Usage

Optional Configuration

Add twittercard to your settings.py INSTALLED_APPS list
There are a few configuration options to twittercard that can be placed in an OPTIONAL dictionary called TWITTERCARD_CONFIG in settings.py. Refer to the Twitter Card Docs for help regarding card and content attribution.

TWITTERCARD_CONFIG = {
    'SITE': '@foo',
    'SITE_ID': 'foo',
    'CREATOR': '@bar',
    'CREATOR_ID': 'bar'
}

SITE: optional
@username for the website used in the card footer.
SITE_ID: optional
Same as SITE, but the website's Twitter user ID instead. Note that user ids never change, while @usernames can be changed by the user.
CREATOR: optional
@username for the content creator / author.
CREATOR_ID: optional
Same as twitter:creator, but the Twitter user's ID.

Loading Template Tags

Load the twittercard custom tags
Call the twittercard_summary or twittercard_photo tag, passing in the appropriate parameters

{% load twittercard %}
<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <title>Django TwitterCard Example</title>
        {% twittercard_summary title="Foo" description="Bar" %}
    </head>
    <body></body>
</html>

The result, including the use of the TWITTERCARD_CONFIG options defined above, would be:

<meta name="twitter:card" content="summary">
<meta name="twitter:site" content="@foo">
<meta name="twitter:site:id" content="foo">
<meta name="twitter:creator" content="@bar">
<meta name="twitter:creator:id" content="bar">
<meta name="twitter:url" content="http://url.tld/sub/">
<meta name="twitter:title" content="Foo"/>
<meta name="twitter:description" content="Bar">

Summary TwitterCard

The summary card can be used for many kinds of web content, from blog posts and news articles, to products and restaurants.

{% twittercard_summary site="" site_id="" creator="" creator_id="" url="" title="" description="" image="" %}

site: optional
@username for the website used in the card footer. Will default to TWITTERCARD_CONFIG if supplied.
site_id: optional
Same as site, but the website's Twitter user ID instead. Note that user ids never change, while @usernames can be changed by the user. Will default to TWITTERCARD_CONFIG if supplied.
creator: optional
@username for the content creator / author.
creator_id: optional
Same as twitter:creator, but the Twitter user's ID.
url: required if not in OpenGraph
Will fallback to OpenGraph url if available. Will default to the current page URL. Canonical URL of the card content.
title: required if not in OpenGraph
Will fallback to OpenGraph title if available. Title should be concise and will be truncated at 70 characters.
description: required if not in OpenGraph
Will fallback to OpenGraph description if available. A description that concisely summarizes the content of the page, as appropriate for presentation within a Tweet. Do not re-use the title text as the description, or use this field to describe the general services provided by the website. Description text will be truncated at the word to 200 characters.
image: optional
Will fallback to OpenGraph image if available. URL to a unique image representing the content of the page. Do not use a generic image such as your website logo, author photo, or other image that spans multiple pages. Images larger than 120x120px will be resized and cropped square based on longest dimension. Images smaller than 60x60px will not be shown.

Photo TwitterCard

The photo card puts the image front and center in the Tweet.

{% twittercard_photo site="" site_id="" creator="" creator_id="" title="" description="" image="" image_width="" image_height="" %}

site: optional
@username for the website used in the card footer. Will default to TWITTERCARD_CONFIG if supplied.
site_id: optional
Same as site, but the website's Twitter user ID instead. Note that user ids never change, while @usernames can be changed by the user. Will default to TWITTERCARD_CONFIG if supplied.
creator: optional
@username for the content creator / author.
creator_id: optional
Same as twitter:creator, but the Twitter user's ID.
title: optional
Will fallback to OpenGraph title if available. See full explanation of title in the Summary Card.
description: optional
Will fallback to OpenGraph description if available. See full explanation of description in the Summary Card.
image: required if not in OpenGraph
Will fallback to OpenGraph image if available. A URL to the image representing the content.
image_width: optional
Will fallback to OpenGraph image width if available. Providing width in px helps us more accurately preserve the the aspect ratio of the image when resizing.
image_height: optional
Will fallback to OpenGraph image height if available. Providing height in px helps us more accurately preserve the the aspect ratio of the image when resizing.

Player TwitterCard

Currently not supported in django-twittercard. The player card is for interactive media experiences like videos, music players, and live streaming events.

NOTE: If any required fields are omitted, the card may not be shown in the Tweet.
