Official solution

SimpleExaminer portal wala submitted ZIP chahta hai. Local extra changes mat dikhana.
Suggested flow1) Portal ZIP download
2) Extract
3) venv + pip install -r requirements.txt
4) flask run / python app.py

While setting it up, I messed up during virtual environment (venv) creation, so I politely asked if I could create it again. He simply said yes, so don’t panic if something like that happens.

Times asked 1
Official solution

SimpleVirtualenv isolated Python env — project deps system Python ko nahi bigaadte.
Example
```
python -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt
```

Create a route that accepts input

Times asked 1

Official solution

SimpleDemo script pehle se practice: 5–7 min, Admin + User roles, saare mandatory features.
Suggested flow1) Register/login user
2) Admin login — CRUD
3) Approval/blacklist
4) Booking/apply + edge case
5) Search
6) Logout
Viva tipBolte-bolte dikhao. Code tab kholna jab poochhein.

Show that form data on another page

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
```
10
Write the template for it as well

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.
11
So be prepared for basic Flask route + form handling + template rendering.

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'
```
12

Theory questions asked:

Times asked 1

Official solution

SimpleTheory = concepts: ORM, MVC, auth vs authz, Jinja inheritance, sessions. 1-line def + project example.
13
HTTP Methods in detail

Times asked 1
Official solution

SimpleHTTP verbs REST ke tools. Methods HTTP ke hain, REST unhe convention se use karta hai.
GET read cacheable. POST create payload. PUT replace. PATCH patch. DELETE remove.
GET exists bina REST ke bhi — browser address bar.
HTTP verbs + status REST ki zabaan. GET read, POST create, PUT replace, PATCH partial, DELETE remove. GET typically no body.
Status: 200 OK, 201 created, 202 accepted (Celery task), 400 bad input, 401 no/bad token, 403 role nahi, 404 missing, 409 conflict (double book), 500 server.
AJAX/fetch page reload nahi. SPA poori isi pe. Postman se bina Vue ke API prove karo — examiner pasand.
Example
```
GET /api/venues
POST /api/venues
PUT /api/venues/1
DELETE /api/venues/1
```
Project example: resources.py methods list. Postman 4-5 calls.
Viva tipGET typically no body (cacheable). POST/PUT/PATCH haan payload. PUT idempotent, POST nahi.
14

MVC architecture

Times asked 1

Official solution

SimpleMAD1 typical: Browser → Flask routes → validate/auth → SQLAlchemy → SQLite → Jinja response.
Suggested flowRequest → Route → Auth check → DB → render_template / redirect
15

RESTful characteristics

Times asked 1

Official solution

SimpleREST: resources + HTTP verbs. GET read, POST create, PUT/PATCH update, DELETE remove. Stateless ideal.
16

Viva tipFunction signature + 3-4 important lines + edge case.

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
```

Mr.gentleman said role based access list.

Times asked 1

What is CORS

Times asked 1
Official solution

SimpleDifferent origin Vue vs Flask — browser CORS check. Server Allow-Origin.
Failed = frontend error even if curl works. Examiner curl vs browser.
HTTP verbs + status REST ki zabaan. GET read, POST create, PUT replace, PATCH partial, DELETE remove. GET typically no body.
Status: 200 OK, 201 created, 202 accepted (Celery task), 400 bad input, 401 no/bad token, 403 role nahi, 404 missing, 409 conflict (double book), 500 server.
AJAX/fetch page reload nahi. SPA poori isi pe. Postman se bina Vue ke API prove karo — examiner pasand.
Example
```
from flask_cors import CORS
CORS(app, resources={r'/api/*': {'origins': 'http://localhost:8080'}})
```
Project example: Flask-CORS localhost:8080.

Explain Stateless HTTP

Times asked 1

Official solution

SimpleCode explain formula: input kya aaya → auth/validation → DB change → response/UI.
Viva tipFunction signature + 3-4 important lines + edge case.
3
PUT and 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.

Advice: 1. Go through your code 2. Prepare to write a simple route 3. Prepare to write a simple jinja2 for loop

Simpletry/except. Catch Exception not BaseException (SystemExit). IntegrityError 404 abort.
Exception handling. Types ValueError TypeError KeyError IntegrityError HTTPException.

Related mix mat karo — cache ≠ Celery, authentication ≠ authorization, v-if ≠ v-show, Beat ≠ Worker. Follow-up ke liye ek difference ready rakho.
Example
```

except IntegrityError:
    db.session.rollback()
