mongodb将objectid添加到ID数组

Question

我有诗歌模式，该模式在字段名称'communities'下具有链接的objectid数组：

{ 
    _id: ObjectId("61659ef70e87b90018f7baa1"),
    schemaName: 'Poem',
    helps: [ ObjectId("5d15c609832d390c41ab6872") ],
    communities: 
      [ ObjectId("5eafbabaf0be6f0017303eb3"),
        ObjectId("5eba549a45bd9300170f6311") ],
}

我正在尝试使用UpdateOne和$ push向数组中添加一个新的Objectid：

db.poems.updateOne(
    {title: "My stillness"},
    {$push: {communities: {ObjectId: ('61f942b737bdc10018722539')}}}
)

添加新ID时，它不是正确的格式（另请参见MongoDB指南针的附件图像，以进一步清楚格式的差异）。如何调整我的updateOne/$ push方法以正确格式添加objectID？谢谢

{ 
    _id: ObjectId("61659ef70e87b90018f7baa1"),
    schemaName: 'Poem',
    helps: [ ObjectId("5d15c609832d390c41ab6872") ],
    communities: 
      [ ObjectId("5eafbabaf0be6f0017303eb3"),
        ObjectId("5eba549a45bd9300170f6311"),
        { ObjectId: '61f942b737bdc10018722539' } ],
}

您将键值对推入数组。

ObjectId: ('61f942b737bdc10018722539')

相反，应该是：

ObjectId('61f942b737bdc10018722539')

db.poems.updateOne(
  { title: "My stillness" },
  { $push: { communities: ObjectId('61f942b737bdc10018722539') } }
)
