Hallöchen!
I'd like to clean up the cache when an updated model instance is
saved to the database backend.
Let's assume that I have a model "Person", and the user can view the
person's information on a webpage. However, much data must be
collected for this webpage, so it's a costly operation and should be
cached.
No problem, because I can generate a cache key containing the
person's primary key, the timestamp, and the user's settings
(e.g. language) and save the collected data into the cache.
Now some of this collected data changes. How can I delete all cache
keys that have become invalid by this? I could store all keys in a
CharField in the Person model and use signals. Is there a better
approach?
Tschö,
Torsten.
