django-akamai 1.0.1

Using Signals

signals.py defines two signals, one that initiates a purge request directly, and another that queues the request. The queueing signal is conditionally defined and depends on the successful import of PurgeRequestTask, which depends on django-celery being installed.

When sending these signals from other apps, you can pass in a variety of things as the sender for convenience. Sender can be a single URL string, a list of URL strings, an individual Django object, or a QuerySet. If passing in an object or QuerySet, then get_absolute_url() must be defined on every object.

Example of signalling to immediately perform the request:

>>> from akamai.signals import purge_request, queue_purge_request
>>> obj = MyObject.objects.get(pk=3)
>>> obj.get_absolute_url()
u'http://www.example.com/blahblah.html'
>>> purge_request.send(obj)

Or, to queue the request using Celery:

>>> queue_purge_request.send(obj)

Using Tasks

To use the task directly, import PurgeRequestTask from tasks.py thusly:

>>> from akamai.tasks import PurgeRequestTask
>>> obj = MyObject.objects.get(pk=3)
>>> result = PurgeRequestTask.delay(obj)
>>> print result

Using PurgeRequest directly

You may also import PurgeRequest from purge.py and use it directly. Not that only 200 urls will be sent with each purge request, due to limits set by Akamai. If you add more than 200 urls, purge() will need to be called until none remain. Calling purge_all() will issue as many requests as needed for the full list, possibly taking a significant amount of time before returning.

If you don’t provide a username and password when creating the PurgeRequest object, then your project’s settings.py will be checked for AKAMAI_CCUAPI_USERNAME and AKAMAI_CCUAPI_PASSWORD. Failure to provide login info via either mechanism results in a NoAkamaiUsernameProvidedException and/or NoAkamaiPasswordProvidedException.

Example:

>>> pr = PurgeRequest(username="ccuapi_user", password="1234567")
>>> pr.add("http://www.example.com/url-1.html")
>>> pr.add(u"http://www.example.com/url-2.html")
>>> req = pr.purge()
>>> print pr.last_result
(PurgeResult){
   resultCode = 100
   resultMsg = "Success."
   sessionID = "987654321"
   estTime = 420
   uriIndex = -1
   modifiers[] = <empty>
 }
>>> print pr.urls
