If the parent is the enclosing component, and the child component is rendered through the parent’s {{yield}}
helper, then the child should have access to properties in the parent component via parentView
. There’s an outstanding proposal to rename this to parentComponent
for components.
Allow the parent template to wrap the child components:
<script type="text/x-handlebars" id="components/filter-options">
<h2>{{input type="checkbox" checked=hasSelectAll}} Filter Options</h2>
{{yield}}
</script>
Then make use of the templates like this:
{{#filter-options}}
{{filter-option ...}}
{{filter-option ...}}
{{/filter-options}}
And then in the child controller:
parentHasSelectAll: Ember.computed.oneWay('parentView.hasSelectAll')
