When trying to render my template, i want to load the data from the server. I'm trying to use Meteor.call but as per the documentation, i'm clearly not in a stub.

If I use Meteor.call inside of an event handler, the response i get back is correct. If i call it within the template.created or similar, i get an undefined response. I guess i could use async call to do it and then render it when available. But is there another way?

I don't want the clients to have direct access to the DB, i want it to come from the server.

//This doesn't work Template.config.created = function() { console.log(Meteor.call('getValue')); //returns undefined }; //This works Template.config.events({ 'blur #button' : function () { console.log(Meteor.call('getValue')); //Prints value }

Any clues?

You need to use a callback in your Meteor.call

Template.config.created = function() { Meteor.call('getValue', function(error, data) { if(error){ //do stuff to handle error } console.log(data); }); };
