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

I have some functionality in a onRendered event that I want to run on every render.
Template.DashboardCoachPost.onRendered(function () {
var post, postId;
this.autorun(function() {
postId = Router.current().params.query.p;
reactive.isSubmitted.set(false);
if (Template.instance().subscriptionsReady()) {
post = Posts.find({_id: postId}).fetch()[0];
reactive.post.set(post);
if (post) {
reactive.isSubmitted.set(true);
}
}
});
});
In my RouterController I have:
DashboardCoachPostController = RouteController.extend({
subscriptions: function() {
this.postId = Router.current().params.query.p;
if (this.handle) {
this.handle.stop();
}
if (this.postId) {
this.handle = this.subscribe('posts', { postId: this.postId });
}
}
});
and my route:
Router.route('/dashboard/coach/post', {
name: 'dashboardCoachPost',
controller: DashboardCoachPostController,
where: 'client',
layoutTemplate: 'LegalLayout'
});
I have a feeling that I am not handling subscriptions properly, but I can't figure out how to get my post without this method.
Template.instance().subscriptionsReady() is used when you subscribe in a template instance. But you are subscribing in the router.
You have to choose if you let the template instance handle the subscription or the router.
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...

I am trying to get two variable from the iron router so that I can essentially call them in my temlate such as {{user.telephone}} and {{pic.profilepic}}.
My code in the router is as follows. (Does Not Work!)
Router.route('/profile/:_id', {
name: 'profile',
template: 'profile',
data:function(){
return {
user:Info.findOne({_id:this.params._id}),
pic: Profilepics.findOne({_id:this.params._id})
};
},
subscriptions: function(){
return {
Meteor.subscribe("userInfo"),
Meteor.subscribe( "profilepic");
},
action:function (){
if (this.ready()){
this.render();
}else {
this.render('loading');
}
}
});
I able to do just one variable with the following code. i.e get {{user.telephone}}. Any chance anyone can help me get both variable instead of just one?
enterRouter.route('/profile/:_id', {
name: 'profile',
template: 'profile',
data:function(){
return {
user:Info.findOne({_id:this.params._id})
};
},
subscriptions: function(){
return Meteor.subscribe("userInfo")
},
action:function (){
if (this.ready()){
this.render();
}else {
this.render('loading');
}
}
});
If you are using the latest version of iron router, i suggest you update the code to something a bit more modern.
First you create a general app controller:
ApplicationController = RouteController.extend({
layoutTemplate: 'DefaultLayout',
loadingTemplate: 'loading_template',
notFoundTemplate: '404_template',
});
Then you start to extend it for different purposes:
ProfileController = ApplicationController.extend({
show_single: function() {
this.render('profile');
}
});
After this you can create your routes for the profile part
Router.route('/profile/:_id', {
controller: 'ProfileController',
action: 'show_single',
waitOn: function() {
return [
Meteor.subscribe("userInfo"),
Meteor.subscribe("profilepic")
];
},
subscriptions: function() {
this.subscribe("somethingyoudontneedtowaitfor", this.params._id);
},
data: function() {
if (this.ready()) {
return {
user: Info.findOne({
_id: this.params._id
}),
pic: Profilepics.findOne({
_id: this.params._id
})
};
}
}
});
It might be a bit more code, but it gives you complete control over what it does. Also, using this, while the router is waiting for the subscriptions to be ready, it displays the loading template defined above. If you don't want to display the loading, you move the subscriptions out of waiton.
Return multiple subscriptions as an array from subscriptions function,
Use return [
Meteor.subscribe("userInfo"),
Meteor.subscribe( "profilepic")
];
instead of
return { Meteor.subscribe("userInfo"), Meteor.subscribe( "profilepic"); which has {} mismatch.
In a similar situation I have
data: function() {
var gridId = this.params._gridId;
return (People.find({gridId: gridId})
&& GridLog.find({gridId: gridId}));
},
with the subscribe calls in the waitOn() handler as part of the Boolean status
waitOn: function() {
return (Meteor.subscribe('people', this.params._gridId)
&& Meteor.subscribe('gridlog', this.params._gridId) );
},
You may have more success just &&ing them together in waitOn() (as strange as that seems).
I have the following meteor method
hasNoPendingPayments: function() {
var userId = Meteor.userId();
console.log(userId); <---------------------- correctly logs userId
var user = Users.findOne({_id: userId }, { fields: { services: 0 } });
console.log(user); <-------------------------- logs 'undefined'
return hasNoPendingPayments(user);
},
This private helper I call from the above
hasNoPendingPayments = function(user) {
// console.log('hasNoPendingPayments ');
// console.log(user);
var payments = Payments.find({ userId: user._id, status: {
$in: [Payments.States.PENDING, Payments.States.PROCESSING]}
});
return payments.count() === 0;
};
And I call it from the client here
Template.payments.created = function() {
this.hasNoPendingPayments = new ReactiveVar(false);v
};
Template.payments.rendered = function () {
Session.set('showPaymentRequestForm', false);
var self = this;
Meteor.call('hasNoPendingPayments', function(error, result) {
if (result === true) { self.hasNoPendingPayments.set(true); }
});
...
However, I get an undefined error on the server when I load the template initially (I marked where in code). Although, when I try call the same query on the client with the same userId, i correctly gets the user record
Any idea as to why this is?
Try with this.
Template.payments.rendered = function () {
Session.set('showPaymentRequestForm', false);
var self = this;
if(Meteor.userId()){
Meteor.call('hasNoPendingPayments', function(error, result) {
if (result === true) { self.hasNoPendingPayments.set(true); }
});
}else{
console.log("Seems like user its not logged in at the moment")
}
Maybe when you make the Meteor.call, the data its not ready
Also just to be sure, when you run Users.findOne({_id: userId }, { fields: { services: 0 } }); on console.log what you get?
Maybe the find is wrong or have some typo
update
Router.map(function()
{
this.route('payments',
{
action: function()
{
if (Meteor.userId())
this.render();
} else{
this.render('login') // we send the user to login Template
}
}
}
or waitOn
Router.map(function () {
this.route('payments', {
path: '/payments',
waitOn: function(){
return Meteor.subscribe("userData"); //here we render template until the subscribe its ready
}
});
});
Meteor stores all the user records in Meteor.users collection
so try Meteor.users.findOne({_id: userId }....)
Instead of Users.findOne({_id: userId }, { fields: { services: 0 } });
in your server method
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;
}
}
});
