});
[postlist.js]
module.exports = {
template: require('./postlist.template.html'),
data: function () {
return {
'search': '',
'posts' : {}
}
},
methods: {
'updatePosts' : function()
{
this.$http.get('api/posts', function(responce, status, request)
{
this.$set('posts', responce.data);
});
}
}
};
What I'm looking for is to have updatePosts fire off every x seconds, how do I do this?
ive tried doing this in the app.js
setInterval(function()
{
app.components.postlist.methods.updatePosts(); // doesnt work
app.postlist.updatePosts(); //doesnt work either
}, 500);
and tried putting the setInterval into the component itself
im pretty lost with this, whats the best way to achieve this?
updatePosts running every x seconds?

I have also trouble with scopes in Vue.
this should work
module.exports = {
template: require('./postlist.template.html'),
data: function () {
return {
'search': '',
posts: {}
}
},
methods: {
updatePosts: function () {
var self = this;
self.$http.get('api/posts', function(responce, status, request) {
self.posts = responce.data;
setTimeout(function(){ self.updatePosts() }, 2000);
});
}
},
created: function () {
this.updatePosts();
}
}
Functions in Vue works kinda different way, because your method updatePosts is not regular function. It is function defined in $vm.methods object. so It can't be called regularly like setTimeout($vm.updatePosts). Actually $vm.updatePosts doesn't exists. if you called it like $vm.updatePosts() it is different story. $vm instance automatically calls its method... So correct way is setTimeout(function(){ self.updatePosts() },2000)

You could start the request cycle in created or somewhere else in the lifecycle. It's also probably better to use recursion here so you can wait for the response to come back before you send off another one. I didn't test this code fully but it should work.
module.exports = {
template: require('./postlist.template.html'),
data: function () {
return {
'search': '',
posts: {}
}
},
methods: {
updatePosts: function () {
this.$http.get('api/posts', function(responce, status, request) {
this.posts = responce.data;
setTimeout(this.updatePosts, 2000);
});
}
},
created: function () {
this.updatePosts();
}
}

Constants not available for jest tests in Actions

When I run navAction-test.js below I get following error: TypeError: Cannot read property 'DATA_LOADED' of undefined
As I understand it the constant.DATA_LOADED is undefined, I'm guessing jest is mocking it and for this reason constant is undefined, I've tried everything I could find on the next but it remains undefined.
Is there anyone out there who can help. I would really appreciate it.
navAction.js:
var dispatcher = require('../dispatcher/AppDispatcher');
var constants = require('../constants/constants');
module.exports = {
load: function() {
def = $.ajax({
url: 'http://api.facebook.com/',
data: {},
success: function (data, textStatus, jqXHR) {
dispatcher.dispatch({type: constants.DATA_LOADED, data: data});
}
});
}
}
navAction-test.js:
jest.dontMock('../navAction.js');
describe('Tests NavigationCollectionActionCreators', function() {
var $;
var dispatcher;
var navAction;
beforeEach(function() {
$ = require('jquery');
dispatcher = require('../../dispatcher/AppDispatcher');
navAction = require('../navAction.js');
});
it('tests calls $.ajax & dispatcher ', function () {
navAction.load();
$.ajax.mock.calls[0][0].success({body: {header: {items: [{name: 'The name', link: 'http://www.facebook.com'}]}}});
expect(dispatcher.dispatch).toBeCalledWith({type: 'DATA_LOADED', data: [{name: 'The name', link: 'http://www.timeout.com'}]});
});
});
//constants.js
var keyMirror = require('keymirror');
module.exports = keyMirror({
DATA_LOADED: null,
});
UPDATE:
I got this to work by adding the following to navAction-test.js:
var constants = {
DATA_LOADED: 'DATA_LOADED',
DATA_NOT_LOADED: 'DATA_NOT_LOADED'
};
jest.setMock('../../constants/constants', constants);
Is this the correct way of doing it?

Add to test:
jest.dontMock('../constants/constants');
If you do not want to use automocking at all, you can remove all of the jest.dontMock and put instead:
jest.autoMockOff();
Your method to solve the problem (in the update at the bottom) is not appropriate in my opinion because it violates DRY (do not repeat yourself). What happens when you added another action constant? Now you have to remember to add it in the test too. That is problematic.

