Models.py relationships classes

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')
```
2

App.py

Times asked 1

Official solution

SimpleRoutes/controllers URLs handle karte hain. app.py app banata hai, models.py data, templates/ views, static/ CSS-JS.
Typical structure:
app.py / __init__.py → Flask app, db.init, register blueprints
models.py → tables
routes.py / views → @app.route functions
templates/ → Jinja HTML
static/ → css, images
instance/*.db → SQLite
Ek route explain karne ka template:
1) URL + methods 2) Auth/role check 3) Form/query se data 4) Business rule (duplicate, slots) 5) db.session 6) render ya redirect
Example GET+POST same route: GET form, POST save.
Data HTML se: form name= → request.form. Data HTML ko: render_template(..., items=query).
Nayi .py file: import karke use karo, warna Flask ko pata nahi. Folder rename: imports/paths/templates check.
3
A jinja if else or loop

Times asked 1
Official solution

SimpleJinja for loop list render karta hai. loop.index, else branch empty list pe.
Example
```
{% for u in users %}

{% endfor %}
```

VCS (git)

Times asked 1

Official solution

SimpleVCS history track karta hai, Git ek distributed VCS hai.
VCS: kaun kab kya change kiya, rollback, branches. Example: Git, SVN.
Git distributed: har developer ke paas poori copy (commits) hoti hai. Central GitHub sirf remote hosting hai, lekin Git ka model distributed hai.
SVN centralized: bina server ke history nahi.
Commands: git status (kya dirty hai), git branch / git checkout -b feature (nayi branch), git rm --cached file (track band, file rahe).
Fayda: collaboration, backup, experiment branches, viva GitHub collaborator check.
Git ke bina bhi files rakh sakte ho, lekin history/merge nahi.

1. The proctor joined the session around 15 minutes late.

Times asked 1
Official solution

SimpleMAD1 mein usually session-based auth: login pe session['user_id'], har request pe verify.
Example
```
session['user_id'] = user.id
uid = session.get('user_id')
user = User.query.get(uid)
```
Viva tipSECRET_KEY set karo warna session insecure. logout pe session.clear().

3.Then she asked whether I wanted to perform checksum verification or download from the portal. I chose to download from the portal.

Times asked 1

Official solution

SimpleExaminer portal wala submitted ZIP chahta hai. Local extra changes mat dikhana.
Suggested flow1) Portal ZIP download
2) Extract
3) venv + pip install -r requirements.txt
4) flask run / python app.py

4.When I was about to run my app.py, she stopped me and asked to first show app.py and models.py.

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)
```

5.She then asked questions about database relationships used in the project.

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')
```

6.She gave a coding question: the database already has a User table with only a name field, and I had to explain how to add new data into it. She asked me to write the answer in a file named viva.txt.

Times asked 1

Official solution

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

7.Next, she asked: if there is a relationship between Student and Application, how will you fetch application data without writing an explicit query?

Times asked 1
Official solution

Example
```
spots = db.relationship('Spot', backref='lot', cascade='all, delete-orphan')
```

8.She asked me to explain the User model.

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)
```
9
10.She asked: if the Submit button triggers GET instead of POST, then where will the data be visible?

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')
```
10
11.Match the following question: redirect → /login, render_template → /login.html, url_for → login.

Times asked 1
Official solution

Simplerender_template Jinja HTML file ko data deke final HTML banata hai.
Example
```
return render_template('dashboard.html', user=user, lots=lots)
```
11
12.Another coding question (in viva.txt): write a route and HTML form where the user enters a name and on submit, the data is stored in the database.

Times asked 1
Official solution

SimpleLive Flask coding: chhota route likho, save, browser/curl se test. Syntax error terminal mein padho.
Example
```
@app.route('/ping')
def ping():
    return jsonify(ok=True)

@app.route('/even/<int:n>')
def even(n):
    return 'even' if n % 2 == 0 else 'odd'
```

2

Asked three theory questions

Times asked 1

Official solution

SimpleTheory = concepts: ORM, MVC, auth vs authz, Jinja inheritance, sessions. 1-line def + project example.
3

Like what is MVC

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.
4
And What is REST API

Times asked 1
Official solution

SimpleAPI = Application Programming Interface — do systems predefined rules se baat karti hain. REST API HTTP + JSON use karti hai.
Controller/route HTML bhi return kar sakta hai. REST API generally JSON return karti hai, frontend alag ho (Vue/Postman).
Example
```
@app.route('/api/users/<int:id>')
def get_user(id):
    u = User.query.get_or_404(id)
    return jsonify(id=u.id, name=u.name)
```
MAD1 HTML apps mein 'API' kabhi-kabhi routes ko hi keh dete hain. Agar Vue nahi to bolo: server-rendered Flask, JSON APIs optional.
Boolean return: technically jsonify(True) ho sakta hai, lekin meaningful JSON object better. Flask view None return kare to error.
Test: Postman se GET/POST.
Parsing: request.get_json() body se, request.args query se.
5

Diff btw put and patch

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.

Patternfilter query → template/JSON. Examiner jo entity bole us class ka naam use karo.

    return render_template('list.html', rows=rows)

JSON: return jsonify([{'id': r.id, 'name': r.name} for r in rows])
ID se: User.query.get_or_404(id)
Do filters: .filter(Drive.approved==False, Drive.title=='Data Scientist')
```
Join example: students jinhone blacklisted company ke drive pe apply kiya — join Application-Drive-Company.
PUT@app.route('/x/<int:id>', methods=['PUT']) + request.get_json()
url param display: @app.route('/show/<int:id>') return render_template('show.html', id=id)
Form → next page: POST values render_template('out.html', **request.form)
Count: return str(User.query.filter_by(is_blacklisted=True).count())
