Meteor, how to access to a helper from another helper?

Question

I have a helper like

Template.user_profile.helpers({   user:function() {      return Meteor.users.find({'profile.front_name':Session.get('slug')}).fetch()[0];   } }); 

I want to add a helper to the collection which could access the user helper and compare its _id with the current user _id, to tell whether the user is visiting its own profile. I'm using something pretty ugly:

Template.user_profile._tmpl_data.helpers.user() 

The final code:

Template.user_profile.helpers({   user:function() {      return Meteor.users.find({'profile.front_name':Session.get('userId')}).fetch()[0];   },   isCurrentUser: function() {     return Template.user_profile._tmpl_data.helpers.user()._id === Meteor.userId();   } }); 

Is there any better way to access another helper?

Answer 1

I've just accidentally discovered this in the console:

Template.registerHelper function (name, func) {                                                                                Blaze._globalHelpers[name] = func;                                                                                    }  

So, Blaze._globalHelpers is what we are looking for!

You can call a template helper (not global helper - which is in outluch's answer) with:

Template.tplName.__helpers.get('helper').call() 

MDG suggests using a regular function and then passing it to helpers, events and so on. See here.

Actually I strongly advise to simply use manuel:viewmodel - it alleviates so many Blaze headaches...
