Advice: He was very Chill. All the questions he asked were already in sheet. Time was 6pm but he joined 6:15 bcoz of something, still he was calm and didn't rush me for anything. Gave me time for doing what he asked, like installing the dependencies and all takes time. I was kind of just notifiying him like backend is running now, redis-server is running... Between these installs, there was complete silence, he didn't ask anything and I was just saying things after completing them or when he asked. Be calm, explain everything confidently. All the Best!!

Advice: He was very nonchalant , he will ask a question and won't ask any cross question until you answer it or directly tell him you don't know... Viva was exactly for 30 minutes One thing that can impress him is , whatever functionality he asks , know where that part of code is , in your project . He won't talk much , but he is not very strict too.... The coding questions are repeated . So make sure to go through the spreadsheet..Btw mine was level 1 He is very patient and waits for you to search your file . Just don't stay silent

   Community 0 My solution Times asked 2

Advice: I stored my token in the localStorage and then from the localStorage I stored that in a Vuex.store object but according to him I was able to access the page even after reloading even though I was using Vuex.store. He asked me why and I couldnot figure it out at that moment. Neither could he... That took the last few minutes we had. I later found out that immediately after creating the Vuex.store object we are setting it from localStorage so that why it gets rewritten upon a hard-reload Proctor 'sounds' young and chill.... Just know your stuff and you are good to go... Good Luck :)

1. 1
   Use of Redis Code changes:

   See solution Community 0 My solution Times asked 1

   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.
2. 2
   Change the color of the button(frontend)

   See solution Community 0 My solution Times asked 1

   Official solution

   SimpleLive UI change: relevant CSS/HTML template kholo — color, margin, flex, bootstrap class. Save + hard refresh.

   Example

   /* button red */
   .btn-primary { background: red; }
   
   /* center navbar item */
   .navbar { justify-content: center; }

   Viva tipDevTools se pehle try, phir file mein permanent change.

Advice: Just be aware of your code which line has the code for which feature. He asks it for sure. Then make sure to be ready to change the minor code changes like I have mentioned. He is chill. Ended by saying all the best for Level 2

   Example

   class User(db.Model):
       id = db.Column(db.Integer, primary_key=True)

6. 6
   What is SQL injection

   See solution Community 0 My solution Times asked 1

   Official solution

   SimpleUser input concat query. ORM bound params bachata. text()+user mat.

   SQLAlchemy injection still if format SQL.

   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.

   Example

   # bad: f"SELECT * FROM user WHERE name='{name}'"
   User.query.filter_by(name=name)  # good

   Project example: filter_by(name=name) good.

   What is payload.

   See solution Community 0 My solution Times asked 1

   Official solution

   SimplePayload = dabba ke andar samaan (body). JWT payload beech wala claims (encrypted nahi).

   POST haan JSON. GET query string. JWT payload vs HTTP payload alag context.

   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.

   Project example: request.get_json() create venue. Token payload user id jwt.io.
5. 5
   Show that Admin can search for companies and Students 7)Show that user can edit their profile. ( I showed resume submission and viewed the pdf too)

   See solution Community 0 My solution Times asked 1

   Official solution

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

   Example

   q = request.args.get('q', '').strip()
   lots = Lot.query.filter(Lot.name.ilike(f'%{q}%')).all()

Advice: Remember the basics. I have not received my score yet so I can't say how my strategy was. I downloaded my code from portal and made a virtual environment upfront instead of doing checksum, proctor was fine with both. Spent majority of my time explaining my code thoroughly when showing my website, showing features, database, how my database updated and stuff. Sir didn't ask questions when I was explaining. After that he asked about the things I questions.

   Asked difference between filter and filter by

   See solution Community 0 My solution Times asked 1

   Official solution

   Simplefilter_by simple keyword arguments, filter full SQL-style conditions.

   User.query.filter_by(email='a@x.com').first()  # column=value, easy
   User.query.filter(User.age > 18, User.city == 'Delhi').all()  # comparisons, OR, LIKE

   filter_by sirf equals ke liye. Greater-than, LIKE, joins ke liye filter() use karo.

   Example search

   Trek.query.filter(Trek.name.ilike(f'%{q}%')).all()

   Yeh filter_by se nahi hoga.

   - what are http methods

   See solution Community 0 My solution 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.

           # validate + session

   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

   @celery.task
   def export_venues_csv(user_id):

   6.explain handling duplicate booking

   See solution Community 0 My solution Times asked 2

   Official solution

   SimpleDoosri booking same slot: unique constraint + query.exists + 400 message.

