Meteor template.rendered and this.data access
I have a template
<template name='order'>
{{vendor.name}}
</template>
rendered with
Template.order.vendor = function () {
return {name: 'Chanel', address: 'Paris' };
};
When I try to access this.data in
Template.order.rendered = function () {
console.log(this.data);
};
I get 'undefined'.
What is the correct way of getting eg vendor.name and vendor.address in Template.order.rendered ?
Thank you.
In Template.rendered, this.data corresponds to the data the template was "fed" with, either as a parameter or using the {{#with}} construct. vendor is just a helper function returning data available in the order template, but not binded to "this.data". SO to solve your problem, you have a number of options :
Defining a parent template and moving the vendor helper to this parent, then you can alternatively call order with vendor as a parameter or use a {{#with block}}
<template name="parent">
{{> order vendor}}
{{#with vendor}}
{{> order}}
{{/with}}
</template>
<template name="order">
{{name}}
</template>
Template.parent.vendor=function(){
return{
name:"Chanel",
address:"Paris"
};
};
Template.order.rendered=function(){
// this.data == vendor object returned in parent helper
console.log(this.data);
};
You can also register a global helper, eliminating the need for an encapsulating parent template :
Handlebars.registerHelper("vendor",function(){
return{
name:"Chanel",
address:"Paris"
};
});
Template.order.rendered = function () {
console.log(Template.order.vendor());
}
