我有一个庞大而复杂的用户模型,它看起来是这样的:无法摧毁父对象
class User
class Link
include DataMapper::Resource
property :id, Serial, :key => false
belongs_to :follower, :model => 'User', :key => true
belongs_to :followed, :model => 'User', :key => true
end
include DataMapper::Resource
property :id, Serial
property :username, String, :required => true
has n, :links_to_followers, :model => 'User::Link', :child_key => [:followed_id]
has n, :links_to_followed, :model => 'User::Link', :child_key => [:follower_id]
has n, :comments
has 1, :profile_image
end
我的问题是,DataMapper的是不是让我摧毁它。我认为这是Datamapper不想销毁一个未销毁子对象的对象的结果,所以我放入了一个destroy_deep方法,该方法调用destroy_to_followers,links_to_followed,底层注释和配置文件图像(这些都被正确销毁) 。
但是,即使我之后调用user.destroy,用户也不会被销毁。没有任何类型的错误消息。是否有某种我缺少的级联删除命令?
