Iron Router parameter returns no results - meteor

I'm trying to use a parameter in Iron Router. My url is /activity/dJW9PWJEmSqT3bbSA.
Here's what I have so far:
Router.route('/activity/:_id', function() {
var params = this.params;
console.log(params);
var activityID = params._id;
var currentActivity = Activities.findOne({_id: this.activityID});
this.layout('fullScreen', {
data: {
activity: currentActivity,
activityStarted: false
}
});
this.render('activityDetail');
});
console.log(params) returns [] (0). I'm not sure why.
Any insight would be greatly appreciated.

Try this:
Router.route('/activity/:_id', function() {
this.render('activityDetail',{
data: function(){
return Activities.findOne({_id: this.params._id})
}
});
});

Create a universal helper variable

Is there a way to create a variable at the top of template helpers to remove duplication.
In this particular situation I'm using var candidate = FlowRouter.getParam('id'); and I have to create the variable in each helper. I assume there is a better way.
professionalOverview: function() {
var candidate = FlowRouter.getParam('id');
return ProfessionalOverview.findOne({ candidateUserId: candidate });
},
candidateImg: function() {
var candidateUserId = FlowRouter.getParam('id');
return Files.findOne({ userId: candidateUserId });
},
EDIT
Template.talentProfileNew.onCreated(function() {
var self = this;
self.autorun(function(){
this.candidateUserId = new ReactiveVar(FlowRouter.getParam('id'));
}
});
Template.talentProfileNew.helpers({
candidate: function() {
console.log(Template.instance().candidateUserId.get());
return Meteor.users.findOne({_id: Template.instance().candidateUserId.get()});
}
});
you could read it once in onCreated() and put it in a reactive var. e.g.
Template.Foo.onCreated(function() {
this.candidateUserId = new ReactiveVar(FlowRouter.getParam('id'));
});
Template.Foo.helpers({
candidateImg() {
return ProfessionalOverview.findOne({ userId: Template.instance().candidateUserId.get()});
}
});

How do you do client side routing when saving via methods?

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?

Meteor. Problems with subscribe/publish

i have a problem.
I'm trying to build highcharts graphic.
How it works:
I'm going to my route ('ship.details'), and here i have not problems.
My problem:
subsription to (ships_snapshots_all) not working.
My publish.js:
Meteor.publish("ships_snapshots", function(user, options) {
if(!this.userId) return null;
if(this.userId) {
console.log('subsribed by ' + user);
return ships_snapshots.find({userId: user}, options);
}
});
Meteor.publish("ships_snapshots_all", function() {
return ships_snapshots.find({});
})
My subscribe.js (in lib folder):
Meteor.subscribe('ships_snapshots');
Meteor.subscribe('ships_snapshots_all');
Problem 100% in my subsription, because if i'm installing autopublish all working good. And problem in my router i think.
router.js:
Router.route('/ships/details', {
name: 'ship.details',
loadingTemplate: 'loading',
onBeforeAction: function() {
var shipId = Session.get('currentShipId');
if(!shipId) {
Router.go('user.ships');
} else {
this.next();
}
},
waitOn: function() {
if (Meteor.isClient) {
var getCompare = Meteor.user().profile.wows.compareWith;
console.log(getCompare);
var user2 = Meteor.users.findOne({"profile.wows.nickname": getCompare});
var user2Id = user2._id;
if (getCompare) {
var user2 = Meteor.users.findOne({"profile.wows.nickname": getCompare});
if (user2) {
var user2Id = user2._id;
}
}
if (getCompare) {
var handle = Meteor.subscribe('ships_snapshots', Meteor.user()._id) && Meteor.subscribe('ships_snapshots', user2Id) && Meteor.subscribe('userSearchInfo', getCompare);
Session.set('compareWith', user2);
console.log('user2 _____');
console.log(user2);
return handle
} else {
var handle = Meteor.subscribe('ships_snapshots', Meteor.user()._id) && Meteor.subscribe('ships_snapshots', user2Id);
return handle
}
}, data: function() {
if (handle.ready()) {
var shipname = this.params.shipName;
var obj = {};
var query = ships.findOne();
var shipId = Session.get('currentShipId');
var result;
_.each(Meteor.user().profile.wows.ships, function(row) {
if (row.ship_id === shipId) {
result = row;
}
});
return result;
}
}
});
I think my problem in subscripion for ship_snapshots. Something going wrong here, but i can't to resolve this problem.
What exactly do you mean by "not working"? From your code I would assume that you're always seeing all the ship snapshots.
You shouldn't have the subscribes in /lib if you have them in your router. If you have Meteor.subscribe('ships_snapshots_all'); in /lib then you should always be seeing all the ship snapshots (assuming you're not stopping that subscription anywhere).
Also your subscription to all should be:
Meteor.publish("ships_snapshots", function(user, options) {
if(this.userId) {
console.log('subsribed by ' + user);
return ships_snapshots.find({userId: user}, options);
} else this.ready();
});
You don't want to return null when there is no user, you can just mark the subscription as ready without finding any records. This is not the cause of your problem but just good practice.
Meteor.publish("ships_snapshots", function(user, options) {
if(!this.userId) return null;
if(this.userId) {
console.log('subsribed by ' + user);
return ships_snapshots.find({userId: user._id}, options);
}
});
In your publish script, is user really an id or is it a user object? I changed it to user._id. Please check that.

