    Times asked 1
    Official solution

    SimpleMAD2 orchestra: Redis, Flask, Vue, worker, beat — 5 terminals.

    Ports: Flask 5000, Vite 8080/5173, Redis 6379. CORS isliye.

    Order: Redis first. Worker bina Redis fail. Beat bina worker queue bharti.

    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

    redis-server
    flask run --port 5000
    npm run serve
    celery -A app.celery worker -l info
    celery -A app.celery beat -l info

    Project example: README local_run. Dikhao 5 processes + browser two roles.

    and asked the difference between put and patch in the middle
    Times asked 1
    Official solution

    SimplePOST naya janam (har baar naya id). PUT poori photo replace. PATCH sticker chipkao.

    POST create, not idempotent. PUT full update, idempotent. PATCH partial.

    POST ki jagah PUT se REST semantics toot. GET typically no body.

    CRUD map: POST create, GET read, PUT/PATCH update, DELETE delete.

    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

    POST /api/venues
    PUT  /api/venues/1   {all fields}
    PATCH /api/venues/1 {only name}

    Project example: POST /api/venues create. PUT /venues/1 saari fields. PATCH sirf name.
