access Meteor.users from template.onRendered

I need to execute this piece of code

Template.addPost.onRendered ->
@$('#name').val(Meteor.user().profile.name)

But it seems that the template is rendered earlier than Users collection gets populated on the Client. Thus returning me 

Cannot read property 'profile' of undefined

How do I tackle this?

You can wait for the user to be loaded via an autorun:

Template.addPost.onRendered ->
  @autorun (c) ->
    # extract the name in a safe way
    {name} = Meteor.user()?.profile

    # once a name has been found, update the DOM and stop the autorun
    if name
      # note that name is an id so we don't need @$
      $('#name').val name
      c.stop()

We are also taking advantage of coffeescript's existential operator to safely extract the name value. In javascript this solution would look something like this:

Template.addPost.onRendered(function() {
  this.autorun(function(c) {
    var user = Meteor.user()
    var name = user && user.profile && user.profile.name;
    if (name) {
      $('#name').val(name);
      c.stop();
    }
  });
});
