Can a subdocument be required in mongoose?

Is it possible to have nested schemas in mongoose and have a required validator on the children? Something like this:

const userSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  }
});

const eventSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  },
  host: {
    type: userSchema,
    required: true
  }
});

I can't find anything in the documentation. Thanks.

required is a validator added to a schema or subschema in Mongoose (from docs) so yes, you can set the required field to true ( it is false by default) for your subschema or subdocument in Mongoose. The example schema you have created is correct.

i suppose you'll update eventSchema with subdocuments of type user model. you can use { runValidators: true} for update.

eventModel.update({ name: 'YOUR NAME' }, { $push: { host: user } }, { runValidators: true}, function(err) {

})

You can use the nested schema in mongoose.

It will also give you he Object Id on each sub schema values as well.

Yes, your schema is correct.

The docs for mongoose nested schema (SubDocuments) can be found here
