Stop Mongoose from creating _id property for sub-document array items
It's simple, you can define this in the subschema :
var mongoose = require("mongoose");
var subSchema = mongoose.Schema({
// your subschema content
}, { _id : false });
var schema = mongoose.Schema({
// schema content
subSchemaCollection : [subSchema]
});
var model = mongoose.model('tablename', schema);
You can create sub-documents without schema and avoid _id
. Just add _id: false
to your subdocument declaration.
var schema = new mongoose.Schema({
field1: {
type: String
},
subdocArray: [{
_id: false,
field: { type: String }
}]
});
This will prevent the creation of an _id
field in your subdoc.
Tested in Mongoose v5.9.10
