Changing Scope Edit Page

Sometimes you may want to invoke a section of your template with a different context.

For example, instead of repeating a long path, like in this example:

1

Welcome back, <b>{{person.firstName}} {{person.lastName}}</b>!

We can use the {{#with}} helper to clean it up:

1
2
3

{{#with person}}
  Welcome back, <b>{{firstName}} {{lastName}}</b>!
{{/with}}

{{#with}} changes the context of the block you pass to it. The context, by default, is the template's controller. By using the {{#with}} helper, you can change the context of all of the Handlebars expressions contained inside the block.

Note: it's possible to store the context within a variable for nested usage using the "as" keyword:

1
2
3
4
5

{{#with person as user}}
  {{#each book in books}}
    {{user.firstName}} has read {{book.name}}!
  {{/each}}
{{/with}}