Reading data from $resource.get() in AngularJS

JSON/XML from REST
{
litm: "T00000245",
lotn: "00004"
}
<jdeSerials>
<litm>T00000245</litm>
<lotn>00004</lotn>
</jdeSerials>
AngularJS controller
//Searching a product with serial number/LOTN
$scope.searchProduct = function () {
var lotn = $scope.jdeSerials.lotn;
console.log("searchProduct---->" + lotn);//log-->searchProduct---->00004
$scope.JdeSerials = lotnService.get({id: lotn}, function() {
console.log($scope.jdeSerials);//log-->[object Object]
console.log($scope.jdeSerials.litm);//log-->undefined!!!!!
});
//var litm = $scope.jdeSerials.litm;
//$scope.jdeproduct = productService.get({id: litm});
};
AngularJS service
angular.module('lotnService', ['ngResource'])
.factory('lotnService', ['$resource',
function ($resource) {
console.log('------lotmService-----');
return $resource(
'http://localhost:8080/RMAServer/webresources/com.pako.entity.jdeserials/:id',
{},
{
update: { method: 'PUT', params: {id: '#lotn'} }
});
}]);
Question
How can I get a value to $scope.jdeSerials.litm? Is there any better idea to solve this like creating a service which handles this two GETs? I think that reason is the GET method is asynchronous, but what is the best solution to handle situations like this?
EDIT/update
I changed the service call like this:
$scope.JdeSerials = lotnService.get({id:lotn})
.$promise.then(function(jdeSerials) {
$scope.jdeSerials = jdeSerials;
console.log("1--------------->LITM:"+$scope.jdeSerials.litm);
});
I got the LITM, BUT I got the errormessage as well:
TypeError: Cannot read property 'then' of undefined

Try to create a get method in your resource.
angular.module('lotnService', ['ngResource'])
.factory('lotnService', ['$resource', function ($resource) {
return $resource( 'http://localhost:8080/RMAServer/webresources/com.pako.entity.jdeserials/:id',
{},
{
get: { method: 'GET', params: {id: '#lotn'}},
update: { method: 'PUT', params: {id: '#lotn'} }
});
}]);
Then in your controller, call method get from service:
lotnService.get({id:lotn}).$promise.then(
function(jdeSerials) {
$scope.jdeSerials = jdeSerials;
console.log("1--------------->LITM:"+$scope.jdeSerials.litm);
});

What angular js version are you using?
Does the following work ?
lotnService.get({id:lotn}).then(
function(jdeSerials) { ... }
);
(without the $promise)
I was browsing the docs and also angular-resource.js source for previous versions and it appears that the synthax has changed somewhere along the line.
On angular-resource.js 1.2.0 source:
The Resource instances and collection have these additional properties:
$promise: the {#link ng.$q promise} of the
original server interaction that created this * instance or
collection.
On 1.0.8 there is no mention of the $promise propery, however.

AngularJS tutorial Thinkster.io chapter 7

UPDATE: The tutorial was updated and the following question really no longer applies
Learning about AngularJS from the site thinkster.io (free ebook). But at the moment i'm stuck at chapter 7 - Creating your own user data using firebase. This is an tutorial about angularjs that works with firebase.
I have wrote all the code according to the site, but i'm getting these console errors when I want to register a user. It will create the user (in firebase -simplelogin), but not the user object (in firebase - data).:
TypeError: undefined is not a function
at Object.User.create (http://localhost:9000/scripts/services/user.js:46:19)
at http://localhost:9000/scripts/controllers/auth.js:32:22
etc.
This is the code (same as the site), the error is in the create() function and talks about the users.$save() function, snippet of User.create():
users.$save(username).then(function () {
setCurrentUser(username);
});
Complete code of user.js:
news.factory("User", function ($firebase, FIREBASE_URL, $rootScope, $log) {
var reference, users, User;
reference = new Firebase(FIREBASE_URL + "users");
users = $firebase(reference);
function setCurrentUser(username) {
$rootScope.currentUser = User.findByUsername(username);
}
$rootScope.$on("$firebaseSimpleLogin:login", function (event, authUser) {
var query = $firebase(reference.startAt(authUser.uid).endAt(authUser.uid));
query.$on("loaded", function () {
setCurrentUser(query.$getIndex()[0]);
});
});
$rootScope.$on("$firebaseSimpleLogin:logout", function () {
delete $rootScope.currentUser;
});
User = {
create: function (authUser, username) {
users[username] = {
md5_hash: authUser.md5_hash,
username: username,
"$priority": authUser.uid
};
$log.debug(users);
users.$save(username).then(function () {
setCurrentUser(username);
});
},
findByUsername: function (username) {
if (username) {
return users.$child(username);
}
},
getCurrent: function () {
return $rootScope.currentUser;
},
signedIn: function () {
return $rootScope.currentUser !== undefined;
}
};
return User;
});
Edit 1:
Registering a user now works, got it working (saving in firebase, simple login and data):
users = $firebase(reference).$asObject();
Notice the users.save() function:
create: function (authUser, username) {
users[username] = {
md5_hash: authUser.md5_hash,
username: username,
$priority: authUser.uid
};
$log.debug(users);
users.$save().then(function () {
setCurrentUser(users);
});
},
findByUsername: function (users) {
if (users) {
return users;
}
},
Edit 2:
Now I get an error at the log in of the user (see below), when I want to log in, I get an error on this this function, query.$on():
TypeError: undefined is not a function
at http://localhost:9000/scripts/services/user.js:26:19
$rootScope.$on("$firebaseSimpleLogin:login", function (event, authUser) {
var query = $firebase(reference.startAt(authUser.uid).endAt(authUser.uid));
query.$on("loaded", function () {
setCurrentUser(query.$getIndex()[0]);
});
});
What is wrong now?

