Model.py explanation and what are relationships in the model.py

Times asked 2
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')
```

Advice: Prepare for the theory questions, know your project's code very well and do practice a bit for the coding question even though it is very easy. He is chill but was a bit late for the viva and seemed quite distracted like after answering a question there was a considerable amount of silence after which he said 'ok' and asked the next question. He said to me that I need to have better understanding of backend like APIs and that it would have been better that I had implemented that missing functionality and some additional functionalities like graphs for the placement report.

My function was of deleting the doctor, but i named that as 'Blacklist'(in ui). Said Change the name from 'Blacklist' to 'Delete'. I searched & updated.

Times asked 2
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()
```
4
Where you have used cache? Told me add a print statement in the route & asked how much will it be printed in that particular timeout time duration?

Times asked 2
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.
5
What are lifecycle hooks? Where you have used & why?

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.

In appointment table, why did you use separate date and time columns instead of a single datetime?

Times asked 1

Official solution

SimpleAlag date/time: filter aaj ke shows, forms alag. Single DateTime sorting easy. Honest.
Why separate date and time columns.
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: If one datetime, say that.
8
Login as doctor → go to Developer Tools → Applications → LocalStorage → change role to admin and update URL → why are you able to access admin screen?

Times asked 2
Official solution

SimplelocalStorage browser mein key-value string store karta hai — tab band hone pe bhi rehta hai. Token/theme ke liye use.
Example
```
localStorage.setItem('token', jwt)
const t = localStorage.getItem('token')
localStorage.removeItem('token')
```
Viva tipSensitive password mat rakho. XSS se steal ho sakta hai — HttpOnly cookie safer for session.

Where are all frontend URLs stored?

Times asked 2

Official solution

SimpleUngli rakhe to 4-line formula — panic ki jagah structure.
1) File ka role: model / Flask route / Vue SFC / celery task / config
2) Input kahan: JSON, params, token, props, $route
3) Kya kaam: query, cache, validation, .delay()
4) Output: jsonify, this.items, email, redirect
Unknown keyword: import, decorator, if, commit — har ka reason. Bluff mat.
Suggested flow1) Kaunsi layer?
2) Input?
3) DB/cache/task?
4) Response/UI?
Project example: Booking POST: jwt, seats check, commit, 201, Vue list push.
Viva tipUnknown keyword: import, decorator, if, commit — har ka reason. Panic mat.
10

Where is caching implemented in your project?

Times asked 2

Official solution

SimpleHaan Redis routes X demo hit miss. Nahi: kaise add karte — decorator + redis + invalidation.
Don't lie. Examiner code dekhega.
Redis in-memory key-value store hai — fridge pe sticky note, poori kitchen (SQL database) har baar mat kholo.
MAD2 mein Redis do kaam: (1) cache — same venues/shows/dashboard JSON baar-baar DB se nahi (2) Celery broker — Flask task queue mein daalta hai, worker uthata hai.
Flow: cache.get(key) → hit pe return, miss pe SQLAlchemy + SET with timeout. Admin write ke baad cache.delete, warna stale list.
Source of truth database hi hai. Redis crash/band = cache miss (app chalni chahiye) + queue ruk sakti hai. Important bookings sirf Redis mein mat rakho.
Alag: Redis ≠ Memcached (Celery broker nahi). Redis ≠ localStorage (woh browser). redis-cli ping → PONG viva proof.
Project example: If yes open decorator. If no 4-step plan.
11
When cache.clear() deletes all data, how will you clear cache for only one specific route (e.g., doctor edit)?

Times asked 2
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.

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.
12
What are the benefits of Vue.js (including from user perspective)?

Times asked 2
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.
13
Difference between v-if and v-show in depth

Times asked 2
Official solution

Simplev-if ghar se nikaal deta hai (DOM se). v-show sirf light band karta hai (display:none).
v-if false → element exist hi nahi — costly create/destroy, lekin secret HTML DOM mein nahi.
v-show → hamesha DOM, CSS hide, toggle tez.
Rare / permission UI: v-if (admin panel). Dropdown bar-bar: v-show.
: shorthand v-bind ka, v-if ka nahi.
Example
```
<div v-if="isAdmin">Admin panel</div>
<div v-show="open">Dropdown</div>
```
Project example: Admin links v-if="role==='admin'". FAQ accordion v-show="open".
Viva tipSecurity ke liye sirf v-if kaafi nahi — API 403 bhi chahiye.

In Vue.js, how do you pass data between different components (props, emit)?

Times asked 1

Official solution

SimpleProps parent→child values. Emit child→parent signal. Basic communication.
Difference props and emit.
Component = reusable UI block (Navbar, Card). Props parent→child data, emit child→parent event. Slots parent HTML inner content.
computed cache + reactive derive (filtered list). watch side-effect (query change pe API). methods events. ref() primitive, reactive() object. Vuex/Pinia global store; localStorage persist, store nahi.
SFC: template + script + style ek .vue file. Parent-child exam favourite: list parent, row child :item + @delete.
Project example: Card props venue emit select.

18
What is emit? Is it a variable or something else?

Times asked 2
Official solution

Simpleemit = child parent ko chillata hai: 'delete 5'. Props down, events up.
this.$emit('delete', id). Parent @delete="removeRow".
Grandchild: chain emit ya Vuex/provide.
Component = reusable UI block (Navbar, Card). Props parent→child data, emit child→parent event. Slots parent HTML inner content.
computed cache + reactive derive (filtered list). watch side-effect (query change pe API). methods events. ref() primitive, reactive() object. Vuex/Pinia global store; localStorage persist, store nahi.
SFC: template + script + style ek .vue file. Parent-child exam favourite: list parent, row child :item + @delete.
Example
```

// parent: <Child @delete="removeRow" />
```
Project example: BookingRow emit cancel → parent list se hata + API DELETE.
19
Can Unique Key be used for making connections (relationships)?

Times asked 2
Official solution

Simpledb.relationship se object graph: lot.spots, booking.user. backref reverse side auto deta hai.
Example

Advice: He is chill but was a bit late for the viva and he also seemed a bit distracted to me like for example after I showing him some functionality of the app he asked again did you do that functionality but he is not very strict like I was unable to give good answers for the theory questions but was able to do the coding question so he did pass me for this level 1 viva. So, be confident, practice for the coding question and go through the theory questions.
