Mongoose data saving without _id

Question

I am using mongoose with node.js application. I don't want _id field in record. I am using this code to save my record without _id field. But it is giving error document must have an _id before saving ``` var mongoose = require('mongoose'); var Schema = mongoose.Schema; var PlayerSchema = new Schema({ player_id : { type: Number }, player_name : { type: String }, player_age : { type: Number }, player_country : { type: String } } , { _id: false } ); var Player = mongoose.model('Player', PlayerSchema ); var athlete = new Player(); athlete.player_id = 1; athlete.player_name = "Vicks"; athlete.player_age = 20; athlete.player_country = "UK"; athlete.save(function(err) { if (err){ console.log("Error saving in PlayerSchema"+ err); } }); ``` I am using mongoose version 3.8.14

Accepted Answer

Unfortunately, You can not skip having a primary key for the document but you can override the primary key content, you can define your own primary key for each document.

Try the following schema for the same.

```
var PlayerSchema = new mongoose.Schema({
_id :  { type: Number },
player_name : { type: String },
player_age  : { type: Number },
player_country : { type: String },
```

} );

I have replaced your `player_id` with `_id`. Now you have control over the primary key of the document and the system won't generate the key for you.

There are some plugins which can also do the `autoincremet` for your primary key. https://github.com/chevex-archived/mongoose-auto-increment. You might try these as well.

Also, about the error you are getting : Any document is an object and should be wrapped inside the `curly brackets` you can not define two independent object in the same document. So you are getting this error.
