重组 Sequelize 结果

Question

我在 Sequelize 中制作了一个复杂的 findAll，其中包含很多 includes，就像这样。

const versions = yield Version.findAndCountAll({
  order: [['createdAt', 'DESC']],
  attributes: ['description', 'createdAt', 'id'],
  include: [{
    model: Section,
    attributes: ['slug'],
    where: { slug: section },
    include: [{
      model: Type,
      attributes: ['slug'],
      where: { slug: type },
      include: [{
        model: Group,
        attributes: ['slug'],
        where: { slug: group }
      }]
    }]
  }]
});

结果如下：

{
  "description": "Wow. Nice one.",
  "createdAt": "2016-04-11T23:05:15.736Z",
  "body": "hi",
  "id": 10,
  "Section": {
    "slug": "ttyl",
    "Type": {
      "slug": "Test",
      "Group": {
        "slug": "python2",
      }
    }
  }
}

它们嵌套的深度使结果有点令人不快。如果可能的话，我希望它更像这样

{
  "description": "Wow. Nice one.",
  "createdAt": "2016-04-11T23:05:15.736Z",
  "body": "hi",
  "id": 10,
  "Section": "ttyl",
  "Type": "Test",
  "Group": "python2"
}

这可能吗？

您可以通过设置 raw:true 将其展平到某种程度。 Raw true 将展平为 model.subproperty.property 等。include 'as' 选项允许您在这些属性上使用别名。但我不相信您可以自动完全重塑对象（至少我在文档中没有发现任何内容）。从上面的示例中，我相信最终您必须添加自己的映射步骤。

Model.findAndCountAll({
  ...
}).then(function(results){
     return results.map(function(items){
         //map into another "object'
         //or into anonymous {};
     });
});
