Create schemaless collection in mongoDB via mongoose

Question

I have the following mongoose schema records:

var mongoose = require('mongoose');

module.exports = mongoose.model('lM', {
    any     :   mongoose.Schema.Types.Mixed,
},'mlr');

And in my code I am doing as such:

var lm      = require('../server/models/records');

new lm().save(lmr);

Being that lmr is a JSON object.

This produces a mongodb database with the name I provided but the records inside that collection contain only:

_id: objectID
_v: 0

The JSON objects is nowhere to be seen. How can I get the JSON object inside the any wrapper in the schema?

Answer 1

var lm      = require('../server/models/records');

new lm({'any':lmr}).save();

In save() method pass callback function[optional] if you want to track error if any.

new lm({'any':lmr}).save(function(err){
   if(err) {
      console.log(err) 
   }else{
      console.log('saved')
   }
});

To create the schemaless collection you will have to set strict:false which is by default true. strict option ensures values passed to your model constructor that were not specified in schema do not get saved to the db.
