node.js - strongloop 在 afterRemote 方法中创建相关模型对象

Question

假设我有一个游戏场景。

一个游戏属于一个用户。

游戏.json:

{
  "name": "game",
  "base": "PersistedModel",
  "idInjection": true,
  "properties": {
    "beer_points_required": {
      "type": "number",
      "required": true
    },
    "total_points": {
      "type": "number",
      "required": true
    }
  },
  "validations": [],
  "relations": {
    "game_blngs_to_user": {
      "type": "belongsTo",
      "model": "user",
      "foreignKey": ""
    }
  },
  "acls": [],
  "methods": []
}

用户.json:

{
  "name": "user",
  "base": "User",
  "idInjection": true,
  "properties": {
    "last_game": {
      "type": "date",
      "required": false
    },
    "name": {
      "type": "string",
      "required": true
    }
  },
  "validations": [],
  "relations": {},
  "acls": [
    {
      "accessType": "READ",
      "principalType": "ROLE",
      "principalId": "$everyone",
      "permission": "ALLOW"
    }
  ],
  "methods": []
}

我试图在通过 CRUD 创建用户后以编程方式为用户创建游戏对象，因此在 user.js 中我有:

var config = require('../../server/config.json');
var path = require('path');
var app = require('../app');

module.exports = function(user) {

user.afterRemote('create', function(context, user) {
    console.log('> user.afterRemote triggered');

  //create a game for each user thats created
  var Game = app.models.game;
  game.create({game_blngs_to_userId: user.id, beer_points_required: 0, total_points: 0},function(err, res){
 if(err){
      console.log('\n\n>>err');
      console.log(err);
      next(err);
      return;
    }
    console.log(res);
  });
});

但是，这显然行不通，哈哈，所以我想知道如何真正实现我的目标。很长一段时间以来，我一直盯着强循环文档看，似乎他们的 api 的实际使用情况并没有很好的记录……至少在我看来是这样。谁能帮我解释一下这个？

也许，您在 afterRemote 回调中缺少第三个参数 - next 函数。

user.afterRemote('create', function(context, user, next) {
  ...
  var Game = app.models.game;
  game.create({game_blngs_to_userId: user.id, beer_points_required: 0, total_points: 0},function(err, res){
 if(err){
      console.log(err);
      next(err);
      return;
    }
    next() // countinue execution
  });
});
