coming back to theory:

Times asked 1

Official solution

SimpleTheory = concepts: ORM, MVC, auth vs authz, Jinja inheritance, sessions. 1-line def + project example.
11
-http methods used in your project, and talk about them

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.
12

-other theory questions from this sheet.

Times asked 1

Official solution

SimpleTheory = concepts: ORM, MVC, auth vs authz, Jinja inheritance, sessions. 1-line def + project example.

Advice: take your time, but make the code modification questions work. my viva was for a full hour because I frequently ran into errors 😭 but the proctor wont pressurise you to speed up. he just observes whatever we are doing. I was mainly tensed in the code modification round but I could implement whatever was asked, so I guess you just have to try and make things work. if you run into errors, try to explain why they occur rather than panicking. the proctor was ok, he was not very rude or didnt interrupt me when i was speaking.

    return redirect(request.url)
if User.query.filter_by(email=email).first():
    flash('Email taken')
```

Advice: Overall, the examiner asked many cross-questions while I was explaining, so expect an interactive viva rather than a one-way presentation.

Advice: Like he was nice, silently observing everything, you'll have to ask him and not wait for him if you are stuck somewhere, really clear with what he wants to see, just know your code and logic should be clear, like in the coding question, I was confused how to change the color?? that was my viva pressure and now it feels like it was easy question, and I messed up!! Try not to be scared and get tunnel visioned, relax simple things will be asked, just answer and if you cannot it's ok!! DO NOT BE SCARED like me, viva is not like an exam it's just there for them to see how much you UNDERSTAND YOUR CODE!! just do that and you'll easily PASS
