In my collection, there is only one document.

> db.c20160712.find()
{ "_id" : ObjectId("57ab909791c3b3a393e9e277"), "Dimension_id" : 2, "Attribute" : "good", "Hour" : "20160712_06", "Frequency_count" : 100 

I want to run updateOne to replace the document with another one. But why is there 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 )

The second and third arguments in the above command comes from an example in The Definitive Guide to MongoDB: A complete guide to dealing with Big Data ...

My MongoDB is 3.2.

Wrong syntax for the second parameter. Please check the docs. It should be:

db.c20160712.updateOne(
 "Attribute" : "good" , 
 $set: "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.

You can use the replaceOne() method instead, or an update() without specifying multi:true.

You should use this code because I was also facing the same problem and then I used this code:

updateOne(
 _id: new ObjectID(req.params.id) ,
 $set: title: req.body.bookName, author: req.body.authorName ,
 upsert: true 
)

and you should also define ObjectID otherwise the problem will occur again....

const ObjectID = require('mongodb').ObjectID;
