SubSonic Simple Repository One-To-Many - subsonic

Question

I made a class like:
public class Video
{
public Guid VideoID { get; set; }
public VideoCategory VideoCategory { get; set; }
public int SortIndex { get; set; }
public string Title { get; set; }
public string Body { get; set; }
public string Author { get; set; }
public string Filename { get; set; }
public new void Add()
{
this.VideoID = Guid.NewGuid();
DB.Repository.Add(this);
}
}
And another like
public class VideoCategory
{
public Guid VideoCategoryID { get; set; }
public string Title { get; set; }
public new void Add()
{
this.VideoCategoryID = Guid.NewGuid();
DB.Repository.Add(this);
}
}
I then have code like:
VideoCategory VideoCategory = new VideoCategory();
VideoCategory.Title = "TestTitle";
VideoCategory.Add();
Video Video = new Video();
Video.VideoCategory = VideoCategory;
Video.SortIndex = 1;
Video.Title = "TestTitle";
Video.Body = "TestBody";
Video.Author = "TestAuthor";
Video.Filename = "TestFile.flv";
Video.Add();
It doesn't save the VideoCategory into my database, so obviously i'm missing something. What else is needed to done to save a one-to-many relationship?

Answer 1

You could probably just do the following, you'll probably want to tidy it up but it will ensure your foreign key value gets populated:
public class Video
{
protected VideoCategory videoCategory;
public Guid ID { get; set; }
public VideoCategory VideoCategory
{
get { return videoCategory; }
set
{
videoCategory = value;
VideoCategoryId = value.ID;
}
}
public Guid VideoCategoryId { get; set; }
public int SortIndex { get; set; }
public string Title { get; set; }
public string Body { get; set; }
public string Author { get; set; }
public string Filename { get; set; }
}
public class VideoCategory
{
public Guid ID { get; set; }
public string Title { get; set; }
}
SimpleRepository repo = new SimpleRepository(SimpleRepositoryOptions.RunMigrations);
VideoCategory videoCategory = new VideoCategory();
videoCategory.ID = Guid.NewGuid();
videoCategory.Title = "TestTitle";
repo.Add<VideoCategory>(videoCategory);
Video video = new Video();
video.ID = Guid.NewGuid();
video.VideoCategory = videoCategory;
video.SortIndex = 1;
video.Title = "TestTitle";
video.Body = "TestBody";
video.Author = "TestAuthor";
video.Filename = "TestFile.flv";
repo.Add<Video>(video);

Answer 2

You're not missing anything. Simplerepository doesn't support one to many out of the box.

Answer 3

Heres a useful link that shows how to mangage foreign keys yourself in SimpleRepository -
subsonic-3-simplerepository
Have not tried it myself, but looks like it would actually work.
Fluent Nhibernate will do this foriegn key management for you automatically, but it's a LOT more complex.
