django-pingback
=================
This two applications provide 3 connected services: pingback server,
pingback client and directory ping client.
Depends on the `django-xmlrpc`_.
Configuration
-------------
First, install the `django-xmlrpc`_ application. You can download it
either from `repo`_ or just use setuptools::
easy_install -Z -f http://pypi.aartemenko.com django-xmlrpc
Next, download and install ``django-pingback``:
* download sources from main `repository`_
* or use ``easy_install django-pingback``
* add ``pingback`` to your ``INSTALLED_APPS``
* run ``./manage.py syncdb``
* setup client and server callbacks.

.. _repository: django-pingback_
Connecting server
-----------------
Pingback server receives pings from other sites, so, we must create
function which binds our URLs an objects.
But first of all, add this urlpattern to your urls configuration::
((r'^xmlrpc/$', 'django_xmlrpc.views.handle_xmlrpc', {}, 'xmlrpc'))
It is a handler for all xmlrpc requests.
Usually, blog has a detailed view for each post. Suppose that our view
resides in ``blog.views.post_detail`` and accepts one keyword arguments ``slug``.
Here is simple example, how to make ``Post`` objects pingable::
from datetime import time, date, datetime
from time import strptime
from blog.models import Post
from pingback import register_pingback, ping_func
from django_xmlrpc import xmlrpcdispatcher
# create simple function which returns Post object and accepts
# exactly same arguments as 'details' view.
def pingback_blog_handler(slug, **kwargs):
return Post.objects.get(slug=slug)
# register pingback on our post_detail
register_pingback('blog.views.post_detail', pingback_blog_handler)
# register pingback handler in the dispatcher
xmlrpcdispatcher.register_function(ping_func, 'pingback.ping')
.. note::
If you are using middleware (described later), you don't need to register
ping_func in xmlrpc dispatcher, it's done automatically.
Now, go at you http://mysweetsite.com/xmlrpc/ and you should see
``pingback.ping`` method among few other system methods. If it is not
there, then you made mistake in you server setup.
Also, you need to tell other sites, that your blog accepts
pingbacks. You can do it by adding a link in the head of your site::
<link rel="pingback" href="{% url 'xmlrpc' %}" />
Or by adding X-Pingback HTTP header. Do do this, just add such line in
the ``settings.py``::
MIDDLEWARE_CLASSES = [
# ...
'pingback.middleware.PingbackMiddleware',
]
Connecting client signals
-------------------------
Let's suppose, that you have a blog and want to ping external sites
(like Technorati) on post save, and to receive pingbacks from other
sites. Next two sections contain simple 'how-to' enable these features.
At first, setup configuration in the settings, here is an example::
DIRECTORY_URLS = (
'http://ping.blogs.yandex.ru/RPC2',
'http://rpc.technorati.com/rpc/ping',
)
Next, you must connect some signals to ping workers, which created using
``ping_external_links`` and ``ping_directories`` functions::
from django.db.models import signals
from pingback.client import ping_external_links, ping_directories
from blog.models import Post
signals.post_save.connect(
ping_external_links(content_attr = 'html',
url_attr = 'get_absolute_url'),
sender=Post, weak=False)
signals.post_save.connect(
ping_directories(url_attr = 'get_absolute_url'),
sender=Post, weak=False)
Please note, that in the ``content_attr`` you must give either attribute
or method name, which returns HTML content of the object.
If you don't have such attribute or method, for example if you apply
markdown filter in the template, then ``content_func`` argument can be
used instead of the ``content_attr``.
``content_func`` must return HTML, and must accepts an instance as a
single argument.
.. note::
Pay attention to the ``weak=False`` argument. If case of omitting Django event
dispatcher will remove your signal.
Template tags
-------------
To show pingbacks on your page, you can use code like this::
{% load pingback_tags %}
{% get_pingback_list for object as pingbacks %}
{% if pingbacks %}
<h1>Pingbacks</h1>
{% for pingback in pingbacks %}
<div class="b-pingback">
<p class="b-meta">
<a name="pingback-{{ pingback.id }}"
href="{{ object.get_absolute_url }}#pingback-{{ pingback.id }}"
class="b-permlink">permalink</a>
{{ pingback.date }}, pingback from {{ pingback.url|urlizetrunc:40 }}:
</p>
<p>{{ pingback.content }}</p>
</div>
{% endfor %}
{% endif %}
Also you can use ``{% get_pingback_count for object as cnt %}``, to save
pingbacks' count in the context variable.
