Question

In a ASP.NET MVC3 Razor project I have 2 Models

public class Post
    {
        public int Id { get; set; }
        public string Title { get; set; }
        public string Contents { get; set; }
        public int Author { get; set; }
    }

 public class Author
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Email { get; set; }
    }

Post.Author field links to Author.Id field

In a view, I need to display list of

Post.Title
Post.Contents
Author.Name

How to display the information joining (from) both models?

Note : I guess I need to use a ViewModel and bind the view with IEnumerable List, but I have no idea how to select the data from both models

Answer 1

You can create a viewmodel which will have ONLY properties which u want to be displayed on view

public class PostViewModel
{
        public int Id { get; set; }
        public string Title { get; set; }
        public string Contents { get; set; }
        public string AuthorName { get; set; }

}

You populate this viewmodel with your data in your controller action taking necessary joins

public ActionResult GetAuthorInfor()
{
   var query = //context.Post join with context.Author
               Select new  PostViewModel()
               {
                  Id = post.id,
                  Title = post.title,
                  Contents = post.contents,
                  AuthorName = author.authorname
               }
   return view(query.Single());
}

and create a typed view to render this model.
