Question

我想编写一个查询来更新单个查询中的多个文档，请建议我可行的方法。

以下是我的mongo文档。

[
    {
        "_id" : ObjectId("5b0f0a2ca1f6633032c204cd"),
        "parent_id" : ObjectId("5b0f09e1a1f6633032c204cc"),
        "name" : "ABC",
        "userType": "admin"
    },
    {
        "_id" : ObjectId("5b0f0a2ca1f6633032c204ce"),
        "parent_id" : ObjectId("5b0f09e1a1f6633032c204cc"),
        "name" : "DEF",
        "userType": "admin"
    },
    {
        "_id" : ObjectId("5b0f0a2ca1f6633032c204cf"),
        "parent_id" : ObjectId("5b0f09e1a1f6633032c204cc"),
        "name" : "GHI",
        "userType": "admin"
    },
    {
        "_id" : ObjectId("5b0f0a2ca1f6633032c204d0"),
        "parent_id" : ObjectId("5b0f09e1a1f6633032c204cc"),
        "name" : "XYZ",
        "userType": "admin"
    }
]

我一直在跟踪代码中更新的对象，如何通过查询在数据库中更新该对象。

[
    {
        "_id" : ObjectId("5b0f0a2ca1f6633032c204cd"),
        "parent_id" : ObjectId("5b0f09e1a1f6633032c204cc"),
        "name" : "ABC123",
        "color":"red"
        "userType": "admin"
    },
    {
        "_id" : ObjectId("5b0f0a2ca1f6633032c204ce"),
        "parent_id" : ObjectId("5b0f09e1a1f6633032c204cc"),
        "name" : "DEF123",
        "color":"blue"
        "userType": "admin"
    },
    {
        "_id" : ObjectId("5b0f0a2ca1f6633032c204cf"),
        "parent_id" : ObjectId("5b0f09e1a1f6633032c204cc"),
        "name" : "GHI123",
        "color":"green"
        "userType": "admin"
    },
    {
        "_id" : ObjectId("5b0f0a2ca1f6633032c204d0"),
        "parent_id" : ObjectId("5b0f09e1a1f6633032c204cc"),
        "name" : "XYZ123",
        "color":"rgb(14,256,12, 1)"
        "userType": "admin"
    }
]

请给我建议正确的方法，否则我们可以做到吗？

您基本上需要在mongodb中进行bulkWrite操作

const array = [
  {
    "_id" : ObjectId("5b0f0a2ca1f6633032c204cd"),
    "parent_id" : ObjectId("5b0f09e1a1f6633032c204cc"),
    "name" : "ABC123",
    "color":"red"
    "userType": "admin"
  },
  {
    "_id" : ObjectId("5b0f0a2ca1f6633032c204ce"),
    "parent_id" : ObjectId("5b0f09e1a1f6633032c204cc"),
    "name" : "DEF123",
    "color":"blue"
    "userType": "admin"
  },
  {
    "_id" : ObjectId("5b0f0a2ca1f6633032c204cf"),
    "parent_id" : ObjectId("5b0f09e1a1f6633032c204cc"),
    "name" : "GHI123",
    "color":"green"
    "userType": "admin"
  },
  {
    "_id" : ObjectId("5b0f0a2ca1f6633032c204d0"),
    "parent_id" : ObjectId("5b0f09e1a1f6633032c204cc"),
    "name" : "XYZ123",
    "color":"rgb(14,256,12, 1)"
    "userType": "admin"
  }
]

最后的查询

Model.bulkWrite(
  array.map((data) => 
    ({
      updateOne: {
        filter: { _id: data._id },
        update: { $set: data }
      }
    })
  )
})

Mongo-如何在单个查询中更新具有不同值的多个文档？
