How did you implement authentication and authorisation in your project? Show the codes

Times asked 1
Official solution

SimpleAuthentication: tu kaun hai? (login). Authorization: tujhe permission hai? (role check).
Example
```
# auth
if check_password_hash(user.password, pwd):
    session['user_id'] = user.id

# authz
if user.role != 'admin':
    abort(403)
```

Learn the concept of session well

Times asked 1
Official solution

SimpleMAD1 mein usually session-based auth: login pe session['user_id'], har request pe verify.
Example
```
session['user_id'] = user.id
uid = session.get('user_id')
user = User.query.get(uid)
```
Viva tipSECRET_KEY set karo warna session insecure. logout pe session.clear().

Run me through the entire pipeline of staff dashboard - app.py as well as html pages

Times asked 1
Official solution

Simplevenv activate → dependencies → DB create/migrate → flask run. Browser pe localhost dikhao.
Example
```
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
flask run
```
6
Backref and backpopulates difference

Times asked 1
Official solution

Simplebackref reverse attribute auto banata hai. back_populates dono sides explicitly naam dete ho — clearer.
Example
```
# backref
spots = db.relationship('Spot', backref='lot')
# spot.lot available

# back_populates
spots = db.relationship('Spot', back_populates='lot')
# Spot.lot = db.relationship('Lot', back_populates='spots')
```

Advice: Read your entrie project thoroughly line by line before the viva. Any type of question based on your code may be asked. Very supportive and helps if you get stuck.

4) Asked Where is Your Model.

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)

```

7)Explain MVC Structure of your Code.

Times asked 1

Official solution

SimpleMVC: Model=data (SQLAlchemy), View=Jinja HTML, Controller=Flask routes/business logic.
Flask loosely MVC follow karta hai — routes controllers, templates views, models.py models.
6
9)What is the flow of your Login Page.

Times asked 1
Official solution

SimpleLogin flow pehle poochta hai "tu kaun hai?", token milne ke baad har API pe wohi proof dikhate ho.
Authentication step: Vue form email + password JSON POST karta hai. Flask user dhoondhta hai, check_password_hash se prove karta hai ki tum genuine ho. Galat 401. Sahi pe JWT + role milta hai — yeh session/token hai.
Vue localStorage (ya cookie) mein token rakhta hai, dashboard pe router.push. Aage ki har fetch header: Authorization: Bearer <token>. @jwt_required identity check (authentication). @roles_required('admin') permission check (authorization) — logged in ho, lekin allowed nahi to 403.
Validation alag cheez hai: empty email, password 8+ — form sahi bhara hai ya nahi. Woh identity prove nahi karta.
Logout = client token delete + login page. Server blacklist optional. Password response JSON mein kabhi mat bhejo.
Example
```
# Authentication
@app.route('/api/login', methods=['POST'])
def login():
    u = User.query.filter_by(email=data['email']).first()
    if not u or not check_password_hash(u.password, data['password']):
        return jsonify(msg='bad'), 401
    return jsonify(token=create_access_token(u.id), role=u.role)

# baad ki APIs
# Authorization: Bearer <token>
if current_user.role != 'admin':
    abort(403)
```
Project example: Login.vue POST /api/login → token LS → interceptor. Student token se admin route = 403. Empty form = validation, galat password = 401.
Viva tipNetwork tab mein password body dikhega localhost pe — prod HTTPS. Response mein hash/password echo mat karo.

Example
```
from werkzeug.security import generate_password_hash, check_password_hash
user.password = generate_password_hash(raw)
check_password_hash(user.password, raw)
```

12)Change the Position of your 'Already a user? Login.' in register.html to the top-right below Admin.

Times asked 1
Official solution

SimpleLive UI change: relevant CSS/HTML template kholo — color, margin, flex, bootstrap class. Save + hard refresh.
Example
```
/* button red */
.btn-primary { background: red; }

/* center navbar item */
.navbar { justify-content: center; }
```
Viva tipDevTools se pehle try, phir file mein permanent change.

Advice: Calm & Listen to everything without interrupting. Any line you think you don't know enough about.. Copy paste and read the explanation in brief. Understand the flow of every route used . For example.. Backend request data from Frontend..User Provides data.. Provided goes to this logic ..now route ask database for the data.. These lines process the data.. Return line render_template (display or push the data to frontend) For Coding just know 1)Login Route 2) Input from One Page output on othet (Route+ template) 3) Display any particular data.. blacklisted user /completed trek (model.query.filter_by(<condition>).all()) 4) Change in CSS

Show the table (database. Py or model. Py) 2.Show id card , git commit, collaborator 3.Write flask route for home page

Times asked 1
Official solution

SimpleLive Flask coding: chhota route likho, save, browser/curl se test. Syntax error terminal mein padho.
Example
```
@app.route('/ping')
def ping():
    return jsonify(ok=True)

@app.route('/even/<int:n>')
def even(n):
    return 'even' if n % 2 == 0 else 'odd'
```
2
Why we use if(__name__==__main__)

Times asked 1
Official solution

Simple
```
if __name__=='__main__' only when file run directly. Import pe nahi — app.run yahi. Remove import pe server start ho sakta.
```
Celery/tests import app without serving. Why used.
Flask Python micro web framework. Route decorator URL → function. MAD2 mein JSON API: request.get_json(), jsonify, JWT.
WSGI: server (Werkzeug) app ko call. if __name__ == '__main__' sirf direct run. Factory create_app() test/celery ke liye.
Blueprint/resources folders. @app.route vs MethodView. Debug=True viva local, prod nahi. CORS alag port Vue ke liye.
Project example: app.py bottom.

Times asked 1
Official solution

SimpleSECRET_KEY Flask ka secret jisse session cookies sign/encrypt hoti hain.
```

```
Iske bina session/flash unreliable ya insecure. Key leak = attacker session forge kar sakta hai.
Hardcode mat karo production mein — .env / environment variable. Flash messages bhi session use karti hain, isliye SECRET_KEY se related hain.
Hataane pe session kaam nahi / warning. Change karne pe purane sessions invalid.

Times asked 1
Official solution

{% endfor %}

{% block content %}{% endblock %}

{# home.html #}
{% extends 'base.html' %}
{% block content %}
  <h1>Home</h1>
{% endblock %}
```

Advice: Friendly examiner. Be ready to explain your project and make small code changes on the spot (e.g., adding a field or changing Bootstrap styles). Understanding your code is more important than memorizing definitions. And duration: ~30-35 minutes.

Advice: Keep your theory strong, be through with routes, models (db), and flask sessions. The examiner is a bit strict. Not intimidating enough to snatch your soul, but not friendly too. He won't help you. You are either on your own, or he'll explain the stuffs which you couldn't answer.
