Anish Phadke MAD1

he seemed very rude by his tone right from the beginning. After I initially explained my entire project in about 20 mins, I asked him if there was anything I missed out and he didn't even respond. So, I continued with the demonstration. After about 5 minutes, he asked to explain the models.py part (which I had already explained in detail). Overall, he didn't reciprocate much during the entire viva which made me feel like he was not even present or dissatisfied by my answers. At the end, surprisingly, he said that I explained very well and he left the meeting saying 'Thank you'. The entire viva lasted for 30 mins.

Questions remembered
  1. download your project from the portal and explain
  2. explain the database and models.py line by line
  3. elaborate the use of each and every library used by you
  4. demonstrate the core functionalities
Sheet response MAD1

He only wants you to explain each and every line of the code in an interesting manner. I was the one talking continuously for over 30 minutes in the entire viva. He was chill. Just know every line of your code, and speak as much as you can. All the best !

Questions remembered
  1. - Show ID
  2. - Either download from submission or run checksum
  3. - Asked to present my project
  4. - Asked to elaborate my entire code line by line
  5. - asked me if flask can return boolean type ? (i said it will throw error if sent directly, but we can wrap it in str() for example. He said Perfect !)
  6. - asked what's JSON ?
  7. - no code changes.
  8. - Ended in 33 mins
Sheet response MAD1

  2. Explain the complete Code?
  3. Change the Back Ground color of the web application?
  4. How to send data from client to server?
  5. Can flask end point send the Boolean type?
Sheet response MAD1

He was somewhat rude and uninterested right from the moment he joined the meet. As if someone was forcing him to take the viva.

Cannot predict the behaviour of the examiner from this sheet. They behave differently with different students at different times. Maybe he was annoyed that I had hijacked his lunch hour.

But he was patient. Did not interrupt. Gave time to figure out things when I got stuck once or twice.

He wants detailed explanation. So explain everything about your app in complete details right from the start. Consume as much time as possible. Then he'll not bother to ask further questions.

Practice the code changes that he asks, from this sheet. He always asks to do the same styling changes.

Questions remembered
  1. LEVEL 2 VIVA
  2. Do checksum and paste in the meet chat
  3. Start the intro of the app
  4. Interrupted few minutes later and said 'after you complete the intro, explain all the code line by line. I'll be back from the restroom. Continue, I'll be listening.'
  5. I explained the whole app in detail in a single flow (including the models) and also explained the code (be it backend or frontend) along with the GUI for some important and complex features.
  6. When I had finally reached the API, he stopped me after few seconds and made me change background colour of the login page to red, and that of the input boxes to green.
  7. When I did it successfully, he said okay great that's it from my side and ended the meet immediately. Didn't bother to hear or respond to my 'Tysm Sir.'
  8. That's it. No questions asked about project or theory.
  9. I had consumed 40 minutes of his time with my explaination. So he didn't go for any questions ig.
  10. Lasted for 45 mins.
Sheet response MAD1

Honestly, great proctor! he motivated me for my last answer and kept telling me good after my responses. Just stay calm, be polite and explain your app in detail. If he thinks you know what you're doing, he won't ask you to code most likely

Questions remembered
  1. - asked me to do checksum
  2. - asked me to present my app first
  3. - can flask return a boolean value?
  4. - what did I use to style my app? When I answered Bootstrap, he asked what's better CSS or Bootstrap

    Probably the most patient and most nice proctor i have ever had in all subjects. Minimal implementation that too UI and Colours only. But you have to have good knowledge on your project and know what code does what. That should be enough. if you know what functions are in your files, that is it. Nothing else. Just demo wlakthrough and 10 minutes of simple questions. All the best

    Times asked 1
Advice: Very calm and supportive proctor. He first explains the complete viva process, so don't panic. Keep your project ready because he asks for a complete demo followed by a detailed code explanation. Explain your project confidently without waiting for interruptions, as he mostly listens. Know your backend code well, especially authentication, JWT, Redis, Celery, and your project flow. Revise common theory questions like browser storage, template inheritance, Flask endpoints, and authentication vs authorization. If you explain your project clearly and confidently, the viva goes very smoothly.

