in app.py if we remove __name__=="__main__" will the project run?

Times asked 1
Official solution

SimpleLive UI change: relevant CSS/HTML template kholo — color, margin, flex, bootstrap class. Save + hard refresh.
Example
```
/* button red */
.btn-primary { background: red; }

/* center navbar item */
.navbar { justify-content: center; }
```

explain async and await

Times asked 1
Official solution

Simpleasync function promise return karti hai. await us promise ka result wait karta hai — callback hell kam.
Example
```
async function loadLots() {
  const res = await fetch('/api/lots');
  const data = await res.json();
  return data;
}
```

Official solution

Viva tipFunction signature + 3-4 important lines + edge case.

I explained my app.py, __init__.py, models, in models she asked questions about backref, cascade, relationships (and questions were asked on brief like how it works, what other thing can be used instead of this, where is it implemented in your app)

Official solution

Simpledb.relationship se object graph: lot.spots, booking.user. backref reverse side auto deta hai.
Example
```
spots = db.relationship('Spot', backref='lot', cascade='all, delete-orphan')
```

then she moved to coding part where she asked me to add a field in the admin navbar, that shows location and staff name of all the treks, I kept it very simple then she asked me to make it look clean and add some bootstrap in it coz I didn't

Official solution

SimpleLive coding: notepad/editor mein chhota Flask route / Jinja loop / model field. Calm raho, run karke dikhao.

Advice: She is calm and sweet asks many questions to test if you have really done all the work by yourself or not but gives time to think be prepared, you need to know everything that's done in your app

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')
```

write model code

Times asked 1
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)
```
