Sure thing :)
I have removed a few things but the essential things should be there
public abstract class BaseEntity<T> : ActiveRecordValidationBase<T>
where T : class
{
private readonly DateTime created;
private DateTime modified;
public BaseEntity()
{
created = DateTime.Now;
modified = DateTime.Now;
}
[Property("Created", Access = PropertyAccess.NosetterLowercase,
NotNull = true)]
public DateTime? Created
{
get { return created; }
}
[Property("Modified", Access = PropertyAccess.NosetterLowercase,
NotNull = true)]
public DateTime Modified
{
get { return modified; }
}
public override void Update()
{
modified = DateTime.Now;
base.Update();
}
public override void UpdateAndFlush()
{
modified = DateTime.Now;
base.UpdateAndFlush();
}
public override void Save()
{
modified = DateTime.Now;
base.Save();
}
public override void SaveAndFlush()
{
modified = DateTime.Now;
base.SaveAndFlush();
}
protected override void OnSave()
{
modified = DateTime.Now;
base.OnSave();
}
protected override void OnUpdate()
{
modified = DateTime.Now;
base.OnUpdate();
}
}
public class Blog : BaseEntity<Blog>
{
[PrimaryKey(PrimaryKeyType.GuidComb, "Id", Access =
PropertyAccess.NosetterLowercase)]
public Guid Id
{
get { return id; }
}
[Property("Name", NotNull = true, Length = 255), ValidateNonEmpty
("Name is a required field")]
public string Name
{
get { return name; }
set { name = value; }
}
[HasMany(typeof(Post),
Table = "Posts",
ColumnKey = "BlogId",
Access = PropertyAccess.NosetterCamelcase,
RelationType = RelationType.Bag,

Inverse = true
)]
private IList<ProductVariantValue> Posts
{
get { return posts; }
}
public List<Post> PostList
{
get { return new List<Post>(Posts).AsReadOnly(); }
}
public void AddPost(Post post)
{
posts.Add(post);
}
public void RemovePost(Post post)
{
posts.Remove(post);
}
}
public class Post : BaseEntity<Post>
{
public Post(string value)
{
this.text = value;
}
[PrimaryKey(PrimaryKeyType.GuidComb, "Id", Access =
PropertyAccess.NosetterLowercase)]
public Guid Id

}

}

required field")]
public string Text

}
}
