Advice: the 'add experience column' coding question seems to be very common with him so certainly do practice that, he also repeats his questions so go through the same questions of his in this spreadsheet and youll do just fine, you got this!

What database have you used

Times asked 1
Official solution

SimpleSQLite file-based DB — setup easy, MAD1 ke liye perfect. Production heavy traffic pe Postgres better.
Example

SQLALCHEMY_DATABASE_URI = 'sqlite:///app.db'
```

Change Code to reflect appointments which are only completed and not all appointments (I was on as in dashboard at that time so changed that part only)

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; }
```
Viva tipDevTools se pehle try, phir file mein permanent change.

Advice: If you download the project, the checksum won't be done. Open github to show repository. Start app and start vs code. No need to formalis the flow, the viva examiner will ask you to show functionalities one by one.

Diff bw get and post

Times asked 1
Official solution

SimpleGET data read/show karta hai (idempotent). POST create/submit karta hai (form).
Example
```
@app.route('/login', methods=['GET', 'POST'])
def login():
    if request.method == 'POST':
        # validate + session
        ...
    return render_template('login.html')
```
8
Can we send data through get

Times asked 1
Official solution

SimpleGET data mangta hai (read), POST data bhejta hai (create/submit).
GETURL mein dikhta hai, bookmark ho sakta hai, browser back/refresh safe hai, data URL query mein jaata hai. Search, page open, login form dikhana.
POSTbody mein data jaata hai, URL mein password nahi dikhta, refresh pe dubara submit ho sakta hai. Login, register, form save.
Example
# page dikhana
```
@app.route('/login', methods=['GET', 'POST'])
def login():
    if request.method == 'GET':
        return render_template('login.html')
    # POST: form submit
    email = request.form.get('email')
    ...
```
GET se theoretically data bhej sakte ho (?q=flask), lekin create/update ke liye nahi use karna — data log/history mein save ho jaata hai, length limit hoti hai.
HTML form default GET hota hai; method='POST' likhna zaroori hai login/register pe.
9
Request.form and request.args

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

HTTP Methods. Where is only GET request used in your routes?

Times asked 1
Official solution

SimpleHTTP verbs REST ke tools. Methods HTTP ke hain, REST unhe convention se use karta hai.
GET read cacheable. POST create payload. PUT replace. PATCH patch. DELETE remove.
GET exists bina REST ke bhi — browser address bar.
HTTP verbs + status REST ki zabaan. GET read, POST create, PUT replace, PATCH partial, DELETE remove. GET typically no body.
Status: 200 OK, 201 created, 202 accepted (Celery task), 400 bad input, 401 no/bad token, 403 role nahi, 404 missing, 409 conflict (double book), 500 server.
AJAX/fetch page reload nahi. SPA poori isi pe. Postman se bina Vue ke API prove karo — examiner pasand.
Example
```
GET /api/venues
POST /api/venues
PUT /api/venues/1
DELETE /api/venues/1
```
Project example: resources.py methods list. Postman 4-5 calls.
Viva tipGET typically no body (cacheable). POST/PUT/PATCH haan payload. PUT idempotent, POST nahi.
