NodsJs: TypeError: Cannot read properties of undefined (reading 'unscoped')

Question

我想通过使用 sequelize 从叶子 table 获取叶子数，但它给我错误未定义（读取 'unscoped'）。我正在使用 postgresql 和 NodeJS。

这是我的查询

router.get('/:userId', checkToken, authorize(), async (req, res) => {
try {
        const { params } = req;
        const { userId } = params;
 const leaveCounts = await db.leaves.unscoped().findAll({
            attributes: [[db.Sequelize.literal('SELECT count(distinct(id)) from leaves'), 'leaveCount']],
            where: {
                "userId": {
                    userId
                }
            },
            raw: true
        });
const data = {
            
            leaveCounts

        }

        res.status(200).json({
            data
        })
    }
    catch (e) {
        console.log("error in status: ", e)
        res.status(500).json({
            error: "Internal Server Error",
            status: false,
        })
    }
})

export default router;

错误：

error in status:  TypeError: Cannot read properties of undefined (reading 'unscoped')

邮递员回复：

{
    "error": "Internal Server Error",
    "status": false
}

请帮助如何做到这一点。

leaves 属性 in db 对象可能是 undefined。检查 db.leaves

的类型

ex) console.log(typeof db.leaves)

NodsJs: TypeError: Cannot read properties of undefined (reading 'unscoped')

NodsJs: TypeError: Cannot read properties of undefined (reading 'unscoped')

postgresql

node.js

sequelize.js
