sails.js - Sails 蓝图填充不工作？

Question

根据 this , 在创建与其他记录关联的新记录时，响应应包含填充的关联记录。

POST /pony
{
  "name": "Pinkie Pie",
  "pet": 1
}

响应应该是这样的

{
  "name": "Pinkie Pie",
  "pet": {
    "name": "Gummy",
    "id": 1
  },
  "id": 4,
  "createdAt": "2013-10-18T01:22:56.000Z",
  "updatedAt": "2013-11-26T22:54:19.951Z"
}

相反，我实际上得到了一个 "pet": 1作为回应。

我的步骤是这样的:

sails new test

sails generate api pony

sails generate api pet

添加 "name" : "string"两种型号

添加 "pet" : { "model" : "pet" }小马模型

我应该做些什么来让蓝图 api 填充 pet属性响应 pony创建还是我必须做另一个请求才能填充宠物？

默认情况下，blueprint在 create行动不做populateAll通过创建的任何新实例。看它是source code .

如果你想自动填充创建的内容，你应该覆盖默认 blueprint在 create行动，类似的东西。

create: function(req, res){
  var Model = actionUtil.parseModel(req);

  // Create data object (monolithic combination of all parameters)
  // Omit the blacklisted params (like JSONP callback param, etc.)
  var data = actionUtil.parseValues(req);


  // Create new instance of model using data from params
  Model.create(data).exec(function created (err, newInstance) {

    // Differentiate between waterline-originated validation errors
    // and serious underlying issues. Respond with badRequest if a
    // validation error is encountered, w/ validation info.
    if (err) return res.negotiate(err);

    // If we have the pubsub hook, use the model class's publish method
    // to notify all subscribers about the created item
    if (req._sails.hooks.pubsub) {
      if (req.isSocket) {
        Model.subscribe(req, newInstance);
        Model.introduce(newInstance);
      }
      Model.publishCreate(newInstance, !req.options.mirror && req);
    }

    // Send JSONP-friendly response if it's supported
    // populate it first
    Model
      .findOne({id:newInstance.id})
      .populateAll()
      .exec(function(err, populatedInstance){
        if (err) return res.negotiate(err);

        res.created(populatedInstance);
      });
  });
}
