If you have multiple cache backends, django.core.cache.cache.clear() will only clear the default cache. To make sure your clear_cache command clears cache from all your backends, you should use the following command:

from django.conf import settings
from django.core.cache import caches

from django.core.management.base import BaseCommand

class Command(BaseCommand):
    help = "Clear cache"

    def handle(self, **options):
        for k in settings.CACHES.keys():
            caches[k].clear()
            self.stdout.write("Cleared cache '{}'.\n".format(k))
