I have publish code on server-side:
Meteor.publish("getChannelsList", function() {
return News.find({ }, { title: 1 });
});
And subscriptions.js on client:
Meteor.subscribe("getChannelsList", function(err, res) {
if (err) {
throw new Meteor.Error("Subscription error", "Exception in Meteor.subscribe method", err);
}
return res;
});
Collection in it's own "collections" directory
News = new Meteor.Collection("newsStock");
This is my template helper:
Template.channel.helpers({
channels: function() {
return News.find({ }, { title: 1 });
}
});
Autopublish and insecure were removed.
I'm waiting on client database object with "title" and "id" only. If I do in browser debugger News.find().pretty() why I see whole object, with all fields? Removing autopublish is not affect for me.
Can I do multiple publications and subscribes and how it's works?
If you're only intending to return the title, it should be:
Template.channel.helpers({
channels: function() {
return News.find({ }, {
fields: {
title: 1
}
});
}
});
As you point out, this will also publish the _id by default.

I want to save some data and show it in a view template. So I want to do like the example below but using methods.
Template.postSubmit.events({
'submit form': function(e) {
e.preventDefault();
var post = {
url: $(e.target).find('[name=url]').val(),
title: $(e.target).find('[name=title]').val()
};
post._id = Posts.insert(post);
Router.go('postPage', post);
}
});
I tried this:
'insertClubData': function(clubname, capacity, description, homepage){
var currentUserId = Meteor.userId();
var club = {
clubname: clubname,
description: description,
capacity: parseInt(capacity),
homepage: homepage,
createdAt: new Date(),
visitors: 0,
occupancy: 0,
trend: "club-1",
createdBy: currentUserId
}
club._id = clubs.insert(club);
Router.go('club', club);
},
but I get the error:
Exception while invoking method 'insertClubData' TypeError: Object
function router(req, res, next) { I20160425-14:04:55.724(2)? //XXX
this assumes no other routers on the parent stack which we should
probably fix
I understand that this is because Router.go is a client side method. But I also understand that you should avoid server side routing. So what's the most elegant solution?
This is my route:
Router.route('/club/:_id', {
name: 'club',
template: 'club',
data: function(){
return clubs.findOne({_id: this.params._id})
}
});
How about, you call the method from the client and in the callback on success you do the routing. For example:
Template.postSubmit.events({
'submit form': function(e) {
e.preventDefault();
var post = {
url: $(e.target).find('[name=url]').val(),
title: $(e.target).find('[name=title]').val()
};
Meteor.call('insertPost', post, function(error, id) {
if (error) {
alert(error)
} else {
Router.go('postPage', {_id: id});
}
});
}
});
and on the server
Meteor.methods({
insertPost: function(post) {
// do checks
id = Posts.insert(post);
return id;
}
});
Does that work for you?
I have a meteor project where all my users have their own profile page setup in this way using routes:
Routes code:
Router.route('/#:username', {
name: 'profile',
controller: 'ProfileController'
});
ProfileController = RouteController.extend({
template: 'profile',
waitOn: function() {
return Meteor.subscribe('userProfile', this.params.username);
},
data: function() {
var username = Router.current().params.username;
return Meteor.users.findOne({
username: username
});
}
});
Server code:
Meteor.publish('users', function() {
return Meteor.users.find({}, {fields: {username: 1, emails: 1, profile: 1, roles: 1}});
});
Meteor.publish('userProfile', function(username) {
// Try to find the user by username
var user = Meteor.users.findOne({
username: username
});
// If we can't find it, mark the subscription as ready and quit
if (!user) {
this.ready();
return;
}
// If the user we want to display the profile is the currently logged in user
if(this.userId === user._id) {
// Then we return the curresonding full document via a cursor
return Meteor.users.find(this.userId);
} else {
return Meteor.users.find(user._id, {
fields: {
profile: 0
}
});
}
});
I want to do something similar with a pages collection that I've set up. Creating the collection works and the collection page has an _id field that is made upon creation.
