I'm a bit new to Meteor and something I'm having trouble with is reactive data -- particularly in instances where I need to change the data shown based on a mouse or keyboard event. Doing this kind of stuff the normal js way seems to give me trouble in meteor since everything I change gets re-rendered and reset constantly.
So, I thought I'd see if this would be a case in which I could use Meteor's Deps object, however I can't quite grasp it. Here's the code I'm using:
(function(){
var tenants = [];
var selectedTenant = 0;
var tenantsDep = new Deps.Dependency;
Template.tenantsBlock.tenantsList = function()
{
tenants = [];
var property = $properties.findOne({userId: Meteor.userId(), propertyId: Session.get('property')});
var tenancies = _Utils.resolveTenancies(property, true, null, true);
for(var i = 0; i < tenancies.length; i++)
{
if(tenancies[i].tenancyId == Session.get('tenancy'))
{
tenants = tenants.concat(tenancies[i].otherTenants, tenancies[i].primaryTenant);
}
}
tenants[selectedTenant].selected = 'Selected';
tenantsDep.changed();
return tenants;
};
Template.tenantsBlock.onlyOneTenant = function()
{
tenantsDep.depend();
return tenants.length > 1 ? '' : 'OneChild';
};
Template.tenantsBlock.phoneNumber = function()
{
tenantsDep.depend();
for(var i = 0; i < tenants[selectedTenant].details.length; i++)
if(_Utils.getDynamicContactIconClass(tenants[selectedTenant].details[i].key) == 'Phone')
return tenants[selectedTenant].details[i].value;
return null;
};
Template.tenantsBlock.emailAddress = function()
{
tenantsDep.depend();
for(var i = 0; i < tenants[selectedTenant].details.length; i++)
if(_Utils.getDynamicContactIconClass(tenants[selectedTenant].details[i].key) == 'Email')
return tenants[selectedTenant].details[i].value;
return null;
};
Template.tenantsBlock.addedDate = function()
{
tenantsDep.depend();
return _Utils.timeToDateString(tenants[selectedTenant].created);
};
Template.tenantsBlock.events({
'click .Name': function(e, template)
{
tenantsDep.depend();
var _this = e.currentTarget;
var tenantName = _this.innerHTML;
$(_this).addClass('Selected');
$(_this).siblings().removeClass('Selected');
for(var i = 0; i < tenants.length; i++)
{
if(tenants[i].name == tenantName)
tenants[i].selected = "Selected";
else
tenants[i].selected = '';
}
}
})
})();
^This seemed to be what they were getting at in the meteor documentation (http://docs.meteor.com/#deps_dependency) for dependency.changed() and dependency.depend(), but all this does is give me an infinite loop.
So can I modify the way I declare deps to get this to make data reactive? Is there a better way to do this all together?
UPDATE:
Although I was skeptical to do so, I've been inclined to try to use Session.set/Session.get in a localized way. So, the next time I have to do this, I'll just do
Session.set('tenantsBlock' {tenants: [], selectedTenant: 0});
and then just access this variable from within helpers and event maps related to Template.tenantsBlock. That way they all have real time access to the data and they all get re-run when the data changes. Here's what I converted this script into (sorry these are both so large):
(function()
{
Template.tenantsBlock.created = Template.tenantsBlock.destroyed =function()
{
_Utils.setSession('tenantsBlock', {
tenants: [],
selectedTenant: 0
})
};
Template.tenantsBlock.tenantsList = function()
{
var localContext = Session.get('tenantsBlock');
localContext.tenants = [];
var property = $properties.findOne({userId: Meteor.userId(), propertyId: Session.get('property')});
var tenancies = _Utils.resolveTenancies(property, true, null, true);
for(var i = 0; i < tenancies.length; i++)
{
if(tenancies[i].tenancyId == Session.get('tenancy'))
{
localContext.tenants = localContext.tenants.concat(tenancies[i].otherTenants, tenancies[i].primaryTenant);
break;
}
}
localContext.tenants[localContext.selectedTenant].selected = 'Selected';
Session.set('tenantsBlock', localContext);
return localContext.tenants;
};
Template.tenantsBlock.onlyOneTenant = function()
{
var localContext = Session.get('tenantsBlock');
return localContext.tenants.length > 1 ? '' : 'OneChild';
};
Template.tenantsBlock.phoneNumber = function()
{
var localContext = Session.get('tenantsBlock');
for(var i = 0; i < localContext.tenants[localContext.selectedTenant].details.length; i++)
if(_Utils.getDynamicContactIconClass(localContext.tenants[localContext.selectedTenant].details[i].key) == 'Phone')
