Display total methods

The Spree::Order model includes a number of useful methods for displaying totals and balances:

display_outstanding_balance: The outstanding balance for the order, calculated by taking the total and subtracting the current payment_total.
display_item_total: The total of the line items on the order.
display_adjustment_total: The total of the adjustments on the order.
display_total: The order total.
display_total_available_store_credit: The total available store credit.
display_order_total_after_store_credit: The order total after store credit has been applied.
display_store_credit_remaining_after_capture: The amount of store credit remaining after an order payment has been captured.

By default, the following methods return Spree::Money objects configured with the order's currency symbol. For example:

@order.display_total.to_html 
# => "$10.99"

Because Spree::Money objects are based on the Ruby Money library, you can further change what information is displayed using its format method:

@order.display_total.format(with_currency: true)
# => "$10.99 USD"
