    What is @app.route?
    Times asked 2
    Official solution

    Simple@app.route URL ko Python function se jodta hai. @ wala cheez decorator hai.

    @app.route('/hello/<name>', methods=['GET'])
    def hello(name):
        return f'Hello {name}'

    Decorator function ko wrap karke extra behaviour deta hai (route register, login_required).
    Endpoint generally function name. Path /hello/Ram.
    <int:id> type converter — sirf integer. Bina converter string. ID chahiye to int safer.
    methods=['POST'] only POST. Default GET.
    functools.wraps custom decorator mein original function name/docs preserve karta hai.

    I explained the whole app in detail in a single flow (including the models) and also explained the code (be it backend or frontend) along with the GUI for some important and complex features.
    Times asked 1
    Official solution

    Simplemodels.py = har table ki class: columns, PK/FK, relationships. Yeh Model layer hai.

    Suggested flow1) Classes list karo

    3) Relationships (1-M / M-M)
    4) Constraints (unique, nullable)

    Example

    class Lot(db.Model):
        id = db.Column(db.Integer, primary_key=True)
        name = db.Column(db.String(80), nullable=False)
        spots = db.relationship('Spot', backref='lot', lazy=True)

Advice: He was somewhat rude and uninterested right from the moment he joined the meet. As if someone was forcing him to take the viva. Cannot predict the behaviour of the examiner from this sheet. They behave differently with different students at different times. Maybe he was annoyed that I had hijacked his lunch hour. But he was patient. Did not interrupt. Gave time to figure out things when I got stuck once or twice. He wants detailed explanation. So explain everything about your app in complete details right from the start. Consume as much time as possible. Then he'll not bother to ask further questions. Practice the code changes that he asks, from this sheet. He always asks to do the same styling changes.
