Summary of Changes

Hello @yadavchiragg, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the BHV project by introducing robust deployment capabilities, a comprehensive administrative interface, and a structured testing framework. While the title emphasizes documentation, the changes encompass substantial new code for Dockerization, an admin dashboard for user and image management, and a complete suite of unit and integration tests. The goal is to make the application easier to deploy, manage, and maintain, providing a more complete and production-ready solution.

Highlights

• Comprehensive Deployment Guide: A new detailed troubleshooting guide has been added to docs/DEPLOYMENT_TROUBLESHOOTING.md, covering common issues related to PostgreSQL, environment variables, static files, database migrations, port binding, memory optimization, and SSL/HTTPS configuration for production environments like Render.com.
• Docker Integration: The project now includes full Docker support with a Dockerfile, docker-compose.yml, and a dedicated DOCKER.md guide for quick setup, development, and production deployment using Docker and Docker Compose.
• Admin Dashboard and Management: A new administrative interface has been implemented, providing an overview dashboard with analytics, and dedicated pages for managing users and images, including functionalities like user deletion, image deletion, and toggling admin status.
• Enhanced Application Structure and Features: The core Flask application (bhv/app.py) has been significantly expanded to include new user authentication flows, image upload and gallery features, user profiles, and data export capabilities (CSV/JSON). New templates have been added for all these features, along with dedicated error pages.
• Improved Configuration and Build Process: A new config.py module centralizes application settings, init_db.py simplifies database initialization and admin user creation, and a build.sh script streamlines the build process for deployment platforms like Render.com, which also has its own render.yaml configuration.
• New Test Suite: A comprehensive test suite using Pytest has been introduced, covering authentication, image uploads, admin functionalities, user models, and security aspects, ensuring the stability and correctness of the new features.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request introduces a significant amount of new functionality, including a comprehensive admin dashboard, Docker support, and extensive documentation for deployment and troubleshooting. This is a fantastic addition to the project. However, the implementation has several critical issues that need to be addressed before merging. There are major security concerns with hardcoded credentials, conflicting and duplicated code (especially around admin routes and configuration), and inconsistencies between the code, tests, and documentation. My review focuses on resolving these critical and high-severity issues to ensure the application is secure, maintainable, and functions as described in the new documentation.
