```
17

* 2. Git and Version control

Times asked 1

Official solution

SimpleGit version control: commit history dikhao. VCS = Version Control System.
18
* 3. HTTP methods in REST API

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.

Then asked me to explain the search mechanism.

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()
```
5

ilike vs like

Times asked 2

Official solution

SimpleLIKE case-sensitive Postgres. ILIKE insensitive. SQLite LIKE often insensitive.
Search use ilike.
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: Venue.name.ilike(f'%{q}%').
Project example: Venue.name.ilike(f'%{q}%').

Advice: This proctor doesn't focus much on the code writing or code change in viva, only theoritical questions.

1.Diff btw id and class in html

Times asked 1
Official solution

Simple:class object/array/string dynamic CSS.
Purpose dynamic class. Error red.
Directives Vue ke special attributes hain — HTML ko superpower: v-if/v-show, v-for, v-bind (:), v-on (@), v-model.
v-if DOM se hataata/jodta. v-show sirf CSS display. Rare/permission: v-if. Bar-bar toggle: v-show. v-model two-way form. v-bind one-way JS→attribute.
:key v-for pe zaroori warna Vue galat reuse. v-html XSS. Secret UI ke liye sirf v-if kaafi nahi — API 403 bhi.
MAD1 Jinja server HTML. MAD2 yeh directives browser mein reactive.
Example
```
<div :class="{ 'text-danger': error, 'fw-bold': important }">Msg</div>
```
Project example: :class="{ 'text-danger': error }"
