MongoDB best practice for referencing

Question

I\'m wondering what the best practice for modelling by using references would be given situation under. I\'m using MongoRepository library.

public class User         


        

Answer 1

You can use MongoDBRef object instead of User object.

public class Post : Entity
{
    public string Id { get; set; }
    public string Title { get; set; }
    public string Summary { get; set; }
    public DateTime Added { get; set; }
    public MongoDBRef Owner { get; set; }
}    

Then you can:

var mongo = new Mongo(config.BuildConfiguration());
mongo.Connect();        
var DB = mongo.GetDatabase(_dataBaseName)

var post = new Post();
post.Owner = new MongoDBRef("User", userId); // First parameter is a mongoDB collection name and second is object id
// To fetch object referenced by DBRef you should do following
var owner = DB.FollowReference(post.Owner);
