Node.js 为什么sequelize只返回一个结果？

我在编写代码时遇到一些问题，以下是一些信息： 型号：

控制器：

此代码返回此结果（然后获取/news/0/1）：

但我的数据库里有5条新闻！ …然后我获取/news/0/5，我得到了这个：

[
    {
        "id": 1,
        "title": "First new",
        "slug": "demo:first_new",
        "body": "New 1. This is demo ^=^",
        "postedBy": 0,
        "createdAt": "2020-07-22T13:53:48.000Z",
        "updatedAt": "2020-07-22T13:53:48.000Z",
        "rate": [
            {
                "rate": "0.0000"
            }
        ]
    }
]

看，利率是无效的！它应该是-0.3333

有人能给我解释一下，为什么会发生这种情况，以及如何解决这个问题吗

router.get('/news/:from/:count', (req, res, next) => {
    if (Number.isInteger(Number(req.params.from)) && Number.isInteger(Number(req.params.count))) {
        models.news.findAll({
            offset: Number(req.params.from),
            limit: Number(req.params.count),
            include: [{
                as: 'rate',
                model: models.news_ratings,
                attributes: [
                    [sequelize.fn('AVG', sequelize.col('rating')), 'rate']
                ]
            }]
        })
        .then(response => {
            console.log(response)
            res.json(response)
        })
        .catch(err => {
            console.error(err)

            res.status(500).end()
        }) 
    } else next()
})
