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

SimpleTheory = concepts: ORM, MVC, auth vs authz, Jinja inheritance, sessions. 1-line def + project example.

SimpleLive Flask coding: chhota route likho, save, browser/curl se test. Syntax error terminal mein padho.

Example

@app.route('/ping')
def ping():
    return jsonify(ok=True)

@app.route('/even/<int:n>')
def even(n):
    return 'even' if n % 2 == 0 else 'odd'

SimpleIndex = column pe shortcut book — WHERE/JOIN tez. PK auto-indexed. Email/unique filters pe index socho.

Example

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

SimpleNormalisation: redundant data kam, tables todna. 1NF atomic, 2NF partial dep hatao, 3NF transitive dep hatao.

Viva tip

Exampleuser address alag table vs har booking mein dubara store.

SimpleDijkstra shortest path in weighted graph (non-negative). Priority queue + distances. Parking app se related nahi usually — algo side Q.

SimpleTime complexity input size ke saath time kaise badhta hai.

O(1): dict lookup. O(n): list mein loop. O(n^2): nested loops.

Example

User.query.all() phir Python mein filter = O(n). DB pe indexed WHERE tez.

Search suggestions: prefix index / ILIKE, nai to har keypress pe poori table mat ghumao.

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 }"

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'

Viva tipFlask micro hai: jo chahiye (DB, login, forms) khud jodte ho.

SimpleCSRF: attacker tumhari logged-in browser se unwanted POST. CSRF token form mein proof hai request genuine hai.

Viva tipFlask-WTF CSRF protect karta hai. Token bina POST reject.
