Datamapper多对多关系

Question

文章有很多作者，编辑，翻译等。所有类人。 是否可以生成连接模型？或者，在这种情况下，解决方案是手动创建每个连接模型。

class Article
  include DataMapper::Resource

  property :id, Serial

  property :published_date, Date
  property :status, Enum[ :pending, :accepted, :declined, :modified, :new ], :default => :new
  property :visible, Boolean, :default  => false

  timestamps :at

  has n, :authors, 'Person', :through => Resource
end


class Person

  include DataMapper::Resource

  property :id, Serial

  property :name, String
  property :about, Text
  property :gender, Enum[ :male, :female ]
  property :birthday, Date

  timestamps :at

  has n, :articles, :through => Resource
end

Answer 1

看起来不可能。仅手动创建模型。