return localContext.tenants[localContext.selectedTenant].details[i].value;
return null;
};
Template.tenantsBlock.emailAddress = function()
{
var localContext = Session.get('tenantsBlock');
var selectedTenantDetails = localContext.tenants[localContext.selectedTenant].details;
for(var i = 0; i < selectedTenantDetails.length; i++)
if(_Utils.getDynamicContactIconClass(selectedTenantDetails[i].key) == 'Mail')
return selectedTenantDetails[i].value;
return null;
};
Template.tenantsBlock.addedDate = function()
{
var localContext = Session.get('tenantsBlock');
return _Utils.timeToDateString(localContext.tenants[localContext.selectedTenant].created);
};
Template.tenantsBlock.events({
'click .Name': function(e, template)
{
var localContext = Session.get('tenantsBlock');
var _this = e.currentTarget;
var tenantName = _this.innerHTML;
for(var i = 0; i < localContext.tenants.length; i++)
{
if(localContext.tenants[i].name == tenantName)
{
localContext.tenants[i].selected = 'Selected';
localContext.selectedTenant = i;
}
else
{
localContext.tenants[i].selected = '';
}
}
Session.set('tenantsBlock', localContext);
}
})
})();
You'll have to overcome the old-school way of doing it :) Meteor is a lot simpler than you think. A good rule of thumb is that if you're using jQuery to manipulate any DOM elements, you're probably doing it wrong. Additionally, if you're accessing any data without using the collection API, you'd better have good reason to do so.
In your case, you don't need to code up any manual dependencies at all. Manual dependencies are rarely needed in most Meteor applications.
The first thing you need to do is put all your tenants inside a Meteor.Collection, which will make them easier to work with.
Tenants = new Meteor.Collection("tenants");
Your tenantsBlock template should look something like this (modulo some different html elements):
<template name="tenantsBlock">
<ol>
{{#each tenants}}
<li class="name {{selected}}">
<span>Primary Tenant: {{primaryTenant}}</span>
<span>Other Tenants: {{otherTenants}}</span>
<span>Phone Number: {{phoneNumber}}</span>
<span>Email Address: {{emailAddress}}</span>
<span>Added Date: {{addedDate}}</span>
</li>
{{/each}}
</ol>
</template>
Each document in Tenants should look something like the following:
{
primaryTenant: "Joe Blow",
otherTenants: "Mickey Mouse, Minnie Mouse",
phoneNumber: "555-234-5623",
emailAddress: "joe.blow#foo.com",
addedDate: "2005-10-30T10:45Z"
}
Then, all the code you would need is just for the selection/deselection, and you can delete everything else:
Template.tenantsBlock.tenants = function() {
return Tenants.find();
};
Template.tenantsBlock.selected = function() {
return Session.equals("selectedTenant", this._id);
};
Template.tenantsBlock.events({
'click .name': function(e) {
Session.set("selectedTenant", this._id);
}
});
Once again, I reiterate that you should never be doing DOM manipulations with Javascript when using Meteor. You just update your data and your templates will reactively update if everything is done correctly. Declare how you want your data to look, then change the data and watch the magic.
Meteor has really evolved since I posted this back in 2013. I thought
I should post a modern, superior method.
For a while now you've been able to create a ReactiveVar and now you can append those directly to templates. A ReactiveVar, similar to Session, is a reactive data store. ReactiveVar, however, holds only a single value (of any type).
You can add ReactiveVar to the client side of your project by running this in your terminal from your app's root directory:
$meteor add reactive-var
This javascript shows how you can pass the variable between the template's onCreated, onRendered, onDestroyed, events and helpers.
Template.myTemplate.onCreated = function() {
// Appends a reactive variable to the template instance
this.reactiveData = new ReactiveVar('Default Value');
};
Template.myTemplate.events({
'click .someButton': (e, template) => {
// Changes the value of the reactive variable for only this template instance
template.reactiveData.set('New Value');
},
});
Template.myTemplate.helpers({
theData: () => {
// Automatically updates view when reactive variable changes
return Template.instance().reactiveData.get();
},
});
This is superior for a few reasons:
It scopes the variable only to a single template instance. Particularly useful in cases where you might have a dozen instances of a template on a page, all requiring independent states.
