How can I implement caching in Flask with ORM?

You can use Flask-Caching along with SQLAlchemy to cache your ORM queries. Would you like a code example?

Yes, please provide a code example.

Sure! First, install Flask-Caching. Then, you can set it up like this:

from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_caching import Cache

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///example.db'
app.config['CACHE_TYPE'] = 'simple'

db = SQLAlchemy(app)
cache = Cache(app)

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(50))

@cache.cached(timeout=60)
def get_users():
    return User.query.all()

This caches the result of get_users() for 60 seconds.

What if I want to cache specific queries instead of the whole function?

You can use the @cache.memoize() decorator to cache specific queries. For example:

@cache.memoize(timeout=60)
def get_user_by_id(user_id):
    return User.query.get(user_id)

This caches the result of get_user_by_id() for each unique user_id.
