在一個視圖中通過多個模型創建新記錄

-2

我遇到了無法將記錄保存到數據庫中的問題。我在一個視圖中有3個模型。我做了這個在一個視圖中通過多個模型創建新記錄

型「System.Data.Entity.Validation.DbEntityValidationException」發生在EntityFramework.dll的例外視圖，並得到錯誤，但在用戶代碼

其他信息沒有處理：一個或多個實體的驗證失敗。有關更多詳細信息，請參閱「EntityValidationErrors」屬性。

這裏是我的看法

這裏是我的控制器

    { 
     ViewBag.CompanyID = new SelectList(db.SupplierTables, "SupplierID", "SupplierID"); 
     ViewBag.Product = new SelectList(db.ProductTables, "ProductID", "ProductID"); 
     ViewBag.Category = new SelectList(db.CategoryTables, "CategoryID", "CategoryID"); 
     ViewBag.PaymentTerm = new SelectList(db.PaymentTerms, "TermID", "TermID"); 
     return View(); 
    } 

    [HttpPost] 
    public ActionResult Create([Bind(Include = "PurchaseInvoiceTable,PurchaseInvoiceDetailsTable,PaymentTerm")]InvoiceWrapper model)    
    { 
     if (ModelState.IsValid) 
     { 

       db.PurchaseInvoiceTables.Add(model.PurchaseInvoiceTable); 
       db.PurchaseInvoiceDetailsTables.Add(model.PurchaseInvoiceDetailsTable); 
       db.PaymentTerms.Add(model.PaymentTerm); 
       db.SaveChanges(); 

      //model.PurchaseInvoiceTable.PurchaseInvoiceID = model.PurchaseInvoiceDetailsTable.InvoiceID = model.PaymentTerm.InvoiceID;     

      return RedirectToAction("Index"); 
     } 

     ViewBag.CompanyID = new SelectList(db.SupplierTables, "SupplierID", "SupplierID"); 
     ViewBag.Product = new SelectList(db.ProductTables, "ProductID", "ProductID"); 
     ViewBag.Category = new SelectList(db.CategoryTables, "CategoryID", "CategoryID"); 
     ViewBag.PaymentTerm = new SelectList(db.PaymentTerms, "TermID", "TermID"); 
     return View(model); 


    }

你爲什麼要叫'db.PurchaseInvoiceDetailsTables.Add（model.PurchaseInvoiceDetailsTable）;'和'db.PaymentTerms。添加（model.PaymentTerm）;'兩次。什麼_See'EntityValidationErrors'屬性的更多細節_告訴你 –

爲什麼在世界上你有所有這些隱藏的輸入。使用視圖模型。 –

兩次是我做測試沒有刪除==，隱藏的輸入是當我創建它時會自動插入不會讓用戶鍵入隱藏的值 – nonstop328

您得到的手段，不同的是一個或多個，你要保存的實體性質的不有效。例如該列被定義爲非空，並且您嘗試保存的屬性爲空。

爲了看你可以用這個驗證錯誤：

catch (DbEntityValidationException dbEx) 
{ 
    foreach (var validationErrors in dbEx.EntityValidationErrors) 
    { 
     foreach (var validationError in validationErrors.ValidationErrors) 
     { 
      Trace.TraceInformation("Property: {0} Error: {1}", 
            validationError.PropertyName, 
            validationError.ErrorMessage); 
     } 
    } 
}
