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'

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.

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

Viva tipFunction signature + 3-4 important lines + edge case.

SimplePehle 1-line definition, phir apne MAD1 project mein file dikhao, phir chhota example.

Suggested flow1) Concept kya hai?
2) Mere code mein kahan?
3) Example / demo
4) Edge case

Example

# related file: models.py / routes / template
# formula: request → check/auth → DB → render/redirect

Viva tipExact line yaad nahi to honestly related part dikhao. Bluff mat karo.

SimpleViva wrap-up hai. Short thanks + confirm submission ZIP latest hai.

SimpleLive UI change: relevant CSS/HTML template kholo — color, margin, flex, bootstrap class. Save + hard refresh.

Example

/* button red */
.btn-primary { background: red; }

/* center navbar item */
.navbar { justify-content: center; }

Viva tipDevTools se pehle try, phir file mein permanent change.

SimpleORM = Object Relational Mapping. Tables → Python classes. Raw SQL kam likhte ho.

Example

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    email = db.Column(db.String(120), unique=True)

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

SimplePrimary key row ka unique identity — usually id Integer autoincrement.

Example

id = db.Column(db.Integer, primary_key=True)

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().

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)

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.

Simpleurl_for endpoint name se URL banata hai — hardcode path mat likho.

Example

url_for('auth.login')
url_for('static', filename='css/style.css')

Yeh MAD-1 viva question tumhare project ke context se linked hai. Short answer is structure se do:

Pehle 1 line definition/purpose, phir tumhare project ka example, phir chhota code/flow.

Typical Flask flowBrowser request → @app.route controller → SQLAlchemy model/DB → Jinja template response.

Auth: session['user_id'] + role check. CRUD: add/commit, query.all, field update, delete.
Live change maange to: related model → route → template, phir browser refresh karke dikhao.

Example (generic create):
obj = Model(name=request.form.get('name'))

db.session.add(obj); db.session.commit()
return redirect(url_for('list_view'))
