I try to reinterpretate [this simple tutorial][1]
In Book model I remove ScaffoldColumn(false) above public int AuthorID to have select AuthorID in my view.
After rebiuld I can see this select in Books/Create but it has no options.
In my database I can see, that all my items added in SampleData model has BookID and AuthorID.
Why it has no result in html ?
Edited:
My Book.cs
using System.ComponentModel.DataAnnotations;
namespace ContosoBooks.Models
{
public class Book
{
public int BookID { get; set; }
[Required]
public string Title { get; set; }
public int Year { get; set; }
[Range(1, 500)]
public decimal Price { get; set; }
public string Genre { get; set; }
public int AuthorID { get; set; }
// Navigation property
public virtual Author Author { get; set; }
}
}
My Author.cs
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
namespace ContosoBooks.Models
{
public class Author
{
public int AuthorID { get; set; }
[Required]
[Display(Name = "Last Name")]
public string LastName { get; set; }
[Display(Name = "First Name")]
public string FirstMidName { get; set; }
public virtual ICollection<Book> Books { get; set; }
}
}
My Scaffolded generated View for Books Create (Create.cshtml)
@model ContosoBooks.Models.Book
@{
ViewData["Title"] = "Create";
}