Advice: - he will not speak very much ... You just have to go on explaining. He asked for a full demo (explain everything you app can do, demo background jobs like mail if possible), then asked to fully explain the code (both front end and backend, just detailed overview) - he's very chill, even though I wasn't able to answer the final question, he told me my approach was correct and then told me I did a good job 🙃🫪.

    All questions were from this sheet itself, so revise thoroughly before the viva and you will do well Overall the viva went well. Seems like the proctor wants people to be honest and straightforward with him. If one does that, he is flexible with everything. For e.g., I downloaded the MAD-1 project from the portal instead of MAD-2. The project didn't run and I was shitting bricks, but he was quite calm and gave me enough time to figure out that I have downloaded MAD-1 and not MAD-2. I corrected this error and he continued like nothing had happened.

Also, don't get panicked seeing the above response about him as RUDE, he is cool. You'll enjoy answering questions. He might roast you sometimes (like why you don't know this, but that you'll enjoy).So no need to worry. Just prepare the questions from sheets. (This is the 8th Response for this proctor).

    No live code changes for me.
    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'))
Advice: 1. Follow this sheet for your particular proctor. 2. Proctor might not speak for the entire duration of your demonstration and code explanation. He will just instruct you. 3. Practice explaining your code and take as much time as you can for that during the viva. Best of luck!👍

Advice: he seemed very rude by his tone right from the beginning. After I initially explained my entire project in about 20 mins, I asked him if there was anything I missed out and he didn't even respond. So, I continued with the demonstration. After about 5 minutes, he asked to explain the models.py part (which I had already explained in detail). Overall, he didn't reciprocate much during the entire viva which made me feel like he was not even present or dissatisfied by my answers. At the end, surprisingly, he said that I explained very well and he left the meeting saying 'Thank you'. The entire viva lasted for 30 mins.

Advice: He was somewhat rude and uninterested right from the moment he joined the meet. As if someone was forcing him to take the viva. Cannot predict the behaviour of the examiner from this sheet. They behave differently with different students at different times. Maybe he was annoyed that I had hijacked his lunch hour. But he was patient. Did not interrupt. Gave time to figure out things when I got stuck once or twice. He wants detailed explanation. So explain everything about your app in complete details right from the start. Consume as much time as possible. Then he'll not bother to ask further questions. Practice the code changes that he asks, from this sheet. He always asks to do the same styling changes.

    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) ZIP
    2) Extract
    3) Redis + venv + pip
    4) npm/vite
    5) flask + celery worker + beat

    5.What are the different ways data can be stored
    Times asked 1
    Official solution

    Simpledata() local diary. Store school notice board.

    Search query local. Logged-in user store. Persist: store + localStorage together.

    state vs data: similar concept, scope alag.

    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

    // local
data() { return { q: '' } }
// global
this.$store.state.user

    Project example: Login.vue local form fields. this.$store.state.user Navbar.

    Times asked 2
    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'))

{% extends 'base.html' %}
{% block content %}
  <h1>Home</h1>
{% endblock %}
Advice: Very calm and supportive proctor. He first explains the complete viva process, so don't panic. Keep your project ready because he asks for a complete demo followed by a detailed code explanation. Explain your project confidently without waiting for interruptions, as he mostly listens. Know your backend code well, especially authentication, JWT, Redis, Celery, and your project flow. Revise common theory questions like browser storage, template inheritance, Flask endpoints, and authentication vs authorization. If you explain your project clearly and confidently, the viva goes very smoothly.

    Write a code that in the database you see changes
    Times asked 2
    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.

    What are the different ways to store data in the browser
    Times asked 1
    Official solution

    Simpledata() local diary. Store school notice board.

    Search query local. Logged-in user store. Persist: store + localStorage together.

    state vs data: similar concept, scope alag.

    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

    // local
data() { return { q: '' } }
// global
this.$store.state.user

    Project example: Login.vue local form fields. this.$store.state.user Navbar.

