SimpleExaminer portal wala submitted ZIP chahta hai. Local extra changes mat dikhana.

Suggested flow1) Portal ZIP download
2) Extract
3) venv + pip install -r requirements.txt
4) flask run / python app.py

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'

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

SimpleExaminer submitted ZIP chahta hai, local extra changes nahi.

Portal se ZIP download → extract → venv → pip install -r requirements.txt → flask run / python app.py.
Checksum maange to hash match karke dikhao. Camera/OPPE setup unke instructions.
Linux/Mac: paths, gunicorn; Windows paths alag ho to relative paths use karo.
Do browsers: admin + user parallel demo impressive lagta hai.

SimpleGitHub repo public/private policy ke hisaab, MAD-1 collaborator add, commits dikhao.

Repo → Settings → Collaborators → instructor added.
Commits: git log / GitHub History — regular commits better, ek dum 1 commit suspicious.
README + report mein AI usage likha hona chahiye agar use kiya.

Patternfilter query → template/JSON. Examiner jo entity bole us class ka naam use karo.

@app.route('/admin/blacklisted')
def blacklisted():
    rows = User.query.filter_by(is_blacklisted=True).all()
    return render_template('list.html', rows=rows)

JSON: return jsonify([{'id': r.id, 'name': r.name} for r in rows])
ID se: User.query.get_or_404(id)
Do filters: .filter(Drive.approved==False, Drive.title=='Data Scientist')

Join example: students jinhone blacklisted company ke drive pe apply kiya — join Application-Drive-Company.

PUT@app.route('/x/<int:id>', methods=['PUT']) + request.get_json()

url param display: @app.route('/show/<int:id>') return render_template('show.html', id=id)
Form → next page: POST values render_template('out.html', **request.form)
Count: return str(User.query.filter_by(is_blacklisted=True).count())

SimpleForm user input server ko bhejti hai. Table rows/columns dikhati hai.

<form action="{{ url_for('register') }}" method='POST' enctype='multipart/form-data'>
  <input name='email' required>
  <button type='submit'>Go</button>
</form>

name attribute server pe key ban'ti hai: request.form['email']. id JS/CSS, value default/dikhta hua text.
action URL. method GET/POST. enctype file upload pe multipart.
required frontend empty submit rokta hai (backend phir bhi check).

<table><thead><tr><th>Name</th></tr></thead><tbody><tr><td>{{ u.name }}</td></tr></tbody></table>

th header, td data, tr row. Nested table: td ke andar table (avoid, messy).
method hataoge to GET, password URL mein — buri baat.

SimpleStatus code number batata hai request ka result.

200 OK — success, page/data mil gaya.
201 Created — POST se naya resource.
302/303 Found/See Other — redirect (login ke baad).
304 Not Modified — cache use karo.
400 Bad Request — galat input.
401 Unauthorized — login nahi (ironically authentication missing).
403 Forbidden — login hai, permission nahi.
404 Not Found — route/record nahi.
500 Internal Server Error — server crash (DB error, NoneType). debug=True pe traceback.
501 Not Implemented — method server nahi sambhalta.

abort(404) Flask mein. get_or_404(id) record na ho to 404.
User ID GET pe exist na kare to 404 return karo, 500 nahi.
