How to generate ObjectId() when manually inserting in Robo 3T?-CodePudding

I'm trying to generate ObjectId() when inserting manually in Robo 3T.

Code below seems doesn't work. I wanted every object inside TestArray have a unique id.

How do I generate ObjectId manually?

{
    "Name" : "Test",
    "TestArray" : [ 
        {
            "_id" : ObjectId(),
            "Name" : "Test"
        }
    ]
}

I have tried

x=ObjectId();

and it works fine for me

CodePudding user response：

Try:

 new ObjectId()

This will generate the objectId on client side

CodePudding user response：

You don't have to generate the _id, just don't that field in your insert query and mongo will automatically generate it for you.

Do it like this:

var TestArray = []    
for (let i = 0; i < 10; i  )
   TestArray.push({ "_id": ObjectId(), "Name": "Test" }) 

{
    "Name" : "Test",
    "TestArray" : TestArray
}
