Instance Method Details

#money_methods(*args) ⇒ Object

Takes a list of methods that the base object wants to be able to use to display with Spree::Money, and turns them into display_* methods. Intended to help clean up some of the presentational logic that exists at the model layer.

Examples

Decorate a method, with the default option of using the base object’s currency

extend Spree::DisplayMoney
money_methods :tax_amount, :price

Decorate a method, but with some additional options

extend Spree::DisplayMoney
money_methods tax_amount: { currency: "CAD", no_cents: true }, :price

Use generated method with the same arguments as in wrapped method

def tax_amount(order, country)
display_tax_amount(order, country)
