问题 I know that Ember-Data is supposed to be compatible with Active Model Serializers by design, but they seem to be out of step on serializing has_many relationships with embedded IDs. For example, the serializer class PostSerializer < ActiveModel::Serializer embed :ids has_many :comments end produces the JSON { "post": { "comment_ids": [...] } } But the default configuration in Ember Data, App.Post = DS.Model.extend({ DS.hasMany('App.Comment'), }); App.Comment = DS.Model.extend(); expects the
