Passing Nested Data Parameters to Partials

[ldrummond]

Hello!
I have a question that I am bringing here only because I couldn't find documentation or other references to this.
Is it possible to overwrite a nested data parameter for a partial ( {{> partial user.name='Laura'}})? Or is this something that requires a helper?
Js Fiddle example

Code that fails to compile

var data = {
  "user": {
    "name": "Bob"
  }
}

Handlebars.registerPartial("user_partial", "{{user.name}}"); 

// Overwrite the "user.name" parameter when rendering the partial
var template = Handlebars.compile(
  "My name is {{> user_partial user[name]='Laura'}}"  // throws compiler error
); 
document.getElementById('output').innerHTML = template(data);

Desired output

My name is Laura

Thanks

You can use Partial Contexts for achieving this: https://handlebarsjs.com/guide/partials.html#partial-contexts

My name is {{user.name}}

My name is {{> user_partial overrideContext}}

{
  "user": {
    "name": "Bob"
  },
  "overrideContext": {
    "user": {
      "name": "Bobby"
    }
  }
}