    Difference between frontend and backend.
    Times asked 1
    Official solution

    SimpleFrontend user jo dekhta/click karta hai, Backend server logic + database.

    Frontend: HTML, CSS, Bootstrap, Jinja templates, thoda JS. Browser pe chalta hai.
    Backend: Flask routes, SQLAlchemy, session, validation. Python server pe.
    Data flow: form POST → Flask request.form → DB save → render_template/redirect → HTML dikha.
    MAD1 typical stack: Flask + Jinja + SQLAlchemy + SQLite + Bootstrap.

    Rate your app on the basis of how your viva went and justify it. some more theories ques which all were from this sheet only (it seems like he also have a sheet from which he is asking questions 🤡) As some others said above he is very rude; and HE IS. He tried to roast me twice during the viva lol. As the viva started he said " show me your ID card" in a very rude manner. He was impolite from the start. The trick is to pretend like you are very innocent and a good listener. Let him complete his entire question and wait for 1-2 sec and then respond also have a very serious face all the time like you are thinking about how to answer or solve his question I did this and in the end, he praised me for my good behaviour 🤡.

    What is caching?
    Times asked 23
    Official solution

    SimpleCache baar-baar DB/compute na karne ke liye result yaad rakhta hai.

    Browser cache, Flask cache, Redis. Example: dashboard counts 30 sec Redis mein.
    Cookies alag (client data). HTTP 304 Not Modified bhi cache related.
    MAD1 mein optional. Scale poochhe to pehle indexes + cache, phir extra servers.

  7. 7
    What is AJAX?
    Times asked 4
    Official solution

    SimpleAJAX page reload ke bina server se data laata hai. Aaj kal fetch() + Promises.

    fetch('/api/users').then(r => r.json()).then(data => { ... })
    Promise: future value (pending/fulfilled/rejected). fetch Promise return karta hai.
    SPA (Vue): ek HTML, baaki routes JS se, partial update. MAD1 generally full page render (Jinja) — submit pe poora refresh.
    async/await Promise ka clean syntax.

  8. 8
    All questions were from this sheet itself, so revise thoroughly before the viva and you will do well Overall the viva went well. Seems like the proctor wants people to be honest and straightforward with him. If one does that, he is flexible with everything. For e.g., I downloaded the MAD-1 project from the portal instead of MAD-2. The project didn't run and I was shitting bricks, but he was quite calm and gave me enough time to figure out that I have downloaded MAD-1 and not MAD-2. I corrected this error and he continued like nothing had happened.

    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>

    template inheritance
    Times asked 4
    Official solution

    Simpleextends poora layout inherit karta hai, include chhota piece insert karta hai.

    extends: child page base.html ka structure use karti hai, blocks override karti hai. Ek hi parent.
    include: navbar.html / footer.html jahan chaho insert. Kai baar use ho sakta hai.

    base.html:

    {% block content %}{% endblock %}

home.html:
{% extends 'base.html' %}
{% block content %}<h1>Home</h1>{% endblock %}

{% include 'navbar.html' %}  → navbar har page pe

    Fayda: header/footer ek jagah, change once — saari pages update. MAD1 mein almost har project use karta hai.

  13. 13
    lifecycle hooks
    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.

    mutations and actions
    Times asked 2
    Official solution

    SimpleMutations sync diary entry. Actions async kaam phir diary.

    Direct state mutate action se Vuex 4 discouraged. Devtools time-travel mutations.

    Purpose of Actions: API, phir commit. Purpose of Mutations: state change one place.

    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: action fetchVenues → commit setVenues. Mutation sirf array replace.

  16. 16
    task queue and message queue
    Times asked 2
    Official solution

    SimpleMessage queue generic. Task queue (Celery) specifically 'yeh function chalao'.

    Redis list FIFO. Priority extra queues.

    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: Celery is task queue on Redis broker.

  17. 17
    what is dos -
    Times asked 2
    Official solution

    SimpleDenial of Service flood/expensive queries se down. Rate limit, captcha, scale.

    Course: validation, indexes, cache. Not full WAF.

    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.

    Project example: Don't allow unbounded export without auth.

