Sequelize – SQL Server – 按关联表sorting

我有3个表，如user ， userProfile和userProfileImages 。 User与userPrfoile映射关系和userProfile与userProfile的映射关系一样多。

我需要在userProfileImages 通过查询来编写订单 ，我尝试了下面，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表的结果不是desc。

请给解决scheme

来自Sequelize官方文档：

  // 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'], 

通过引用上面的语法，像下面那样更新您的订单选项

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