MVC & DOM?

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.
3
Which language is used to manipulate DOM?

Times asked 1
Official solution

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
# formula: request → check/auth → DB → render/redirect
```

4
What's ORM? Which orm we've used?

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
```
5
How we're actually connecting the DB to flask, which cmnd? (with app.app_context: db.init(app))

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.

HTTP v/s HTTPS? Which is more secure and why?

Times asked 1

Official solution

SimpleHTTP postcard (koi padh le). HTTPS envelope (TLS lock).
Same headers, encrypted channel. MITM se password/token bachao. Local viva HTTP OK.
HTTP/1.1 version keep-alive. TCP neeche, TLS security layer, SMTP mail alag.
Browser + API ke beech extra darwaze: CORS origin allow, HTTPS encrypt transit, CSRF cookie-auto-send attack, XSS HTML inject, SQL injection raw query.
MAD2 SPA: Vue :8080 Flask :5000 → Flask-CORS. JWT localStorage XSS se chori ho sakta — v-html user input pe avoid. Password Network tab localhost pe dikhega; prod HTTPS, response mein password echo nahi.
401 unauthenticated, 403 unauthorized, 400 validation. Hash one-way — SHA decrypt nahi hota. Secret key .env, GitHub pe nahi.
Project example: Dev localhost http. Production https:// + cert.
Viva tipProtocols: HTTP/HTTPS app, TCP transport, TLS security, SMTP mail. HTTP/1.1 version — persistent connections.
8
Backref v/s backpopulates

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')
```
9
Get v/s Post. Which is more secure?

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')
```
10
How we send data to backend? (form action)

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
```
11
Can we send data through GET? How?

Times asked 1
Official solution

SimpleGET data mangta hai (read), POST data bhejta hai (create/submit).
GETURL mein dikhta hai, bookmark ho sakta hai, browser back/refresh safe hai, data URL query mein jaata hai. Search, page open, login form dikhana.
POSTbody mein data jaata hai, URL mein password nahi dikhta, refresh pe dubara submit ho sakta hai. Login, register, form save.
Example
# page dikhana
```
@app.route('/login', methods=['GET', 'POST'])
def login():
    if request.method == 'GET':
        return render_template('login.html')
    # POST: form submit
    email = request.form.get('email')
    ...
```
GET se theoretically data bhej sakte ho (?q=flask), lekin create/update ke liye nahi use karna — data log/history mein save ho jaata hai, length limit hoti hai.
HTML form default GET hota hai; method='POST' likhna zaroori hai login/register pe.

How did you implement search functionality in your project?

Times asked 1
Official solution

SimpleSearch: form/query param → ilike filter → results template.

```

Overall she was really nice and supportive. The viva lasted around 30 minutes. She joined 10 minutes early as my slot had been postponed by an hour but was also willing to give me time to prepare more if needed. She also let me rewind and restart a theory related answer from the beginning since I was struggling a bit to structure it at first. Also asked if she had any suggestions for me and she said she was impressed by my project and she didn't have a suggestion.

SimpleProject overview: problem → roles → main entities → key flows (register, book, admin approve).
Viva tip1 minute elevator pitch ready rakho, phir demo.

Advice: Prepare the commonly asked questions from this spreadsheet. Know your code and everything you have done in it and why you implemented it the way you did. Try to show your confidence, even if you're feeling nervous! Also take your time to answer questions and show the project.

id vs class, and using which symbol it is represented in css

Times asked 1
Official solution

Simple:class object/array/string dynamic CSS.
Purpose dynamic class. Error red.
Directives Vue ke special attributes hain — HTML ko superpower: v-if/v-show, v-for, v-bind (:), v-on (@), v-model.
v-if DOM se hataata/jodta. v-show sirf CSS display. Rare/permission: v-if. Bar-bar toggle: v-show. v-model two-way form. v-bind one-way JS→attribute.
:key v-for pe zaroori warna Vue galat reuse. v-html XSS. Secret UI ke liye sirf v-if kaafi nahi — API 403 bhi.
MAD1 Jinja server HTML. MAD2 yeh directives browser mein reactive.
Example
```
<div :class="{ 'text-danger': error, 'fw-bold': important }">Msg</div>
```
Project example: :class="{ 'text-danger': error }"

Times asked 1

Advice: The proctor is very patient, and cool. He didn't ask to complete the code modification in certain timeframe. Take your time. He kept asking, and I kept answering. He was impressed. At last, he stopped, and praised me. So, the moral of the story is: 1. You should know each and every part of your code, like your child. 2. The proctor will definitely ask for modifications in your code. 3. Theory - REST APIs, Models, Relationships are must.

# Spot.lot = db.relationship('Lot', back_populates='spots')
```
7
- can it return a boolean value

Times asked 1
Official solution

SimpleAPI = Application Programming Interface — do systems predefined rules se baat karti hain. REST API HTTP + JSON use karti hai.
Controller/route HTML bhi return kar sakta hai. REST API generally JSON return karti hai, frontend alag ho (Vue/Postman).
Example
```
@app.route('/api/users/<int:id>')
def get_user(id):
    u = User.query.get_or_404(id)
    return jsonify(id=u.id, name=u.name)
```
MAD1 HTML apps mein 'API' kabhi-kabhi routes ko hi keh dete hain. Agar Vue nahi to bolo: server-rendered Flask, JSON APIs optional.
Boolean return: technically jsonify(True) ho sakta hai, lekin meaningful JSON object better. Flask view None return kare to error.
Test: Postman se GET/POST.
Parsing: request.get_json() body se, request.args query se.

Change the constraints of email id . Should accept the email id only if it is in a format like somthing@somthing.something

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
```

Primary key foreign key

Times asked 1
Official solution

SimplePrimary key row ka unique identity — usually id Integer autoincrement.
Example
```
id = db.Column(db.Integer, primary_key=True)
```

Restful api

Times asked 3

Official solution

SimpleREST: resources + HTTP verbs. GET read, POST create, PUT/PATCH update, DELETE remove. Stateless ideal.
6
Get post

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')
```

Explain models used

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)
```

List and tuple difference

Times asked 1

Official solution

SimpleList changeable ordered, Tuple fixed ordered, Dict key-value.
list: [1,2,3] — append, mutable, duplicate ok. Arrays jaisa lekin mixed types.
tuple: (1,2) — immutable, dict key ban sakta hai.
dict: {'name':'Ram'} — fast lookup by key. JSON objects dict ban jaate hain.
set: unique items.
Array (JS) ≈ Python list. JS object ≈ Python dict.
Mutable: list, dict. Immutable: tuple, str, int.
