具有多個串行器軌道的串行器中的陣列

Question

我在處理后得到數組。

gem 'active_model_serializers'

現在我想使用serializer以json格式發送數據。

但是當我調用序列化程序時，它不會因為Array而得到對象。

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

嘗試這個：

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

附言：

• 注意你的命名，在使用集合時使用復數。
• answer = user.where(:answer => params[:ans])看起來很糟糕

Answer 2

或者像這樣：

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

render json: {
   qust: questions.as_json
}
