Cascading in database, put and post difference and different http method

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.

5.What are different HTTP methods

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.
