Updating arrays with empty fields in mongodb

I need help updating an array in my database which currently doesn't have any fields. Can anyone suggest a way to add fields to the existing empty array?

Schema

      const UserSchema = new Schema({
        User: [{

         Name:{
           type: String,
        },

        Email:{
           type: String,
        },

       }]
    })

The array is currently saved in the database but it's empty like this

saved database

      "id": 101,
      "User":[],

Below is the code I've used to update the array

           User.update({id: 101,},
             {
             $push:{
                 user:{
                      Name: "Kevin",
                      Email: "<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="266d43504f4866414b474f4a0845494b">[email protected]</a>",
                     },
                   }
             },(err, data)=>{
                console.log(data)
             })

However, upon running this code, the array doesn't seem to update. Can anyone provide guidance on how to resolve this issue?

Answer №1

db.getCollection('test2').update({
  "id": 101
},
{
  $push: {
    User: {
      $each: [
        {
          "name": "gibbs"
        }
      ]
    }
  }
})

Adding new data to an array using the $each operator. It is important to note that field names are case sensitive in MongoDB, so User should be capitalized.
