Explain url_for and redirect.

Times asked 1
Official solution

Simpleredirect dusre URL pe bhejta hai. flash one-time message session mein rakh ke next page pe dikhata hai.
Example
```
flash('Login successful', 'success')
return redirect(url_for('user.dashboard'))
```
3
What is put and patch functions.

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.

Explain the HTML form used.

Times asked 1
Official solution

SimpleORM = Object Relational Mapping. Tables → Python classes. Raw SQL kam likhte ho.
Example
```
class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(120), unique=True)

User.query.get(5)  # SELECT ... WHERE id=5
```

Advice: 1. Show your id, GitHub repo and mention if you are doing checksum or downloading from the submission portal. 2. Show your demo and if asked explain your code.

Times asked 1

Official solution

SimpleCode explain formula: input kya aaya → auth/validation → DB change → response/UI.
Viva tipFunction signature + 3-4 important lines + edge case.

Advice: He's super chill, He emphasized on application demonstration and its functionality, but also asked basic question which were already there in the VIVA PYQ. Just focus on the code logic, understand it properly. VIVA-1 is super easy, you just need to understand the logic behind the code. and try to explain the logic behind the code while showing the demonstration. For example while adding an entry during the demonstration, explain where it is added, how it is added, and what is used in the whole process from clicking a button to the end of process. It's basic, but only if you know the LOGIC
