Django 1.5 does not have a utility method to delete template fragment cache, with arguments.
In order to achieve this, you must create a custom method:
|
1 2 3 4 5 6 7 8 9 10 11 |
from django.core.cache import cache from django.utils.hashcompat import md5_constructor from django.utils.http import urlquote def invalidate_template_fragment(fragment_name, *variables): args = md5_constructor(u':'.join([urlquote(var) for var in variables])) cache_key = 'template.cache.{0}.{1}'.format(fragment_name, args.hexdigest()) cache.delete(cache_key) |
Example usage:
|
1 2 3 4 5 6 7 |
{% cache 259200 key_name model_instance.pk %} ... cached content here ... {% endcache %} // note that "model_instance.pk" is optional argument. You can use as many as you need |
… and delete the cache:
|
1 2 3 |
invalidate_template_fragment('key_name', model_instance.pk) |
In django 1.6+ you can do this more easy:
|
1 2 3 4 5 6 7 |
from django.core.cache import cache from django.core.cache.utils import make_template_fragment_key key = make_template_fragment_key('key_name', [model_instance.pk]) cache.delete(key) |
