## 💡 Usage Examples

### Using Excel Export
```python
# In any template with export functionality:
<div class="export-buttons">
    <a href="{{ url_for('reports.export_csv', start_date=start_date, end_date=end_date) }}" 
       class="btn btn-primary">
        <i class="fas fa-file-csv"></i> CSV
    </a>
    <a href="{{ url_for('reports.export_excel', start_date=start_date, end_date=end_date) }}" 
       class="btn btn-success">
        <i class="fas fa-file-excel"></i> Excel
    </a>
</div>
```

### Logging Activity
```python
from app.models import Activity

# When creating something:
Activity.log(
    user_id=current_user.id,
    action='created',
    entity_type='time_entry',
    entity_id=entry.id,
    description=f'Started timer for {project.name}'
)

# When updating:
Activity.log(
    user_id=current_user.id,
    action='updated',
    entity_type='invoice',
    entity_id=invoice.id,
    entity_name=invoice.invoice_number,
    description=f'Updated invoice status to {new_status}',
    metadata={'old_status': old_status, 'new_status': new_status}
)
```

### Sending Emails
```python
from app.utils.email import send_overdue_invoice_notification

# For overdue invoices (automated):
send_overdue_invoice_notification(invoice, user)

# For task assignments:
from app.utils.email import send_task_assigned_notification
send_task_assigned_notification(task, assigned_user, current_user)
```

```

**Emails not sending:**
- Check MAIL_SERVER configuration in .env
- Verify SMTP credentials
- Check firewall/port 587 access
- Look at logs/timetracker.log

**Excel export error:**
