# 🏒 Paydirt NHL Model Updates
A Streamlit application for generating NHL DFS lineup projections and updating model data in real-time.
## Features
- **NHL Lineup Generation**: Automated lineup optimization for DraftKings and FanDuel
- **Real-time Updates**: Integrates with Google Sheets for live data updates
- **Multiple Platforms**: Supports both DK and FD contests
- **Ownership Projections**: ML-powered ownership predictions using XGBoost, LightGBM, and KNN models
- **Discord Notifications**: Automatic notifications when updates complete
- **MongoDB Integration**: Stores historical data and projections
## Architecture
- **Python/Streamlit**: Web interface and data processing
- **Go**: High-performance lineup generation
- **MongoDB**: Data storage and retrieval
- **Google Sheets API**: Live data integration
- **Docker**: Containerized deployment
## Setup
### Local Development
1. **Install Dependencies**
```bash
pip install -r requirements.txt
```
2. **Configure Secrets**
Create `.streamlit/secrets.toml`:
```toml
MONGODB_URI = "your-mongodb-uri"
GOOGLE_PROJECT_ID_1 = "your-project-id"
# ... (see .streamlit/secrets.toml.example for full template)
```
3. **Build Go Programs** (if developing locally on Windows)
```bash
cd func/dk_nhl_go
go build -o NHL_seed_frames.exe NHL_seed_frames.go
cd ../fd_nhl_go
go build -o NHL_seed_frames.exe NHL_seed_frames.go
```
4. **Run the App**
```bash
streamlit run src/streamlit_app.py
```
### Hugging Face Deployment
This app is configured for deployment on Hugging Face Spaces using Docker.
1. **Create a Space** on Hugging Face with Docker SDK
2. **Add Secrets** in Space settings (Settings → Repository secrets)
- Add all variables from `.streamlit/secrets.toml.example`
3. **Push Code** to your Space repository
4. The Docker build will automatically:
- Build Go programs for Linux
- Install Python dependencies
- Configure the environment

## Environment Variables
Required environment variables (can be set in `.streamlit/secrets.toml` or as environment variables):
| Variable | Description |
|----------|-------------|
| `MONGODB_URI` | MongoDB connection string |
| `GOOGLE_PROJECT_ID_1` | Google Cloud project ID (primary) |
| `GOOGLE_PRIVATE_KEY_1` | Service account private key (primary) |
| `GOOGLE_CLIENT_EMAIL_1` | Service account email (primary) |
| `GOOGLE_PROJECT_ID_2` | Google Cloud project ID (backup) |
| `GOOGLE_PRIVATE_KEY_2` | Service account private key (backup) |
| `GOOGLE_CLIENT_EMAIL_2` | Service account email (backup) |
| `DISCORD_WEBHOOK_URL` | Discord webhook for notifications |
| `MASTER_SHEET_URL` | Google Sheets URL for master data |
## Usage
1. Open the app in your browser
2. Check connection status in the sidebar
3. Click "🚀 Generate NHL Lineups" to start the process
4. Monitor progress as the app:
- Builds prop betting tables
- Generates player-level outcomes
- Creates stack matrices
- Runs lineup optimization
- Updates MongoDB with results
- Sends Discord notifications
## Security Notes
- Never commit `.streamlit/secrets.toml` to version control
- Use Hugging Face Secrets for production deployment
- Rotate service account keys regularly
- Keep MongoDB credentials secure
