How to remove value from cache in Django?

Question

Django

Tell me how to remove the value from the cache when updating. The REST API caches a list of rarely changed reference. But he is still changing. At the time of creating a new entry or deleting, you need to update the existing cache keys. Faced with a similar problem?

REST API on DRF.

Answer 1

If the data in the database is changed only through the Django application, then the easiest way is to hang up the handler on the signal to save / delete the model and clear the cache.
