I know this questions has almost the same title but the issue is different.
I'm using Jade template engine v.1.11.0 built into latest Keystone.js release. In a controller, I query the data with two view.on('init') callbacks. First callback only queries one record and always passes. The second sometimes don't.
category.js
var keystone = require('keystone');
var async = require('async');
exports = module.exports = function (req, res) {
var view = new keystone.View(req, res);
var locals = res.locals;
// Init locals
locals.section = 'category';
locals.filters = {
category: req.params.category
};
locals.data = {
sections: [],
category: {}
};
// Load current category
view.on('init', function (next) {
var q = keystone.list('Category').model.findOne({
key: locals.filters.category
});
q.exec(function (err, result) {
locals.data.category = result;
locals.section = locals.data.category.name.toLowerCase();
next(err);
});
});
// Load sections
view.on('init', function (next) {
var q = keystone.list('Section').model.find().where('category').in([locals.data.category]).sort('sortOrder').exec(function(err, results) {
if (err || !results.length) {
return next(err);
}
async.each(results, function(section, next) {
keystone.list('Article').model.find().where('section').in([section.id]).sort('sortOrder').exec(function(err, articles){
var s = section;
if (articles.length) {
s.articles = articles;
locals.data.sections.push(s);
} else {
locals.data.sections.push(s);
}
});
}, function(err) {
console.log(locals.data.sections);
});
next(err);
});
});
view.render('category');
};
In my view, I should always get this passed:
sections: { _id: 574b909b43ff68163ed86bf2, publicTitle: 'Title 1', key: 'name-1', sortOrder: 3, name: 'Name 1', __v: 0, category: 574b8960947f45f034ac89b4, text: '', image: {} }
category: { _id: 574b8960947f45f034ac89b4, key: 'blabla', sortOrder: 1, name: 'Blabla', __v: 0, image: {} }
But 60% of the time, I get this:
sections:
category: { _id: 574b8960947f45f034ac89b4, key: 'johndoe', sortOrder: 1, name: 'JohnDoe', __v: 0, image: {} }
Strange thing is, If I go to another category, which has more sections and like 30 articles, I get sections 90% of the time, but still missing them 10%. This persists in both development and production.
Is some "next()" firing too early? I can't see where I messed up.
Alright. After some reading on async I managed to get it to work properly using async.parallel.
var keystone = require('keystone');
var async = require('async');
exports = module.exports = function (req, res) {
var view = new keystone.View(req, res);
var locals = res.locals;
// Init locals
locals.section = 'category';
locals.filters = {
category: req.params.category
};
locals.data = {
sections: [],
category: {}
};
// Load current category
view.on('init', function (next) {
var q = keystone.list('Category').model.findOne({
key: locals.filters.category
});
q.exec(function (err, result) {
locals.data.category = result;
locals.section = locals.data.category.name.toLowerCase();
getChildrenRecords(locals.data.category, next);
});
});
function getChildrenRecords(category, next){
var q = keystone.list('Section').model.find().where('category').in([category]).sort('sortOrder').exec(function(err, results) {
if (err || !results.length) {
return next(err);
}
callItems = [];
for(var i = 0; i < results.length; i++) {
var data = results[i];
callItems.push(makeCallbackFunction(data));
}
function makeCallbackFunction(section) {
return function (callback) {
keystone.list('Article').model.find().where('section').in([section.id]).sort('sortOrder').exec(function(err, articles){
if (err) return callback(err);
if (articles.length) { section.articles = articles; }
locals.data.sections.push(section);
callback();
});
};
}
async.parallel(callItems, function(err, results){
next(err);
});
});
}
// Render the view
view.render('category');
};

I have an action where I need to update MongoDB entry including _id field, which requires deleting old entry and making a new one, here is server side:
exports.update = function(req, res, next){
var outcome = [];
outcome.previousId = req.params.id;
outcome.newId = req.body.name;
var getPreviousRecord = function(callback) {
req.app.db.models.AccountGroup
.findOne({ _id: req.params.id })
.lean()
