django-capture-tag
A micro-library to capture output in Django templates.
This can be useful for example to:
Repeat page titles in web pages, e.g. for the <title> tag and breadcrumb.
Repeat contents for Social Media tags.
Reusing thumbnail output in multiple places.
Fetch configuration data from extended templates.
Installation
Install the module from PyPI:
pip install django-capture-tagAdd the package to INSTALLED_APPS:
INSTALLED_APPS += (
'capture_tag',
)Load the tag in your template:
{% load capture_tags %}Syntax
The following options are available:
{% capture %}...{% endcapture %} # output in {{ capture }}
{% capture silent %}...{% endcapture %} # output in {{ capture }} only
{% capture as varname %}...{% endcapture %} # output in {{ varname }}
{% capture as varname silent %}...{% endcapture %} # output in {{ varname }} onlyExample usage
To capture Social Media tags:
{% load capture_tags %}
<head>
...
{# Allow templates to override the page title/description #}
<meta name="description" content="{% capture as meta_description %}{% block meta-description %}{% endblock %}{% endcapture %}" />
<title>{% capture as meta_title %}{% block meta-title %}Untitled{% endblock %}{% endcapture %}</title>
{# display the same value as default, but allow templates to override it. #}
<meta property="og:description" content="{% block og-description %}{{ meta_description }}{% endblock %}" />
<meta name="twitter:title" content="{% block twitter-title %}{{ meta_title }}{% endblock %}" />
</head>Take configuration from extended templates:
# base.html
{% load capture_tags %}
# read once
{% capture as home_url silent %}{% block home_url %}{% url 'app:index' %}{% endblock %}{% endcapture %}
# reuse twice.
<a href="{{ home_url }}" class="btn page-top">Back to home</a>
<a href="{{ home_url }}" class="btn page-bottom">Back to home</a>
# child.html
{% extends "base.html" %}
{% block home_url %}{% url 'user:profile' %}{% endblock %}Notice
When a value is used only once, this package is not needed. In such case, simply place the {% block .. %} at the proper location where contents is replaced. All common Django template tags support the as variable syntax, such as {% url 'app:index' as home_url %} or {% trans "Foo" as foo_label %}.
