Some CSS questions (basic)

Times asked 1
Official solution

SimpleVue = UI ka smart assistant. Data badlo, screen khud update. MAD1 Jinja har click pe naya HTML.
Progressive frontend framework. Components, reactivity, directives.
MAD2 SPA: ek index.html, Vue Router pages, Flask sirf JSON.
Fayde: easy, SFC, docs. Vs React: templates HTML-like, course sikhata hai. Vs plain JS: baar-baar DOM mat chhedo.
Example
```

<template>
  <h1>{{ msg }}</h1>
</template>
<script>
export default { data() { return { msg: 'Hello' } } }
</script>
```
Project example: Navbar.vue + views (Login, Dashboard). data() / setup() reactive. fetch APIs.

Explain flow of any one Flask route

Times asked 1
Official solution

```
13
request.args vs request.session vs request.json

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().
14
Flask handle files

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'
```

15

Debug mode

Times asked 1

Official solution

SimpleDebug: terminal traceback padho, print/logging, Flask debug, browser Network/Console, reproduce minimum steps.
16
Authentication vs Authorization

Times asked 2
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)
```
17
What is secret key

Times asked 1
Official solution

SimpleSECRET_KEY Flask ka secret jisse session cookies sign/encrypt hoti hain.
```
app.config['SECRET_KEY'] = os.getenv('SECRET_KEY', 'dev-key')
```
Iske bina session/flash unreliable ya insecure. Key leak = attacker session forge kar sakta hai.
Hardcode mat karo production mein — .env / environment variable. Flash messages bhi session use karti hain, isliye SECRET_KEY se related hain.
Hataane pe session kaam nahi / warning. Change karne pe purane sessions invalid.
18

-Store the age field in the database

Times asked 1
Official solution

Simpledata() local diary. Store school notice board.
Search query local. Logged-in user store. Persist: store + localStorage together.
state vs data: similar concept, scope alag.
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
```
// local
data() { return { q: '' } }
// global
this.$store.state.user
```
Project example: Login.vue local form fields. this.$store.state.user Navbar.

Explain the logic behind the admin search patient feature.

Official solution

SimpleSearch: form/query param → ilike filter → results template.
Example
```
q = request.args.get('q', '').strip()
lots = Lot.query.filter(Lot.name.ilike(f'%{q}%')).all()
```

Are foreign keys unique?

Times asked 1
Official solution

SimpleForeign key dusri table ke PK ko point karti hai — relationship banati hai.
Example
```
lot_id = db.Column(db.Integer, db.ForeignKey('lot.id'), nullable=False)
```

Advice: Be calm, don’t fumble over your words, and if you don’t know something, calmly say, “Sorry, I don’t know.” Make sure you know the logic of all the functions and can explain it articulately.

Diff 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.
