I'm trying to get the super() macro to work.

rustc 1.70.0 (90c541806 2023-05-31)

Cargo.toml

[dependencies]
askama = {version = "0.11.1"}

page.html

{% extends "base.html" %}

{% block content %}
child
{{super()}}
{% endblock %}

base.html

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<meta http-equiv="X-UA-Compatible" content="IE=edge">
	<meta name="viewport" content="width=device-width, initial-scale=1.0">
	<title>Document</title>
</head>
<body>
{% block content %}
parent
{% endblock %}
</body>
</html>

main.rs

use askama::Template;

#[derive(Template)]
#[template(path="page.html")]
struct Page {}

fn main() {
	println!("{}", Page{}.render().unwrap());
}

The error:

error[E0609]: no field `super` on type `&Page`
 --> src\main.rs:3:10
  |
3 | #[derive(Template)]
  |          ^^^^^^^^ unknown field
  |
  = note: this error originates in the derive macro `Template` (in Nightly builds, run with -Z macro-backtrace for more info)

I've tried with { super() }, {{ super }}and {% super() %} but those don't work either. I haven't managed to find a working example on the internet...

Use {% call super() %}

Thank you, closing this issue, but perhaps an example should be put in the docs since it is different enough from the standard jinja2 syntax.

@reportingissue if you are able to submit a PR to the docs where you'd have found it, that would be great!
