mongoose – 引用子文档的ObjectId

ModelA中的ObjectId是否可以引用modelB中的子文档？ var C = new Schema({…}); var B = new Schema({c: [C]}); var A = new Schema({c: { type: ObjectId, ref: 'ModelB.ModelC' }); var Model_A = mongoose.model('ModelA', A); var Model_B = mongoose.model('ModelB', B); var Model_C = mongoose.model('ModelC', C);
