- | ====== Development Plan ====== | ||
- | |||
- | ===== ENGLISH VERSION ===== | ||
- | |||
- | |||
- | AIM: To make a QR-code generator to generate qr codes from a wiki: https:// | ||
- | |||
- | **Schema and implement security features** | ||
- | |||
- | Schema and implement security features to ensure the confidentiality of contact information: | ||
- | |||
- | 1. Tables: | ||
- | Contacts Table | ||
- | Fields: | ||
- | * ContactID (Primary Key) | ||
- | * Name | ||
- | |||
- | * Phone | ||
- | * Expertise (e.g., electronics, | ||
- | |||
- | Tools Table | ||
- | Fields: | ||
- | * ToolID (Primary Key) | ||
- | * Name | ||
- | * Description | ||
- | * Category | ||
- | * Quantity | ||
- | * Location | ||
- | * Condition (e.g., new, used) | ||
- | * Availability (e.g., available, checked out) | ||
- | |||
- | QR Codes Table: | ||
- | Fields: | ||
- | * QRCodeID (Primary Key) | ||
- | * ToolID (Foreign Key referencing Tools) | ||
- | * Link | ||
- | * CreationTimestamp | ||
- | |||
- | 2. Website Contact Form | ||
- | * Implement a contact form on your website where users can submit inquiries or requests to contact specific individuals. | ||
- | * When a user submits the form, the website backend will handle the request and forward it to the appropriate contact without revealing their email address or phone number. | ||
- | 3. Security Measures | ||
- | * Encryption: Encrypt sensitive data (such as email addresses and phone numbers) in the database to prevent unauthorized access. | ||
- | * Access Control: Implement access controls to restrict access to contact information only to authorized users with appropriate permissions. | ||
- | * Authentication: | ||
- | * Secure Communication: | ||
- | |||
- | By implementing these security measures, you can protect the privacy of contact information while still facilitating communication between users and contacts through the website. Users can submit inquiries or requests without directly accessing contact details, maintaining confidentiality and security. | ||

- | |||
- | **Tech Stack** | ||
- | |||
- | Development stack tailored to using PostgreSQL and Hacklab' | ||
- | |||
- | 1. Frontend Framework: Flutter | ||
- | Flutter will be used for building the mobile and web frontend of your application. Flutter' | ||
- | 2. Backend Framework: Django | ||
- | Django will serve as the backend framework for your application, | ||
- | 3. Database: PostgreSQL | ||
- | PostgreSQL remains the chosen database management system for storing structured data such as tools, contacts, and QR code information. Django has excellent support for PostgreSQL through its ORM, allowing seamless integration with the backend. | ||
- | 4. Authentication and Security: Django Authentication | ||
- | Django provides built-in authentication and authorization features, including user authentication, | ||
- | 5. Integration with Brother P-touch Cube Printer: Brother Mobile SDK | ||
- | Integrate the Brother Mobile SDK with your Flutter application for printing QR codes using the Brother P-touch Cube printer, as previously discussed. The integration will be handled primarily on the frontend side, with Flutter communicating with the printer SDK. | ||
- | 6. Deployment: Deployment to Cloud Platform | ||
- | Deploy your Django backend and Flutter frontend to a cloud platform such as AWS (Amazon Web Services), Google Cloud Platform, or Heroku. These platforms offer scalable infrastructure, | ||
- | |||
- | By using this development stack, you can leverage PostgreSQL' | ||
- | |||
- | By adopting Django as the backend framework alongside Flutter for frontend development, | ||
- | |||
- | **Mobile First** | ||
- | |||
- | Given that your web application will primarily be accessed by users at the Hacklab and you want to prioritize mobile accessibility, | ||
- | |||
- | Here are some considerations for implementing a mobile-first approach: | ||
- | |||
- | 1. Responsive Design: Design your user interface to adapt seamlessly to various screen sizes, from smartphones to tablets and desktops. Utilize CSS media queries and flexible layout techniques to ensure that content is displayed appropriately across different devices. | ||
- | 2. Touch-Friendly Interactions: | ||
- | 3. Performance Optimisation: | ||
- | 4. Progressive Web App (PWA) Features: Consider implementing PWA features such as offline caching, push notifications, | ||
- | 5. Cross-Platform Compatibility: | ||
- | |||
- | Regarding printing QR codes, your approach of having a printer connected to a computer (or network) for automatic printing or manually sending image files to the printer can work well. You may need to integrate your web application with a printing solution or service to facilitate the generation and printing of QR codes directly from the application. | ||
- | |||
- | By adopting a mobile-first approach and considering the printing requirements, | ||
- | |||
- | |||
- | |||
- | **Printing QR Code Labels** | ||
- | |||
- | With the Android Labeling and Mobile SDK provided by Brother, you can integrate the Brother P-touch Cube label printer with your Android mobile application for printing QR codes. | ||
- | |||
- | https:// | ||
- | |||
- | Here's how you can proceed with the integration: | ||
- | |||
- | 1. Download and Install the SDK: | ||
- | - Download the Android Labeling and Mobile SDK from the provided link. | ||
- | - Follow the installation instructions and setup process outlined in the SDK documentation. | ||
- | 2. Explore SDK Documentation: | ||
- | - Familiarize yourself with the documentation provided with the SDK. It should include information on APIs, usage examples, and best practices for integrating with Brother label printers. | ||
- | 3. Integrate SDK with Your Android Application: | ||
- | - Add the Brother Mobile SDK to your Android project by including the necessary dependencies and configurations. | ||
- | - Set up your Android application to communicate with the Brother P-touch Cube printer using the SDK. | ||
- | - Utilize the SDK's APIs to send print commands and data to the printer from your Android application. | ||
- | 4. Generate QR Codes Dynamically: | ||
- | - Implement logic within your Android application to generate QR codes dynamically based on user input or database queries. | ||
- | - Use a QR code generation library compatible with Android, such as ZXing (Zebra Crossing), to generate QR code images programmatically. | ||
- | 5. Handle User Interaction: | ||
- | - Create a user interface in your Android application for triggering QR code printing. | ||
- | - When a user initiates a print action, invoke the necessary SDK methods to generate the QR code image and initiate printing on the Brother P-touch Cube printer. | ||
- | 6. Printer Configuration: | ||
- | - Ensure that the Brother P-touch Cube printer is connected to the Android device via Bluetooth or another compatible connection method. | ||
- | - Configure the printer settings, such as label size, orientation, | ||
- | 7. Testing and Debugging: | ||
- | - Test the integration thoroughly to ensure that QR codes are generated accurately and printed correctly by the Brother P-touch Cube printer. | ||
- | - Debug any issues that arise during integration, | ||
- | 8. Documentation and Support: | ||
- | - Refer to the SDK documentation and resources provided by Brother for troubleshooting, | ||
- | - Reach out to Brother' | ||
- | |||
- | By following these steps and leveraging the capabilities of the Android Labeling and Mobile SDK provided by Brother, you can seamlessly integrate the Brother P-touch Cube label printer with your Android mobile application to enable users to generate and print QR codes for labeling tools and equipment at the Hacklab. | ||
