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'

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

Viva tipExact line yaad nahi to honestly related part dikhao. Bluff mat karo.

SimpleLive coding: notepad/editor mein chhota Flask route / Jinja loop / model field. Calm raho, run karke dikhao.

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

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.

SimpleJinja2 Flask ka template engine — HTML ke andar {{ }} variables, {% %} logic.

Example

{% for lot in lots %}
  <li>{{ lot.name }} — {{ lot.spots }}</li>
{% else %}
  <p>No lots</p>
{% endfor %}

SimpleLive Flask coding: chhota route likho, save, browser/curl se test. Syntax error terminal mein padho.

    return jsonify(ok=True)

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

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().

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)

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

SimpleBlacklist/block: user.status='blocked' check login/booking pe. Temporary flag vs hard delete permanent.

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'

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.

SimpleTemplate = HTML + placeholders. Jinja {{ }} / Vue template section. Data inject karke UI banata hai.

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')

SimpleLevel = viva difficulty band. Level 1 usually demo + basics; higher pe live coding + deeper theory.

Viva tipJo level assign hai uske hisaab se demo + theory ready rakho.

SimpleCamera pe clearly college/IITM ID dikhao — naam aur photo match hone chahiye.

Viva tipPehle se ID haath mein rakho, glare mat aane do. Iske baad GitHub + project run.

SimpleCode dikhao to pehle related file: models → route → template. Flow explain karte hue lines padho.

SimpleVue = UI ka smart assistant. Data badlo, screen khud update. MAD1 Jinja har click pe naya HTML.

Progressive frontend framework. Components, reactivity, directives.

MAD2 SPA: ek index.html, Vue Router pages, Flask sirf JSON.

Fayde: easy, SFC, docs. Vs React: templates HTML-like, course sikhata hai. Vs plain JS: baar-baar DOM mat chhedo.

Example

<!-- HelloWorld.vue -->
<template>
  <h1>{{ msg }}</h1>
</template>
<script>
export default { data() { return { msg: 'Hello' } } }
</script>

Project example: Navbar.vue + views (Login, Dashboard). data() / setup() reactive. fetch APIs.

Viva tipFayde: easy, SFC, reactivity. Vs React: chhota learning curve. Vs plain JS: UI state auto-update.

SimpleCode explain formula: input kya aaya → auth/validation → DB change → response/UI.

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

Viva tipPehle se ID haath mein rakho, glare mat aane do. Iske baad GitHub + project run.

SimpleGitHub repo open karo: commits, collaborators, README. Examiner check karta hai tumne khud kaam kiya.

Example

Settings → Collaborators
Commits: regular messages, last-day dump nahi.

Viva tipPrivate repo access pehle de do. Main branch submitted ZIP se match honi chahiye.
