Custom menu with roles

i want something like this

{{# if role.admin}}
<a href="/secret">only for all admin users</a>
{{/if}}

in my _header.html template, i use iron-roter, roles, and meteor-useraccount

maybe like (in _header.js)

Template._header.helpers({

  currentRole: function(){
      return Meteor.call('meteor_get_me_my_current_role')
  }

})

Any idea? Thanks

Meteor.call on the client is asynchronous, so you need to provide a callback function for the method results. Secondly you need to take care of reactivity or your _header template might not get the update. One way could be like this (assuming meteor_get_me_my_current_role returns a role object)

Template._header.onCreated(function(){
 this.initialized = new ReactiveVar(false);
 this.role = new ReactiveVar({admin: false});
});
Template._header.helpers({
 currentRole: function() {
  var template = Template.instance();
  if(!template.initialized.get())
  {
   Meteor.call('meteor_get_me_my_current_role', function(err,res) {
    if(!err) {
     template.role.set(res);
     template.initialized.set(true);
    }
   });
  }
  return template.role.get();
 }
});
