在限制结果和包括相关模型时,我遇到了Sequelize的问题.

以下产生正确的结果,限制为10并正确排序.

Visit.findAll({
  limit: 10,
  order: 'updatedAt DESC',
}).success(function(visits) {
  res.jsonp(visits);
}).failure(function(err) {
  res.jsonp(err);
})

SQL

SELECT * FROM `Visits` ORDER BY updatedAt DESC LIMIT 10;

但是当我添加一个关联时,它突然限制了子查询,因此排序从未发生,因为结果集有限.

Visit.findAll({
  limit: 10,
  order: 'updatedAt DESC',
  include: [
    { model: Account, required: true }
  ]
}).success(function(visits) {
  res.jsonp(visits);
}).failure(function(err) {
  res.jsonp(err);
})

SQL

SELECT 
  `Visits`.* 
FROM 
  (SELECT 
    `Visits`.*, `Account`.`id` AS `Account.id`, `Account`.`email` AS `Account.email`, `Account`.`password` AS `Account.password`, `Account`.`role` AS `Account.role`, `Account`.`active` AS `Account.active`, `Account`.`createdAt` AS `Account.createdAt`, `Account`.`updatedAt` AS `Account.updatedAt`, `Account`.`practice_id` AS `Account.practice_id`

我正在尝试使用 Sequelize ORM 的功能，该功能允许从包含的模型中引用嵌套列（请参阅Sequelize 文档：顶层的复杂 where 子句）。在文档中它指出，我可以使用$nested.column$语法。

以下是我试图做的：

let where = { memberId };
if (req.query.search) {
  const like = { [Op.like]: `%${req.query.search}%` };
  where = {
    ...where,
    [Op.or]: [
      { '$bookItem.serial$': like },
      { '$bookItem.book.name$': like },
      { '$bookItem.book.ISBNCode$': like },
    ],
  };
}

const options = {
  where,
  include: [
    {
      model: models.BookItem,
      as: 'bookItem',
      required: false,
      include: [
        {
          model: models.Book,
          as: 'book',
          attributes,
          required: false,
        },
      ],
    },
  ],
});