Right now the program works nicely for users where mysite.com/# works. Now I want the same thing to work for mysite.com/&
I've basically attempted to do the exact same thing as I did in the above code with the user name but it wasn't working. I've checked to make sure my creation of the collection items are working and they are. But somehow I can't figure out how to do this same thing with collections since I'm relatively new to using routes.
This is what I've attempted:
Here's my routes:
var pageRoute = '/&:_id';
Router.route(pageRoute, {
name: 'page',
controller: 'PageController'
});
PageController = RouteController.extend({
template: 'page',
waitOn: function() {
return Meteor.subscribe('Page', this.params._id);
},
data: function() {
var _id = Router.current().params._id;
return Meteor.pages.findOne({
_id: _id
});
}
});
Server code:
Meteor.publish('pages', function() {
return Pages.find({});
});
Meteor.publish('Page', function(_id) {
// Try find the page by _id
var page = Meteor.pages.findOne({
_id: _id
});
// If we can't find it, mark the subscription as ready and quit
if (!page) {
this.ready();
return;
}
// If the page we want to display is not claimed, display it
if(true) {
return Meteor.pages.find(this._id);
} else {
// Redirect to the page
}
});
The Schema of the Page Collection:
_id: ,
createdAt: ,
CreatedBy: ,
claimedAt: ,
claimedBy: ,
Update:
I've scoped it down to this problem, I get the following error in the console server-side:
I20160202-11:16:24.644(2)? Exception from sub qrPage id 2kY6RKCTuCpBDbuzm TypeError: Cannot call method 'findOne' of undefined

This error occurs whenever I try to direct to mysite.com/&<_id>
Based on this website: https://perishablepress.com/stop-using-unsafe-characters-in-urls/
It looks like # is considered an unsafe character to use in a URL string. On the web page above, it looks like there are several symbols you could use instead as safe characters.
I just tried this on my own machine, and I don't think Meteor plays nicely when the # is introduced in the URL.
This got it working...

New to MeteorJS. I started making a novel Clan/Samurai app to see if I could understand how mongo/meteor and Autoforms handle relationships. I'm trying to make clans and samurai relate to each other so that each Samurai has a specific clan.
I'm attempting to insert the clan data into the Samurai identity. I seem to not be able to.
I've read the following and still seem generally confused on how to implement this. I've tried before, onsuccess, onsubmit hooks. I've attempted to set the schema up so that it works. I mostly get AutoForm undefined or Schema undefined...tons of errors it seems. I've read that it should be client.
I can console log and get it to render but I can't add the new items to the collection.

How to add a relationship or reference with AutoForm in Meteor?
Meteor Autoform package with collection2 does not submit the form
//lib/collections/clans.js
Clans = new Mongo.Collection('clans');
Clans.attachSchema(new SimpleSchema({
name: {
type: String,
label: "Clan Name",
max: 100
}
}));
if (Meteor.isServer) {
Clans.allow({
insert: function (userId, doc) {
return true;
},
update: function (userId, doc, fieldNames, modifier) {
return true;
},
remove: function (userId, doc) {
return true;
}
});
}
//lib/collections/samurais.js
Samurais = new Mongo.Collection('samurais');
Samurais.attachSchema(new SimpleSchema({
title: {
type: String,
label: "Title",
max: 100
},
description: {
type: String,
label: "Description",
optional: true
},
clan: {
type: Clans
}
}));
if (Meteor.isServer) {
Samurais.allow({
insert: function (userId, doc) {
return true;
},
update: function (userId, doc, fieldNames, modifier) {
return true;
},
remove: function (userId, doc) {
return true;
}
});
}
//client/template/clans/createClan.html
<template name="CreateClan">
<h1>Create New Clan</h1>
{{> quickForm
collection="Clans"
id="insertClanForm"
type="insert"
buttonContent="Create"
}}
<div>
{{> ListClans }}
</div>
</template>
//client/main.js
AutoForm.addHooks('insertSamuraiForm', {
before: {
insert: function(doc, template) {
//modify the document here
doc.clanid= 45;
doc.dance ="start again";
console.log("running after hook");
return true;
}
}
});
AutoForm.hooks({
insertSamuraiForm: {
before: {
insert: function(doc, template) {
//modify the document here
doc.projectid= "random";
doc.dance ="start again";
console.log('this is asecond form');
}
}
}
});
I was able to resolve this issue by doing the following.
