#resolve_currency_condition(attr, currency) ⇒ ActiveRecord::Relation

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

    the money attribute name

  • currency (String, Mint::Currency) —

    the currency code or object

Returns:

  • (ActiveRecord::Relation)

Raises:

  • (ArgumentError) —

    if the attribute is not a composite money attribute
