Roan 0.1

Django per-model cache purging
Roan is a per-model url purging Django app that connects to model signals and purge URLs wherever a model is saved, updated or deleted.

nginx proxy_cache support

Since Roan is based on a personal needing, it's based on nginx's proxy_cache.

Suppose you have the following purge mapping:

location ~ /purge(/.*) {
 allow 127.0.0.1;
 allow 74.207.234.182;
 deny all;
 proxy_cache_purge fscom "$scheme://$host$1";
}


Now suppose you have the following Django model:

class Post(models.Model):
 title = models.CharField(max_length=100)
 content = models.TextField()


And you have a URL /posts where users can see a list of posts. How can you set a forever cache and expect the cache to be refreshed whenever a new post is saved? Or whenever a post gets updated or deleted?

Using Roan you'll be able to connect one or more models to one or more URL. So you can connect the Post model with the /posts URL, and whenever a Post gets saved, updated or deleted, Roan makes an asynchronous request to the /purge/posts URL.
