cache.py
Use simple for page cache, memcached, redis, etc.
from flask_caching import Cache
cache = Cache(config={"CACHE_TYPE": "simple"})
__init__.py
Apply cache settings to app by doing cache.init_app (app)
from flask import Flask
from app.cache import cache
from app.views.about import about
from app.views.main import main
def get_app() -> Flask:
app = Flask(__name__)
cache.init_app(app)
_register_blueprint(app)
return app
def _register_blueprint(app: Flask) -> None:
app.register_blueprint(about)
app.register_blueprint(main)
sample.py
@ cache.cached (timeout = 50) By adding a decorator, the target page becomes a page cache.
from flask import Blueprint
from app.cache import cache
sample = Blueprint("sample", __name__)
@sample.route("/")
@cache.cached(timeout=50)
def index():
print("sample.index")
return "sample.index"
