## Usage

### Basic Usage

```bash
python manage.py generate_test_data
```

This will create:
- 1 tenant
- 50 patients per tenant
- 100 appointments per tenant
- Associated clinical, financial, and communication records

### Command Options

```bash
python manage.py generate_test_data [OPTIONS]
```

**Options:**

- `--tenants N`: Number of tenants to create (default: 1)
  ```bash
  python manage.py generate_test_data --tenants 2
  ```

- `--patients N`: Number of patients per tenant (default: 50)
  ```bash
  python manage.py generate_test_data --patients 100
  ```

- `--appointments N`: Number of appointments per tenant (default: 100)
  ```bash
  python manage.py generate_test_data --appointments 200
  ```

- `--clear`: Clear existing data before generating new data
  ```bash
  python manage.py generate_test_data --clear
  ```
  **⚠️ Warning**: This will delete all existing data except superuser accounts!

### Examples

**Generate data for a single tenant with default settings:**
```bash
python manage.py generate_test_data
```

**Generate data for multiple tenants:**
```bash
python manage.py generate_test_data --tenants 3 --patients 30 --appointments 80
```

**Clear existing data and generate fresh data:**
```bash
python manage.py generate_test_data --clear --patients 100 --appointments 200
```

**Generate large dataset for testing:**
```bash
python manage.py generate_test_data --patients 200 --appointments 500
```

## Data Characteristics

### Patient Demographics
- **Age Distribution**: Weighted towards children (therapy center context)
  - 60% children (2-12 years)
  - 25% teenagers (13-18 years)
  - 15% adults (19-60 years)

### Appointment Distribution
- **Time Range**: Past 3 months + next month
- **Status Distribution**:
  - Past appointments: 75% completed, 15% no-show, 10% cancelled
  - Today's appointments: Mix of confirmed, arrived, in-progress
  - Future appointments: 70% confirmed, 30% booked
- **Scheduling**: Excludes Saudi weekends (Friday & Saturday)

### Financial Data
- **Services**: 5 service types per clinic
- **Pricing**: Realistic Saudi healthcare pricing (200-400 SAR)
- **VAT**: 15% tax applied to all invoices
- **Insurance**: Mix of self-pay and insured patients

### Clinical Records
- Generated for completed appointments only
- Includes realistic vital signs and measurements
- Age-appropriate clinical data

## Dependencies

The command requires the following Python packages:
- `django` - Django framework
- `faker` - For generating fake data
- `phonenumbers` / `django-phonenumber-field` - For phone number handling

These should already be installed in your project environment.

## Output

The command provides detailed progress output:

## Notes

- All generated data is realistic and follows Saudi cultural norms
- Patient names are bilingual (English and Arabic)
- Phone numbers follow Saudi mobile format
- Addresses use real Saudi cities and districts
- Work schedules respect Saudi work week and prayer times
- Financial data uses SAR currency with proper VAT
- Clinical data is age-appropriate and realistic

## Troubleshooting

**Issue**: Command not found
```bash
python manage.py generate_test_data
# Error: No module named 'core.management.commands.generate_test_data'
```
**Solution**: Ensure the management command directory structure exists:
```
core/
  management/
    __init__.py
    commands/
      __init__.py
      generate_test_data.py
```

**Issue**: Import errors
```bash
# Error: No module named 'faker'
```
**Solution**: Install required dependencies:
```bash
pip install faker
```

**Issue**: Database errors
```bash
# Error: UNIQUE constraint failed
```
**Solution**: Use the `--clear` flag to clear existing data first:
```bash
python manage.py generate_test_data --clear
```

## Best Practices

1. **Development**: Use smaller datasets for faster generation
   ```bash
   python manage.py generate_test_data --patients 20 --appointments 40
   ```

2. **Testing**: Use moderate datasets
   ```bash
   python manage.py generate_test_data --patients 50 --appointments 100
   ```

3. **Demo**: Use larger datasets for realistic demos
   ```bash
   python manage.py generate_test_data --patients 200 --appointments 500
   ```

4. **Fresh Start**: Always use `--clear` when you want to reset data
   ```bash
   python manage.py generate_test_data --clear
   ```
