问题 I am using cache.memoize to memoize a function with Flask-Cache. How can I get the cache key which got set in the decorated function? How can I test that the function is cached during testing? from flask import Flask from flask.ext.cache import Cache app = Flask(__name__) cache = Cache(app, config={'CACHE_TYPE': 'simple'}) @cache.memoize(timeout=10) def get_news(nid, lang=None): return nid, lang @app.route('/news/<str:nid>') def news(news_id): return 'News: ' + get_news(news_id) 回答1: When

问题 Right now, I am working on Airbnb Superset project for working purpose. I know Superset supports cache (by Flask-Cache), but I got stuck when I set up the configuration. My config.py file looks like this: CACHE_DEFAULT_TIMEOUT = 60 * 60 * 24 CACHE_CONFIG = {'CACHE_TYPE': 'filesystem', 'CACHE_DIR': os.path.join(BASE_DIR, '/temp'), 'CACHE_DEFAULT_TIMEOUT': CACHE_DEFAULT_TIMEOUT, } But after I re-start the server, there is no different. Does anyone know how to set up? Thanks. 回答1: I have set up

问题 In the following snippet I have the usual Flask app calling a function from another python module (also below). I would like a (slow/expensive/arbitrary) function to be cached in memory using (say) Flask-Cache, so that its data are available between requests. I thought the data themselves were static, but I think the fact that they are OpenCV keypoint-detector objects (e.g. SIFT, SURF, ORB etc.) means that their addresses are changing between requests - and it's these objects that are

问题 I made a change on one of the .js files that I use and no matter what I do, flask insists on picking up, from memory cache, the last version of the file, without the change. To clarify, I have the following structure. It all starts with foo.html return render_template foo.html foo.html has a form inside that calls flask with some data and then returns a second template bar.html : return render_template bar.html This second template calls some .js file, placed in the static folder, but it

问题 I had this. @login_manager.user_loader def load_user(id=None): return User.query.get(id) It was working fine until I introduced Flask-Principal. @identity_loaded.connect_via(app) def on_identity_loaded(sender, identity): # Set the identity user object identity.user = current_user # return if hasattr(current_user, 'id'): identity.provides.add(UserNeed(current_user.id)) # Assuming the User model has a list of roles, update the # identity with the roles that the user provides if hasattr(current

问题 In the Flask-Cache documentation all the examples use a finite timeout. I'd like to never refresh the cache while the app is running. Is this possible, and if so how do I do it? 回答1: Flask-Cache uses werkzeug.contrib.cache behind the scenes. From the documentation it's made clear that A timeout of 0 indicates that the cache never expires. So yes, infinite caching is supported and can be turned on by setting the timeout to zero. 回答2: There does not seem to be anything listed in the docs. I
