What is meant by stateless

Times asked 1
Official solution

SimplePehle 1-line definition, phir apne MAD1 project mein file dikhao, phir chhota example.
Suggested flow1) Concept kya hai?
2) Mere code mein kahan?
3) Example / demo
4) Edge case
Example
```
# related file: models.py / routes / template
# formula: request → check/auth → DB → render/redirect

Suggested flow1) Classes list karo
2) Har table ka kaam 1 line
3) Relationships (1-M / M-M)
4) Constraints (unique, nullable)
Example
```
class Lot(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(80), nullable=False)
    spots = db.relationship('Spot', backref='lot', lazy=True)
```

asked about http methods, use of name in form, what will happen if we try to submit method='GET'(ans - we get that value in url) & how will we retrieve it in backend(ans - request.args.get('name')), after i told its value will be in url then she asked me to write & show how the url will look like 💀.

Told to open app.py, then whats the use of secret_key, i imported migrate so asked about that module what it does, gave a situation suppose 2 users already exists & u used migrate & added 2 new columns using migrate then what will the prev 2 users value contain in new columns? (ans - NULL, ans are very simple so dont get panicked with length of que 😊), whats __name__='__main__', whats is session what is session.clear(), she asked to open route where student apply for apps, i opened apply route, she asked for creating apps u r using drive id & student id so i can see u r passing drive id so from where u r getting student id?(ans - from session), then after this she finally wrapped up.😊 Finally at end we had a small conversation about my career like what im interested in, r u doing this degree standalone, she also gave career advice coz i was nervous during viva, she was very friendly she may give hint if u r stuck somewhere & till now it was amazing experience during this viva. 😊

At very first after copying venv, i was setuping migration stuff during that time proctor asked me whats the use of that commands which u r writing like python -m flask db init, python -m flask db migrate -m "ini commit", python -m flask db upgrade.

```

Demo & told to show all functionalities during that time he asked me the steps & i did exactly how sir told like create this do that do this (basically he wanted to see whether all core stuff works or not & also the edge points), asked about search func but i forgot to add that 🥲so i told sir but i know the logic how it works, asked to explain the drive model & relationships im using(i used back_populates but may ask for backref also & types of relationships), during explaining i volunteerily explained about ORM(sqlalchemy & how it works & benefits, say everything what u know related to particular topic unless he interrupts to consume bit time but be genuine), whats http stateless(ans - each request is independent), whats MVC. (coding part)

Times asked 1
Official solution

Simplebackref reverse attribute auto banata hai. back_populates dono sides explicitly naam dete ho — clearer.
Example
```
# backref
spots = db.relationship('Spot', backref='lot')
# spot.lot available

# back_populates
spots = db.relationship('Spot', back_populates='lot')
# Spot.lot = db.relationship('Lot', back_populates='spots')
```

He remembered when i told i may know the logic of search func as i havent implemented, finally he asked me to open notepad & told to write frontend part(using form) & also told to write backend(the route part) 💀 but somehow managed!!, asked if used get method then how will retrieve that in backend (request.args.get('name')), i was writing but in between he asked alright say me the logic coz i think he already knew i know the logic, so i told like i'll filter out by role & ilike & told exact code orally so he was satisfied, asked if form action url & route url mismatch then what will be result, asked template renders serverside or client side (i think it should be server side coz jinja is dynamic & html part will render on client side). finally sir told i will wrap it up here, viva went moderate 🥲

```

Advice: Proctor was calm & patient but seeing him seems sir was tired (may be) but overall went gd havent much interrupt during explaining 😊, So be calm n' chill, say as much u know related to topic they ask, along with viva 1 prep for viva 2 as well coz many prac concepts overlap so it will help, BEST OF LUCK 😊👍
