Sheet response MAD1

Keep your theory strong, be through with routes, models (db), and flask sessions.

The examiner is a bit strict. Not intimidating enough to snatch your soul, but not friendly too.

He won't help you. You are either on your own, or he'll explain the stuffs which you couldn't answer.

  3. * First, he told me to explain my folder structure
  4. * Then he was watching my model.py code and asked me about a one-to-one relationship and how I would do a one-to-one relationship from one-to-many.
  5. * Why did you use both a foreign key and db.relationship in a table.
  6. * diff between db.relationship and foreign key
  7. * How you control the error; he said about flash messages. I told him that I didn't use flash in my project. Then
  8. I told I will write the error message and explained how the error part is working for my project in app.py.
  9. * He asked me about what 402 error code mean(I don't know the answer, itna error code pdha tha like 200, 302,302,400,401,403,404,500, but usne vhi pucha jo mujhe nhi pta tha)

  14. * He told me to write the code in Notepad: write a code which create or add user in the database. I asked him about the register route, he told me it's on you. Here I wrote my entire register route in Notepad.
  15. * Finally, he told me to show the demo of your project.
  16. * At last, he told me that your knowledge of the error part is not enough; you should work on that, bcz in industries, we should handle error efficiently. You are able to write the code, and your UI is good. Best of luck for your MAD2.

He is nice , patient and gives time to try and explain. He will also let you ask and correct you where u get wrong. Don't rely on questions here , U need to have a proper understanding of the logics u put behind the project , For me i wasnt able to answer a lot of questions and he simply said me practice and to actually make the project next time for MAD2.

    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.

    Diff between http and HTTPS and how is it more secure
    Times asked 1
    Official solution

    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.

    Project example: Dev localhost http. Production https:// + cert.

    3.Difference between Action and Mutation
    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.

    5.Difference between ref and reactive
    Times asked 1
    Official solution

    Simpleref() wrap .value, primitive. reactive() object proxy. Destructure ref toot sakta.

    Options API this.x. Composition choose one style.

    Component = reusable UI block (Navbar, Card). Props parent→child data, emit child→parent event. Slots parent HTML inner content.

    computed cache + reactive derive (filtered list). watch side-effect (query change pe API). methods events. ref() primitive, reactive() object. Vuex/Pinia global store; localStorage persist, store nahi.

    SFC: template + script + style ek .vue file. Parent-child exam favourite: list parent, row child :item + @delete.

    Example

    const count = ref(0)
count.value++
const form = reactive({ email: '' })

    Project example: If Options only, bolo nahi use, Options data().

    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!')

    SimpleCSS look. Selectors element .class #id. Box model flex grid.

    Inline vs internal vs external. Specificity inline high.

    Look: Bootstrap utility classes (margin m-3, flex, grid) ya khud CSS. Responsive = media query / Bootstrap breakpoints se mobile.

    Vue scoped style leak nahi. :class binding. Examiner colour/button live change maange to DevTools nahi, source class dikhao.

    CSS ≠ Bootstrap. Bootstrap CSS+JS framework. Inline style last resort.

    Example

    .btn { background: green; }

.my-3 { margin-top+bottom }

    - Redis: Server-side or client-side?
    Times asked 1
    Official solution

    SimpleRedis server-side daemon hai. Browser usko directly nahi bolta.

    Flask/Celery redis-py se localhost:6379. Client-side localStorage alag.

    Examiner confuse kare: 'Redis frontend?' — nahi, backend process.

    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: redis-server terminal. Vue sirf fetch Flask.

    - Explain Celery initialization (celery init)
    Times asked 1
    Official solution

    SimpleCelery instance, broker URL, @celery.task, worker command, Beat schedule.

    DB use karte waqt with app.app_context():. .delay() JSON-serializable args.

    Examiner files: celery.py / tasks.py / config beat dict / README commands.

    Celery Python ka distributed task queue — HTTP request ko 10s email/CSV ke liye mat rokna.

    Flow: Flask .delay() → Redis broker → Worker execute. Beat alag process hai (clock): crontab padhke due time pe queue mein daalta hai. Beat khud mail nahi bhejta; Worker haath hai.

    MAD2 typical: daily reminder (Beat), monthly report (Beat), user Export CSV (button, Beat nahi). JS async/await browser event loop hai, Celery server-side process — mix mat karo.

    Demo: tin terminals — redis-server, celery worker, celery beat — plus Flask. MailHog :8025 inbox. Result backend se task SUCCESS poll optional.

    Example

    celery = Celery(__name__, broker='redis://localhost:6379/0')
@celery.task
def ping():
    return 'ok'

    Project example: jobs.py daily_reminder, monthly_report, export_csv. config.py broker.

    What is an Object in Vue why used. JS object.

    SPA = ek HTML, Vue Router se views, full reload nahi. MPA = MAD1 Jinja har URL naya HTML.

    Vue Router: routes array, router-view, router-link, meta.auth + beforeEach guard. Dynamic /venues/:id → $route.params.id.

    Is Redis server-side or client-side?
    Times asked 1
    Official solution

    SimpleRedis server-side daemon hai. Browser usko directly nahi bolta.

    Flask/Celery redis-py se localhost:6379. Client-side localStorage alag.

    Examiner confuse kare: 'Redis frontend?' — nahi, backend process.

    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.

    @cache.memoize arguments se key banata hai — get_user(5) aur get_user(9) alag cache.

    Prefix clash se galat data mil sakta hai. Dono ka timeout same idea hai. Invalidation: delete_memoized(fn, args) vs cache.delete(prefix).