.exec(function(err, accountGroups) {
if (err) {
return callback(err, null);
}
outcome.accountGroups = accountGroups;
return callback(null, 'done');
});
};
var makeNewRecord = function(callback) {
var permissions = outcome.accountGroups.permissions;
var fieldsToSet = {
_id: outcome.newId.toLowerCase(),
name: outcome.newId,
permissions: permissions
};
req.app.db.models.AccountGroup
.create(fieldsToSet, function(err, record) {
if (err) {
return callback(err, null);
}
outcome.record = record;
return callback(null, 'done');
});
};
var deletePreviousRecord = function() {
req.app.db.models.AccountGroup
.findByIdAndRemove(outcome.previousId)
.exec(function(err) {
if (err) {
return next(err);
}
res.redirect('admin/account-groups/' + outcome.newId + '/');
});
};
var asyncFinally = function(err) {
if (err) {
return next(err);
}
};
require('async').series([getPreviousRecord, makeNewRecord, deletePreviousRecord], asyncFinally);
};
It works fine, but I can't make this work normally on the front-end, it returns me both old route and a new route, for example:
PUT /admin/account-groups/customers22/admin/account-groups/Customers2233/ 404 213.749 ms - 31
where customers22 is old _id and customers2233 is new _id. If I navigate from another page to new entry it gets route normally.
On client side:
(function() {
'use strict';
app = app || {};
app.Details = Backbone.Model.extend({
idAttribute: '_id',
defaults: {
success: false,
errors: [],
errfor: {},
name: ''
},
url: function() {
return '/admin/account-groups/'+ app.mainView.model.id +'/';
},
parse: function(response) {
if (response.accountGroup) {
app.mainView.model.set(response.accountGroup);
delete response.accountGroup;
}
return response;
}
});
app.DetailsView = Backbone.View.extend({
el: '#details',
events: {
'click .btn-update': 'update'
},
template: Handlebars.compile( $('#tmpl-details').html() ),
initialize: function() {
this.model = new app.Details();
this.syncUp();
this.listenTo(app.mainView.model, 'change', this.syncUp);
this.listenTo(this.model, 'sync', this.render);
this.render();
},
syncUp: function() {
this.model.set({
_id: app.mainView.model.id,
name: app.mainView.model.get('name')
});
},
render: function() {
this.$el.html(this.template( this.model.attributes ));
for (var key in this.model.attributes) {
if (this.model.attributes.hasOwnProperty(key)) {
this.$el.find('[name="'+ key +'"]').val(this.model.attributes[key]);
}
}
},
update: function() {
this.model.save({
name: this.$el.find('[name="name"]').val()
});
}
});
app.MainView = Backbone.View.extend({
el: '.page .container',
initialize: function() {
app.mainView = this;
this.model = new app.AccountGroup( JSON.parse( unescape($('#data-record').html()) ) );
// ...
app.detailsView = new app.DetailsView();
}
});
$(document).ready(function() {
app.mainView = new app.MainView();
});
}());
It probably requires to trigger both model.save and model.destroy or prevent URL being used. Any advice on how to do it is appreciated, thank you.
Edit
Just a typo mistake here that is not related to the question, recklessly checking routes, see as cancelled
I believe the problem is here:
res.redirect('admin/account-groups/' + outcome.newId + '/');
That's a relative path so it'll be appended onto the current URL. I suspect you want something like this:
res.redirect('/admin/account-groups/' + outcome.newId + '/');
I have a module which I export and which has a method editHeroImage which I am trying to test using mocha, chai and sinon. The modules has two objects that are passed as arguments, connection and queries. These are mySql objects, one containing the connection to the database and the other the query strings which are defined in their separate modules. The expObj which I am exporting and trying to test is a "helper" module.
I have successfully tested other methods of this module in the same way I am trying to test this method, but, however when I run into methods which use the async module for some reason, my tests no longer behave as expected. I wonder if I am missing something in this particular case, because I have tested other modules and methods which also use async and have not come across this behaviour.
When I run the tests, it logs "HELLO!" as expected but the assertion that the callbackSpy has been called, fails.
