Question

我要查找的内容是，首先选择包含我的搜索参数的评论，它将返回postId，然后选择包含所有评论的整个帖子，包括我们使用搜索参数搜索过的评论！

app.get('/search_', (req, res, next) => {
    var search = req.query.search;

comment.findAll({
        attributes: ['PostId'],
        where: {
            the_comments: {
                [Op.like]: `%${search}%`
            }
        }
    })
    .then(data => {
        var array = [ ];
        for (var x in data) {
            console.log(data[x].PostId);
            array.push(data[x].PostId);
        }
        console.log(array);
        Post.findAll({
                include: [
                    {
                        model: comment
                    }
                ],
                where: {
                    id: {
                        [Op. in]: [array]
                    }
                }
            })
            .then(result => {
                res.json(result);
         })
    })

您可以尝试一下。

Post.findAll({
    include: [
        {
            model: comment,
            required: true,
            where: {
                    the_comments: {
                                    [Op.like]: `%${search}%`
                                  }
                   }
        }
    ]
})
