django-snakeoil
===============
django-snakeoil helps manage your ``<meta>`` tags. It works on all supported
Django versions and databases.
It offers full internationalization support (tags for multiple languages),
content set dynamically from object attributes, automatic Opengraph image
width and heights for ``ImageField``, and more.
`Full documentation <https://django-snakeoil.readthedocs.io/en/latest/index.html>`_
Getting started
===============
To install, ``pip install django-snakeoil`` or use your favourite package
manager.
You can use Snakeoil in two ways. If you'd like to attach metadata to an
object, you can use the model abstract base class:
.. code-block:: python
from snakeoil.models import SEOModel
class Article(SEOModel):
title = models.CharField(max_length=200)
author = models.ForeignKey(User, on_delete=models.CASCADE)
main_image = models.Imagefield(blank=True, null=True)
@property
def author_name(self):
return
@property
def snakeoil_metadata(self):
metadata = {
"default": [
{
"name": "author",
"content": self.author.get_full_name(),
},
{"property": "og:title", "content": self.title},
]
}
if self.main_image:
metadata["default"].append(
{"property": "og:image", "attribute": "main_image"}
)
return metadata
You can also override these tags in the admin per-object.
For situations where you can't change the model (flatpages, third party apps)
or don't have one at all, there is an ``SEOPath`` model that maps paths to
your meta tags.
Tags are added in the admin (or however else you like) as JSON. For example:
.. code-block:: JSON
{
"default": [
{"name": "description", "property": "og:description", "content": "Meta description"},
{"property": "og:title", "content": "My blog post"},
{"name": "author", "attribute": "author_name"},
{"property": "og:image", "static": "img/default.jpg"}
]
}
Where ``default`` will work for any language. You can replace ``default``
with a language code, e.g. "nl_NL", and these tags will only display if the
current language is Dutch. This will generate something like:
.. code-block:: html
<meta name="description" property="og:description" content="Meta description">
<meta property="og:title" "content="My blog post">
<!-- from my_object.author_name -->
<meta name="author" content="Tom Carrick">
<!-- build a static URL -->
<meta property="og:image" content="/static/img/default.jpg">
Note that when using ``static``, width and height are not added, but you may
add these yourself. For ``ImageField``, this will be added automatically:
.. code-block:: JSON
{
"default": [
{"property": "og:image", "attribute": "main_image"}
]
}
Results in:
.. code-block:: html
<meta property="og:image" content="/media/blog_1_main_image.jpg">
<meta property="og:image:width" content="640">
<meta property="og:image:height" content="480">
Django Templates
----------------
Add ``snakeoil`` to your ``INSTALLED_APPS``:
.. code-block:: python
INSTALLED_APPS = [
"snakeoil",
# ...
]
In your base template, add this where you want the tags to appear:
.. code-block:: html
{% load snakeoil %}
{% block head %}
{% meta %}
{% endblock %}
This will automatically find an object based on the ``get_absolute_url()``
of your model, by looking in the request context. If nothing is found,
snakeoil will check for an ``SEOPath`` object for the current path. If
you have an object, it is recommended to pass it into the tag directly
to short-circuit the tag finding mechanisms:
.. code-block:: html
{% meta my_obj %}
Jinja2
------
Set your environment:
.. code-block:: python
from jinja2 import Environment
from snakeoil.jinja2 import get_meta_tags
def environment(**options):
env = Environment(**options)
env.globals.update(
{
"get_meta_tags": get_meta_tags,
# ...
}
)
return env
In your template:
.. code-block:: html
{% block meta %}
{% with meta_tags=get_meta_tags() %}
{% include "snakeoil/seo.jinja2" %}
{% endwith %}
{% endblock meta %}
To pass in an object:
.. code-block:: html
{% block meta %}
{% with meta_tags=get_meta_tags(my_object) %}
{% include "snakeoil/seo.jinja2" %}
{% endwith %}
{% endblock meta %}
Notes
=====
Thanks to kezabelle for the name. For those wondering:
Metadata is often used for SEO purposes. A lot of people (rightly or not)
consider SEO to be snakeoil. Also, SnakEOil. Very clever, I know.
The old version of django-snakeoil can be found on the ``old`` branch, but
won't be updated.
