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 %}

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.

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'

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.

SimpleCSS 3 tarikon se lagti hai, priority Inline > Internal > External (same specificity pe).

Inline: style='color:red' element pe. Highest priority, lekin reuse nahi. Debugging mushkil.
Internal: <style> tag HTML head mein. Us page tak limited.
External: style.css file. Large project ke liye best — ek jagah change, saari pages update.

Example same button pe teeno:
/* external */ .btn { color: blue; }
/* internal */ .btn { color: green; }
<!-- inline --> <button class='btn' style='color:red'> → red jeetega

ID (#box) class (.btn) se strong, class element (button) se strong.
!important sabko override karta hai — avoid karo.
Large project: external CSS preferred.

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().

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

SimpleInt column mein string daalne pe SQLAlchemy/DB type error ya Integrity/StatementError. Empty table pe bhi same validation fail — row count matter nahi.

Example

# SQLite may coerce sometimes; Postgres: invalid input syntax for integer
Spot(status='free', lot_id='abc')  # lot_id int → error

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)

SimpleValidation = input rules: required, email format, length, unique. Frontend UX, backend security — dono.

Example

if not email or '@' not in email:
    flash('Invalid email')
    return redirect(request.url)
if User.query.filter_by(email=email).first():
    flash('Email taken')

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