Jinja Layout

Easier layouts for Jinja templates.

Installation

pip install jinja-layout

Usage

The jinja_layout.LayoutExtension needs to be added to your environment:

from jinja2 import Environment, PackageLoader

env = Environment(loader=PackageLoader(__name__, 'templates'))
env.add_extension('jinja_layout.LayoutExtension')

Jinja-layout introduces the use_layout directive. There are two optional arguments:

• a template name to extend from (default: "layout.html")
• the name of the default block to override (default: "content")

You can change the default layout template using the defaut_layout attribute on your environment and the default block name using the default_layout_block attribute.

This directive is similar to Jinja's extends directive but does not require the use of blocks. The content which is not used in blocks, will be automatically wrapped in a block. The name of this block is defined by the second argument of the directive.

Example

Let's consider the following layout saved as layout.html:

<html>
  <head>{% block head %}{% endblock %}</head>
  <body>{% block content %}{% endblock %}</body>
</html>

Basic layout example:

{% use_layout %}
hello world

Overriding the header block:

{% use_layout %}
{% block head %}<title>example</title>{% endblock %}
hello world

Using blocks all the way:

{% use_layout %}
{% block head %}<title>example</title>{% endblock %}
{% block content %}hello world{% endblock %}
