sessions vs tokens

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

Times asked 1
Official solution

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

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

    email = db.Column(db.String(120), unique=True)

User.query.get(5)  # SELECT ... WHERE id=5
```

Theoretical questions:

Official solution

2
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.

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>

Vue CLI vs CDN

Times asked 2
Official solution

SimpleCDN = Vue script tag se, jaise pen drive. CLI/Vite = poori factory (SFC, npm, bundle).
CDN: no build, chhote apps, exam PC pe Node nahi to bhi chal. Weak: no .vue compile, 3rd-party cache, scale/team.
CLI/Vite: Single File Components, env, code-split, production dist/. Scalable.
Examiner 'which + why' — jo use kiya wahi justify, doosra naam rato mat.
Example
```

<script src="https://unpkg.com/vue@3/dist/vue.global.js"></script>

# Vite
npm run dev
npm run build
```
Project example: CDN: index.html unpkg vue. CLI: package.json, npm run serve / vite.
Viva tipCDN scalable large teams ke liye weak (no SFC compile, caching 3rd party). Examiner 'which + why' poochta hai — jo use kiya wahi justify karo.

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.
Viva tipFayde: easy, SFC, reactivity. Vs React: chhota learning curve. Vs plain JS: UI state auto-update.

Vue lifecycle

Times asked 2
Official solution

SimpleLifecycle = component ki zindagi ke stages. API call tab jab DOM ready ho — mounted.
created: instance bani, this data, DOM nahi. mounted/onMounted: page pe aa gaya — fetch, Chart.js, setInterval.
updated: data change ke baad. unmounted: cleanup (clearInterval) warna memory leak.
Dashboards onMounted isliye: canvas/API tab valid. created mein $el nahi.
Composition: onMounted(() => {}) setup ke andar.
Example
```
export default {
  async mounted() {
    const r = await fetch('/api/venues')
    this.venues = await r.json()
  }
}
```
Project example: Venues.vue mounted fetch list. Clock component unmounted pe interval clear.
Viva tipcreated: data setup, DOM nahi. mounted/onMounted: $el mil gaya — fetch yahi. Dashboards isliye onMounted use karti hain.

Asked to login route in notepad

Times asked 2
Official solution

Simple@app.route URL ko Python function se jodta hai. @ wala cheez decorator hai.
```
@app.route('/hello/<name>', methods=['GET'])
def hello(name):
    return f'Hello {name}'
```
Decorator function ko wrap karke extra behaviour deta hai (route register, login_required).
Endpoint generally function name. Path /hello/Ram.
<int:id> type converter — sirf integer. Bina converter string. ID chahiye to int safer.
methods=['POST'] only POST. Default GET.
functools.wraps custom decorator mein original function name/docs preserve karta hai.

Simplebackref reverse attribute auto banata hai. back_populates dono sides explicitly naam dete ho — clearer.

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

Celery

Times asked 9
Official solution

SimpleCelery = background naukri. HTTP request ko 10 second email bhejne ke liye mat rokna.
Distributed task queue: aap function ko abhi nahi, worker process mein later/retry/schedule pe chalaate ho.
MAD2 typical jobs: daily reminder mail, monthly HTML report, user-triggered CSV export.
Web request 200ms hona chahiye. 10,000 emails request thread mein = timeout. Worker alag CPU pe kaam kare.
Redis broker chahiye. Beat alag process schedule ke liye.
Example
```
@celery.task
def daily_reminder():
    for u in User.query.filter_by(active=True):
        send_mail(u.email, 'Book something today!')
```
Project example: User Export click → 202 Accepted. Worker CSV + email. Daily 6pm Beat reminder.
Viva tipWorker + Redis bina Beat ke user-triggered chalega. Scheduled jobs ke liye Beat bhi chahiye.

Redis

Times asked 6
Official solution

SimpleRedis fridge pe sticky note hai — poori kitchen (database) kholne ki zarurat nahi.
Redis in-memory key-value store hai. Data RAM mein rehta hai, isliye disk wale SQLite/Postgres se kai guna tez.
MAD2 mein Redis do kaam karta hai:
1) Cache — same venue/show/dashboard JSON baar-baar DB se mat nikaalo.
2) Celery message broker — Flask task queue mein daalta hai, worker uthata hai.
Source of truth database hi hai. Redis band ho to cache miss ho jaata hai aur Celery queue ruk sakti hai. Crash pe cache gayab ho sakta hai — isliye important data sirf Redis mein mat rakho.
Example
```
import redis
r = redis.Redis(host='localhost', port=6379, db=0)
r.set('venues', json.dumps(data), ex=30)
print(r.get('venues'))
```
Project example: GET /api/venues pehle Redis dekho. Miss pe SQLAlchemy query, phir SET with timeout. Celery worker Redis list se daily reminder uthata hai.
Viva tipCache ke liye db=1, broker ke liye db=0 rakhna smart hai taaki keys mix na hon. Viva mein redis-cli ping → PONG dikhana strong hai.

Vue directives

Times asked 3
Official solution

SimpleDirectives Vue ke special attributes — HTML ko superpower.
v-if/else/show, v-for, v-bind (:), v-on (@), v-model, v-html (XSS), v-cloak, v-slot.
:src = v-bind:src. @click = v-on:click.
Custom directives bhi (v-focus) — course basics kaafi.
Example
```
<p v-if="ok">Yes</p>
<li v-for="u in users" :key="u.id">{{ u.name }}</li>
<input v-model="email">
<img :src="url">
```
Project example: List v-for :key. Form v-model. Admin v-if. Image :src.
Viva tip: src ke liye v-bind:src ka shorthand. @click = v-on:click.
6
Authentication vs authorization

Times asked 5
Official solution

SimpleAuthentication poochta hai "tu kaun hai?", Authorization poochta hai "tujhe yeh kaam karne ki permission hai?"
Authentication: login. Username + password check karke prove karte ho ki tum genuine user ho. Success pe session/token milta hai.
Authorization: uske baad role check. Admin hi parking lot delete kar sakta hai, normal user nahi.
Example (Flask):
# Authentication
```
if user and check_password_hash(user.password, form_password):
    session['user_id'] = user.id

# Authorization
if session.get('role') != 'admin':
    abort(403)  # logged in ho, lekin allowed nahi
```
Project example: student login = authentication. Student admin dashboard nahi khol sakta = authorization.
Validation alag cheez hai (form sahi bhara hai ya nahi, jaise age 18+).
