• Difference Between Backref and Back _populates

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')
```
4
• Difference Between 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.

def even(n):
    return 'even' if n % 2 == 0 else 'odd'
```

-Asked about db whether it is a class or object

Times asked 1
Official solution

Simple:class object/array/string dynamic CSS.
Purpose dynamic class. Error red.
Directives Vue ke special attributes hain — HTML ko superpower: v-if/v-show, v-for, v-bind (:), v-on (@), v-model.
v-if DOM se hataata/jodta. v-show sirf CSS display. Rare/permission: v-if. Bar-bar toggle: v-show. v-model two-way form. v-bind one-way JS→attribute.
:key v-for pe zaroori warna Vue galat reuse. v-html XSS. Secret UI ke liye sirf v-if kaafi nahi — API 403 bhi.
MAD1 Jinja server HTML. MAD2 yeh directives browser mein reactive.
Example
```
<div :class="{ 'text-danger': error, 'fw-bold': important }">Msg</div>
```
Project example: :class="{ 'text-danger': error }"

How did you implement authentication and authorisation in your project? Show the codes

Times asked 1

SimpleAuthentication: tu kaun hai? (login). Authorization: tujhe permission hai? (role check).

# authz
if user.role != 'admin':

Learn the concept of session well

Times asked 1

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().

# Spot.lot = db.relationship('Lot', back_populates='spots')
```

Advice: Read your entrie project thoroughly line by line before the viva. Any type of question based on your code may be asked. Very supportive and helps if you get stuck.

Flask loosely MVC follow karta hai — routes controllers, templates views, models.py models.

9)What is the flow of your Login Page.

Times asked 1
Official solution

SimpleLogin flow pehle poochta hai "tu kaun hai?", token milne ke baad har API pe wohi proof dikhate ho.
Authentication step: Vue form email + password JSON POST karta hai. Flask user dhoondhta hai, check_password_hash se prove karta hai ki tum genuine ho. Galat 401. Sahi pe JWT + role milta hai — yeh session/token hai.
Vue localStorage (ya cookie) mein token rakhta hai, dashboard pe router.push. Aage ki har fetch header: Authorization: Bearer <token>. @jwt_required identity check (authentication). @roles_required('admin') permission check (authorization) — logged in ho, lekin allowed nahi to 403.
Validation alag cheez hai: empty email, password 8+ — form sahi bhara hai ya nahi. Woh identity prove nahi karta.
Logout = client token delete + login page. Server blacklist optional. Password response JSON mein kabhi mat bhejo.
Example
```
# Authentication
@app.route('/api/login', methods=['POST'])
def login():
    u = User.query.filter_by(email=data['email']).first()
    if not u or not check_password_hash(u.password, data['password']):
        return jsonify(msg='bad'), 401
    return jsonify(token=create_access_token(u.id), role=u.role)

# baad ki APIs
# Authorization: Bearer <token>
if current_user.role != 'admin':
    abort(403)
```
Project example: Login.vue POST /api/login → token LS → interceptor. Student token se admin route = 403. Empty form = validation, galat password = 401.
Viva tipNetwork tab mein password body dikhega localhost pe — prod HTTPS. Response mein hash/password echo mat karo.

.navbar { justify-content: center; }
```
Viva tipDevTools se pehle try, phir file mein permanent change.

Advice: Calm & Listen to everything without interrupting. Any line you think you don't know enough about.. Copy paste and read the explanation in brief. Understand the flow of every route used . For example.. Backend request data from Frontend..User Provides data.. Provided goes to this logic ..now route ask database for the data.. These lines process the data.. Return line render_template (display or push the data to frontend) For Coding just know 1)Login Route 2) Input from One Page output on othet (Route+ template) 3) Display any particular data.. blacklisted user /completed trek (model.query.filter_by(<condition>).all()) 4) Change in CSS

Why we use if(__name__==__main__)

Times asked 1
Official solution

Simple
```
if __name__=='__main__' only when file run directly. Import pe nahi — app.run yahi. Remove import pe server start ho sakta.
```
Celery/tests import app without serving. Why used.
Flask Python micro web framework. Route decorator URL → function. MAD2 mein JSON API: request.get_json(), jsonify, JWT.
WSGI: server (Werkzeug) app ko call. if __name__ == '__main__' sirf direct run. Factory create_app() test/celery ke liye.
Blueprint/resources folders. @app.route vs MethodView. Debug=True viva local, prod nahi. CORS alag port Vue ke liye.
Project example: app.py bottom.
