How can I set the field to JSON in MongooseJS?

My Mongoose model is:

var Schema = new Schema({
  code: String,
  type: String,
  people:{}
}

and data for items is :

people :  
    {
        "id":"2342423",
        "name":"John"
    },
    {
        "id":"1231231",
        "name":"Marry"
    }

when I write:

    var obj = new Schema({
            people:people});

obj.people is {}. Where am I wrong?

people should be of type Object or Array

What you have isn't valid JSON. The top level needs to be a single object or array, so you might want something like the following:

people: [
    {
        "id":"2342423",
         "name":"John"
    },
    {
        "id":"1231231",
        "name":"Marry"
    }
]

That's a single array, containing objects that have information about two people.
