How do I add data to existing user in mongoose schema from a running express app - Dave Macfarland authentication course

I completed Dave's authentication with express and mongo course and I wanted to continue with the project by adding info to an existing user but I'm stuck. After registering a user, I want the logged in user to be able to answer questions and those answers be added to their schema, then displayed on their profile page. I cannot figure it out. Here is some of the code

//models/user.js
var UserSchema = new mongoose.Schema({
    email: {
      type: String,
      unique: true,
      required: true,
      trim: true
    },
    userName: {
      type: String,
      required: true,
      trim: true
    },
    name: {
      type: String,
      required: true,
      trim: true
    },
    favoriteBook: {
      type: String,
      required: true,
      trim: true
    },
    password: {
      type: String,
      required: true
    }
});
var User = mongoose.model('User', UserSchema);
module.exports = User;


// index.js
// GET /user-survey
router.get('/user-survey', function(req, res, next) {
  return res.render('user-survey', { title: 'User Survey' });
});

// POST /user-survey
router.post('/user-survey', function(req, res, next) {
  /*

  User.update(query, { surveyanswer1: 'Some personal information' };
  */

Thanks!

Hey Ryan Morales, I got your question and if you want to implement a functionality to make logged in users able to answer the questions available in the page and then display all the question with answer in a user profile.

So here are the steps for this :

Make user answer the question only when they are logged in.So you can create a middleware for this.

Add another property in your schema i.e. questions.Look something like this

              questions        : [{
                         question : {type:String,trim:true},
                                             answer   : {type:String,trim:true}
                    }]

And when user submitting the answer you can easily find the user in the database and update the record.

function(data,callback){
            User.findOneAndUpdate(
                {_id:req.user._id},
                {$push:
                    { 
                        questions : {
                                question : data.question,
                                                    answer   : data.answer
                             }
                    }
                },
                (err,user) => {
                    if(err) res.send({msg:"Something went wrong" ,success:false});
                    if(user) res.send({msg:"Data Saved",post:data,success:true});
                }
            );
        }

When someone make request to profile page find the user and get all the fields you want to display and print those details on a page.