   Frontend disable UX. Backend source of truth. Race: two users unique(slot).

   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

   if Booking.query.filter_by(user_id=uid, slot_id=sid).first():
       return jsonify(message='Already booked'), 400

   Project example: Click book twice. Second 400 Already booked. DB unique.

   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)

   Official solution

   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')

Advice: Suggestions/Tips Read your entire code thoroughly. Know your frontend, backend, database, and execution flow. Understand every feature you implemented. Practice basic SQL queries. Be honest if you don't know an answer—the examiner is helpful, but you should know your own code.

   Asked questions on redis, celery

   See solution Community 0 My solution 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.

   - Webhooks lifecycle and how do we use them in an app

   See solution Community 0 My solution Times asked 2

   Official solution

   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.

   user = User.query.get(uid)

Advice: He was very Chill. All the questions he asked were already in sheet. Time was 6pm but he joined 6:15 bcoz of something, still he was calm and didn't rush me for anything. Gave me time for doing what he asked, like installing the dependencies and all takes time. I was kind of just notifiying him like backend is running now, redis-server is running... Between these installs, there was complete silence, he didn't ask anything and I was just saying things after completing them or when he asked. Be calm, explain everything confidently. All the Best!!

    What is MVC

    See solution Community 0 My solution Times asked 3

    Official solution

    SimpleMVC = Model-View-Controller. Code ko 3 hisson mein baant ta hai taaki mix na ho.

    Model: data + DB. models.py — User, Trek, Booking classes.
    View: jo user dekhta hai. templates/*.html + Jinja.
    Controller: beech ka logic. routes / app.py — request lo, model se data, view ko do.

    Example flow (register):
    Browser form POST → Controller register() → User model save → redirect → View dashboard.html

    Draw: Browser → Controller → Model → DB, phir Controller → View → Browser.
    ORM na ho to bhi MVC ho sakta hai — Model raw SQL functions ho sakte hain. Structure matter karta hai, library nahi.
    MVP/MVVM doosri architectures hain; MAD1 mein MVC expected hai.

Advice: He was very nonchalant , he will ask a question and won't ask any cross question until you answer it or directly tell him you don't know... Viva was exactly for 30 minutes One thing that can impress him is , whatever functionality he asks , know where that part of code is , in your project . He won't talk much , but he is not very strict too.... The coding questions are repeated . So make sure to go through the spreadsheet..Btw mine was level 1 He is very patient and waits for you to search your file . Just don't stay silent

   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

   What are HTTP status/error codes? like 201, 403 etc.

   See solution Community 0 My solution Times asked 2

   Official solution

   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.

   Are JWT tokens encrypted or encoded? What is their purpose?

   See solution Community 0 My solution Times asked 1

   Official solution

   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.

3. 3
   login as company, login as student, create drive, apply as student to drive, export csv(basically any random subset of core requirements)

   See solution Community 0 My solution Times asked 2

   Official solution

   SimpleClick → Celery → worker CSV → email/download. Columns verify.

   csv module. Auth required. Don't freeze UI — 202 + poll.

   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.

   celery beat worker

   See solution Community 0 My solution Times asked 2

   Official solution

   SimpleBeat clock hai, Worker haath hai. Clock kaam nahi karti, haath nahi sochte kab.

   Worker: @celery.task execute. Beat: crontab padhke due time pe queue mein daal.
   Sirf worker = scheduled nahi. Sirf beat = queue bhar jaaye, koi run nahi.

   Dono ke saath redis-server. Logs mein 'Sending due task' Beat, 'Task succeeded' Worker.

   Example

   celery -A app.celery worker -l info
   celery -A app.celery beat -l info

   Project example: daily_reminder Beat 18:00. Worker MailHog. Export worker-only (button).

   Viva tipSirf worker = scheduled jobs nahi chalenge. Sirf beat = queue bhar jaaye, koi run nahi karega.

    redis working

    See solution Community 0 My solution Times asked 2

    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.

    vue cycles

    See solution Community 0 My solution 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' } } }

    Cdn vs cli

    See solution Community 0 My solution Times asked 3

    Official solution

    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.

Advice: He is nice just comes late everytime and enjoys the viva and helps you

   See solution Community 0 My solution Times asked 2

   Official solution

   Yeh project-specific feature add/modify hai. 4 layers touch karo: model, route, template, validation.

