SimpleRoute URL ko Python function se map karta hai. Decorator @app.route ya blueprint.route.

Example

@app.route('/lots', methods=['GET', 'POST'])
def lots():
    if request.method == 'POST':
        ...
    return render_template('lots.html', lots=Lot.query.all())

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.

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

class Lot(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    name = db.Column(db.String(80), nullable=False)
    spots = db.relationship('Spot', backref='lot', lazy=True)

SimpleCode explain formula: input kya aaya → auth/validation → DB change → response/UI.

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

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

SimpleJinja2 Flask ka template engine — HTML ke andar {{ }} variables, {% %} logic.

{% endfor %}

SimpleSQLAlchemy MAD1 ka common ORM. Flask-SQLAlchemy wrapper se db.Model, db.session.

db.session.add(user)
db.session.commit()
users = User.query.filter_by(role='admin').all()

SimpleGET data mangta hai (read), POST data bhejta hai (create/submit).

GETURL mein dikhta hai, bookmark ho sakta hai, browser back/refresh safe hai, data URL query mein jaata hai. Search, page open, login form dikhana.

POSTbody mein data jaata hai, URL mein password nahi dikhta, refresh pe dubara submit ho sakta hai. Login, register, form save.

Example

# page dikhana

@app.route('/login', methods=['GET', 'POST'])
def login():
    if request.method == 'GET':
        return render_template('login.html')
    # POST: form submit
    email = request.form.get('email')
    ...

GET se theoretically data bhej sakte ho (?q=flask), lekin create/update ke liye nahi use karna — data log/history mein save ho jaata hai, length limit hoti hai.
HTML form default GET hota hai; method='POST' likhna zaroori hai login/register pe.

SimpleBase template pe navbar/footer, child pages {% extends %} + {% block %} se content bharte hain. DRY.

Example

{# base.html #}
{% block content %}{% endblock %}

{# home.html #}
{% extends 'base.html' %}
{% block content %}
  <h1>Home</h1>
{% endblock %}

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)

SimpleGET data read/show karta hai (idempotent). POST create/submit karta hai (form).

Example

@app.route('/login', methods=['GET', 'POST'])
def login():
    if request.method == 'POST':
        # validate + session
        ...
    return render_template('login.html')

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'
