Sequelize-SQL Server-关联表排序

Question

我有3个表，如user，userProfile和userProfileImages。User与userPrfoile尽可能多地userProfile映射，并且与userProfileImages尽可能多地映射。

我需要编写的查询顺序中userProfileImages，我尝试如下，但没有运气。

User.findById(uID, { 
include: [
   model: sequelize.models.userProfile
   as: userProfile,
   include: [
    {
      model: sequelize.models.userProfileImages,
      as: 'profileImages',

    }
   ],
    order: [[sequelize.models.userProfileImages.id, "desc"]]
  // order: [["id", "desc"]] --> Tried this way also no luck
] }

我得到了结果，但是userProfilePicture表的结果却不尽如人意。

请给解决方案

Answer 1

从Sequelize官方文档中：

    // Will order by an associated model's created_at using an association object. (preferred method)
    [Subtask.associations.Task, 'createdAt', 'DESC'],

    // Will order by a nested associated model's created_at using association objects. (preferred method)
    [Subtask.associations.Task, Task.associations.Project, 'createdAt', 'DESC'],

通过引用以上语法，如下更新您的订单选项

User.findById(uID, { 
    include: [
        model: sequelize.models.userProfile
        as: userProfile,
        include: [{
           model: sequelize.models.userProfileImages,
           as: 'profileImages',
        }],
        order: [['profileImages','id', 'desc']]
    ]
});

像下面这样关联更新您的订单

User.findById(uID, { 
include: [
    model: sequelize.models.userProfile,
    as: userProfile,        
    include: [{
       model: sequelize.models.userProfileImages,
       as: 'profileImages',
       separate:true
       order: [['id', 'desc']]
    }],
]});
