As i don't have instance folder , she asked me to quickly do a demo of project ( this demo only went around 20 mins for me bcs she said wait , and was very quite and again she came like that ) Theory questions :

Times asked 1

Official solution

SimpleTheory = concepts: ORM, MVC, auth vs authz, Jinja inheritance, sessions. 1-line def + project example.
4
What is ORM

Times asked 4
Official solution

SimpleORM = Object Relational Mapping. Tables → Python classes. Raw SQL kam likhte ho.
Example
```
class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(120), unique=True)

User.query.get(5)  # SELECT ... WHERE id=5
```
5
Analogy for SQL and SQLAlchemy

Times asked 1
Official solution

SimpleSQLAlchemy MAD1 ka common ORM. Flask-SQLAlchemy wrapper se db.Model, db.session.
Example
```
user = User(email='a@b.com')
db.session.add(user)
db.session.commit()
users = User.query.filter_by(role='admin').all()
```

What does create_app.py file do ??

Times asked 1
Official solution

SimpleApplication factory: create_app() function mein app banate ho — config, blueprints, DB init yahin.

    db.init_app(app)
    app.register_blueprint(auth_bp)
    return app
```

Show ur models ( just show )

Times asked 1
Official solution

Simplemodels.py = har table ki class: columns, PK/FK, relationships. Yeh Model layer hai.
Suggested flow1) Classes list karo
2) Har table ka kaam 1 line
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)
```

SimplePehle 1-line definition, phir apne MAD1 project mein file dikhao, phir chhota example.
Suggested flow1) Concept kya hai?
2) Mere code mein kahan?
3) Example / demo
4) Edge case
Example
```
# related file: models.py / routes / template

What is inline,internal, external CSS

Times asked 1

Official solution

SimpleCSS 3 tarikon se lagti hai, priority Inline > Internal > External (same specificity pe).
Inline: style='color:red' element pe. Highest priority, lekin reuse nahi. Debugging mushkil.
Internal: <style> tag HTML head mein. Us page tak limited.
External: style.css file. Large project ke liye best — ek jagah change, saari pages update.
Example same button pe teeno:
/* external */ .btn { color: blue; }
/* internal */ .btn { color: green; }
 <button class='btn' style='color:red'> → red jeetega
ID (#box) class (.btn) se strong, class element (button) se strong.
!important sabko override karta hai — avoid karo.
Large project: external CSS preferred.
