Rails ActiveModelSerializer将两个相同类型模型的列表组合成一个序列化响应，具有不同的名称

我有一个rails api，其中我使用Active Model Serializers（版本0.10.6）来序列化json响应。

我有两个数组，在端点中都是“FeatureRequest”类型，返回用户发出的请求列表，以及第二个用户被标记的请求列表。理想情况下，我想将响应序列化为看起来像这样：

{ "my_requests" : { ...each serialized request... }, "tagged_requests" : { ...each serialized request, using the same serializer" } } 

有办法做到这一点吗？

这是我的相关控制器方法：

  def index_for_user user = User.includes(leagues: :feature_requests).find(params[:user_id]) # Find all requests that this user created @users_created_feature_requests = FeatureRequest.requests_for_user(user.id) @feature_requests_in_tagged_leagues = [] user.leagues.each do |league| @feature_requests_in_tagged_leagues << league.feature_requests end ...some serialized response here end 

在此代码中，两个列表是@users_created_feature_requests和@feature_requests_in_tagged_leagues

谢谢！

假设您有一个像FeatureRequestSerializer这样的序列化FeatureRequestSerializer ，您可以通过以下方式实现：

 def index_for_user user = ... users_created_feature_requests = ... feature_requests_in_tagged_leagues = user.leagues.map(&:feature_requests) # serialized response render json: { my_requests: serialized_resource(users_created_feature_requests) tagged_requests: serialized_resource(feature_requests_in_tagged_leagues) } end private def serialized_resource(collection, adapter = :attributes) ActiveModelSerializers::SerializableResource.new(collection, each_serializer: FeatureRequestSerializer, adapter: adapter ).as_json end
