    <p>using C#, VS2012, MVC4, CodeFirst</p> <p>I've read tons of posts here and elsewhere about one to many with a viewmodel but I can't quite get it.</p> <p>I have a program, AddressBook, with two tables, Name and Phone. For each name, you can have many numbers. Models below:</p> <pre><code>namespace AddressBook.Models { public class Name { public int NameID { get; set; } public string FirstName { get; set; } public string LastName { get; set; } //ref public ICollection&lt;Phone&gt; Phones { get; set; } } } namespace AddressBook.Models { public class Phone { public int ID { get; set; } public string Number { get; set; } //ref [Required] public int NameId { get; set; } public Name Name { get; set; } } } </code></pre> <p>and my context:</p> <pre><code>public class ContactDBContext : DbContext { public DbSet&lt;Name&gt; Names { get; set; } public DbSet&lt;Phone&gt; Phones { get; set; } } </code></pre> <p>My DetailViewModel:</p> <pre><code>public class DetailViewModel { public Name ID { get; set; } public Name FirstName { get; set; } public Name LastName { get; set; } public List&lt;Phone&gt; Number { get; set; } } </code></pre> <p>Now my controller, I start to get stuck. I'm able to call the list of Phone, but I seem can't get the isolated Name record.</p> <pre><code>public ActionResult Details(int id = 0) { DetailViewModel dvm = new DetailViewModel(); dvm.FirstName = (from n in db.Names select n).Where(m =&gt; m.NameID == id).ToString(); dvm.LastName = (from n in db.Names where n.NameID == id select n).ToString(); dvm.Number = (from n in db.Phones select n).Where(m =&gt; m.NameId == id).ToList(); //tried a couple of different things return View(dvm); //Name name = db.Names.Find(id); //if (name == null) //{ // return HttpNotFound(); //} //return View(name); } </code></pre> <p>User should be able to perform CRUD on Phone table once in the Details view for selected Name record. Phone CRUD can be completed on same or different page, whichever is easier to code.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
