express - sequelize创建db记录后如何从响应中删除json元素？

Question

使用 sequelize，我可以使用 product modek 在我的数据库中创建一个 Product，但我想编辑 json 响应，删除 updatedAt 和 createdAt 元素。我该怎么做？

我的代码:

router.post('/products', (req, res, next) => {
    Product.create({
        name: req.body.name,
        price: req.body.price
    }).then(
        product => res.status(200)
            .json(product)
    )
});

使用此主体调用 localhost:3000/products 时:

{
    "name": "A Book",
    "price": 10.99,
}

我得到这个回应:

{
    "id": 8,
    "name": "A Book",
    "price": 10.99,
    "updatedAt": "2018-06-26T20:09:38.643Z",  <-- Remove?
    "createdAt": "2018-06-26T20:09:38.643Z"   <-- Remove?
}

Answer 1

尝试使用 lodash pick()。

如果你的回答是

{
    "id": 8,
    "name": "A Book",
    "price": 10.99,
    "updatedAt": "2018-06-26T20:09:38.643Z",
    "createdAt": "2018-06-26T20:09:38.643Z"
}

试试吧，var result = _.pick(response, ["name", "price"]);

router.post('/products', (req, res, next) => {
    Product.create({
        name: req.body.name,
        price: req.body.price
    }).then(
        product => 
            var result = _.pick(response, ["name", "price"]);
            res.status(200).json(result)
    )
});
