Using tags with {{ block.super }}
It seems {% style "some/style.css" %} tags don't render within {{ block.super }} calls, while explicit <link ... /> tags render as expected within a {{ block.super }} call.
For example, here's a cascading a->b->c hierarchy, each which includes 2 stylesheets in the block head: one named "*-style.css" rendered with a {% style ... %} tag, and the other "*-link.css" rendered with an explicit <link ... /> tag.
The final child, c, is the only one which renders a link from the "*-style.css" tag. The parents do not, even though each child calls {{ block.super }}. However, the explicit <link ... /> tags are rendered by the {{ block.super }} calls.
a.html
<!DOCTYPE html>
<html lang="en">
<head>
{% block head %}
{% style "a-style.css" %}
<link href="a-link.css" rel="stylesheet" />
{% endblock %}
</head>
<body></body>
</html>
b.html
{% extends "a.html" %}
{% block head %}
{{ block.super }}
{% style "b-style.css" %}
<link href="b-link.css" rel="stylesheet" />
{% endblock %}
c.html
{% extends "b.html" %}
{% block head %}
{{ block.super }}
{% style "c-style.css" %}
<link href="c-link.css" rel="stylesheet" />
{% endblock %}
I just ran this in a repl for a quick test, here's the output:
user=> (println (selmer.parser/render-file "c.html" {}))
<!DOCTYPE html>
<html lang="en">
<head>
<link href="a-link.css" rel="stylesheet" />
<link href="b-link.css" rel="stylesheet" />
<link href="c-style.css" rel="stylesheet" type="text/css" />
<link href="c-link.css" rel="stylesheet" />
</head>
<body></body>
</html>
Is it intended that style tags do not render within {{ block.super }}? If so, is it an intentional behavior that applies to other tags as well? I've only tested with style so far.
I also dumped a minimal repro here.
After testing a few other cases, this applies to the style and include tags as well. Are tags intentionally unsupported via {{ block.super }}?
Hi,
It's been a little while, I'll have to take a look at the specifics, but I suspect it's due to the fact that tags get run at compile time, while block.super operates at runtime on the compiled template.
Hi,
I confirm, it seems like tags in parent's block are ignored if called with {{block.super}}.
