node.js - 如何在 Mongoose 中填充嵌套实体？

Question

我有以下 Mongoose 模式结构

userSchema = new Schema({
    roles: [
        role: {type: Schema.Types.ObjectId, ref: 'Role' }
    ]
})

rolesSchema = new Schema({
  name: String,
  roleEntities: [
    {
      entity : {type: Schema.Types.ObjectId, ref: 'RoleEntity' },
      abilities : [{type: Schema.Types.ObjectId, ref: 'Ability' }]
    }
  ]
}

roleEntitiesSchema = new Schema({
  name: String
})

abilitiesSchema = new Schema({
  name: String
})

如何在 USER 模型上进行查找时填充所有这些嵌套文档？

我尝试如下使用填充

User.find(ctx.request.query).populate(
      {path: 'roles.role'
      ,populate: { path: 'roleEntities.entity'}
    }).
    exec()

但它没有解析 roleEntities.entity

您可以尝试链接填充操作

User.find()
.populate("roles.role")
.populate("roles.role.roleEntities.entity")
