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.

He stopped me and asked, how much AI have you used ?

Times asked 2

Official solution

SimpleSach % + kahan + kaise verify + kya seekha. Report se contradict mat.
Boilerplate vs business logic. Examiner process poochta. 'Sab ChatGPT' red flag.
Verify: docs, run, edge case. Seekha: CORS, JWT exp, beat vs worker.
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.
Project example: Jo number form/PDF mein hai wahi. Example file jo AI se start kiya, khud debug kiya.
Viva tipExaminer 'kya seekha / kaise check kiya' pe marks. 'Sab ChatGPT' red flag. Jo khud debug kiya woh story ready rakho.

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
```

Reasoning for my frontend design. - all dashboards using onMounted hook.

Times asked 2
Official solution

SimpleonMounted = Composition API ka mounted. setup() ke andar call.
Options API: mounted() method. Mix mat. Vue 3 dono chalte.
Lifecycle = component ki zindagi: created (instance, DOM nahi) → mounted/onMounted (DOM ready — fetch, Chart.js yahi) → updated → unmounted (clearInterval).
Dashboard API created mein isliye nahi ki $el/canvas missing ho sakta. Composition API: onMounted(() => {}) setup ke andar. Options: mounted() method. Mix mat.
Examiner 'konsa hook use kiya' — related .vue kholo, line padh ke bolo.
Example
```
import { onMounted, ref } from 'vue'
const items = ref([])
onMounted(async () => {
  items.value = await (await fetch('/api/items')).json()
})
```
Project example: script setup: onMounted(loadStats).

Celery configuration and how redis cache and celery are integrated with backend server.

Times asked 1
Official solution

SimpleRedis box hai, Celery us box se kaam uthane wala worker hai — same cheez nahi.
Redis: store (cache keys) + queue (broker lists).
Celery: Python library jo tasks define karti hai, .delay() se queue mein daalti hai, worker execute karta hai.
Dono localhost pe ho sakte hain. Alag Redis DB index use karo. Redis band = cache miss + Celery stuck.
Example
```
Celery: broker_url='redis://localhost:6379/0'
Cache:  CACHE_REDIS_URL='redis://localhost:6379/1'
```
Project example: export_csv.delay(user_id) Flask se. Worker Redis se task uthata hai, CSV+email. Cache alag keys venues.
Viva tipAgar possible ho to cache db=1, broker db=0 — keys mix nahi hoti.

How is user Authentication performed ? + RBAC demo.

SimpleRBAC = Role Based Access Control. Roles (admin/user) se permissions milti hain, har user pe alag list nahi.

    flash('Not allowed')
    return redirect(url_for('user.home'))
```

Advice: Know your code. They go deep into the code and ask for explanations and reasoning.

SimplePOST naya janam (har baar naya id). PUT poori photo replace. PATCH sticker chipkao.

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.

Advice: be through with you project especially the variables used and how they are passed etc the examiner is chill(even though he asks a lot of questions)

Official solution

SimpleGitHub repo open karo: commits, collaborators, README. Examiner check karta hai tumne khud kaam kiya.
Example
```
Settings → Collaborators
Commits: regular messages, last-day dump nahi.
```
Viva tipPrivate repo access pehle de do. Main branch submitted ZIP se match honi chahiye.

Then asked to give a demo of all the functionalities.

Times asked 2

Official solution

SimpleDemo script pehle se practice: 5–7 min, Admin + User roles, saare mandatory features.
Suggested flow1) Register/login user
2) Admin login — CRUD
3) Approval/blacklist
4) Booking/apply + edge case
5) Search
6) Logout

Authentication and authorisation based

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)
```

(Session or token) Then asked what is token based

Times asked 2
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().

Where did you implement caching and redis ? What is caching?

Times asked 1
Official solution

SimpleCache = pehli baar hisaab karke copy rakh lo, doosri baar copy dikha do.
Baar-baar same expensive kaam (DB query, counting bookings) mat karo. Result Redis jaise store mein timeout ke saath rakh do.
Cache hit: key mil gayi, DB skip. Cache miss: DB se lao, SET karo, return karo.
Tradeoff: speed vs stale data. Admin naya venue add kare aur cache 50s ka ho to user purani list dekh sakta hai — isliye write pe invalidation zaroori hai.
Browser cache, Flask-Caching, Redis alag layers hain. MAD2 examiner Redis + @cache.cached code dekhta hai.
Example
```
@cache.cached(timeout=50, query_string=True)
@app.route('/api/shows')
def shows():
    return jsonify([s.serialize() for s in Show.query.all()])
```
Project example: Admin dashboard counts / venues list cache. Create/update/delete ke baad cache.delete('venues').
Viva tipprint('DB queried') function ke andar laga ke miss/hit demo karo — hit pe print nahi chalega.

In the Frontend code, he asked me async ?, await?, what is Const? Why not we use let ?then mounted()( since it is there in my Frontend code so he asked this question)

Times asked 1
Official solution

SimpleonMounted = Composition API ka mounted. setup() ke andar call.
Options API: mounted() method. Mix mat. Vue 3 dono chalte.
Lifecycle = component ki zindagi: created (instance, DOM nahi) → mounted/onMounted (DOM ready — fetch, Chart.js yahi) → updated → unmounted (clearInterval).
Dashboard API created mein isliye nahi ki $el/canvas missing ho sakta. Composition API: onMounted(() => {}) setup ke andar. Options: mounted() method. Mix mat.
Examiner 'konsa hook use kiya' — related .vue kholo, line padh ke bolo.
Example
```
import { onMounted, ref } from 'vue'
const items = ref([])
onMounted(async () => {
  items.value = await (await fetch('/api/items')).json()
})
```
Project example: script setup: onMounted(loadStats).

Advice: He is very chill and nice but be thorough with your code line by line be it frontend or backend.
