    No code changes asked.
    Times asked 1
    Official solution

    Yeh MAD-1 viva question tumhare project ke context se linked hai. Short answer is structure se do:

    Pehle 1 line definition/purpose, phir tumhare project ka example, phir chhota code/flow.

    Typical Flask flowBrowser request → @app.route controller → SQLAlchemy model/DB → Jinja template response.

    Auth: session['user_id'] + role check. CRUD: add/commit, query.all, field update, delete.
    Live change maange to: related model → route → template, phir browser refresh karke dikhao.

    Example (generic create):
    obj = Model(name=request.form.get('name'))

    db.session.add(obj); db.session.commit()
return redirect(url_for('list_view'))

    SimpleGitHub repo public/private policy ke hisaab, MAD-1 collaborator add, commits dikhao.

    Repo → Settings → Collaborators → instructor added.
    Commits: git log / GitHub History — regular commits better, ek dum 1 commit suspicious.
    README + report mein AI usage likha hona chahiye agar use kiya.

    Suggested flow1) Concept kya hai?
    2) Mere code mein kahan?
    3) Example / demo
    4) Edge case

    Example

    # related file: models.py / routes / template

  4. 4
    6)How rbac is working (i implemented session so explained it)
    Times asked 2
    Official solution

    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().

    7) He asked have you used AI , I said I used so he asked how have you validated it is perfect or not or what did you learn
    Times asked 2
    Official solution

    SimpleValidation = input rules: required, email format, length, unique. Frontend UX, backend security — dono.

    Example

    if not email or '@' not in email:
    flash('Invalid email')
    return redirect(request.url)
if User.query.filter_by(email=email).first():
    flash('Email taken')
  6. 6
    8)Asked me to explain all API's
    Times asked 2
    Official solution

    Simple3–4 routes deep: auth, validation, status, cache? Method body response error.

    Login, list, create. Why each.

    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.

    Project example: Open resources, pick examiner's choice.

Advice: Be confident and explain your code thoroughly. All the best

    -Basic Questions about Celery and Redis
    Times asked 2
    Official solution

    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.

    -Vue and CLI questions
    Times asked 2
    Official solution

    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.

    What is caching and how you have implemented
    Times asked 1
    Official solution

    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').

    What is Redis?
    Times asked 21
    Official solution

    SimpleRedis fridge pe sticky note hai — poori kitchen (database) kholne ki zarurat nahi.

    Redis in-memory key-value store hai. Data RAM mein rehta hai, isliye disk wale SQLite/Postgres se kai guna tez.

    MAD2 mein Redis do kaam karta hai:
    1) Cache — same venue/show/dashboard JSON baar-baar DB se mat nikaalo.
    2) Celery message broker — Flask task queue mein daalta hai, worker uthata hai.

    Source of truth database hi hai. Redis band ho to cache miss ho jaata hai aur Celery queue ruk sakti hai. Crash pe cache gayab ho sakta hai — isliye important data sirf Redis mein mat rakho.

    Example

    import redis
r = redis.Redis(host='localhost', port=6379, db=0)
r.set('venues', json.dumps(data), ex=30)
print(r.get('venues'))

    Project example: GET /api/venues pehle Redis dekho. Miss pe SQLAlchemy query, phir SET with timeout. Celery worker Redis list se daily reminder uthata hai.

    Viva tipCache ke liye db=1, broker ke liye db=0 rakhna smart hai taaki keys mix na hon. Viva mein redis-cli ping → PONG dikhana strong hai.