  18. 18
    opaque request
    Times asked 2
    Official solution

    SimpleOpaque request/token: andar ka structure client ko meaningful nahi — bas string id. Server pe map hota hai. JWT transparent claims dikhata hai.

    -redis
    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.

    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.

    SimpleAJAX = page reload ke bina server se baat. Technique ka naam, library nahi.

    Purana XMLHttpRequest. Aaj fetch() / Axios. Vue SPA poori AJAX pe chalti hai — JSON aata, v-for render.

    AJAX ≠ jQuery. Fetch native API. Axios library interceptors ke saath.

    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

    const res = await fetch('/api/venues')
const data = await res.json()

    Project example: mounted() mein fetch('/api/venues') — yeh AJAX hai.

    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.

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

    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!')

    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')

    Vuex RAM refresh gayab unless rehydrate LS.

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

    Authentication: login. Username + password hash check. Success pe JWT/session. Galat credentials = 401.
    Authorization: uske baad role. Admin hi venue/lot delete kare, student nahi = 403 (logged in ho, allowed nahi).

    MAD2: POST /api/login = authentication. @jwt_required identity. @roles_required('admin') ya Vue v-if="isAdmin" = authorization. Frontend hide sirf UX — asli deny backend pe.

    Official solution

    SimpleFrontend validation UX ke liye, Backend validation security ke liye. Dono chahiye, backend zyada important hai.

    Frontend: HTML required, minlength, JS/regex. User ko turant error dikhta hai. Bypass easy (DevTools / Postman).
    Backend: Flask route mein checks. Asli security yahi hai. Hacker frontend skip karke POST bhej sakta hai.

    Show validation implementation in your code.

    Official solution

    SimpleValidation galat data rok ti hai — frontend turant, backend must.

    Frontend: required, min='18', maxlength='8', pattern='(?=.*[A-Z]).{8,}'
    Backend example:

    pwd = request.form.get('password','')
if len(pwd) < 8 or not re.search(r'[A-Z]', pwd) or not re.search(r'[0-9]', pwd):
    flash('Weak password')

    Haan, regex se password rules ho sakte hain.
    Age 18-99, date >= today, slots <= 30 and > 0, confirm password == password, email '@' .
    Duplicate username: User.query.filter_by(email=email).first() or unique=True catch IntegrityError.
    Past date: if date < date.today(): reject. Negative slots: if slots < 0: reject; book pe available > 0 check.

    What is Flask?
    Times asked 6
    Official solution

    SimpleFlask Python ka micro web framework hai — routes, templates, request/response handle karta hai.

    from flask import Flask
app = Flask(__name__)
@app.route('/')
def home():
    return 'Hello'
app.run(debug=True)  # default port 5000

    __name__ se Flask ko pata chalta hai templates/static kahan se load karni hai. Hataoge to resource paths toot sakte hain.

    Faydesimple, flexible, MAD1 syllabus. Nuksaan: bade features (admin, auth) khud jodne padte hain.

    app.run() development server start karta hai. Production mein gunicorn/waitress.

    Difference between Python HTTP and Flask HTTP methods.
    Times asked 1
    Official solution

    SimpleHTTP methods batate hain request kya karna chahti hai. Common: GET POST PUT PATCH DELETE.

    GETread/fetch. Safe, URL se. Page kholna, search.

    POSTcreate/submit. Form, login.

    PUTpoora replace/update. Idempotent.

    PATCHpartial update.

    DELETEhataana.

    HEAD: sirf headers. OPTIONS: CORS preflight.

    Flask: @app.route('/x', methods=['GET','POST'])
    Agar methods na likho to default sirf GET.
    HTML form native sirf GET/POST. PUT/DELETE JS/fetch ya hidden _method se.
    GET se data fetch ho sakta hai, create nahi karna chahiye. POST se theoretically fetch ho sakta hai lekin cache/semantics galat.
    DELETE fetch ke liye nahi. GET POST ka kaam officially nahi karta — side effects GET pe mat rakho.

