Optional nested schema

[sidvorak]

I'm having an issue when attempting to use a nested schema. For instance:

const Camera = new Schema({
    model: {
        type: string,
        required: true,
    }
};

const Room = new Schema({
    name: {
        type: string,
        required: true,
    }
    camera: {
        type: Camera,
        required: false
    }
};

const roomObj = {
    name: "My room",
    camera: {
        model: "abc123"
    }
};

const errors = Room.validate(roomObj);
// ValidationError: camera must be of type [object Object].

If I define the room schema like:

const Room = new Schema({
    name: {
        type: string,
        required: true,
    }
    camera: Camera
};

const roomObj = {
    name: "My room",
    camera: {
        model: "abc123"
    }
};

It works as long as I pass the nested camera object with the required properties, but I get validation errors if the nested camera object is not including in the room object.

Is there a way to have an optional nested schema?
