Maybe you should use "$set" in your update query like this :

<pre><code>{$set: {"name": req.body.name}}, // Update
</code></pre>

More information in <a href="https://docs.mongodb.com/manual/reference/operator/update/" rel="noreferrer">documentation</a>

EDIT

If it doesn't work, this is probably because there is no match with your filter.

Maybe you should try to match with an ObjectId like this :

<pre><code>var ObjectID = require('mongodb').ObjectID;

// In your request
{ "_id": ObjectID(req.body._id)}, // Filter
</code></pre>

Hope it helps.

Use <code>{$set: {"name": req.body.name}}</code> (as Sparw mentioned) to update the the properties you want in the document. Also, if the id that you pass as a parameter does not exists in the collection (and you want to create one with the same id) you can pass as a third parameter <code>{upsert: true}</code> to create one.

In your example:

<pre><code>connection((db) =&gt; {
 db.collection('orders')
 .updateOne(
 { "_id": req.body._id}, // Filter
 {$set: {"name": req.body.name}}, // Update
 {upsert: true} // add document with req.body._id if not exists 

 )
 .then((obj) =&gt; {
 console.log('Updated - ' + obj);
 res.redirect('orders')
 })
 .catch((err) =&gt; {
 console.log('Error: ' + err);
 }) })
</code></pre>

Tough @Spraw's answer is right for some cases, but sometimes it doesn't work. I think the convenient answer is <code>updateOne({_id: new ObjectID(req.body._id)}, {$set: {"name": req.body.name}}, callback)</code>.

the <code>_id</code> in <code>mongodb</code> is a <code>BSON</code> object and should be instantiated.

blocks|key|2607767|text|对我来说，在更新中传递对象之前，我必须删除"_id"/id字段。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2607768|或者它会说字段无效。|2607769|显然，在使用键作为引用时更新密钥并不是最好的做法。|2607770|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

For me, I have to delete the "_id"/id field before passing the object in the update.

Or it will say that the field is invalid.

Obviously, updated the key while you're using it as a reference isn't the best thing to do.

blocks|key|489760|text|正确的语法是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|489761|monDb.collection.updateOne(
++++{"_id":+ObjectId(req.params.id)},+

The correct syntax is:
<pre class="lang-js prettyprint-override"><code>monDb.collection.updateOne(
 {&quot;_id&quot;: ObjectId(req.params.id)}, 
 { $set: updateDoc }, 
 function(err, doc) {

UPDATE: Not <code>ObjectID</code> but <code>ObjectId</code>.

blocks|key|489765|text|我也遇到了这个问题，我用_id从req.body创建了一个常量|type|unstyled|depth|inlineStyleRanges|entityRanges|data|489766|const+{_id}+=+req.body++//pass+ID+user

I had this trouble too, I create a constant with _id from req.body
<pre><code>const {_id} = req.body //pass ID user
await User.updateOne({_id},{$set:data}, (err)=&gt;{
 if(err) return res.status(200).json({

 })

blocks|key|2607882|text|如果集合架构缺少要更新的字段，则可能发生这种情况。如果模式不严格(即，isStrict:+false)，请检查update操作符。在某些情况下，新的更新值可以与现有值相同。在这种情况下，猫鼬返回。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2607883|{+n:+1,+nModified:+0,+ok:+1+}|code-block|syntax|javascript|2607884|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

This might happen if the collection schema is missing the field that is to be updated. If the schema is not strict (i.e, isStrict: false), check the update operator. In some cases, the new update value can be same as existing value. In this case, mongoose returns
<pre><code>{ n: 1, nModified: 0, ok: 1 }

blocks|key|489787|text|在上面花了几个小时之后，我发现为了更新，我必须将id值转换为Integer，但是在只使用find的情况下，这并不是必需的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|489788|dbCollection.updateOne({+_id:+parseInt(reqBody.id)+}|offset|length|style|CODE|489789|entityMap^0|0|0|1G|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@$D|L|E|M|F|G]]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

after spending couple of hours on it I found out that for update I had to convert the id value to Integer, this was however not required where only find was being used
<code>dbCollection.updateOne({ _id: parseInt(reqBody.id) }</code>

I have the following code: 

<pre><code>connection((db) =&gt; {
 db.collection('orders')
 .updateOne(
 { "_id": req.body._id}, // Filter
 {"name": req.body.name} // Update
 )
 .then((obj) =&gt; {
 console.log('Updated - ' + obj);
 res.redirect('orders')
 })
 .catch((err) =&gt; {
 console.log('Error: ' + err);
 })
 })
</code></pre>

I want to change the name in the order but it doesn't update it.
The result in the console is 

<code>Updated - {"n":0,"nModified":0,"ok":1}</code>

I tried to read the documentation but it's horrific

EDIT: <code>{$set: {"name": req.body.name}},</code> didn't work as well

EDIT 2: The passed ID matches the _id in the database. Could it be a problem that I'm querying for plain text ID while in the database it is referred to as "ObjectId('5a42ja...')"
