    Times asked 1

  4. 4
    Downloaded project
    Times asked 1
    Official solution

    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

  5. 5
    Login in admin
    Times asked 1
    Official solution

    SimpleLogin flow pehle poochta hai "tu kaun hai?", token milne ke baad har API pe wohi proof dikhate ho.

    Authentication step: Vue form email + password JSON POST karta hai. Flask user dhoondhta hai, check_password_hash se prove karta hai ki tum genuine ho. Galat 401. Sahi pe JWT + role milta hai — yeh session/token hai.

    Vue localStorage (ya cookie) mein token rakhta hai, dashboard pe router.push. Aage ki har fetch header: Authorization: Bearer <token>. @jwt_required identity check (authentication). @roles_required('admin') permission check (authorization) — logged in ho, lekin allowed nahi to 403.

    Validation alag cheez hai: empty email, password 8+ — form sahi bhara hai ya nahi. Woh identity prove nahi karta.

    Logout = client token delete + login page. Server blacklist optional. Password response JSON mein kabhi mat bhejo.

    Example

    # Authentication
    @app.route('/api/login', methods=['POST'])
    def login():
        u = User.query.filter_by(email=data['email']).first()
        if not u or not check_password_hash(u.password, data['password']):
            return jsonify(msg='bad'), 401
        return jsonify(token=create_access_token(u.id), role=u.role)
    
    # baad ki APIs
    # Authorization: Bearer <token>
    if current_user.role != 'admin':
        abort(403)

    Project example: Login.vue POST /api/login → token LS → interceptor. Student token se admin route = 403. Empty form = validation, galat password = 401.

    Viva tipNetwork tab mein password body dikhega localhost pe — prod HTTPS. Response mein hash/password echo mat karo.

Advice: Make sure to thoroughly go through the models.py and app.py. Once hes convinced you thoroughly understand each and every word of these two files, he wont test you further by asking more theory questions. The proctor should just be convinced you have understood the backend ie the controller part and then he lets you leave early.
