更新所有在Mongoose中不具有相同名称的字段(Update All Fields which is don't have the same name in Mongoose)

 我试图根据req.body更新Document中的所有字段。 
 
 在这种情况下，Schema没有在Mongoose中定义。 所以，我可以自由填充将要发布到模式中的内容 
 
 例如，我在Document中有2个这样的Scheme： 
 
 模式1： 
 
{
 "name": {
  "type": "text",
  "value": "Afdallah"
 },
 "item": {
  "type": "text",
  "value": "Books"
 }
}
 
 另一个就是这样 
 
 模式2： 
 
{
 "name": {
  "type": "text",
  "value": "Afdallah"
 },
 "email": {
  "type": "email",
  "value": "afdallah.war@gmail.com"
 }
}
 
 我的问题是，如何更新所有领域时，他们没有相同的字段名称？ 
 
 我尝试这样更新字段。 
 
const output = await Order.findOne({ _id: req.params.id });
try {
  output.set(req.body);
  await output.save();
  res.send("Success Update");
} catch (err) {
  res.status(422).send(err);
} 

I'm trying to update all fields in Document based on req.body. 
 
In this case, the Schema are not defined in Mongoose. So, I can fill freely what will be in post to schema
 
For example, I've 2 Scheme like this in the Document:
 
Schema 1:
 
{
 "name": {
  "type": "text",
  "value": "Afdallah"
 },
 "item": {
  "type": "text",
  "value": "Books"
 }
}
 
And the other is like this
 
Schema 2:
 
{
 "name": {
  "type": "text",
  "value": "Afdallah"
 },
 "email": {
  "type": "email",
  "value": "afdallah.war@gmail.com"
 }
}
 
My question is, how to update all fields when they don't have same fields name?
 
I've try like this to update the fields.
 
const output = await Order.findOne({ _id: req.params.id });
try {
  output.set(req.body);
  await output.save();
  res.send("Success Update");
} catch (err) {
  res.status(422).send(err);
}