I am losing my mind here! Please help! What is going on? Could there be contamination between test suits?
Method under test:
expObj.editHeroImage = function(connection, queries, postId, postData, callback) {
async.waterfall([
function(next) {
var qString = queries.getSinglePostById();
connection.query(qString, [postId], function(err, results) {
if (err) {
return next(err);
}
if (!results.length) {
console.log('NO POST FOUND WITH ID ' + postId);
return callback();
}
next(null, results[0].hero_image);
});
},
function(heroImageId, next) {
if (!heroImageId) {
console.log('HERO IMAGE IS NEW - NEXT TICK!');
return next();
}
// Delete resized images of hero image
var queryStr = queries.deleteResizedImages();
var resizedVals = [heroImageId];
connection.query(queryStr, resizedVals, function(err) {
if (err) {
return callback(err);
}
console.log('DELETED RESIZED IMAGES OF HERO IMAGE ' + heroImageId);
var qString = queries.updateHeroImagePath();
var values = [postData.hero_image, heroImageId];
return connection.query(qString, values, function(err, results) {
if (err) {
return next(err);
}
console.log('UPDATED HERO IMAGE ' + heroImageId + ' WITH PATH ' + postData.hero_image);
next('break');
});
});
},
function addHeroImage(next) {
var qString = queries.insertImage();
var values = [postData.hero_image, postId];
connection.query(qString, values, function(err, results) {
if (err) {
return next(err);
}
next(null, results.insertId);
});
},
function addHeroImagePathToPost(heroImageId, next) {
var qString = queries.saveHeroImageId();
var values = [heroImageId, postId];
connection.query(qString, values, function(err) {
if (err) {
return next(err);
}
next();
});
}
], function(err) {
if (err && err !== 'break') {
return callback(err);
}
console.log('HELLO!');
callback(null);
});
};

Your assertion is probably executing before your async function has returned.
There are a number of ways to ensure your async functions have finished executing. The cleanest is to format your mocha test differently.
describe('...', function () {
var callbackSpy;
before(function () {
var _post = {
id: '123',
title: 'vf',
sub_title: 'vf',
slug: 'vf',
reading_time: 4,
created_at: '123',
published_at: '123',
deleted_on: false,
hero_image: 'hero_image_path'
};
var _postId = '123';
queryStub.onCall(0).callsArgWith(2, null, [{
hero_image: '55'
}]);
queryStub.onCall(1).callsArgWith(2, null);
queryStub.onCall(2).callsArgWith(2, null);
return testedModule.editHeroImage(connectionStub, fakeQueriesObj, _postId, _post, function () {
console.log(arguments); // --> {'0': null} as expected
callbackSpy.apply(null, arguments);
});
});
it('edits hero image', function () {
expect(callbackSpy).has.been.calledWith(null);
});
});
Notice that I have wrapped your assertion in a describe block so we can use before. Your actual logic for setting up stubs and executing the class has been moved to the before block and a return added, this ensures the async function is complete before moving on to your assertions.
Your other tests may have passed, but they will also be susceptible to this and it is purely a timing issue.
Indeed #Varedis was right about it being a timing issue. However using your suggestion of wrapping the assertion in a describe bloack and using the before function to set-up the test resulted in my stubs no longer working correctly. However taking your suggestion about timing into account I managed to solve the issue by using the done callback within my test suit. By keeping the set-up I made a slight change and my tests suddenly passed:
it('edits hero image', function(done) {
var _post = {
id: '123',
title: 'vf',
sub_title: 'vf',
slug: 'vf',
reading_time: 4,
created_at: '123',
published_at: '123',
deleted_on: false,
hero_image: 'hero_image_path'
};
var _postId = '123';
queryStub.onCall(0).callsArgWith(2, null, [{hero_image: '55'}]);
queryStub.onCall(1).callsArgWith(2, null);
queryStub.onCall(2).callsArgWith(2, null);
testedModule.editHeroImage(connectionStub, fakeQueriesObj, _postId, _post, function() {
callbackSpy.apply(null, arguments);
expect(callbackSpy).has.been.calledWith(null);
expect(callbackSpy).has.not.been.calledWith('FDgdjghg');
done();
});
});
I want to wait for my functions like fetching all result first, then consoling my result.
