Sequelize - 嵌套在哪里？

Question

我有这个特定的代码，我想使用 sequelize 逻辑进行转换。我正在从 .NET 转换为 Node：

public async Task<IEnumerable<NotificationAppEntity>> GetPagged(NotificatioAppGetPaggedReq req, Guid userId)
        {
            var res = await Context.NotificationApp
                .Where(x => req.Types.Contains(x.NotificationAppTypeId))
                .Include(x => x.CreatedBy).ThenInclude(x => x.UserPics)
                .Include(x => x.Comment)
                .Include(x => x.Task)
                .Include(x => x.Goal)
                .Include(x => x.NotificationAppType)
                .Include(x => x.NotificationAppUserRead)
                .Where(x => x.Task.ProjectId == req.ProjectId.Value || x.Comment.ProjectId == req.ProjectId.Value ||x.Goal.ProjectId == req.ProjectId.Value)
                .OrderByDescending(x => x.CreatedAt)
                .Skip(req.PagingParameter.Skip)
                .Take(req.PagingParameter.Take)
                .ToListAsync();

            return res;
        }

问题是，我不知道为什么将 [Op.or]] 放在 include 键中会出错。到目前为止，这是我当前的代码：

async getPagged(userId, body) {
    const notificationApp = await db.NotificationApp.findAll({
        where: { NotificationAppTypeId: body.NotificationAppTypeId },
        offset: body.Skip,
        limit: body.Take,
        include: [
            {
                model: await db.User,
                attributes: { exclude: hideAttributes },
                as: 'CreatedBy',
                include: { model: await db.UserPic },
            },
            {
                model: await db.Comment,
            },
            {
                model: await db.Task,
            },
            {
                model: await db.Goal,
            },
            {
                model: await db.NotificationAppType,
            },
            {
                model: await db.NotificationAppUserRead,
            },
        ],
        order: [['CreatedAt', 'DESC']],
    });

    return notificationApp;
}

如果我在对象中放置一个 where: 键，Sequelize 会将其视为 WHERE .. AND .. WHERE .. AND .. 等等。是否可以在 include 中使用 WHERE .. OR .. WHERE .. OR ？任何帮助将不胜感激。

我不确定这是否是您想要的。因为我不熟悉.Net

但是...

如果你想把你的 [Op.or] 条件放在这样的地方...

SELECT *
FROM NotificationApp
left join Task on ~~
left join Comment on ~~ 
where NotificationAppTypeId = (value) 
AND (Task.ProjectId = ProjectId OR Comment.ProjectId = ProjectId OR... )

我认为这可能有效。

async getPagged(userId, body) {
    const notificationApp = await db.NotificationApp.findAll({
        where: { 
            NotificationAppTypeId: body.NotificationAppTypeId,
            [Op.or] : [ 
           {'$Task.ProjectId$' : ProjectId},
           {'$Comment.ProjectId$' : ProjectId},
           ...your conditions
            ]
        },
        offset: body.Skip,
        limit: body.Take,
        include: [
            {
                model: await db.User,
                attributes: { exclude: hideAttributes },
                as: 'CreatedBy',
                include: { model: await db.UserPic },
            },
            {
                model: await db.Comment,
            },
            {
                model: await db.Task,
            },
            {
                model: await db.Goal,
            },
            {
                model: await db.NotificationAppType,
            },
            {
                model: await db.NotificationAppUserRead,
            },
        ],
        order: [['CreatedAt', 'DESC']],
    });

    return notificationApp;
}
