信封：无法读取帆中未定义的属性'id'.js

Question

Envelope:无法读取sails.js中未定义的属性"id"每当我有发送创建请求时，他们都会给我上面的错误，型号：Car.js

module.exports = {
  attributes: {
    name: {
      type: 'string',
      required: true,
      unique: true
    },
    engine: {
      type: 'String',
    },
    type: {
      type: 'String'
    },
    colors: {
      collection: 'color',
      via: 'car'
    }
  },
};

型号：Color.js

module.exports = {
  attributes: {
    color: {
      type: 'String',
      unique: true,
      required: true
    },
    car: {
      model: 'car',
      required: true
    }
  },
};

CarController.js

请尽快帮我bcz我有业余学习者在sails.js

create: async function (req, res) {
    let name = req.param('name');
    let engine = req.param('engine');
    let type = req.param('type');
  
    let colorName = req.param('color');
    if(!name){
      res.badRequest({err : 'invalid Name'});
    }
    if(!engine){
      res.badRequest({err : 'invalid Engine'});
    }
    if(!type){
      res.badRequest({err : 'invalid Type'});
    }
    if(!colorName){
      res.badRequest({err : 'invalid Color Name'});
    }

    await Car.create({
      name: name,
      engine: engine,
      type: type
    })
    .exec((err, newcar) => {
      if(err) {
        return res.serverError(err);
      }
      //Create New Color
        Color.create({
          color: colorName,
          car: newcar.id,
        })
        .exec((err, _color) => {
          if(err) {
            return res.serverError(err);
          }
        })
        res.send(newcar, _color);
    })
  },

这看起来像id错误，请尽快解决

在sails.js 中工作的查找

find: async(req, res) => {
            try{
              let doc = await db.collection('color').aggregate([
                {
                  $lookup: {
                    from: 'car',
                    localField: 'carID',
                    foreignField: 'carID',
                    as: 'Car'
                  }
                }
              ]).toArray();
              res.ok(doc);
            } catch (error) {
          return res.badRequest(error);
        }
      }
