Django Request Cache

Django Request Cache provides a cache for each request (within your Django Request/Response cycle).

Quick start

1. Download and install using pip install

pip install django-request-cache

2. Add UserForeignKeyMiddleware and RequestCacheMiddleware to your MIDDLEWARE settings like this:

MIDDLEWARE = (
    ...
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    ...
    'django_userforeignkey.middleware.UserForeignKeyMiddleware',
    'django_request_cache.middleware.RequestCacheMiddleware',
)

or if you are still using the an older Django version (e.g., Django 1.8) with MIDDLEWARE_CLASSES:

MIDDLEWARE_CLASSES = (
    ...
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    ...
    'django_userforeignkey.middleware.UserForeignKeyMiddleware',
    'django_request_cache.middleware.RequestCacheMiddleware',
)

3. Use the per-request cache as a decorator

from django_request_cache import cache_for_request

@cache_for_request
def do_some_complex_calculation(a, b, c):
    print("Calculating... please wait")
    return a * b * c

Try it out by executing do_some_complex_calculation multiple times within your request
