## Configuration

### Settings Modules

The project uses different settings modules for different environments:

- `config.settings.development` - Local development
- `config.settings.production` - Production deployment
- `config.settings.selfhosted` - Self-hosted instances

Set via environment variable:
```bash
export DJANGO_SETTINGS_MODULE=config.settings.development
```

### Database Configuration

The application supports multiple database backends. Choose the one that fits your needs.

#### SQLite3 (Default - Development)

SQLite3 is the default database and requires no additional setup. It's perfect for development and single-user scenarios.

**Configuration in `config/settings/development.py`:**
```python
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': BASE_DIR / 'db.sqlite3',
    }
}
```

**Pros:**
- Zero configuration
- No separate database server needed
- Perfect for development and testing

**Cons:**
- Not recommended for production with multiple users
- Limited concurrent write operations
- No network access (local file only)

#### PostgreSQL (Recommended for Production)

PostgreSQL is the recommended database for production deployments.

**1. Install PostgreSQL:**
```bash
# Ubuntu/Debian
sudo apt-get install postgresql postgresql-contrib libpq-dev

# macOS
brew install postgresql
```

**2. Create database and user:**
```bash
sudo -u postgres psql
CREATE DATABASE keepitgoing;
CREATE USER keepitgoing_user WITH PASSWORD 'your_secure_password';
ALTER ROLE keepitgoing_user SET client_encoding TO 'utf8';
ALTER ROLE keepitgoing_user SET default_transaction_isolation TO 'read committed';
ALTER ROLE keepitgoing_user SET timezone TO 'UTC';
GRANT ALL PRIVILEGES ON DATABASE keepitgoing TO keepitgoing_user;
\q
```

**3. Install Python driver:**
```bash
pip install psycopg2-binary
```

**4. Update settings:**

Add to your `.env` file:
```bash
DATABASE_URL=postgresql://keepitgoing_user:your_secure_password@localhost:5432/keepitgoing
```

Or configure directly in settings:
```python
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'keepitgoing',
        'USER': 'keepitgoing_user',
        'PASSWORD': 'your_secure_password',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}
```

**5. Run migrations:**
```bash
python manage.py migrate
```

#### MariaDB/MySQL

MariaDB and MySQL are also supported for production use.

**1. Install MariaDB:**
```bash
# Ubuntu/Debian
sudo apt-get install mariadb-server libmariadb-dev

# macOS
brew install mariadb
```

**2. Create database and user:**
```bash
sudo mysql
CREATE DATABASE keepitgoing CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
CREATE USER 'keepitgoing_user'@'localhost' IDENTIFIED BY 'your_secure_password';
GRANT ALL PRIVILEGES ON keepitgoing.* TO 'keepitgoing_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;
```

**3. Install Python driver:**
```bash
pip install mysqlclient
```

**4. Update settings:**

Add to your `.env` file:
```bash
DATABASE_URL=mysql://keepitgoing_user:your_secure_password@localhost:3306/keepitgoing
```

Or configure directly in settings:
```python
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'keepitgoing',
        'USER': 'keepitgoing_user',
        'PASSWORD': 'your_secure_password',
        'HOST': 'localhost',
        'PORT': '3306',
        'OPTIONS': {
            'charset': 'utf8mb4',
            'init_command': "SET sql_mode='STRICT_TRANS_TABLES'",
        },
    }
}
```

**5. Run migrations:**
```bash
python manage.py migrate
```

#### Database Migration Between Backends

To migrate data from one database to another:

**1. Export data from current database:**
```bash
python manage.py dumpdata --natural-foreign --natural-primary \
    -e contenttypes -e auth.Permission --indent 4 > data.json
```

**2. Update database settings to new backend**

**3. Run migrations on new database:**
```bash
python manage.py migrate --run-syncdb
```

**4. Import data:**
```bash
python manage.py loaddata data.json
```

```

Enable and start service:
```bash
sudo systemctl daemon-reload
sudo systemctl enable keepitgoing
sudo systemctl start keepitgoing
sudo systemctl status keepitgoing
```

#### Step 6: Celery Service (Optional, for background tasks)

```bash
sudo nano /etc/systemd/system/keepitgoing-celery.service
```

```ini
[Unit]
Description=KeepItGoing Celery Worker
After=network.target redis.service

[Service]
Type=forking
User=keepitgoing
Group=keepitgoing
WorkingDirectory=/home/keepitgoing/KeepItGoingServer
Environment="PATH=/home/keepitgoing/KeepItGoingServer/venv/bin"
Environment="DJANGO_SETTINGS_MODULE=config.settings.production"
EnvironmentFile=/home/keepitgoing/KeepItGoingServer/.env
ExecStart=/home/keepitgoing/KeepItGoingServer/venv/bin/celery -A config worker -l info

[Install]
WantedBy=multi-user.target
```

Enable and start:
```bash
sudo systemctl enable keepitgoing-celery
sudo systemctl start keepitgoing-celery
```

#### Step 7: Nginx Configuration

```bash
sudo nano /etc/nginx/sites-available/keepitgoing
```

Add the following configuration:

```nginx
upstream keepitgoing {
    server unix:/home/keepitgoing/KeepItGoingServer/gunicorn.sock fail_timeout=0;
}

server {
    listen 80;
    server_name tasks.firebugit.com;

    # Redirect HTTP to HTTPS
    return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl http2;
    server_name tasks.firebugit.com;

    # SSL Configuration
    ssl_certificate /etc/letsencrypt/live/tasks.firebugit.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/tasks.firebugit.com/privkey.pem;
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers on;

    # Security Headers
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-Content-Type-Options "nosniff" always;
    add_header X-XSS-Protection "1; mode=block" always;

    client_max_body_size 10M;

    # Static files
    location /static/ {
        alias /home/keepitgoing/KeepItGoingServer/staticfiles/;
        expires 30d;
        add_header Cache-Control "public, immutable";
    }

    # Media files
    location /media/ {
        alias /home/keepitgoing/KeepItGoingServer/media/;
        expires 7d;
    }

    # Application
    location / {
        proxy_pass http://keepitgoing;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_redirect off;

        # WebSocket support (if needed)
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
```

Enable site and restart nginx:
```bash
sudo ln -s /etc/nginx/sites-available/keepitgoing /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl restart nginx
```

#### Step 8: SSL Certificate (Let's Encrypt)

```bash
# Obtain SSL certificate
sudo certbot --nginx -d tasks.firebugit.com

# Certbot will automatically configure nginx
# Certificate auto-renews via cron
```

#### Step 9: Firewall Setup

```bash
# Allow SSH, HTTP, and HTTPS
sudo ufw allow OpenSSH
sudo ufw allow 'Nginx Full'
sudo ufw enable
sudo ufw status
```

#### Step 10: Initial Admin User and Approval

```bash
# Log in to the web interface at https://tasks.firebugit.com/admin
# Use the superuser credentials created in Step 3

# When new users register:
# 1. They receive verification email
# 2. After clicking verification link, you receive admin notification
# 3. Go to Admin > Users > select user(s) > Actions > "Approve selected users"
# 4. User receives approval email and can now log in
```

**Sync Protocol:**
- Client sends current state and last sync timestamp
- Server returns updates since last sync
- Server accepts client changes
- Conflict resolution handled server-side
