Update: this works, but it is fragile (someone could change the parent template and break the child template without realizing it):

// parent template
<% for(var i = 0; i < children.length; ++i) { %>
    {#child child-report}
<% } %>

// child template
<h2><%= children[i].Name %></h2>

This option also works in a similarly fragile, but slightly better, way:

// parent
<% for(var i = 0; i < children.length; ++i) { %>
    <% const me = children[i] %>
    {#child child-report}
<% } %>

// child
<h2><%= me.Name %></h2>

It would still be nice to be able to somehow reassign this so that the child template will scope as expected.

I have noticed that with handlebars you can do the following:

// In parent report (engine = handlebars, recipe = phantom-pdf)
<h1>{{title}}</h1>
{{#each children}}
  {#child child-report}
{{/each}}

// In child report (engine = none, recipe = html)
<h2>{{Name}} (age {{Age}})</h2>

But there does not seem to be an 'each' equivalent for EJS. I've tried this, as per the EJS help page on the jsreport site:

// parent (engine = ejs, recipe = phantom-pdf)
<h1><%= title %></h1>
<% for(var i = 0; i < children.length; ++i) { %>
  {#child child-report}
<% } %>

// child (engine = none, recipe = html)
<h2><%= Name %> (age <%= Age %>)</h2>

But age and name are obviously undefined, because I am not using the child in children[i].

To pass in children[i], I've tried this, which fails to parse:

{#child child-report @data=children[i]}

I've also tried this, which did not work because it defined self, but self.Name was undefined in the child template.

{#child child-report @data.self=children[i]}

As a last attempt, I tried this, which did not work (this is defined, but not this.Name or Name on its own):

{#child child-report @data.this=children[i]}

Is there a special @data trick that I am missing, or does the child template functionality require additional code to work with EJS?

We have a lot of existing templates in EJS so it would be great to keep using them with jsreport.

Thanks in advance!
