• django cache clear

CACHE_HOURS = 12
ITEM_VALID_HOURS = 6

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.db.DatabaseCache',
        'LOCATION': 'my_cache',
        # 'TIMEOUT': 604800,  # 7 days
        # 'TIMEOUT': 60 * 60 * 24,  # 1 day
        'TIMEOUT': 60 * 60 * CACHE_HOURS,  # 12 hours
        'OPTIONS': {
            'MAX_ENTRIES': 5000000,  # https://docs.djangoproject.com/en/1.11/topics/cache/#cache-arguments
        },
    }
}

Before using the database cache, you must create the cache table with this command:

python manage.py createcachetable

from django.conf import settings
from django.views.decorators.cache import cache_page

cache = cache_page(60 * 60 * settings.CACHE_HOURS)

path('image/similar', cache(ImageSimilarView.as_view()), name="image_similar"),
