Error: the update operation document must contain atomic operators, when running updateOne
提问by Tim
In my collection, there is only one document.
在我的收藏中，只有一份文件。
> db.c20160712.find()
{ "_id" : ObjectId("57ab909791c3b3a393e9e277"), "Dimension_id" : 2, "Attribute" : "good", "Hour" : "20160712_06", "Frequency_count" : 100
I want to run updateOneto replace the document with another one. But why is there Error: the update operation document must contain atomic operators?
我想运行updateOne以用另一个文档替换该文档。但为什么会出现Error: the update operation document must contain atomic operators？
> db.c20160712.updateOne( { "Attribute" : "good"}, {"Type" : "DVD", "Title" : "Matrix, The", "Released" : 1999, "Genre" : "Action"}, { upsert: true} )

I believe this was changed as a side-effect of introducing the updateOne()method in addition to update()and updateMany()as somewhat of a safeguard to prevent user's from accidentally overriding an entire document.
我相信这是作为引入该updateOne()方法的副作用而改变的，update()并且updateMany()在某种程度上是为了防止用户意外覆盖整个文档。
You can use the replaceOne()method instead, or an update()without specifying multi:true.
您可以改用该replaceOne()方法，或者update()不指定multi:true.

You should use this code because I was also facing the same problem and then I used this code:
您应该使用此代码，因为我也遇到了同样的问题，然后我使用了此代码：
updateOne(
{ _id: new ObjectID(req.params.id) },
{ $set: { title: req.body.bookName, author: req.body.authorName } },
{ upsert: true }
)
and you should also define ObjectIDotherwise the problem will occur again....
并且您还应该定义ObjectID否则问题将再次发生....
const ObjectID = require('mongodb').ObjectID;
const ObjectID = require('mongodb').ObjectID;

You did the same mistake as I did. Upon going through the docs I realized the syntax is wrong. Try:
你和我犯了同样的错误。在浏览文档时，我意识到语法是错误的。尝试：
db.c20160712.updateOne(
{ "Attribute" : "good"},
{"Type" : "DVD", "Title" : "Matrix, The", "Released" : 1999, "Genre" : "Action"},
{ upsert: true}
)