It goes away when the template goes away. Using ReactiveVar or Session variables you will have to clear the variable when the template is destroyed (if it is even destroyed predictably).
It's just cleaner code.
Bonus Points: See ReactiveDict for cases in which you have many instances of a template on a page at once, but need to manage a handful of reactive variables and have those variables persist during the session.

I would like to count how many entreprise are in some category but I'm stuck with the asynchrone concept.
Here's what I already have:
Category.getall(function(err, cat){
if(err) return res.negotiate(err);
catIds = []
for( var iCat in cat){
catIds.push(cat[iCat].id)
// and here I would like do something like
Entreprise.count({category_id: cat[iCat].id}, function(err, nbr){
categoriesOUT.push({categorie: cat, entreprise_number: nbr })
// I know that i can not do it but it's just to help to understand the logic I would like to have.
if(cat.length==iCat){
return res.json({categories: categoriesOUT})
}
})
}
})
There are a couple of ways to handle this. One would be to bring in a promise library like Q. Another would be a single database call that can count up enterprise objects grouped by category_id... however, I think that would go beyond Waterline's normal queries, you would have to use .query or .native or something.
The easiest quick fix for you is to just keep a counter of how many results you have handled. You may get tired of this approach after using it a couple of times, but it would look something like this:
Category.getall(function(err, cat){
if(err) { return res.negotiate(err); }
var catIds = [], categoriesOut = [], processedCategories = 0;
for( var iCat in cat){
catIds.push(cat[iCat].id)
Entreprise.count({category_id: cat[iCat].id}, function(err, nbr) {
if (err) {
categoriesOUT.push({categorie: cat, entreprise_number: 0});
} else {
categoriesOUT.push({categorie: cat, entreprise_number: nbr });
}
processedCategories += 1;
if (processedCategories >= cat.length) {
return res.json({categories: categoriesOUT});
}
});
}
});
Here's how I finaly get it only with MySQL request as suggered by #arbuthnott
(The category field is call domaine here)
Domaine.getall(function(err, domaines){
if(err){return res.negotiate(err)}
var domNames = {}, domContain = {}, domOut = [];
Entreprise.query('SELECT domaine_id, COUNT(*) FROM entreprise GROUP BY domaine_id', function(err, entreprises){
if(err){return res.negotiate(err)}
entreprises = JSON.parse(JSON.stringify(entreprises));
for(var ent of entreprises){
domContain[ent['domaine_id']] = ent['COUNT(*)'];
}
for(var iDom in domaines){
var countAdded = false;
for(var dc in domContain){
if(dc==domaines[iDom].id) {
domaines[iDom].entreprises_count = domContain[dc];
countAdded = true;
}
}
if(!countAdded) domaines[iDom].entreprises_count = 0;
}
res.json({domaines:domaines})
})
})

Trying to load audio buffers into memory. When I hit localhost:3000/tides or localhost:3000 it loads my buffers into memory with no problems. When I then click through onto a session e.g. localhost:3000/tides/SOMESESSIONID. the buffers have already loaded from the previous state.
However, when I then refresh the page on "localhost:3000/tides/SOMESESSIONID" the buffers don't load properly and the console just logs an array of file path names.

Okay so i got a reply on the meteor forums!
https://forums.meteor.com/t/script-doesnt-load-web-audio-buffers-properly-on--id-routes/15270
"it looks like your problem is relative paths, it's trying to load your files from localhost:3000/tides/ghost_*.wav if you change line 58 of your router to go up a directory for each file it should work.
loadDrums(["../ghost_kick.wav", "../ghost_snare.wav", "../zap.wav", "../ghost_knock.wav"]);
This did the trick. Seems odd that Meteor can load stuff fine without using '../' in one route but not in another but there we go. Hope this helps someone in the future.
I have been working on a end-to-end test using Webdriver I/O from Jasmine. One specific scenario has been giving me significant challenges.
