Instance Method Details

#full_messages_with_gettext ⇒ Object

Returns all the full error messages in an array.

  • If the error messages include %fn, it returns formatted text such as “foo %fn” => “foo Field”

  • else, the error messages are prepended the field name such as “foo” => “Field foo” (Same as default behavior).

As L10n, first one is recommanded because the order of subject,verb and others are not same in languages.

#on_with_gettext(attribute) ⇒ Object

Returns error messages.

  • Returns nil, if no errors are associated with the specified attribute.

  • Returns the error message, if one error is associated with the specified attribute.

  • Returns an array of error messages, if more than one error is associated with the specified attribute.

And for GetText,

  • If the error messages include %fn, it returns formatted text such as “foo %fn” => “foo Field”

  • else, the error messages are prepended the field name such as “foo” => “foo” (Same as default behavior).

Note that this behaviour is different from full_messages.
