dm-validations package is silently broken by string interpolation issue

Reported by Dawid Marcin Grzesiak | December 18th, 2009 @ 03:54 PM


I have a problem with validations when I turn $DEBUG flag on.
I receive this exception: ArgumentError "too many arguments for format string".

In ruby when you run this code everything is ok:
"%s must be an integer" % ["Area", /\A[+-]?\d+\z/]

but try this:
$DEBUG=true; "%s must be an integer" % ["Area", /\A[+-]?\d+\z/]

The problem is in the context of:

def self.default_error_message(key, field, values)
field = Extlib::Inflection.humanize(field) @@default_error_messages[key] % [field,
values].flatten # BUG end

I've provided specs patch.

Kind regards,
