I'll try to keep it short and simple, The schema looks like below...

import mongoose from 'mongoose'

const QuestionSchema = mongoose.Schema({
    questionTitle: { type: String, required: " title"},
    questionBody: { type: String, required: "body"}
    userId: { type: String},
    askedOn: { type: Date, default: Date.now},
    Comment:[{
        commentBody: String,
        userCommented: String,
        userId: String,
        commentedOn: { type: Date, default: Date.now},
    }],
    answer: [{
        answerBody: String,
        userAnswered: String,
        userId: String,
        answeredOn: { type: Date, default: Date.now},
        Comment:[{                      
            commentBody:String,          ////
            userCommented: String,       ////
            userId: String,              ////  
            commentedOn: { type: Date, default: Date.now},         ////
        }]
    }]
})

export default mongoose.model("Question", QuestionSchema)

How do i fill data in the slashed part of code?? ( i.e comment section of answers) i wanted to pass answerId with the comment data, to somehow look for that answerId in whole schema and fill my data into this comment section

CodePudding user response：

You can do achieve this using $ and $push.

const updateTheCol =  await Question.updateOne(
 { "answer.userId": "user id" }, 
 { $push: { 
"answer.$.Comment": { 
  commentBody: "comment body", 
  userCommented: "user commented",
  userId: "user id" }
 } 
})
