问题 I'm having an issue with limiting the level of associations serialized within an active model resource. For example: A Game has many Teams which has many Players class GameSerializer < ActiveModel::Serializer attributes :id has_many :teams end class TeamSerializer < ActiveModel::Serializer attributes :id has_many :players end class PlayerSerializer < ActiveModel::Serializer attributes :id, :name end When I retrieve the JSON for the Team, it includes all the players in a sub array, as desired.

问题 I am using active_model_serializers to create JSON for my Rails models. serializer class OptionSerializer < ActiveModel::Serializer self.root = false attributes :id def test_id object.id end end However, the to_json option seems to ignore the method added in OptionSerializer: OptionSerializer.new(Option.find(13)).to_json.html_safe expected output { "id": 13, "test_id": 13 } actual output { "id": 13 } I have reviewed this SO post, but that is the only post I can find where someone is

问题 I use rails (5.0.1) and active_model_serializers (0.10.2). I would like to somehow conditionally serialize the has_many associations: class Question < ApplicationRecord has_many :responses, :inverse_of => :question end class Response < ApplicationRecord belongs_to :question, :inverse_of => :responses end class QuestionSerializer < ActiveModel::Serializer attributes :id, :title, :created_at, :updated_at has_many :responses end class ResponseSerializer < ActiveModel::Serializer attributes :id,

问题 I have a Active Model Serializer that has the following: class API::DashboardSerializer < ActiveModel::Serializer attributes :id, :name, :special def special x = object.check_ins.first prev = x.prev_ci_with_weigh_in end end where special returns a record of class CheckIn and I'd like it to use the CheckInSerailizer for that record. How can I force it to use the CheckInSerializer in special ? 回答1: Remove special from attributes and then try has_one or belongs_to , described in this Guide, like

问题 I have a rails api, in which I'm using Active Model Serializers (version 0.10.6) to serializer json responses. I have two arrays, both are of type "FeatureRequest" in an endpoint that returns a list of requests a user has made, and a second list of requests that a user is tagged in.

问题 I am using active_model_serializers and ember.js. One of my models has a date attribute. In rails date attributes are serialized in the format of "YYYY-MM-DD".
