«ApplicationDbContext» не содержит определения для «Items»

Question

У меня нет понятия, что я делаю неправильно, это просто обычный проект asp.net mvc5. это мой контроллер:

private ApplicationDbContext db = new ApplicationDbContext(); 

    // GET: Items 
    public ActionResult Index(string sortOrder, string currentFilter, string searchString, int? page) 
    { 
     ViewBag.CurrentSort = sortOrder; 
     ViewBag.NameSortParm = String.IsNullOrEmpty(sortOrder) ? "name_desc" : ""; 
     ViewBag.PriceSortParm = sortOrder == "Price" ? "price_desc" : "Price"; 

     if (searchString != null) 
     { 
      page = 1; 
     } 
     else 
     { 
      searchString = currentFilter; 
     } 

     ViewBag.CurrentFilter = searchString; 

     var items = from i in db.Items 
         select i; 
     if (!String.IsNullOrEmpty(searchString)) 
     { 
      items = items.Where(s => s.Name.ToUpper().Contains(searchString.ToUpper()) 
            || s.Catagorie.Name.ToUpper().Contains(searchString.ToUpper())); 
     } 
     switch (sortOrder) 
     { 
      case "name_desc": 
       items = items.OrderByDescending(s => s.Name); 
       break; 
      case "Price": 
       items = items.OrderBy(s => s.Price); 
       break; 
      case "price_desc": 
       items = items.OrderByDescending(s => s.Price); 
       break; 
      default: // Name ascending 
       items = items.OrderBy(s => s.Name); 
       break; 
     } 

     int pageSize = 3; 
     int pageNumber = (page ?? 1); 
     return System.Web.UI.WebControls.View(items.ToPagedList(pageNumber, pageSize)); 


     //var items = db.Items.Include(i => i.Catagorie); 
     //return View(await items.ToListAsync()); 
    } 

    // GET: Items/Details/5 
    public async Task<ActionResult> Details(int? id) 
    { 
     if (id == null) 
     { 
      return new HttpStatusCodeResult(HttpStatusCode.BadRequest); 
     } 
     Item item = await db.Items.FindAsync(id); 
     if (item == null) 
     { 
      return HttpNotFound(); 
     } 
     return View(item); 
    } 

    // GET: Items/Create 
    [Authorize(Roles = "Admin")] 
    public ActionResult Create() 
    { 
     ViewBag.CatagorieId = new SelectList(db.Catagories, "ID", "Name"); 
     return View(); 
    } 

    // POST: Items/Create 
    [HttpPost] 
    [ValidateAntiForgeryToken] 
    [Authorize(Roles = "Admin")] 
    public async Task<ActionResult> Create(Item item) 
    { 
     if (ModelState.IsValid) 
     { 
      db.Items.Add(item); 
      await db.SaveChangesAsync(); 
      return RedirectToAction("Index"); 
     } 

     ViewBag.CatagorieId = new SelectList(db.Catagories, "ID", "Name", item.CatagorieId); 
     return View(item); 
    } 

    // GET: Items/Edit/5 
    [Authorize(Roles = "Admin")] 
    public async Task<ActionResult> Edit(int? id) 
    { 
     if (id == null) 
     { 
      return new HttpStatusCodeResult(HttpStatusCode.BadRequest); 
     } 
     Item item = await db.Items.FindAsync(id); 
     if (item == null) 
     { 
      return HttpNotFound(); 
     } 
     ViewBag.CatagorieId = new SelectList(db.Catagories, "ID", "Name", item.CatagorieId); 
     return View(item); 
    } 

    // POST: Items/Edit/5 
    [HttpPost] 
    [ValidateAntiForgeryToken] 
    [Authorize(Roles = "Admin")] 
    public async Task<ActionResult> Edit(Item item) 
    { 
     if (ModelState.IsValid) 
     { 
      db.Entry(item).State = EntityState.Modified; 
      await db.SaveChangesAsync(); 
      return RedirectToAction("Index"); 
     } 
     ViewBag.CatagorieId = new SelectList(db.Catagories, "ID", "Name", item.CatagorieId); 
     return View(item); 
    } 

    // GET: Items/Delete/5 
    [Authorize(Roles = "Admin")] 
    public async Task<ActionResult> Delete(int? id) 
    { 
     if (id == null) 
     { 
      return new HttpStatusCodeResult(HttpStatusCode.BadRequest); 
     } 
     Item item = await db.Items.FindAsync(id); 
     if (item == null) 
     { 
      return HttpNotFound(); 
     } 
     return View(item); 
    } 

    // POST: Items/Delete/5 
    [HttpPost, ActionName("Delete")] 
    [ValidateAntiForgeryToken] 
    [Authorize(Roles = "Admin")] 
    public async Task<ActionResult> DeleteConfirmed(int id) 
    { 
     Item item = await db.Items.FindAsync(id); 
     db.Items.Remove(item); 
     await db.SaveChangesAsync(); 
     return RedirectToAction("Index"); 
    } 

    public async Task<ActionResult> RenderImage(int id) 
    { 
     Item item = await db.Items.FindAsync(id); 

     byte[] photoBack = item.InternalImage; 

     return File(photoBack, "image/png"); 
    } 

    protected override void Dispose(bool disposing) 
    { 
     if (disposing) 
     { 
      db.Dispose(); 
     } 
     base.Dispose(disposing); 
    } 

И я получаю следующую ошибку Severity Code Description Project File Line Error CS1061 'ApplicationDbContext' does not contain a definition for 'Items' and no extension method 'Items' accepting a first argument of type 'ApplicationDbContext' could be found (are you missing a using directive or an assembly reference?)

Но на моей базе данных у меня есть таблица Items и я, указывая на нужную базу.

Answer 1

Вы должны иметь что-то вроде этого:

public class ApplicationDbContext : DbContext 
{ 
    public DbSet<Item> Items { get; set; } 
    // Rest of data models 
} 

Если нет, то это не является не идти.
