Accessing template level subscription inside event handler - syntax?

help
1

I am having trouble accessing a subscription inside an event handler:

on the SERVER, I am publishing:

Meteor.publish('basicInfoPub',function() {
   
    if (!this.userId) {
        return this.ready();
    }
    return BasicInfo.find(
        {  userId:this.userId },
        { fields: {firstName:1, lastName:1, middleName:1, someCodes:1}
    });

});

On the CLIENT, am subscribing, and then trying to access the subscription data in an event handler.

Template.basicInfo.onCreated(function(){

    basicInfoSub = this.subscribe('basicInfoPub');

});

//event handler
    'click #populateFormButton': function(e,instance){
        if(instance){
            $('#firstName').val(instance.data.basicInfoSub.firstName); 
            $('#lastName').val(instance.data.lastName);
            $('#middleName').val(instance.basicInfoSub.middleName);
        }
    }

In the event handler, none of the 3 options shown actually work (instance.data, instance.basicInfoSub, or instance.data.basicInfoSub). How do I access firstName, lastName etc inside the event handler?

Thanks!

You don’t need to access the template instance. The data that is returned by the subscription goes into the (globally accessible) client-side cache, minimongo. All you need to do to get the data on the client is:

'click #populateFormButton': function(e, instance){
  var basicInfo = BasicInfo.findOne({_id: Meteor.userId()});
  instance.$('#firstName').val(basicInfo.firstName); 
  instance.$('#lastName').val(basicInfo.lastName);
  instance.$('#middleName').val(basicInfo.middleName);
 }

This is assuming the data has been returned from the subscription by the time the user clicks the button (pretty safe bet).

Also note the instance.$ rather than $, so the scope in which jquery searches is limited to html in that particular template instance.

(The BasicInfo collection should be instantiated on both client and server.)