I have a page with 5 links on it. The number of links actually challenges as the page is dynamic. I want to test the links to see if each links' title matches the title of the page that it links to. Due to the fact that the links are dynamically generated, I cannot just hard code tests for each link. So, I'm trying the following:
it('should match link titles to page titles', function(done) {
client = webdriverio.remote(settings.capabilities).init()
.url('http://www.example.com')
.elements('a').then(function(links) {
var mappings = [];
// For every link store the link title and corresponding page title
var results = [];
for (var i=0; i<links.value.length; i++) {
mappings.push({ linkTitle: links.value[0].title, pageTitle: '' });
results.push(client.click(links.value[i])
.getTitle().then(function(title, i) {
mappings[i].pageTitle = title;
});
);
}
// Once all promises have resolved, compared each link title to each corresponding page title
Promise.all(results).then(function() {
for (var i=0; i<mappings.length; i++) {
var mapping = mappings[i];
expect(mapping.linkTitle).toBe(mapping.pageTitle);
}
done();
});
});
;
});
I'm unable to even confirm if I'm getting the link title properly. I believe there is something I entirely misunderstand. I am not even getting each links title property. I'm definately not getting the corresponding page title. I think I'm lost in closure world here. Yet, I'm not sure.
UPDATE - NOV 24
I still have not figured this out. However, i believe it has something to do with the fact that Webdriver I/O uses the Q promise library. I came to this conclusion because the following test works:
it('should match link titles to page titles', function(done) {
var promise = new Promise(function(resolve, reject) {
setTimeout(function() { resolve(); }, 1000);
});
promise.then(function() {
var promises = [];
for (var i=0; i<3; i++) {
promises.push(
new Promise(function(resolve, reject) {
setTimeout(function() {
resolve();
}, 500);
})
);
}
Promise.all(promises).then(function() {
expect(true).toBe(true)
done();
});
});
However, the following does NOT work:
it('should match link titles to page titles', function(done) {
client = webdriverio.remote(settings.capabilities).init()
.url('http://www.example.com')
.elements('a').then(function(links) {
var mappings = [];
// For every link store the link title and corresponding page title
var results = [];
for (var i=0; i<links.value.length; i++) {
mappings.push({ linkTitle: links.value[0].title, pageTitle: '' });
results.push(client.click(links.value[i])
.getTitle().then(function(title, i) {
mappings[i].pageTitle = title;
});
);
}
// Once all promises have resolved, compared each link title to each corresponding page title
Q.all(results).then(function() {
for (var i=0; i<mappings.length; i++) {
var mapping = mappings[i];
expect(mapping.linkTitle).toBe(mapping.pageTitle);
}
done();
});
})
;
});
I'm not getting any exceptions. Yet, the code inside of Q.all does not seem to get executed. I'm not sure what to do here.
Reading the WebdriverIO manual, I feel like there are a few things wrong in your approach:
elements('a') returns WebElement JSON objects (https://code.google.com/p/selenium/wiki/JsonWireProtocol#WebElement_JSON_Object) NOT WebElements, so there is no title property thus linkTitle will always be undefined - http://webdriver.io/api/protocol/elements.html
Also, because it's a WebElement JSON object you cannot use it as client.click(..) input, which expects a selector string not an object - http://webdriver.io/api/action/click.html. To click a WebElement JSON Object client.elementIdClick(ID) instead which takes the ELEMENT property value of the WebElement JSON object.
When a client.elementIdClick is executed, the client will navigate to the page, trying to call client.elementIdClick in the next for loop cycle with next ID will fail, cause there is no such element as you moved away from the page. It will sound something like invalid element cache.....
So, I propose another solution for your task:
Find all elements as you did using elements('a')
Read href and title using client.elementIdAttribute(ID) for each of the elements and store in an object
Go through all of the objects, navigate to each of the href-s using client.url('href'), get the title of the page using .getTitle and compare it with the object.title.
The source I experimented with, not run by Jasmine, but should give an idea:
var client = webdriverio
.remote(options)
.init();
client
.url('https://www.google.com')
.elements('a')
.then(function (elements) {
var promises = [];
for (var i = 0; i < elements.value.length; i++) {
var elementId = elements.value[i].ELEMENT;
promises.push(
client
.elementIdAttribute(elementId, 'href')
.then(function (attributeRes) {
return client
.elementIdAttribute(elementId, 'title')
.then(function (titleRes) {
return {href: attributeRes.value, title: titleRes.value};
});
})
);
}
return Q
.all(promises)
.then(function (results) {
console.log(arguments);
var promises = [];
results.forEach(function (result) {
promises.push(
client
.url(result.href)
.getTitle()
.then(function (title) {
console.log('Title of ', result.href, 'is', title, 'but expected', result.title);
})
);
});
return Q.all(promises);
});
})
.then(function () {
client.end();
});
NOTE:
This fails to solve your problem, when the links trigger navigation with JavaScript event handlers not the href attributes.
