그래서 내가 Datamapper (이것은 루비 /시나 프로젝트에)에 의해 생성 된 클래스 '범위'가 있습니다: 인수의 잘못된 번호 (2..3 1) (하면 ArgumentError)
class Range
include DataMapper::Resource
#properties
property :id, Serial, :key => true
property :default_gateway, String
property :subnetmask, String
property :main_ip, String
property :backup_ip, String
property :dhcp, String
#relations
belongs_to :vlan, :required => true
has n, :dhcp
end #class Range
또한 메인 클래스에서 호출하는 'initdata'파일이 있습니다. 이 파일의 일부는 일부 더미 데이터로 데이터베이스를 채 웁니다. 문제는 Ranges 클래스에서 ArgumentError를 제공합니다.
Initdata 루비 파일 :
#CREATE RANGES
if Range.count == 0
puts '----- ADDING RANGES -----'
range1 = Range.first_or_create(:default_gateway => '10.1.2.44', :subnetmask => '0.0.255.255', :main_ip => '10.1.0.1', :backup_ip => '10.1.0.2', :dhcp => '192.168.1.2', :vlan_id => 1)
range1.errors.each do |error|
puts error
end
end
내가 터미널에서 실행할 때 나는 다음과 같은 오류가 발생합니다 :

사람이 내가 잘못 일을 할 수있는 어떤 생각을 가지고 있습니까? 나는 그것을 찾았지만, 대부분의 솔루션은 사람들이 자신의 '초기화'함수를 작성했기 때문에 나의 경우와 같이 이미 DataMapper에 정의되어있다.
