PhytoVigil

🌿 PhytoVigil Backend

Backend for the PhytoVigil application, developed with FastAPI, featuring:

• 🔐 Secure JWT authentication
• 👤 User management with roles (user, admin)
• 🧠 AI module for plant disease detection (TensorFlow)
• 🗃️ PostgreSQL database (via SQLAlchemy)
• 📦 RESTful API with auto-generated Swagger documentation
• 🔄 Local storage and synchronization support
• 🤖 Integration with an AI API (e.g., Gemini API) to provide additional information and solutions for detected diseases

⚙️ Technologies Used

• FastAPI
• SQLAlchemy
• TensorFlow
• Pydantic
• PostgreSQL
• Python-JOSE
• Uvicorn

🚀 Running the Project Locally

1. Clone the project

git clone https://github.com/badie16/PhytoVigil.git
cd PhytoVigil/backend

2. Create and activate a virtual environment

python -m venv venv
source venv/Scripts/activate        # Windows (Git Bash)
# or
source venv/bin/activate            # Linux/macOS

3. Install dependencies

pip install -r requirements.txt

4. Configure the database

Create a .env file in the /backend/ directory:

DATABASE_URL=postgresql://username:password@localhost:5432/phytovigil
ALGORITHM=HS256
ACCESS_TOKEN_EXPIRE_MINUTES=60
GEMINI_API_KEY=your_gemini_api_key_here

5. Launch the API

uvicorn app.main:app --reload

Access auto-generated documentation:

• Swagger UI : http://127.0.0.1:8000/docs
• Redoc : http://127.0.0.1:8000/redoc

🧠 AI Module

The AI model is located in:

/app/ml/
├── model.h5         ← Trained TensorFlow model
├── class.json       ← ID to disease name mapping
└── diagnosis.py     ← Prediction code

🤖 Gemini Integration

The backend queries the Gemini API to provide users with detailed information and natural solutions for detected diseases, enhancing user experience with dynamic, tailored content.