I am trying to make a newsfeed similar to twitter, where new records are not added to the UI (a button appears with new records count), but updates, change reactively the UI.
I have a collection called NewsItems and I a use a basic reactive cursor (NewsItems.find({})) for my feed. UI is a Blaze template with a each loop.
Subscription is done on a route level (iron router).
Any idea how to implement this kind of behavior using meteor reactivity ?
Thanks,
The trick is to have one more attribute on the NewsItem Collection Say show which is a boolean. NewsItem should have default value of show as false
The Each Loop Should display only Feeds with show == true and button should show the count of all the items with show == false
On Button click update all the elements in the Collection with show == false to show = true
this will make sure that all your feeds are shown .
As and when a new feed comes the Button count will also increase reactively .
Hope this Helps
The idea is to update the local collection (yourCollectionArticles._collection): all articles are {show: false} by default except the first data list (in order not to have a white page).
You detect first collection load using :
Meteor.subscribe("articles", {
onReady: function () {
articlesReady = true;
}
});
Then you observe new added data using
newsItems = NewsItems.find({})
newsItems.observeChanges({
addedBefore: (id, article, before)=> {
if (articlesReady) {
article.show = false;
NewsItems._collection.update({_id: id}, article);
}
else {
article.show = true;
NewsItems._collection.update({_id: id}, article);
}
}
});
Here is a working example: https://gist.github.com/mounibec/9bc90953eb9f3e04a2b3.
Finally I managed it using a session variable for the current date /time:
Template.newsFeed.onCreated(function () {
var tpl = this;
tpl.loaded = new ReactiveVar(0);
tpl.limit = new ReactiveVar(30);
Session.set('newsfeedTime', new Date());
tpl.autorun(function () {
var limit = tpl.limit.get();
var time = Session.get('newsfeedTime');
var subscription = tpl.subscribe('lazyload-newsfeed', time, limit);
var subscriptionCount = tpl.subscribe('news-count', time);
if (subscription.ready()) {
tpl.loaded.set(limit);
}
});
tpl.news = function() {
return NewsItems.find({creationTime: {$lt: Session.get('newsfeedTime')}},
{sort: {relevancy: -1 }},
{limit: tpl.loaded.get()});
},
tpl.countRecent = function() {
return Counts.get('recentCount');
},
tpl.displayCount = function() {
return Counts.get('displayCount');
}
});
Template.newsFeed.events({
'click .load-new': function (evt, tpl) {
evt.preventDefault();
var time = new Date();
var limit = tpl.limit.get();
var countNewsToAdd = tpl.countRecent();
limit += countNewsToAdd;
tpl.limit.set(limit);
Session.set('newsfeedTime', new Date());
}
});

NOW I try to do this in my app (thx to Akshat)
//common
LANG = 'ru';
Dictionary = new Meteor.Collection("dictionary");
//if server
Meteor.startup(function () {
if (Dictionary.find().count() === 0) {
// code to fill the Dictionary
}
});
Meteor.publish('dictionary', function () {
return Dictionary.find();
});
//endif
//client
t = function(text) {
if (typeof Dictionary === 'undefined') return text;
var res = Dictionary.find({o:text}).fetch()[0];
return res && res.t;
}
Meteor.subscribe('dictionary', function(){
document.title = t('Let the game starts!');
});
Template.help.text = t('How to play');
//html
<body>
{{> help}}
</body>
<template name="help">
{{text}}
</template>
Still doesn't work as we wanted: when templates are rendered Dictionary was undefined. Butt('How to play') in console works perfectly )
Javascript variables aren't shared between the client and server reactively. You have to use a Meteor Collection to store your data e.g
if (Meteor.isServer) {
var Dictionary = new Meteor.Collection("dictionary");
if(Dictionary.find().count() == 0) {
//If the 'dictionary collection is empty (count ==0) then add stuff in
_.each(Assets.getText(LANG+".txt").split(/\r?\n/), function (line) {
// Skip comment lines

In the above i'm assuming you have the autopublish package in (its in by default when you create a package so this shouldn't really bother you, but just in case you removed)
With your document title you would have to use a slightly different implementation because remember the data wouldn't be downloaded at the time Meteor.startup is run, since the html and javascript are downloaded first & the data is empty, then the data comes in slowly (and then reactively fills the data up)