    How is data sent from client to server?
    Times asked 1
    Official solution

    Simple flow: Browser → Route (controller) → Model/DB → phir template (view) → Browser.

    Submit example:
    1) HTML form POST /register, name='email'
    2) register() request.form.get('email')
    3) User(email=...) ; db.session.add; commit
    4) redirect dashboard
    5) dashboard query + render_template
    6) Jinja {{ user.email }} / {% for %}

    GET search: /search?q=flask → request.args.get('q') → filter ilike → template list.
    JSON API: jsonify, frontend fetch().

    Official solution

    SimpleAJAX page reload ke bina server se data laata hai. Aaj kal fetch() + Promises.

    fetch('/api/users').then(r => r.json()).then(data => { ... })
    Promise: future value (pending/fulfilled/rejected). fetch Promise return karta hai.
    SPA (Vue): ek HTML, baaki routes JS se, partial update. MAD1 generally full page render (Jinja) — submit pe poora refresh.
    async/await Promise ka clean syntax.

    Modal: popup overlay. Bootstrap: data-bs-toggle='modal' data-bs-target='#id'.
    Flash hide: setTimeout se alert remove. Form submit confirm: onsubmit='return confirm(...)'.

    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'))

    Git distributed: har developer ke paas poori copy (commits) hoti hai. Central GitHub sirf remote hosting hai, lekin Git ka model distributed hai.
    SVN centralized: bina server ke history nahi.

    Commands: git status (kya dirty hai), git branch / git checkout -b feature (nayi branch), git rm --cached file (track band, file rahe).

    Difference between Cell Padding and Cell Spacing.
    Times asked 3
    Official solution

    Simplecellpadding cell ke andar gap, cellspacing cells ke beech gap.

    cellpadding: text aur cell border ke beech khali jagah (andar).
    cellspacing: do cells ke beech khali jagah (bahar).

    Old HTML: <table cellpadding='10' cellspacing='5'>
    Modern CSS:
    td { padding: 10px; } /* padding */
    table { border-spacing: 5px; } /* spacing */

    border-collapse: collapse spacing hata deta hai, borders mil jaate hain.

    Difference between url_for() and redirect().
    Times asked 2
    Official solution

    Simpleurl_for sirf URL string banata hai, redirect us URL pe browser ko bhejta hai.

    url_for('home') → '/home' (function name se URL nikalta hai)
    redirect(url_for('home')) → browser ko /home pe le jaata hai

    Example

    return redirect(url_for('dashboard'))  # sahi
return redirect('/dashboard')         # hardcode, route change pe toot jaayega

Agar redirect se url_for hata do to khud path string dena padega: redirect('/dashboard').
Agar url_for('home') ko url_for('home_page') kar do aur home_page naam ka function nahi hai to BuildError aayega.

    url_for ko function ka naam chahiye, URL path nahi.

    SimpleJSON = JavaScript Object Notation — data exchange ka text format.

    {"name": "Ram", "age": 20}
    APIs, localStorage, Chart.js data. Python dict ↔ JSON.
    Structured data: tables, fixed schema (SQL). Unstructured: images, logs, free text. JSON semi-structured.
    SQL structured relational. Mongo unstructured/document.

    Can an API return a Boolean value?
    Times asked 1
    Official solution

    SimpleAPI = Application Programming Interface — do systems predefined rules se baat karti hain. REST API HTTP + JSON use karti hai.

    Controller/route HTML bhi return kar sakta hai. REST API generally JSON return karti hai, frontend alag ho (Vue/Postman).

    Example

    @app.route('/api/users/<int:id>')
def get_user(id):
    u = User.query.get_or_404(id)
    return jsonify(id=u.id, name=u.name)

    MAD1 HTML apps mein 'API' kabhi-kabhi routes ko hi keh dete hain. Agar Vue nahi to bolo: server-rendered Flask, JSON APIs optional.
    Boolean return: technically jsonify(True) ho sakta hai, lekin meaningful JSON object better. Flask view None return kare to error.
    Test: Postman se GET/POST.
    Parsing: request.get_json() body se, request.args query se.

    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 }}

    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'))
