Meteorjs - Passing data context to Template Rendered function?

问题

I have these data context and I want to use JQuery to set the selected value in the tag based on the value.

I am having problem passing the return data from the helpers into the Template.Rendered function.

is there any way of doing that?

Helpers

Template.studentSetting.helpers({
  values: function(){
    return Basics.findOne({userId:Meteor.userId()});
  }
});

Rendered function

Template.studentSetting.rendered = function(){
 //I want to use the "values" helper data here and perform some jquery code based on that?? 
}

According to this post, I would advise doing what mpowaga suggests in the thread and just define the helper outside:

var valuesFunc = function () {
  return Basics.findOne({userId:Meteor.userId()});
};

Template.studentSetting.helpers({
  values: valuesFunc
});

Template.studentSetting.onRendered(function(){
  var values = valuesFunc();
});

You need to call your studentSettings template with an argument like this:

{{> studentSettings inheritedValues=values}}

You can then access it into your Rendered function like this:

Template.studentSetting.rendered = function(){
 var values = this.data.inheritedValues;
 console.table(values);
}
