Logist Medicine Delivery: User Registration and Login System

How can the Logist Medicine Delivery app benefit different user roles?

The Logist Medicine Delivery app caters to three distinct user roles: patients, doctors, and pharmacies. Patients can manage their medicine deliveries and prescriptions, making it easier to receive necessary medications. Doctors can efficiently manage their patients and prescriptions, streamlining the process of issuing and tracking medication orders. Pharmacies can manage their medicine inventory and deliveries, optimizing their supply chain and ensuring timely delivery of medications to patients. This multi-role approach in Logist Medicine Delivery creates a comprehensive ecosystem for medication management and delivery.

What security measures are in place to protect user data in the Logist Medicine Delivery app?

The Logist Medicine Delivery app implements several security measures to protect user data: - Passwords are hashed using the Werkzeug security module before storage, ensuring that plain text passwords are never stored in the database. - User sessions are managed securely using Flask's session management. - The app uses HTTPS (assumed, as it's a best practice) to encrypt data in transit. - Input validation is performed on the server-side to prevent malicious data entry. - The app uses prepared statements (via SQLAlchemy) to prevent SQL injection attacks.

How can the Logist Medicine Delivery app be expanded to include additional features for each user role?

The Logist Medicine Delivery app can be expanded in several ways: - For patients: Add features like medication reminders, refill requests, and telemedicine consultations. - For doctors: Implement electronic prescription writing, patient history viewing, and appointment scheduling. - For pharmacies: Include inventory management tools, automated reordering systems, and delivery tracking. These expansions would make Logist Medicine Delivery a more comprehensive solution for medication management and healthcare delivery.

How does the Logist Medicine Delivery app handle user authentication and role-based access control?

The Logist Medicine Delivery app handles user authentication and role-based access control through its login system and session management. Here's a code snippet from the routes.py file that demonstrates this:

```python @app.route("/login", methods=["GET", "POST"]) def login(): if request.method == "POST": email = request.form.get("email") password = request.form.get("password") user = get_user_by_email(email)

       if user and check_password_hash(user['password'], password):
           session["user_id"] = user['id']
           session["user_email"] = user['email']
           session["user_role"] = user['role']
           return redirect(url_for("dashboard"))
       else:
           flash("Incorrect email or password. Please try again.", "danger")
   return render_template("login.html")

@app.route("/dashboard") def dashboard(): if "user_id" not in session: return redirect(url_for("login"))

   user_role = session.get("user_role")
   if user_role in ["patient", "doctor", "pharmacy"]:
       return render_template(f"{user_role}_dashboard.html")
   else:
       flash("Invalid user role.", "danger")
       return redirect(url_for("home_route"))

```

This code authenticates users, stores their role in the session, and directs them to the appropriate dashboard based on their role.

How does the Logist Medicine Delivery app handle database migrations?

The Logist Medicine Delivery app uses a custom migration system to manage database schema changes. Here's a snippet from the run_migrations.py file that demonstrates how migrations are handled:

```python def run_migrations(app): migration_folder = os.path.join(app.root_path, 'migrations') if not os.path.exists(migration_folder): logging.info("No migrations folder found. Skipping migrations.") return

   with app.app_context():
       db.create_all()

       migration_files = sorted(f for f in os.listdir(migration_folder) if f.endswith('.sql'))

       for migration_file in migration_files:
           migration_record = Migration.query.filter_by(name=migration_file).first()

           if migration_record is None:
               with open(os.path.join(migration_folder, migration_file), 'r') as file:
                   migration_sql = file.read()

               logging.info(f"Running migration: {migration_file}")
               db.session.execute(text(migration_sql))

               new_migration = Migration(name=migration_file)
               db.session.add(new_migration)
               db.session.commit()
               logging.info(f"Migration {migration_file} completed successfully.")
           else:
               logging.info(f"Migration {migration_file} already applied. Skipping.")

```

This system reads SQL files from a migrations folder, executes them in order, and keeps track of applied migrations to ensure they're only run once. This allows the Logist Medicine Delivery app to evolve its database schema over time without manual intervention.
