Sometimes, for clarity, an included template contains code for different
parts of the parent.
This patch allows an extra {{{block}}} optional argument to the include
tag. If specified, only that particular block of the included template
will be included.
an example:
base.html:
{{{
<head>
{% include "table-include" "jscript" %}
</head>
<body>
<table>
{% include "table-include" "header" %}
{% for row in rows %}
{% include "table-include" "rowdata" %}
{% endfor %}
</table>
</body>
}}}
table-include.html:
{{{
{% block jscript %}
<script> <!- --> </script>
{% endblock %}
{% block header %}
<tr><th>heading</th></tr>
{% endblock %}
{% block rowdata %}
<tr><td>{{row.data}}</td></tr>
{% endblock %}
}}}
Without this patch you would need three different included tepmlates like:
table-include-js.html, table-include-header.html and table-include-
rowdata.html making the whole thing less maintainable
if the block in arg is not found maybe we should raise a
{{{TemplateSyntaxError}}} (or maybe not)
patch is just a proof of concept. Tests included
