具有多个序列化器轨道的序列化器中的数组

Question

处理后得到数组。

gem 'active_model_serializers'

现在我想用serializer发送json格式的数据。

但是当我调用序列化程序时，它不会因为 Array 而获取对象。

控制器 -

def index
  question = user.questions.available 
  answer = user.where(:answer => params[:ans])
  render :json => {:qust => question, :each_serializer => QuestionSerializer,
                   :ans => answer, :each_serializer => AnswerSerializer}
end

question_serializer.rb

class QuestionSerializer < ActiveModel::Serializer
  attributes :id, :question, :type
end

answer_serializer.rb

class AnswerSerializer < ActiveModel::Serializer
  attributes :id, :answer, :date

  def date
   object.date = "..."
  end
end

Answer 1

或者像这样：

options        = {each_serializer: QuestionSerializer}
user_questions = user.questions.available 
questions      = ActiveModelSerializers::SerializableResource.new(user_questions, options)

render json: {
   qust: questions.as_json
}

Answer 2

试试这个：

render json: {
  qust: ActiveModel::ArraySerializer.new(question, each_serializer: QuestionSerializer),
  ans: ActiveModel::ArraySerializer.new(answer, each_serializer: AnswerSerializer),
}

旁白：

• 注意您的命名，在处理集合时使用复数。
• answer = user.where(:answer => params[:ans]) 看起来很糟糕