exports.listofAllFeaturedProd = (req, res) => {
Product.find({is_featured:'1'},function(error,fetchallFeatProds)
{
var allProducts = new Array();
var pp = 0;
var products = new Array();
for (var ProductId in fetchallFeatProds)
{
var pArr = [];
pArr['_id'] = fetchallFeatProds[ProductId]._id;
pArr['name'] = fetchallFeatProds[ProductId].name;
pArr['sku'] = fetchallFeatProds[ProductId].sku;
pArr['description'] = fetchallFeatProds[ProductId].description;
pArr['price'] = fetchallFeatProds[ProductId].price;
pArr['large_image'] = fetchingImage(fetchallFeatProds[ProductId]._id);
pArr['brand'] = fetchingBrand(fetchallFeatProds[ProductId].brand_id);
console.log('#################### IMAGE ####################');
console.log(pArr);
pp++;
}
console.log(products);
});
};
function fetchingImage(pid)
{
ProductImage.findOne({product_id:pid},function(error,fetchallFeatProdsImgs)
{
console.log(fetchallFeatProdsImgs.large_image);
return fetchallFeatProdsImgs.large_image;
});
}
function fetchingBrand(bid)
{
Brand.findOne({_id:bid},function(error,fetchAllBrands)
{
console.log(fetchAllBrands);
return fetchAllBrands;
});
}
node not wait for functions and console undefined after that console my function result. how i stop my code for fetching first result then console all data in array.
Output for console.log(pArr);
[ _id: 57bd996ebf8c930b2bcc06a1,
name: 'New Product',
sku: 'New-Product',
description: 'New Product',
price: 'test',
large_image: undefined,
brand: undefined ]
After that added console inside functions which gave results as below:
Output for fetchingImage
images/12.png
Output for fetchingBrand
{ user_id: '57b42b571fc35e49162de413',
brand_name: '10 Fork ',
brand_logo: 'uploads/brands_logo/1472027911329_5.png',
brand_desc: '10 Fork',
_id: 57bd5ce6cebed2a3189cedcf,
__v: 0 }
Desired output is:
[ _id: 57bd996ebf8c930b2bcc06a1,
name: 'New Product',
sku: 'New-Product',
description: 'New Product',
price: 'test',
large_image: images/12.png,
brand: { user_id: '57b42b571fc35e49162de413',
brand_name: '10 Fork ',
brand_logo: 'uploads/brands_logo/1472027911329_5.png',
brand_desc: '10 Fork',
_id: 57bd5ce6cebed2a3189cedcf,
__v: 0 } ]
Try below code:
var temp = [],
async = require('async');
async.eachSeries(fetchallFeatProds, function(ProductId, callback)
{
pArr['_id'] = ProductId._id;
pArr['name'] = ProductId.name;
pArr['sku'] = ProductId.sku;
pArr['description'] = ProductId.description;
pArr['price'] = ProductId.price;
pArr['large_image'] = fetchingImage(ProductId._id);
pArr['brand'] = fetchingBrand(ProductId.brand_id);
temp.push(pArr);
callback(null);
}, function(err){
console.log(temp); //This should give you desired result
});
If it is not working still, try using callbackfor the functions fetchingImage and fetchingBrand. Or you may try using async.parallel as well inside eachSeries.
