我有一个模型地址,如下所示

class Address
  include Mongoid::Document

  field :line1
  field :city
  # more fields like this

  embedded_in :user, :inverse_of => :permanent_address
  embedded_in :user, :inverse_of => :current_address
  embedded_in :college, :inverse_of => :address
end

有模型学院和用户嵌入地址

class College
  include Mongoid::Document

  references_many :users
  embeds_one :address

  # some fields and more code
end


class User
  include Mongoid::Document

  referenced_in :college, :inverse_of => :users  

  embeds_one :permanent_address, :class_name => "Address"
  embeds_one :current_address, :class_name => "Address"

  # fields and more code
end

我在上面的设置中遇到了一些问题.我正在使用单个表单来询问当前和永久地址以及更多信息,但只有current_address被保存,而且我在permanent_address中填充的数据也是如此.
