Does Django invalidate query cache on update?

Question

I have enabled basic Django query caching by adding the following to my settings.py :-

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.db.DatabaseCache',
        'LOCATION': 'trialrun_cache_table'
    }
}

Does Django automatically invalidate query cache for a particular table if data is inserted or updated? If not, How should I go about implementing this behavior?

I think you've misunderstood what the DatabaseCache is. It is not a cache of your database, it's a cache in your database; that is, when you explicitly cache something, it'll be stored in a table in your db. It's still up to you to actually do any caching, and similarly it's up to you to do any cache invalidation.
