-asked what can be used to modify only the name of the doctor table without changing other columns, i said path http request, he asked then why is it not used here, i didn't know, he said since patch does not support flask html

Times asked 1
Official solution

SimpleFlask lightweight Python web framework — routes, request/response, templates. MAD1 ka backend yahi hai.
Example
```
from flask import Flask
app = Flask(__name__)

@app.route('/')
def home():
    return 'Hello'
```
Viva tipFlask micro hai: jo chahiye (DB, login, forms) khud jodte ho.

-difference between session.db and session storage

Times asked 1
Official solution

SimpleMAD1 mein usually session-based auth: login pe session['user_id'], har request pe verify.
Example
```

```
Viva tipSECRET_KEY set karo warna session insecure. logout pe session.clear().

SimpleJinja for loop list render karta hai. loop.index, else branch empty list pe.
Example
```

  <tr><td>{{ loop.index }}</td><td>{{ u.email }}</td></tr>
{% endfor %}
```

Advice: The questions were a bit unexpected for me. Sir asked me to make the file structure explanation quicker next time as he had to stop my explanation part before completing it to ask the viva qns and there was no time to complete the explanation and show demo in the end.

5.asked about the difference between Application Context and Request Context.

Times asked 1
Official solution

SimpleApplication context app-level data (config, db), Request context ek HTTP request (request, session).
Request ke andar Flask khud context push karta hai. Scripts/shell mein db query ke liye:
```
with app.app_context():
    User.query.all()
```
app.app_context().push() same, lekin with better (cleanup).
current_app proxy current Flask app ki taraf. Factory pattern mein import app cycle avoid.
Request context ke bahar request.form error dega.

7.Lastly, he asked about Cascade.

Times asked 1
Official solution

SimpleCascade parent delete pe children pe kya ho: delete-orphan related rows hata deta hai.
Example
```
db.relationship('Spot', cascade='all, delete-orphan')
```
Viva tipParking lot delete → uske spots/bookings policy clear bolo.

Advice: The examiner was chill and listened very carefully during the project demonstration. He asked me a lot of questions

Asked me diff Between PUT and POST.

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.
