按顺序在嵌套的加载中继续不工作

我有四个型号的Tehsil，Ilr，Patwar和Villages。 和他们的联系是

Tehsil – > 1：m – > Ilr – > 1：m – > Patwar – > 1：m – >村庄

我想要在我所有的四个模型上应用顺序。

查询：

var tehsilQuery = { include: [{ model: Ilr, as: 'GirdawariKanoongo', include: [{ model: Patwar, as: 'GirdawariPatwar', include: [{ model: Villages, as: 'GirdawariVillages', }] }] }], order: [ ['tehsil_name', 'ASC'], [ {model: Ilr, as: 'GirdawariKanoongo'}, 'kanoongo_name', 'ASC'], [ {model: Patwar, as: 'GirdawariPatwar'}, 'patwar_area', 'ASC'], [ {model: Villages, as: 'GirdawariVillages'}, 'village_name', 'ASC'], ] }; return Tehsils.findAll(tehsilQuery); [Error: 'girdawari_patwar' in order / group clause is not valid association] 

如果我从order删除了Patwar和Villages （lat两个模型）， order by正在工作。

Answer 1

我解决了它。 以下是order外观：

 order: [ 'tehsil_name', 'GirdawariKanoongo.kanoongo_name', 'GirdawariKanoongo.GirdawariPatwar.patwar_area', 'GirdawariKanoongo.GirdawariPatwar.GirdawariVillages.village_name' ] 

我所要做的就是：使用as关联表并链接它们，然后按column_name应用该order 。

Answer 2

另一个嵌套sorting的例子：

 order: [ [ { model: chapterModel, as: 'Chapters' }, 'createdAt', 'ASC'], [ { model: chapterModel, as: 'Chapters' }, { model: partModel, as: 'Parts' }, 'createdAt', 'ASC'] ], 

部分和章节有M：1的关系。
