Question

在我的rails应用程序中，我有2个“远程模型”。这些模型不是active_record模型，而是使用API提供的gem在API上检索。

我将哈希数据发送到库中，库以哈希的形式提供数据。我的问题更多是关于如何生成正确的哈希

我的问题可以用以下2个模型来说明;

remote_user.rb

this.quoteService.getQuotes().mergeMap( quotes => {
    // Do whatever you need to do with quotes
    return this.quoteService.getOptions()
}).subscribe( options => {
    // Do whatever you need with options
});

remote_adresse.rb

class RemoteUser
  include ActiveModel::Model
  include ActiveModel::Serialization

attr_accessor(
  :Name
  :Email
  ...)
end

def attributes{ 'Name'=> nil,'Email'=>nil .....}

attr_reader(:HeadquartersAdress)

def HeadquartersAddress=(data={})
if data.is_a? RemoteAdresse
  @HeadquartersAddress=data
else
  @HeadquartersAddress=RemoteAdresse.new(data)
end
end

测试：

class RemoteAdresse
  include ActiveModel::Model
  include ActiveModel::Serialization
  attr_accessor(
    :AddressLine1,
    :AddressLine2,
    :City,
    :Region,
    :PostalCode,
    :Country
  )

  def attributes
    {
      'AddressLine1'=>nil,
      'AddressLine2'=>nil,
      'City'=>nil,
      'Region'=>nil,
      'PostalCode'=>nil,
      'Country'=>nil
    }
  end
end

我更愿意：{“Name”=＆gt;“Foo”，“HeadquartersAddress”=＆gt; { “城市”= “新加坡”}}

嵌套对象（adresse）未序列化。我该怎么做才能使它序列化？

Answer 1

如果我没有完全弄错，你需要在serializable_hash电话中包含关联，如下所示：

test = RemoteUser.new Name: 'Foo'
test.HeadquartersAddress=RemoteAddress.new City: 'singapour'
test.serializable_hash(include: :HeadquarterAddress)

如果这不起作用，则始终可以覆盖read_attribute_for_serialization并将其调整为HeadquarterAddress属性。
