Blocks are only definable at a template’s top level. If you extend a template, any values set in the child template using a set
tag will be accessible from the template it is extending. For example, if you have a template named layout.html
:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
<title>{{ title }} | Site.com</title>
....
{% block content %}{% endblock content %}
....
</html>
And you have this child template, index.html
:
{% extends "layout.html" %}
{% set title = 'Homepage' %}
{% block content %}
(html code here)
{% endblock content %}
Then the reference to title
in the parent would resolve to 'Homepage'
. You can do this with any type of variable. For what you’re doing, I don’t think there is any need for macros – if you take advantage of this feature and place blocks well, you will be able to do pretty much everything you need to do as far as layouts are concerned. I would look at some of the templates used by Plurk Solace, which is written by one of the Jinja2 authors, if you want to get a good idea of when to use various features of Jinja2.
