Simple2xx jeet, 4xx teri galti, 5xx meri (server) galti.

200 OK, 201 Created, 400 validation, 401 no/invalid token (authentication fail), 403 role (authorization fail), 404 missing, 409 conflict, 500 crash.

403 vs IntegrityError: 403 permission. Duplicate unique → 400/409, 500 mat chhodo.

Example

return jsonify(msg='ok'), 200
return jsonify(msg='login required'), 401

Project example: Login fail 401. User admin API 403. Duplicate booking 400.

Viva tip403 vs IntegrityError: 403 permission, IntegrityError DB constraint (duplicate unique) — 400/409 banao, 500 mat chhodo.

SimpleJWT teen tukde ki signed chitthi: header.payload.signature. Padhi ja sakti hai, badli nahi ja sakti.

Encoded (Base64) + signed, encrypted nahi (JWE alag). Payload mein password mat daalo — koi jwt.io pe dekh lega.

Login pe server secret se HMAC (HS256). Har API Authorization: Bearer <token>.
Expiry exp. Change payload → signature fail → 401.

Session MAD1 server yaad rakhta. JWT MAD2 client rakhta, server stateless-ish.

Example

eyJhbGciOiJIUzI1NiJ9.{"sub":1,"role":"admin"}.signature
# Authorization: Bearer <token>

Project example: POST /login → token LS. fetch interceptor header. @jwt_required APIs.

Viva tipAlgo HS256. Secret env var. jwt.io pe payload dikhao, secret public site pe mat paste.

SimpleSMTP = Simple Mail Transfer Protocol — email bhejne ka standard. Flask-Mail / smtplib se reminders/reports.

Example

from flask_mail import Message
msg = Message('Subject', recipients=[user.email])
msg.body = 'Hello'
mail.send(msg)

Viva tipViva mein MailHog/inbox dikhao. Port 587 TLS common; local pe MailHog 1025.

SimpleLive jobs: Redis, worker, beat, crontab abhi, logs + email/CSV.

Scheduled vs user-triggered dono dikhao. Missing feature honestly.

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.

Suggested flow1) redis

Example

CELERY_BEAT_SCHEDULE = {
  'daily-reminder': {
    'task': 'jobs.daily_reminder',
    'schedule': crontab(hour=18, minute=0),
  },
}

Project example: Change schedule current time. MailHog. Export button 202.

Project example: resources.py new Resource. Test Thunder. Optional Vue fetch.

SimpleCDN = Vue script tag se, jaise pen drive. CLI/Vite = poori factory (SFC, npm, bundle).

CDN: no build, chhote apps, exam PC pe Node nahi to bhi chal. Weak: no .vue compile, 3rd-party cache, scale/team.

CLI/Vite: Single File Components, env, code-split, production dist/. Scalable.

Examiner 'which + why' — jo use kiya wahi justify, doosra naam rato mat.

Example

<!-- CDN -->
<script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>

# Vite
npm run dev
npm run build

Project example: CDN: index.html unpkg vue. CLI: package.json, npm run serve / vite.

Viva tipCDN scalable large teams ke liye weak (no SFC compile, caching 3rd party). Examiner 'which + why' poochta hai — jo use kiya wahi justify karo.

SimpleLifecycle = component ki zindagi ke stages. API call tab jab DOM ready ho — mounted.

created: instance bani, this data, DOM nahi. mounted/onMounted: page pe aa gaya — fetch, Chart.js, setInterval.
updated: data change ke baad. unmounted: cleanup (clearInterval) warna memory leak.

Dashboards onMounted isliye: canvas/API tab valid. created mein $el nahi.

Composition: onMounted(() => {}) setup ke andar.

Example

export default {
  async mounted() {
    const r = await fetch('/api/venues')
    this.venues = await r.json()
  }
}

Project example: Venues.vue mounted fetch list. Clock component unmounted pe interval clear.

Viva tipcreated: data setup, DOM nahi. mounted/onMounted: $el mil gaya — fetch yahi. Dashboards isliye onMounted use karti hain.

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

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.

SimpleBlueprint se app ko modules mein todte ho — auth, admin, user alag files. Scale + clean structure.

Example

auth_bp = Blueprint('auth', __name__, url_prefix='/auth')

@auth_bp.route('/login')
def login(): ...

app.register_blueprint(auth_bp)

Viva tipViva: 'kyun blueprint?' → separation of concerns, badi app maintainable.

SimpleViva wrap-up hai. Short thanks + confirm submission ZIP latest hai.

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.

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

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.

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

Simplecommit changes save. rollback fail pe undo. Transaction consistency ke liye.

Example

try:
    db.session.add(obj)
    db.session.commit()
except Exception:
    db.session.rollback()
    raise

SimpleMAD1 frontend usually Jinja templates + HTML/CSS/Bootstrap (+ thoda JS). MAD2 pe Vue ho to clearly bolo.

SimpleCache = pehli baar hisaab karke copy rakh lo, doosri baar copy dikha do.

Baar-baar same expensive kaam (DB query, counting bookings) mat karo. Result Redis jaise store mein timeout ke saath rakh do.

Cache hit: key mil gayi, DB skip. Cache miss: DB se lao, SET karo, return karo.

Tradeoff: speed vs stale data. Admin naya venue add kare aur cache 50s ka ho to user purani list dekh sakta hai — isliye write pe invalidation zaroori hai.

Browser cache, Flask-Caching, Redis alag layers hain. MAD2 examiner Redis + @cache.cached code dekhta hai.

Example

@cache.cached(timeout=50, query_string=True)
@app.route('/api/shows')
def shows():
    return jsonify([s.serialize() for s in Show.query.all()])

Project example: Admin dashboard counts / venues list cache. Create/update/delete ke baad cache.delete('venues').

Viva tipprint('DB queried') function ke andar laga ke miss/hit demo karo — hit pe print nahi chalega.

SimpleRedis box hai, Celery us box se kaam uthane wala worker hai — same cheez nahi.

Redis: store (cache keys) + queue (broker lists).
Celery: Python library jo tasks define karti hai, .delay() se queue mein daalti hai, worker execute karta hai.

Dono localhost pe ho sakte hain. Alag Redis DB index use karo. Redis band = cache miss + Celery stuck.

Example

Celery: broker_url='redis://localhost:6379/0'
Cache:  CACHE_REDIS_URL='redis://localhost:6379/1'

Project example: export_csv.delay(user_id) Flask se. Worker Redis se task uthata hai, CSV+email. Cache alag keys venues.

Viva tipAgar possible ho to cache db=1, broker db=0 — keys mix nahi hoti.
