Access to root context in Handlebar.js template

Question

Is there any built-in method for accessing the root context in a Handlebars.js template? Most of the helpers are adding a nested context and you have to write ../ before the variable in that context to access it but that is not very practical if you have lots of eachs, ifs, etc.

Answer 1

Use @root. This is in handlebars-v2.0.0.js

{{@root.somthing.nested_somthing}}

Answer 2

there is no possibility to access root context of template once you change the context with looping (e.g. each) more info

However there is a possibility to access previous context with '../'

# app/assets/javascript/contents.coffee
body = HandlebarsTemplates['my_hbs_template']({
  view:{
    registryName: 'foo',
    data: {items: {x: 'x'}}
    }
  })

template:

<!-- app/assets/javascript/templates/my_content.hbs -->
<table class="table">
  <tbody>

  {{#each view.data.items}}
    <tr>
      <td>{{@key}}</td>
      <td>
        Hello from {{../view.registryName}}
      </td>
    </tr>
  {{/each}}
  </tbody>
</table>
