Specifying Relationships in Models in ASP.NET MVC4 - asp.net-mvc

Question

I'm an ASP.NET MVC4 beginner and I'm trying to create a blog kind of. I have a problem with creating relationships in my models. Background of my issue is that, I have a model (Users.cs) with user information, a model (Posts.cs) containing posts information, and a third model (Comments.cs) containing comments information.
So a user can have many posts but a post can belong to only one user,
a user can have many comments but a comment can belong to only a user,
a post can have many comments but a comment can only belong to a post,
My question is, how do I write the three models? So far I have this:
public class Users
{
public int UserID { get; set; }
public string Firstname { get; set; }
public string Lastname { get; set; }
public DateTime DOB { get; set; }
public string Sex { get; set; }
public string Email { get; set; }
public DateTime RegDate { get; set; }
public string Username { get; set; }
public string Password { get; set; }
public string PasswordSalt { get; set; }
public virtual List<Posts> Post { get; set; }
public virtual List<Comments> Comment { get; set; }
}
class Posts
{
public int PostID { get; set; }
public string PostTitle { get; set; }
public string PostContent { get; set; }
public DateTime PostDate { get; set; }
public int AuthorID { get; set; }
public int CommentID { get; set; }
public virtual List<Comments> Comment { get; set; }
public virtual Users user { get; set; }
}
public class Comments
{
public int CommentID { get; set; }
public string Comment { get; set; }
public DateTime CommentDate { get; set; }
public int AuthorID { get; set; }
public int PostID { get; set; }
public virtual Posts post { get; set; }
public virtual Users user { get; set; }
}
Please how do I write the three models correctly? Help!!!

Answer 1

You have strongly typed model classes, and you're already using them correctly. You just need to remove the redundant properties pointing to ID's - Comments doesn't need an int AuthorID pointing to the author when it already has Users user.
Remove these properties:
class Posts
{
public int AuthorID { get; set; }
public int CommentID { get; set; }
}
public class Comments
{
public int AuthorID { get; set; }
public int PostID { get; set; }
}