Meteor define ReactiveVar to be accesible in .events and .helpers

I am trying to define a new ReactiveVar variable to be accessible in all the template sections (ex. .events, .helpers, .rendered ...etc) as shown in my code below, yet I am always getting an error:
Error: Exception in template helper:
ReferenceError: logData is not defined
Can someone please tell me what I am missing / doing wrong here? Thanks
Code:
Template.detailedreport.rendered = function() {
var logData = new ReactiveVar;
logData.set([]);
};
Template.detailedreport.helpers({
myCollection: function () {
return logData.get();
}
});
Template.detailedreport.events({
'submit form': function(e) {
e.preventDefault();
var now = Session.get("startDate");
var then = Session.get("endDate");
var custID = Session.get("customer");
var projID = Session.get("project");
Meteor.call('logSummary', now, then, projID, custID, function(error, data){
if(error)
return alert(error.reason);
logData.set(data);
});
}
});
You need to define the ReactiveVar on the template instance like this :
Template.detailedreport.created = function() {
this.logData = new ReactiveVar([]);
};
Then you'll be able to access it in helpers like this :
Template.detailedreport.helpers({
myCollection: function () {
return Template.instance().logData.get();
}
});
In events you can use the template argument :
Template.detailedreport.events({
'submit form': function(e, template) {
e.preventDefault();
var now = Session.get("startDate");
var then = Session.get("endDate");
var custID = Session.get("customer");
var projID = Session.get("project");
Meteor.call('logSummary', now, then, projID, custID, function(error, data){
if(error){
return alert(error.reason);
}
template.logData.set(data);
});
}
});

Multiple Data Contexts in router - Meteor

I'm building a meteor app and on one route I'm adding multiple data context like so -
this.route('orgPage', {
path: '/org/:title',
data: {
orgs: function () {Orgs.findOne(this.params._id)},
projects: function() {Meteor.subscribe('projects', this.params._id)}
}
The only problem is that when I try to access this data in my templates js file, I can't access the _id or any of the attributes of orgs.
I've tried several approaches, but it always returns undefined. If I use a single data context, it works perfectly. Here is the function that doesn't function properly -
Template.orgPage.events({
'click #newProject': function(e) {
$('#npModal').modal();
},
'submit #npModal form': function(e, template) {
e.preventDefault();
if(!$(e.target).find('[name=newTitle]').val()) {
var projectTitle = 'Untitled'
} else {
var projectTitle = $(e.target).find('[name=newTitle]').val()
}
var theid = this._id;
var newProject = {
title: projectTitle,
organization: theid
}
Meteor.call('project', newProject, function(error, id) {
if (error)
return alert(error.reason);
$('#npModal').modal('hide');
$('#npModal').on('hidden.bs.modal', function (e) {
Router.go('newFields', {});
})
});
});
Anyone have any ideas? Thanks!!
You have missed a return statement. function () {Orgs.findOne(this.params._id)} should be function () {return Orgs.findOne(this.params._id)}. Further more, this inside this function won't refer to what you want, so you can't use this.params. And why do you subscribe to a subscription as a data context property? Do it in the waitOn function instead.
