通过mongoose REST显示引用的文档详细信息？

Question

我有一个包含ref字段的架构：

exports.metricSchema = new Schema({
    metricGroup: {type: mongoose.Schema.Types.ObjectId, ref: 'metricGroupSchema', required: true},
    metricType: {type: mongoose.Schema.Types.ObjectId, ref: 'metricTypeSchema', required: true},
    key: {unique: true, type: String, required: true},
    name: {type: String, required: true},
    description: String

});

我将它们定义并注册为：

var MetricGroupResource = apprest.resource = restful.model('MetricGroup', schemas.metricGroupSchema)
    .methods(defaultRestMethods);
MetricGroupResource.register(apprest, '/rest/metricgroup');

它将在mongoose REST中显示为：

{
"_id": "58a20f5f04ef5789d3ef8fb7",
"name": "Tangle Index",
"key": "TI",
"metricType": "58a20f43f1bbfe89c86bf602",
"metricGroup": "58a20f43f1bbfe89c86bf600",
"__v": 0
}

有没有办法让mongoose显示引用模型的详细信息而不构建自定义填充视图？

Answer 1

您可以使用populate函数，您可以阅读文档here

示例：

MyModel.find(query)
.populate(
    [
        {
            'path': 'metricGroup'
        },
        {
            'path': 'metricType'
        }
    ]
)
.exec(function (err, _array) {
  if (err) {
    console.log(err);
  }
  console.log(_array); //print array with metricGroup and metricType fields with details
});