This is an answer on edit 2: I have used firebase(ref), query.$loaded and searched for the right object, that's it. Maybe someone have an different answer, please post them :).
I have finally completed chapter 07!
In general (solution for Edit 2):
$rootScope.$on("$firebaseSimpleLogin:login", function (event, authUser) {
var query = $firebase(reference).$asObject();
query.$loaded(function (result) {
angular.forEach(result, function (key) {
if (key.md5_hash === authUser.md5_hash) {
setCurrentUser(key);
}
});
});
});
This is not the ideal solution, but the free ebook (atm of writing) is far from ideal. Then again, these kind of situations helps you to understand a little bit more about the firebase api and how it works with angular. But can be frustrated at times, when you just want to go through the tutorial ;).
Note! I have saved the User object and pass the User object to the findUsername() and setCurrentUser() functions instead of just the user.username.
You can also use the native array function, like some().

I think your system uses the newer version of Angularfire (version>= 0.8). Which means for running through loops that are arrays ...you need to attach .$asArray() at the end of the user definition field. Check the updates of Firebase.

displaying Data from multiple tables with AngularJs

I have been reading different posts with similar questions but I cannot get this figured out. I have a Job class that is linked to different tables such as Customer and Employee. The Data is coming back from the Database but I cannot get the Angular Table to display the linked classes. The suggestions have been to use different mods, restangular, angular-activerecord, ModelCore and this method
angular js model relationships
I am not sure the best route to take and what would be the simplest way of doing it.
app.factory('Job', function ($resource) {
return $resource('/api/apiJob/:id',
{ id: '#id' },
{ 'save': { method: 'POST' } },
{ 'update': { method: 'PUT' } },
{ 'query': { method: 'GET', isArray: false } });
});
app.factory('jobFactory', function ($http) {
return {
updateJob: function (job) {
return $http.put('/api/apiJob/' + job.JobId, job);
}
};
});
app.factory('Customer', function ($resource) {
return $resource('/api/apiCustomer/:id',
{ id: '#id' },
{ 'save': { method: 'POST' } },
{ 'update': { method: 'PUT' } },
{ 'query': { method: 'GET', isArray: false } });
});
app.factory('customerFactory', function ($http) {
return {
updateCustomer: function (customer) {
return $http.put('/api/apiCustomer/' + customer.CustomerId, customer);
}
};
});
'use strict';
app.controller('JobCtrl', function ($scope, Job, $resource, $route, jobFactory, notificationFactory, $http) {
////GET Jobs
$scope.jobArray = Job.query()
//New Job Modal
$scope.NewJobModal = function () {
$('#NewJobModal').modal();
}
$scope.submitJob = function () {
var data = {
JobId: $scope.JobId,
JobNumber: $scope.JobNumber,
JobName: $scope.JobName,
CustomerName: $scope.CustomerName,
JobDescription: $scope.JobDescription,
OriginalContract: $scope.OriginalContract,
BillingDate: $scope.BillingDate,
}
$http.post('/api/apiJob/PostNewJob', data).success(function (data, status, headers) {
console.log(data);
});
window.top.location.reload();
};
//End New Job Post
//Delete Job
$scope.deleteJob = function (job) {
Job.delete({ id: job.JobId }, function () {
if ($scope.jobArray.length === 1) {
$scope.jobArray.splice(-1, 2);
} else {
$scope.jobArray.splice(job.JobId - 1, 2);
}
window.top.location.reload();
});
};
//End Delete Job
$scope.updateJob = function (job) {
jobFactory.updateJob(job).success(successCallback).error(errorCallback);
};
$scope.job = [];
var successCallback = function (data, status, headers, config) {
notificationFactory.success();
return $('#editJobModal').modal('hide');
};
var errorCallback = function (data, status, headers, config) {
notificationFactory.error(data.ExceptionMessage);
};
//End Edit Job
}); //End Job Controller

First of all, this is a work in progress. Your code is very large and to solve this I removed a lot o noise from your plunkr, I left there only what's essential to make it work and only the code involved in it.
Working Demo
First thing to notice, on your JobController you are doing:
////GET Jobs
$scope.jobArray = Job.query();
This worked on previous versions of angular, on the current version there is no automatic promise unwrapping anymore, so you must use the then function:
////GET Jobs
Job.query().then(function(retrievedData){
$scope.jobArray = retrievedData;
});
Notice that on the plunkr I "mocked" the returning of data using $q and a timeout, I actually cleaned the json leaving only the properties that are used on the table, just to make it simpler, you don't need to do that on your code ok? Just keep that part as it is.
Maybe you'll have to modify it just to resolve the promise with the returned data, but this is up to you, the important thing is to return a promise from your query() method and resolve it.
On the HTML I noticed that you are binding the customer name like this:
<td>{{job.Customers.CustomerName}}</td>
But on your Json, the Customers property is an array of customers, so you either return one customer from your api or bind it like this:
<td>{{job.Customers[0].CustomerName}}</td>
I also noticed that there are a lot of jQuery references on your controllers like this:
$('#editJobModal').modal();
This is not recommended and I don't think it will work at all, when dealing with the DOM, always use directives and comunicate with them using bindings, thats the angular way.
Well after all this, my plunkr is showing the table with the 2 fake customers from the Json. Now I suggest you to study that code and apply those principles to your app.
I hope I could help or at least point you at the right direction.
