Partials with parameters

[karlhorky]

Can you support the handlebars.js partial parameters notation? Like in the spec here?

context

{
  "title": "profile",
  "dudes": [
    {
      "name": "Yehuda",
      "url": "http://yehuda"
    },
    {
      "name": "Alan",
      "url": "http://alan"
    }
  ]
}

index.hbs

<ul>
  {{#each dudes}}
    {{> dude title=../title class="list-item"}}
  {{/each}}
</ul>

dude.hbs

<li class="{{class}}">
  {{title}}: <a href="{{url}}">{{name}}</a>
</li>

expected output

<ul>
  <li class="list-item">
    profile: <a href="http://yehuda">Yehuda</a>
  </li>
  <li class="list-item">
    profile: <a href="http://alan">Alan</a>
  </li>
</ul>

I saw the #partial and #block helpers here, but I'm working on a project where we would like to keep parity with handlebars.js if possible.

Seems this card needs to be merged with #349

@husayt These partials were actually implemented in v2.0.0. So this is a bit older than v3.0.0 as in the other issue.

Has this been implemented? This feature is pretty useful.
Problem is, if you have an #each loop with a child partial in it, the child can't access properties of the parent scope. But if this feature is implemented, then the parent can specify those parameters on each child partial declaration.

Could this be the culprit?
Says it's using "/handlebars-v1.3.0.js"

Thanks @jknack!

HI,
I am using the version 2.2.2 together with handlebars-v2.0, and I cannot get this parameter and partial thing working.

I have a very simple use case where:

{{> mypartial label="Value of the label" }}

mypartial.hbs.html
{{label}}

And it is not working. Do you see any problem with it? Also, can someone show me a working example?
Thank you.

[jknack]

did you see any error? there are a few unit tests that demonstrate partials param in action. Here is one: https://github.com/jknack/handlebars.java/blob/master/handlebars/src/test/java/com/github/jknack/handlebars/i350/Issue350.java

Partial parameters require the MapValueResolver.INSTANCE to be registered as resolver in the context. If partial parameters are not passed, this might be the reason.
