How to avoid insert empty record in mongodb using mongoose

Question

In my script i can create a new collection in mongodb but default one empty record is inserting so how to avoid that.

model.js:

 /* model.js */
 'use strict';

 var mongoose = require('mongoose'),
 Schema = mongoose.Schema;


 function dynamicModel(suffix) {
   var addressSchema = new Schema({

    product_name: {
        type: String
    }

   }); 
   return mongoose.model(suffix, addressSchema); 
  } 
  module.exports = dynamicModel;

data.controller.js:

      var NewModel = require(path.resolve('./models/model.js'))(collectionName);
      NewModel.create({ category: 1, title: 'Minion' }, function(err, doc) {

      });

after created new collection I am seeing like this:

  _id:ObjectId("5eceb362d538901accc0fefe");
  __v:0

category and title attributes are not available in your Schema, that's why it's creating a collection with only _id and __v. — vishnu

The strict option is by default enabled in Schema. If you need to add extra fields that are not specified in Schema you can set the strict option to false. mongoosejs.com/docs/guide.html#strict — vishnu

You must define these attributes in your model.

 /* model.js */
 'use strict';

 var mongoose = require('mongoose'),
 Schema = mongoose.Schema;


 function dynamicModel(suffix) {
   var addressSchema = new Schema({

    product_name: {
        type: String,
    },
    category: {
       type: Number,
    },
    title: {
       type: String,
    }

   }); 
   return mongoose.model(suffix, addressSchema); 
  } 
  module.exports = dynamicModel;