   1) Data chahiye to models.py mein column/relationship + DB update (ALTER / migrate / create_all).
   2) Route: GET pe form/page, POST pe request.form se save, flash + redirect.
   3) Template: input name=... Jinja se {{ obj.field }} display.
   4) Rule: duplicate, range, role check backend pe.

   Example naya field 'city':

   user.city = db.Column(db.String(50))
   user.city = request.form.get('city')
   <input name='city'>  ...  {{ user.city }}

   I did everything correct but I answer one question wrong so he gave me a chance and ask what is orm and it's benefits. That's all in 27 minutes session.

   See solution Community 0 My solution 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

Advice: Theory questions are generally same . He only ask about caching,redis,ORM,vue lifecycle hooks. The overall experience was good and don't wry just know your code well and you are good to go . Idk why he told me to do changes in Level 1. All the best.

   - Celery task modification

   See solution Community 0 My solution Times asked 2

   Official solution

   SimpleCelery = background naukri. HTTP request ko 10 second email bhejne ke liye mat rokna.

   Distributed task queue: aap function ko abhi nahi, worker process mein later/retry/schedule pe chalaate ho.

   MAD2 typical jobs: daily reminder mail, monthly HTML report, user-triggered CSV export.

   Web request 200ms hona chahiye. 10,000 emails request thread mein = timeout. Worker alag CPU pe kaam kare.

   Redis broker chahiye. Beat alag process schedule ke liye.

   Example

   @celery.task
   def daily_reminder():
       for u in User.query.filter_by(active=True):
           send_mail(u.email, 'Book something today!')

   Project example: User Export click → 202 Accepted. Worker CSV + email. Daily 6pm Beat reminder.

   Viva tipWorker + Redis bina Beat ke user-triggered chalega. Scheduled jobs ke liye Beat bhi chahiye.

   - Cache and its implementation

   See solution Community 0 My solution Times asked 2

   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').

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

   See solution Community 0 My solution Times asked 2

   Official solution

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

   what is vue lifecycle

   See solution Community 0 My solution Times asked 1

   Official solution

   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.

He asked me why and I couldnot figure it out at that moment. Neither could he... That took the last few minutes we had. I later found out that immediately after creating the Vuex.store object we are setting it from localStorage so that why it gets rewritten upon a hard-reload Proctor 'sounds' young and chill.... Just know your stuff and you are good to go... Good Luck :)

   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)

   Do you know caching?

   See solution Community 0 My solution Times asked 2

   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').

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

   Why you have used redis?, how fast it is?

   See solution Community 0 My solution Times asked 2

   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.

    SimpleDecorator + Redis ping + invalidation line + miss/hit demo idea.

    Kaunsi routes, timeout, key_prefix, query_string. POST pe nahi.

    print after set sirf miss. Timeout chhota karke expiry.

    Redis in-memory key-value store hai — fridge pe sticky note, poori kitchen (SQL database) har baar mat kholo.

    MAD2 mein Redis do kaam: (1) cache — same venues/shows/dashboard JSON baar-baar DB se nahi (2) Celery broker — Flask task queue mein daalta hai, worker uthata hai.

    Flow: cache.get(key) → hit pe return, miss pe SQLAlchemy + SET with timeout. Admin write ke baad cache.delete, warna stale list.

    Source of truth database hi hai. Redis crash/band = cache miss (app chalni chahiye) + queue ruk sakti hai. Important bookings sirf Redis mein mat rakho.

    Alag: Redis ≠ Memcached (Celery broker nahi). Redis ≠ localStorage (woh browser). redis-cli ping → PONG viva proof.

    Official solution

    SimpleAuthentication poochta hai "tu kaun hai?", Authorization poochta hai "tujhe yeh kaam karne ki permission hai?"

    Authentication: login. Username + password check karke prove karte ho ki tum genuine user ho. Success pe session/token milta hai.
    Authorization: uske baad role check. Admin hi parking lot / venue / drive delete kar sakta hai, normal user nahi.

    MAD2 mein yeh alag layers hain: login API = authentication (JWT milta hai). @roles_required('admin') ya Vue v-if="isAdmin" = authorization.

    Validation alag cheez hai (form sahi bhara hai ya nahi, jaise age 18+). Authentication identity hai, authorization permission, validation input quality.

    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.

    Problem: repeated reads, slow page, extra load. Cache seconds ke liye snapshot deta hai.

    Nahi use karna: har second badalne wala live stock, user-private secret data bina soch ke (key mein user_id hona chahiye).

