Django default cache

Question

I'm importing and using cache as this:

from django.core.cache import cache
cache.add('a','b',60)

I haven't defined any settings for the cache in settings.py ,then where does this cache come from and where is it stored.

Django documentation says: "This object is equivalent to caches['default']", but what is the default ?

Answer 1

In https://docs.djangoproject.com/en/stable/topics/cache/#local-memory-caching says:

Local-memory caching

This is the default cache if another is not specified in your settings file

To add on to this, local memory caching is per process. So, this cache wont work for all the instances of your application. Only for the current one. – Inset

Empirically

>>> from django.conf import settings
>>> settings.CACHES
{'default': {'BACKEND': 'django.core.cache.backends.locmem.LocMemCache'}}

Answer 3

By default, Local-memory caching is used which is one of django caches.

So, because Local-memory caching is default, you don't need to write the code for Local-memory caching to "settings.py" as shown below unless you use multiple local memory caches:

# "settings.py"

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
        'LOCATION': 'unique-snowflake',
    }
}
