node.js - 在 Sequelize 中的嵌套急切加载中排序不起作用

Question

我有四个模型 Tehsil、Ilr、Patwar 和 Villages。 他们的关联是

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

我想在我的所有四个模型上应用 order by。

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 中删除 Patwar 和 Villages(lat 两个模型)，order by 就可以工作。

另一个使用嵌套排序的工作示例:

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

其中部分和章节具有 M:1 关系。
