function-cache 0.2.0

A Django-based convenience decorator for caching results of functions to various backends.

Django Function Cache

Cache the results of a function on S3 (and more!). The function_cache decorator enables flexibility in how cache key is generated.

Example

In your settings.py, you can set up the FUNCTION_CACHE_BACKENDS (defaults to S3FunctionCacheBackend):

# Django Function Cache
# ---------------------
FUNCTION_CACHE_BACKENDS = {
    'default': {
        'BACKEND': 'function_cache.backends.S3FunctionCacheBackend',
        'OPTIONS': {},
    }
}

In your code, you can simply use the function_cache decorator

from django.contrib.staticfiles.storage import staticfiles_storage
from function_cache.decorators import function_cache


@function_cache(name='default', keys=('args[0]', 'args[1]', 'k'), storage=staticfiles_storage)
def create_dict(a, b, k=None, _cache_key=None):
    print(f'The cache key is <{_cache_key}>.')
    return dict(a=a, b=b, k=k)
#end def


def run():
    x = create_dict('variable a', 'b', k={'keyword argument': 42})
#end def
