Sequelize - SQL Server - 关联表排序

我有3个表，如user,userProfile和userProfileImages。 User与userPrfoile的映射一样多，并且userProfile与userProfileImages映射的一样多。Sequelize - SQL Server - 关联表排序

我需要编写订单查询userProfileImages，我试过如下，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 
] }

我得到的结果，但userProfilePicture表的结果不符合递减。

请给予解决方案

请尝试使用单个数组而不是2d数组，如：[[“id”，“desc”]' – RaghavGarg

我试过了，但它不起作用。还有一件事，我还在第二个包含内做了一个映射。作为 –

按关键字排序也不附加在我的查询中。 –

从Sequelize官方文档：像

// 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'],

通过上面的语法参考，更新您的订单选项下面

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

    } 
    ], 
    order: [['profileImages','id', 'desc']] 
] }
