javascript - Sequelize 和 Sequelize 层次结构 : How do I execute an accessor in a model getter?

Question

我在我的应用中使用 sequelize 和 sequelize-hierarchy，并部分定义了如下模型:

ancestors : {
    type: orm.Sequelize.VIRTUAL,
    get: function() { return 'TODO how return getAncestors here?' }
  }

在 getter 内部，如何访问 sequelize-hierarchy 提供的 getAncestors() 方法？

@leroydev 感谢您的记录;)

正如开发人员在该问题中对我所说:

I'm afraid this isn't possible. You'd need to load the ancestors first with include. A getter can't execute asynchronously, and therefore can't fetch the ancestors from the database. When you use include, it fetches them at the same time as the main query.

This is a limitation of Sequelize (actually I think quite a reasonable one). I'm afraid there's nothing I can do about it, so am closing this PR.
