Question

我在使用ActiveModelSerializer时遇到问题。

模型test.rb：

class Test < ActiveModel::Serializer
  attr_accessor :id, :userName, :lista, :test2

  def initialize params = {}
    @lista = Array.new
    @test2 = Array.new
    params.each { |key, value| send "#{key}=", value }
  end
end

模型test2.rb：

class Test2 < ActiveModel::Serializer
  attr_accessor :id, :userName

  def initialize params = {}
    params.each { |key, value| send "#{key}=", value }
  end
end

test_serializer.rb：

class TestSerializer < ActiveModel::Serializer
  attributes :id, :userName, :lista
  attributes :test2

  public

  def test2
    Test2Serializer.new(object.test2).as_json
  end
end

test2_serializer.rb：

class Test2Serializer < ActiveModel::Serializer
  attributes :id, :userName
end

我收到一个错误：

NoMethodError (undefined methodread_attribute_for_serialization’ for #Array:0x00007f1bb52da460):

调试代码后，我发现异常来自此行：

object.read_attribute_for_serialization(attr)

在变量对象中是一个数组。我认为应该是对象。所以我试图改变

Test2Serializer.new(object.test2).as_json

oto

json: object.test2, each_serializer: Test2Serializer

或：

object.test2, each_serializer: Test2Serializer

那没有用。谁能帮我吗？
