Django-hpcloud is a helper module intended for use with django to hook into the HPCloud services.
You need to supply in your settings.py file:
- HP_SECRET_KEY
- HP_ACCESS_KEY
- HPCLOUD_USERNAME
- HPCLOUD_PASSWORD
- TENANT_ID
- OBJECT_STORE_URL
- REGION_URL
- CDN_URL
- HPCLOUD_TTL_MAP
Most of these can be found on your API Keys page. The HPCLOUD_TTL_MAP is a map between extension types and their "Time To Live" in seconds, which, when uploaded to the CDN is the number of seconds they will be cached for.
HPCLOUD_TTL_MAP = {
".css": "900",
".js": "1"
}This would make css files last for 900 seconds (15 minutes) in the cache and Javascript files for only a second (which means they will never be cached.)
Using the django-hpcloud module.
The primary benefit so far is being able to transparently access your CDN containers via template tags.
When the module is first loaded it queries the HPCloud endpoints for your CDN enabled containers. You can then create templates such as:
{% load hpcloud %}
<html>
<body><h3>Awesome Gallery</h3>
{% for pic in pictures %}
<img href="{% cdn container pic.name %}" />
{% endfor %}
</body>
</html>Also, from the command line this module provides a django command which helps you upload all your static files into the object store.
