Advanced Features

CurrencyConverter Class

For more control and batch operations:


from django_cfg.modules.django_currency import CurrencyConverter
 
converter = CurrencyConverter(
    max_workers=10,  # Parallel threads
    max_retries=3,   # Retry attempts
    retry_delay=1.0  # Delay between retries (seconds)
)
 
# Batch conversions
rates = converter.get_multiple_rates(
    base_currency="USD",
    target_currencies=["EUR", "GBP", "JPY", "BTC"]
)

Caching Strategy

The module uses intelligent caching to reduce API calls:


# First call - fetches from API
rate1 = convert_currency(100, "USD", "EUR")
 
# Second call (within cache period) - uses cached value
rate2 = convert_currency(100, "USD", "EUR")  # Instant!