EDIT:-
async-eachseries
Change your functions with callback.
function fetchingImage(pid, callback)
{
ProductImage.findOne({product_id:pid},function(error,fetchallFeatProdsImgs)
{
console.log(fetchallFeatProdsImgs.large_image);
callback(error,fetchallFeatProdsImgs.large_image);
});
}
function fetchingBrand(bid, callback)
{
Brand.findOne({_id:bid},function(error,fetchAllBrands)
{
console.log(fetchAllBrands);
calback(error,fetchAllBrands);
});
}
Use async.parallel so that it will wait till both the functions are done. Then push into temp array. Doc to refer
async.eachSeries(fetchallFeatProds, function(ProductId, callback)
{
var pArr = {};
pArr['_id'] = ProductId._id;
pArr['name'] = ProductId.name;
pArr['sku'] = ProductId.sku;
pArr['description'] = ProductId.description;
pArr['price'] = ProductId.price;
async.parallel([
function(callback)
{
fetchingImage(ProductId._id, function(err, res){
pArr['large_image'] = res;
callback(err); //Forgot to add
});
},
function(callback)
{
fetchingBrand(ProductId.brand_id,function(err, res){
pArr['brand'] = res;
callback(err); //Forgot to add
});
},
], function(err){
console.log(pArr); //Edit
temp.push(pArr);
callback(err);
})
}, function(err){
console.log(temp); //This should give you desired result
callback(err);
});

Which actually works perfectly fine in my development environment - However in production (i'm using Openshift) the mongo documents get saved in an endless loop so it looks like the (if (!doc)) condition always return true therefore the document gets created each time. Not sure if this could be a mongoose issue - I also tried the "find" method instead of "findOne". My dev env has node 0.12.7 and Openshift has 0.10.x - this could be the issue, and i'm still investigating - but if anybody can spot an error I cannot see in my logic/code please let me know
thanks!
I solved this issue by using a "series" like pattern and using the shift method on the users array. The mongoose upsert findOneOrCreate is good however if there is a found document, the document is returned, if one isn't found and therefore created, it's also returned. Therefore I could not distinguish between the newly insert doc vs. a found doc, so used the same findOne function which returns null if no doc is found I just create it and send the push notification. Still abit ugly, and I know I could have used promises or the async lib, might refactor in the future. This works for now

Hello Im trying to do associaton with many to many in node using node-orm2.
I have this tables:
project --> id, name
user --> id, name
user_project --> user_fk, project_fk (this is many to many association table)
The controller returns me a list of users and a list of projects, but i need to return in a both another property with projects of every user and users of every prject.
Models:
module.exports = function (orm, db) {
var Project = db.define('project', {
name : { type: 'text', required: true }
},
{
methods: {
serialize: function () {
return {
id : this.id,
name : this.name
};
}
}
});
};
module.exports = function (orm, db) {
var User = db.define('user', {
name : { type: 'text', required: true },
email : { type: 'text', required: true }
},
{
methods: {
serialize: function () {
return {
id : this.id,
name : this.name,
email : this.email
};
}
}
});
};
Controller:
module.exports = {
list: function (req, res, next) {
req.models.project.find().limit(4).order('-created').all(function (err, messages) {
if (err) return next(err);
var projects = messages.map(function (m) {
return m.serialize();
});
console.log(projects);
});
req.models.user.find().limit(4).order('-created').all(function (err, messages) {
if (err) return next(err);
var users = messages.map(function (m) {
return m.serialize();
});
console.log(users);
});
res.sendfile(settings.path + '/public/index2.html');
}
How can I do this I'm confused, I readed the documentation but i don't understand this.
Had some issues with node-orm also...
You can do it with light-orm or bookshelf.js.
In light-orm you can simply extend model with complex request like this:
var SiteCollection = new ORM.Collection({
connector: ORM.driver,
tableName: 'site',
modelExtension: {
getAds: function(callback) {
var query = "SELECT DISTINCT `ads`.* FROM `ads` INNER JOIN `siteads` " +
"ON `ads`.`id` = `siteads`.`ads_id` " +
"WHERE site_id = " + this.get('id');
ORM.Collections.AdsCollection.find(query, callback);
},
renderAds: function(callback) {
var that = this;
this.getAds(function(err, ads) {
var html = ejs.render(adsTemplate, {
content: new ORM.Collection(ads).toJSON()
});
fs.writeFileSync(writeDir + that.get('id') + ".html", html, {
encoding: 'utf8'
});
callback();
});
}
}
});
Try it: https://npmjs.org/package/light-orm
