javascript - Accessing parent helper in Meteor -

-

i find myself dividing work templates still use same helpers.

so, have template structure:

<template name="maintemplate">   <div>{{> firsttemplate}}</div>   <div>{{> secondtemplate}}</div>   <div>{{> thirdtemplate}}</div>   <div>{{> fourthtemplate}}</div> </template>

now each of these templates wants use same helper, let's call datahelper:

template.maintemplate.helpers({   datahelper: function() {     //do stuff     return result   } })

sadly, helper can't accessed in template first through fourth typing {{datahelper}} how events work.

my solution has been create global helper instead, seems tad overkill, since have few pages don't care these helpers @ all. solution create 4 separate helpers but, hey, dry.

am missing simple here?

there isn't obvious way in current version of meteor. 1 solution child template "inherit" helpers parent. can pretty using meteor-template-extension. here's example:

html

<body>   {{> parent}} </body>  <template name="parent">   <h1>parent</h1>   {{> child}} </template>  <template name="child">   <h2>child</h2>   <p>{{saysomething}}</p> </template>

js

template.parent.helpers({   saysomething: function() {     return random.choice(['hello', 'dude!', 'i know right?']);   } });  template.child.inheritshelpersfrom('parent');

the template child inherits of parent's helpers has direct access saysomething.

this technique has 2 drawbacks:

  • you have specify inheritshelpersfrom relationship
  • all of parent's helpers inherited
