## Architecture ## Architecture
The Admin Panel is built using Python with the Flask web framework, using the following technologies: The Admin Panel is built using Go with the Gin web framework, using the following technologies:
* **Backend:** Python 3.11+, Flask * **Backend:** Go 1.23+, Gin Web Framework
* **Database:** PostgreSQL * **Database:** PostgreSQL with `lib/pq` driver
* **Template Engine:** Jinja2 * **Authentication:** Bcrypt for password hashing, Gorilla Sessions for session management
* **Authentication:** Werkzeug Security * **Email:** SMTP via `go-mail` library
* **Email:** SMTP (using `smtplib`) * **Containerization:** Podman/Docker with multi-stage builds
* **Containerization:** Docker * **Configuration:** Environment variables via `godotenv`
* **Configuration:** .env file using `python-dotenv`
## Setup & Deployment ## Setup & Deployment
### Prerequisites ### Prerequisites
* Docker (recommended for containerized deployment) * Podman or Docker (recommended for containerized deployment)
* Python 3.11+ (if running locally without Docker) * Go 1.23+ (if running locally without containers)
* A PostgreSQL database instance * A PostgreSQL database instance
* An SMTP account (e.g., SendGrid, Mailgun) for sending emails * An SMTP account (e.g., SendGrid, Gmail, Mailgun) for sending emails
* A `.env` file with configuration details * A `.env` file with configuration details
### .env Configuration ### .env Configuration
Create a `.env` file in the project root directory with the following environment variables. Make sure to replace the placeholder values with your actual credentials. Create a `.env` file in the project root directory with the following environment variables. Make sure to replace the placeholder values with your actual credentials.
```env ```env

### Running with Docker (Recommended) ### Running with Podman (Recommended)
This is the recommended approach for deploying the RideAware Admin Panel This is the recommended approach for deploying the RideAware Admin Panel.
Building the Docker image: **Building the image:**
```sh ```sh
docker build -t admin-panel . podman build -t admin-panel:latest .
``` ```
Running the container mapping port 5001: **Running the container:**
```sh ```sh
docker run -p 5001:5001 admin-panel podman run -d \
--name admin-panel \
-p 5001:5001 \
--env-file .env \
admin-panel:latest
```
**Viewing logs:**
```sh
podman logs -f admin-panel
``` ```
The application will be accessible at `http://localhost:5001` or `http://<your_server_ip>:5001` The application will be accessible at `http://localhost:5001` or `http://<your_server_ip>:5001`
*Note: When running locally with Docker, ensure the .env file is located at the project root. Alternatively, you can pass the variables in the CLI.* ### Running with Podman Compose
### Running locally Create a `podman-compose.yml`:
Install Dependencies: ```yaml
version: '3.8'
```sh services:
pip install -r requirements.txt admin-panel:
build: .
ports:
- "5001:5001"
env_file:
- .env
depends_on:
- postgres
restart: unless-stopped
postgres:
image: docker.io/library/postgres:15-alpine
environment:
POSTGRES_USER: ${PG_USER}
POSTGRES_PASSWORD: ${PG_PASSWORD}
POSTGRES_DB: ${PG_DATABASE}
ports:
- "5432:5432"
volumes:
- postgres_data:/var/lib/postgresql/data
restart: unless-stopped
volumes:
postgres_data:
``` ```
Set Environment Variables: Then run:
Ensure all the environment variables specified in the `.env` configuration section are set in your shell environment. You can source the `.env` file:
Then run the admin app:
```sh ```sh
python app.py podman-compose up -d
podman-compose logs -f admin-panel
```
### Running Locally (Development)
**Install Go 1.23+**
Ensure you have Go installed. Download from [golang.org](https://golang.org/dl)
**Install dependencies:**
```sh
go mod tidy
```
**Run the application:**
```sh
go run ./cmd/admin-panel
``` ```
The app will be accessible at `http://127.0.0.1:5001` The app will be accessible at `http://127.0.0.1:5001`
### Contributing **For hot-reloading during development, install `air`:**
```sh
go install github.com/cosmtrek/air@latest
air
```
## API Endpoints
| Method | Endpoint | Description | Protected |
|--------|----------|-------------|-----------|
| GET | `/login` | Login page | No |
| POST | `/login` | Submit login credentials | No |
| GET | `/logout` | Logout and clear session | Yes |
| GET | `/` | View subscriber list | Yes |
| GET | `/send_update` | Newsletter compose form | Yes |
| POST | `/send_update` | Send newsletter to all subscribers | Yes |
## Development
### Adding New Features
1. Create a new handler in `internal/handlers/`
2. Add routes in `cmd/admin-panel/main.go`
3. Add any new dependencies to `go.mod` via `go get`
4. Run `go mod tidy` to sync dependencies
### Database Migrations
The application automatically creates required tables on startup if they don't exist. To add new tables, modify the `createTables()` function in `internal/database/database.go`.
### Environment Variables
Configuration is centralized in `internal/config/config.go`. All environment variables are loaded via the `godotenv` package. Defaults are provided for development.
## Contributing
Contributions to the RideAware Admin Panel are welcome! Please follow these steps: Contributions to the RideAware Admin Panel are welcome! Please follow these steps:
* Fork the repository. * Fork the repository.
* Create a new branch for your feature or bug fix. * Create a new branch for your feature or bug fix.
* Make your changes and commit them with descriptive commit messages. * Make your changes and commit them with descriptive commit messages.
* Ensure code builds with `go build ./cmd/admin-panel`
* Run `go fmt ./...` to format code
* Submit a pull request. * Submit a pull request.
## Troubleshooting
**Database Connection Failed**
* Verify PostgreSQL is running and accessible
* Check `PG_HOST`, `PG_PORT`, `PG_USER`, and `PG_PASSWORD` in `.env`
* Test connection manually: `psql -h <host> -U <user> -d <database>`
**Email Not Sending**
* Verify SMTP credentials are correct
* Check `SMTP_SERVER` and `SMTP_PORT` match your email provider
* For Gmail, use an [app-specific password](https://support.google.com/accounts/answer/185833)
* Check container logs for SMTP errors
**Session/Login Issues**
* Ensure `SECRET_KEY` is set and consistent
* Clear browser cookies and try again
* Check that `GIN_MODE` is not set to `release` in development
