Then he asked me to show it in the terminal, which is simply going to the app, and try accessing the users with the url without giving the credentials. But I was just very much flabbergasted by the questions because I did not expect the questions to be like this and prepared for something like make changes over here and show me how will you implement this.

(coding part)

Simplebackref reverse attribute auto banata hai. back_populates dono sides explicitly naam dete ho — clearer.
Example
```

# 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 🥲

Official solution

Simplemodels.py = har table ki class: columns, PK/FK, relationships. Yeh Model layer hai.
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)
```