    Memoization caching ka subset hai (function args). HTTP 304 / browser cache alag layer.

    Redis in-memory key-value store hai — fridge pe sticky note, poori kitchen (SQL database) har baar mat kholo.

    MAD2 mein Redis do kaam: (1) cache — same venues/shows/dashboard JSON baar-baar DB se nahi (2) Celery broker — Flask task queue mein daalta hai, worker uthata hai.

    Flow: cache.get(key) → hit pe return, miss pe SQLAlchemy + SET with timeout. Admin write ke baad cache.delete, warna stale list.

    Source of truth database hi hai. Redis crash/band = cache miss (app chalni chahiye) + queue ruk sakti hai. Important bookings sirf Redis mein mat rakho.

    Alag: Redis ≠ Memcached (Celery broker nahi). Redis ≠ localStorage (woh browser). redis-cli ping → PONG viva proof.

    SimpleMAD2 course Redis isliye: ek tool mein cache + Celery broker.

    Memcached sirf cache. RabbitMQ sirf queue. Redis dono + easy install.

    Student project size pe SQLite + Redis kaafi. Production mein hosted Redis, persistence optional.

    Redis in-memory key-value store hai — fridge pe sticky note, poori kitchen (SQL database) har baar mat kholo.

    MAD2 mein Redis do kaam: (1) cache — same venues/shows/dashboard JSON baar-baar DB se nahi (2) Celery broker — Flask task queue mein daalta hai, worker uthata hai.

    Flow: cache.get(key) → hit pe return, miss pe SQLAlchemy + SET with timeout. Admin write ke baad cache.delete, warna stale list.

    Source of truth database hi hai. Redis crash/band = cache miss (app chalni chahiye) + queue ruk sakti hai. Important bookings sirf Redis mein mat rakho.

    Alag: Redis ≠ Memcached (Celery broker nahi). Redis ≠ localStorage (woh browser). redis-cli ping → PONG viva proof.

    Project example: requirements.txt: redis, Flask-Caching, celery. README: redis-server pehle chalao.

    SimpleCelery = background naukri. HTTP request ko 10 second email bhejne ke liye mat rokna.

    Distributed task queue: aap function ko abhi nahi, worker process mein later/retry/schedule pe chalaate ho.

    MAD2 typical jobs: daily reminder mail, monthly HTML report, user-triggered CSV export.

    Web request 200ms hona chahiye. 10,000 emails request thread mein = timeout. Worker alag CPU pe kaam kare.

    Redis broker chahiye. Beat alag process schedule ke liye.

    Example

    @celery.task
    def daily_reminder():
        for u in User.query.filter_by(active=True):
            send_mail(u.email, 'Book something today!')

    Project example: User Export click → 202 Accepted. Worker CSV + email. Daily 6pm Beat reminder.

    Viva tipWorker + Redis bina Beat ke user-triggered chalega. Scheduled jobs ke liye Beat bhi chahiye.

    How do Celery and Redis work together?

    See solution Community 0 My solution Times asked 1

    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.

    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

    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.

    What is MVC?

    See solution Community 0 My solution Times asked 9

    Official solution

    SimpleModel-View-Controller separation of concerns.

    Map folders. Vue is V. Flask routes C. models M.

    MAD2 architecture: Vue SPA (client) → HTTP JSON → Flask API (server) → SQLAlchemy DB. Side path: Flask → Redis broker → Celery worker → MailHog/CSV.

    Client-server alag ports. State: Vue memory + LS token. Persistent: SQLite. Cache: Redis. MVC-ish: models.py, API views, Vue templates.

    Scale: more workers, Postgres, cache, not 'bigger SQLite file'.

    Example

    Vue Booking.vue → POST /api/book → Booking model → jsonify → this.bookings.push

    Project example: See architecture essay.

    What are Webhooks?

    Official solution

    SimpleWebhook = woh tumhe call karta hai. API = tum unhe call karte ho.

    Payment success pe Stripe tumhare /webhooks/payment pe POST. Tum poll nahi karte.

    API pull, webhook push. WebSocket dono taraf live connection. SSE server→client stream.

    MAD2 mostly REST APIs. Webhook theory + example kaafi. Verify signature production mein.

    Example

    @app.route('/webhooks/payment', methods=['POST'])
    def hook():
        event = request.json
        ...

    Project example: Agar implement nahi: 'course REST. Webhook design: POST /webhooks/booking-paid'.

    Viva tipAPI pull, webhook push. WebSocket dono taraf live. SSE server → client stream.
