Postgresql Sequalize postgres-仅当金额大于零时添加金额

我正在寻找一个sequelize查询，这样我就需要一个表的总量。但是有一个条件，只有当它大于0时，才添加数量

await model.post.findAll({
    where: {
        type: 'random',
    },
    attributes: [
        'id',
        'createdAt',
        [Sequelize.fn('SUM', Sequelize.col('others.amount')), 'totalAmount'],
    ], include: [
        {
            model: model.other,
            attributes: [],
            required: false,
            duplicating: false,

        },
    ],
    order: [['createdAt', 'DESC']],
    offset: (args.page - 1) * args.limit,
    limit: args.limit,
    raw: true,
    group: ['posts.id'],
});

在上面的代码中，我只想在金额大于零时添加

others.amount

我该怎么做

var list = await db.Post.findAll({
    where: {
        type: 'random',
    },
    attributes: [
        'id',
        'createdAt',
        [Sequelize.fn('SUM', Sequelize.col('other.amount')), 'totalAmount'],
    ],
    include: [
        {
            model: db.Other,
            attributes: [],
            required: false,
            duplicating: false,
            as: 'other',
            where: {
                amount: { [Op.gte]: 0 } // grater than 0
            }
        },
    ],
    order: [['createdAt', 'DESC']],
    raw: true,
    group: ['Post.id'],
});
console.log(JSON.parse(JSON.stringify(list)))

添加了