Return on object using 'before' hook
Router.current().params._id
a. I was using iron router and in my url was clans/_id/samurai/new
added 'dance' and 'clanid' as apart of the simpleschema. I had neglected to include them as apart of the schema so I was getting the console.log to work but not the data to be apart of the object.
//client/lib/main.js (alterations)
before: {
insert: function(doc, template) {
//modify the document here
doc.clanid= Router.current().params._id;
doc.dance ="start again";
console.log("running after hook");
return doc;
}
}
//lib/collections/samurais.js
Samurais = new Mongo.Collection('samurais');
Samurais.attachSchema(new SimpleSchema({
title: {
type: String,
label: "Title",
max: 100
},
description: {
type: String,
label: "Description",
optional: true
},
clanid: {
type: String,
label: "ignore this",
optional: true
},
dance: {
type: String,
optional: true
}
}));
if (Meteor.isServer) {
Samurais.allow({
insert: function (userId, doc) {
return true;
},
update: function (userId, doc, fieldNames, modifier) {
return true;
},
remove: function (userId, doc) {
return true;
}
});
}
I have a iron route that searches for a collection item based on the url param. If it finds it, it returns the item as a data context, otherwise it renders a notFound template. The code looks like this:
this.route('profileView', {
path: list_path + '/profiles/:_id',
fastRender: true,
waitOn: function() {
if (Meteor.user()) {
return [Meteor.subscribe('singleProfile', this.params._id, Session.get("currentListId"))];
}
},
data: function() {
var profile = Profiles.findOne({
_id: this.params._id
});
if (!profile) {
this.render("notFound");
} else
return profile;
}
});
The problem is the notFound template gets loaded briefly prior to profile getting returned, although I thought the waitOn function would have handled that. What's the correct pattern to have the desired result using iron router? Thanks.
Is it possible that you forgot to configure the loading and dataNotFound hooks?
Router.onBeforeAction('loading');
Router.onBeforeAction('dataNotFound');
If you want to understand what is actually going on here, please look here.
I had to check for this.ready() in data. Updated code
this.route('profileView', {
path: list_path + '/profiles/:_id',
fastRender: true,
waitOn: function() {
if (Meteor.user()) {
return [Meteor.subscribe('singleProfile', this.params._id, Session.get("currentListId"))];
}
},
data: function() {
if(this.ready()){
var profile = Profiles.findOne({
_id: this.params._id
});
if (!profile) {
this.render("notFound");
} else
return profile;
}
}
});
I am using Meteor 0.8 and iron-router.
I have a single route that I use to subscribe to a number of collections. What I would like to do is create a document when you arrive on the route and then subscribe to it so I can access it.
This is my route:
this.route('product_collection', {
path: '/collection/:collection',
template: 'product_collection',
layoutTemplate: 'layout-new',
waitOn: function() { return [ Meteor.subscribe('specific_product_collection', this.params.collection), Meteor.subscribe('product_types')] },
data: function () { return ProductCollections.findOne({ url: this.params.collection }) },
onBeforeAction: function(pause){
//Prevent double rendering
if (this.ready()) {
var productType = ProductTypes.findOne({url: this.params.collection })
console.log(productType)
if(productType){
var product = {
productType: productType._id
};
Session.set("productTypeId", productType._id);
Products.insert(product, function(error, id) {
if (error) {
console.error(error);
set_notification('Oops, something went wrong.', 'Please try again later.');
} else {
Session.set("productId", id);
Session.set("productName", productType.name );
//Not working
Meteor.subscribe('specific-product', id);
console.log('should be subscribed')
}
});
}
} else {
console.log('loading')
this.render('loading');
pause();
}
},
});
Ok,
I found out the ID was different on the server vs client side location. So ended up writing a meteor method call on the server.
See reference: Retrieve _id after insert in a Meteor.method call
