Advice: Friendly examiner. Be ready to explain your project and make small code changes on the spot (e.g., adding a field or changing Bootstrap styles). Understanding your code is more important than memorizing definitions. And duration: ~30-35 minutes.

{% endfor %}
```

Advice: Please learn how to add/delete columns in db safely. Also learn how to pull and display the modifcations to final html. It's not a GPT's work. You only know your app, so learn to plug codes wherever necessary. Be respectful.....

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')
```

Some theory questions about Authorization vs Authentication, and what is CSRF

Times asked 1
Official solution

SimpleAuthentication: tu kaun hai? (login). Authorization: tujhe permission hai? (role check).
Example
```
# auth
if check_password_hash(user.password, pwd):
    session['user_id'] = user.id

# authz
if user.role != 'admin':
    abort(403)
```

Advice: Just don't panic, they will wait for you to think and do stuff. Make sure you know your code well enough to point to anything they ask for, and that you can make changes to the code on the spot like mentioned above Gluckk

Identify MVC in my app - which moved on to explain it by doing some action, like registering or adding a dept. or doctor. So, i described the MVC framework in action, going back and forth to code and browser.

Times asked 1

Official solution

SimpleMVC: Model=data (SQLAlchemy), View=Jinja HTML, Controller=Flask routes/business logic.
Flask loosely MVC follow karta hai — routes controllers, templates views, models.py models.
3
Code Change. Asked me to add an address field, in doctor's registration. So I had to add a new column in doctor's model for the database, a new form field, pass it on the route, and finally in the html. I had some jinja exceptions, which I quickly fixed but he never rushed me through.

Times asked 1
Official solution

SimpleJinja for loop list render karta hai. loop.index, else branch empty list pe.
Example
```
{% for u in users %}
  <tr><td>{{ loop.index }}</td><td>{{ u.email }}</td></tr>
{% endfor %}
```
4
Another Code Change had to do with changing minor text colors, what bootstrap class I'm using for that etc. __No more code changes__ For theory questions, I had to describe my database relationship in detail. I described I used "Usefield=False" for One-One relations, why i used "back_populate" instead of "back_ref"(He never asked me this, but I explained for clarity sakes and to dodge any further questions. Some explanation for keywords like, "redirect", "url_for", HTTP methods, "CSRF"(which I couldn't explain, I only knew this is used for security).

Times asked 1
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')
```

Advice: The proctor is very calm and gives you enough time to explain your thought process, kind of trusts you to speak for yourself rather than rapid fire questions. Please practice minor code changes, and learn about keywords, terminologies associated with the whole Flask based system.
