私は2つの非常に単純なクラスを持っています:
class Contact
include Mongoid::Document
has_and_belongs_to_many :organizations, :class_name => 'Organization'
end
と
class Organization
include Mongoid::Document
has_and_belongs_to_many :relations, :class_name => 'Contact'
end
検証/保存時のエラーログは次のとおりです。
>> org = Organization.new
#<Organization _id: 5228ae3c1d41c8678c000001, relation_ids: nil, _type: "Organization">
>> org.valid?
org.valid?

ご覧のとおり、連絡先の検証は機能しますが、組織の検証は機能しません。さて、:inverse_of両側にオプションを追加しようとしましたが、エラーは残ります。どんな入力でも大歓迎です。
