MSG =

‘Money.zero` and it’s alias ‘empty`, with or without currency argument is removed in favour of the more explicit Money.new syntax. Supplying it with a real currency is preferred for additional currency safety checks.

If no currency was supplied, it defaults to Money::NULL_CURRENCY which was the default setting of Money.default_currency and should effectively be the same. The cop can be configured with a ReplacementCurrency in case that is more appropriate for your application.

Examples:


# bad
Money.zero

# good when configured with `ReplacementCurrency: CAD`
Money.new(0, 'CAD')
'Money.zero is removed, use `Money.new(0, %<currency>s)`.'
