How to add multiple types of cache in CACHES setting in settings.py is django

Question

I have a django application. I want to use both database cache and redis cache at different places in my application. How do I write the settings in settings.py?

How do I import both redis and database cache in my code and set some data into both types of cache?

I tried this in django settings.py

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

 'Redis': {    
    'BACKEND': 'django.core.cache.backends.redis.RedisCache',
    'LOCATION': 'redis://127.0.0.1:6379',
    'OPTIONS': {
        'db': '1',
        'parser_class': 'redis.connection.PythonParser',
        'pool_class': 'redis.BlockingConnectionPool',
     } 
   }
 }

but when I import in my code from django.core.cache import cache It always picks the default one. How do I import database cache in one python file and redis cache in a different python file?

You need to give your cache name in the cache module while saving and getting the data from the second cache. like this in your case:

from django.core.cache import cache
redis_cache = caches['Redis']
redis_cache.get('key')
