Re: [flask] Using Flask-Cache and register_module together

Use an application factory as described in

http://flask.pocoo.org/docs/patterns/appfactories/

Create a separate file (such as modules.py) and put

from flaskext.cache import Cache
cache = Cache()

And then from the appfactory

from modules import cache

def init_app():
   ....
   cache.init_app(app)
   ....
   return app

When you need to use memoize on any function, just import the cache object
from the modules.py
