He is very calm and asks easy and basic questions, know your project well both the code and the front end part(especially) he asks mainly from here only what feature you have implemented and how is it working, what is your logic in this project, just tell yours what you have implemented in your project. Here are some questions which I remember :

He asked me what is ORM and what are its adv I explained ORM and told some adv blindly which I mugged up but i understood one adv deeply and how it works behind I told him that I can recall one adv nicely rn he told me to explain it with an example, i explained , he listened paitently, i explained using my models.py file, i showed him in code how it will work if it was RAW SQL( it was the sql injection part, which hacker can try, if we won't have used ORM)

Times asked 1
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

Then he asked http methods for CRUD operations but I thought he is asking me to explain what are CRUD operations so I started but then he said methods so I explained the GET, POST, PUT, DELETE then he asked have you heard of PATCH then I explained it then he said ok, Thank you, That's all from my side" "Asked me to download the project from the portal. Asked why I was using a virtual environment (venv). Asked me to give a demo of the project. Asked what cascade=""all, delete-orphan"" means in models.py. Asked me to change the position of the Edit Profile button. Asked me to replace Edit Profile text on the button with the name of the currently logged-in student.

* Talk about Models and Relationships

Times asked 1
Official solution

Simpledb.relationship se object graph: lot.spots, booking.user. backref reverse side auto deta hai.
Example
```
spots = db.relationship('Spot', backref='lot', cascade='all, delete-orphan')
```
3
* What is the function of the "name" attribute in a form.

Times asked 1
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
```

* Coding Question - creating a route to basically display user detail and the trek details of what they booked.

Times asked 1

Official solution

SimpleLive coding: notepad/editor mein chhota Flask route / Jinja loop / model field. Calm raho, run karke dikhao.
5
* More on Forms - POST, GET

Times asked 1
Official solution

SimpleGET data read/show karta hai (idempotent). POST create/submit karta hai (form).
Example
```
@app.route('/login', methods=['GET', 'POST'])
def login():
    if request.method == 'POST':
        # validate + session
        ...
    return render_template('login.html')
```
6
* How to get retrieve data from a search input (query parameter)

Times asked 1
Official solution

SimpleQuery params URL ? ke baad: /search?q=mall. Flask: request.args.get('q').
Example
```
@app.route('/search')
def search():
    q = request.args.get('q', '')
    return ...
```
7
* Flask Login - current_user - why is it used or preferred

Times asked 1
Official solution

SimpleFlask lightweight Python web framework — routes, request/response, templates. MAD1 ka backend yahi hai.
Example
```
from flask import Flask
app = Flask(__name__)

@app.route('/')
def home():
    return 'Hello'
```
Viva tipFlask micro hai: jo chahiye (DB, login, forms) khud jodte ho.

Advice: Amazing proctor, extremely kind. Know your written work (code and theory concepts) well.

write the frontend and backend for fully booked slots

Times asked 1
Official solution

SimpleNaya Flask route: URL, method, auth if needed, query, jsonify. Postman pehle.
Examiner number/filter change easy rakhna. CORS. Frontend tabhi jab bole.
Status codes sahi. Password JSON mein nahi.
Examiner 2 cheezein: simple desi line + tumhare project ki exact file.
Pehle ID, GitHub, portal ZIP. Phir run: Redis + Flask + worker + beat + Vue. Feature demo: login, RBAC, cache hit/miss, Celery mail, search.
Line pe ungli: input kahan, kaunsa check, query/cache/task, JSON/UI. Copilot band. Jo nahi kiya honestly bolo + kaise add karte.
Example
```
@app.route('/api/sum', methods=['POST'])
def sum_num():
    d = request.get_json()
    return jsonify(result=d['a'] + d['b'])
```
Project example: resources.py new Resource. Test Thunder. Optional Vue fetch.

in between he asked the difference between put & patch

Times asked 1
Official solution

SimplePOST naya janam (har baar naya id). PUT poori photo replace. PATCH sticker chipkao.
POST create, not idempotent. PUT full update, idempotent. PATCH partial.
POST ki jagah PUT se REST semantics toot. GET typically no body.
CRUD map: POST create, GET read, PUT/PATCH update, DELETE delete.
Pehle 1-line definition, phir related MAD2 layer (Vue SFC / Flask route / models.py / tasks.py / Redis).
4-line formula: input kahan se aaya, auth/validation kaunsa, DB ya cache ya Celery, kya return.
Related mix mat karo — cache ≠ Celery, authentication ≠ authorization, v-if ≠ v-show, Beat ≠ Worker. Follow-up ke liye ek difference ready rakho.
Example
```
POST /api/venues
PUT  /api/venues/1   {all fields}
PATCH /api/venues/1 {only name}
```
Project example: POST /api/venues create. PUT /venues/1 saari fields. PATCH sirf name.

Times asked 1

def ping():
 return jsonify(ok=True)

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

write jinja loop for showing the trekkers Theory:

Times asked 1
Official solution

SimpleJinja for loop list render karta hai. loop.index, else branch empty list pe.
Example
```
{% for u in users %}
 <tr><td>{{ loop.index }}</td><td>{{ u.email }}</td></tr>
{% endfor %}
```
4

difference between status codes starting from 4 and 5 (client side problem vs server side problem)

Times asked 1

Official solution

SimpleStatus code server ka result: 200 OK, 302 redirect, 400 bad input, 401/403 auth, 404 not found, 500 server error.
5
authentication vs authorization He didn't ask many questions cuz I was a little slow to answer.. hope I pass 🙏

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)
```

Advice: sir is patient, there were audio issues, but he repeated himself a few times. the first theory question wasn't from this sheet so expect unconventional questions.
