Updated with sqlalchemy 2.0 syntax (using 1.4 with future)

[doylejg]

I was using this example for a class and I wanted to use the newer syntax. I have a version that doesn't use the with .. : syntax if you prefer.

Let me know if you're interested in the other version. I tried to use realistic SQLAlchemy - Flask packaging paradigm without actually using multiple files. I also chose not to use the with syntax.

Here is a snippet

SessionLocal = sessionmaker(autocommit=False, autoflush=False, bind=engine)
app.session = scoped_session(SessionLocal)

...

@app.route("/")
def home():
    todo_list = app.session.execute(select(Todo)).scalars().all()
    return render_template("base.html", todo_list=todo_list)
