    <p>I'm trying to use ViewModels for the first time using AutoMapper. I have two models:</p> <pre><code>public class Item { public int ItemId { get; set; } public bool Active { get; set; } public string ItemCode { get; set; } public string Name { get; set; } public List&lt;ItemOption&gt; ItemOptions { get; set; } //... } public class ItemOption { public int ItemOptionId { get; set; } public string Name { get; set; } public string Barcode { get; set; } //... } </code></pre> <p>Which I have turned into two ViewModels:</p> <pre><code>public class ItemDetailViewModel { public int ItemDetailViewModelId { get; set; } public int ItemId { get; set; } public bool Active { get; set; } public string ItemCode { get; set; } public string Name { get; set; } public List&lt;ItemDetailItemOptionViewModel&gt; ItemOptions { get; set; } } public class ItemDetailItemOptionViewModel { public int ItemDetailItemOptionViewModelId { get; set; } public int ItemOptionId { get; set; } public string Name { get; set; } public string Barcode { get; set; } } </code></pre> <p>I then set the following in my application start-up:</p> <pre><code>Mapper.CreateMap&lt;Item, ItemDetailViewModel&gt;(); Mapper.CreateMap&lt;ItemOption, ItemDetailItemOptionViewModel&gt;(); </code></pre> <p>Finally I scaffolded my ItemDetailViewModel:</p> <p><img src="https://i.stack.imgur.com/IdASh.png" alt="enter image description here"></p> <p>I then built my project and added a new Item through /Item/Create</p> <p>I had a look in the database expecting to see that I would have an entry in the Item table, but instead I have ItemDetailViewModel and ItemDetailItemOptionViewModel tables, which I wasn't expecting and the data is is ItemDetailViewModel.</p> <p>I assume I have done something wrong with my scaffolding? How do I scaffold off the ViewModel without making it part of the main business models?</p> <p><strong>Further Details</strong></p> <p>If it isn't possible to scaffold the controller with a ViewModel, then how do I reference the ViewModel in the controller and save changes back to the database?</p> <p>For example what would the following change to once I remove ItemDetailViewModel from the db context?</p> <pre><code> // // POST: /Item/Create [HttpPost] [ValidateAntiForgeryToken] public ActionResult Create(ItemDetailViewModel itemdetailviewmodel) { if (ModelState.IsValid) { db.ItemDetailViewModels.Add(itemdetailviewmodel); db.SaveChanges(); return RedirectToAction("Index"); } return View(itemdetailviewmodel); } </code></pre> <p><strong>Further Details [2]</strong></p> <p>So am I correct that my Index/Details should work as so or is there a better way of doing it?</p> <pre><code> // // GET: /Item/ public ActionResult Index() { var items = db.Items.ToList(); var itemdetailviewmodel = AutoMapper.Mapper.Map&lt;ItemDetailViewModel&gt;(items); return View(itemdetailviewmodel); } // // GET: /Item/Details/5 public ActionResult Details(int id = 0) { ItemDetailViewModel itemdetailviewmodel = AutoMapper.Mapper.Map&lt;ItemDetailViewModel&gt;(db.Items.Find(id)); if (itemdetailviewmodel == null) { return HttpNotFound(); } return View(itemdetailviewmodel); } </code></pre>

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.
