I am trying to edit a record. I have the default route.
When I click the submit button I get an exception on the UpdateModel line:
The model of type 'MyProject.Mvc.Models.Product' could not be updated.
On the page the validation of the ProductId field is prompting the value is invalid:
The value '9' is invalid. 9 is the id of the record I am trying to edit. What could be wrong?
public ActionResult Edit(int id)
{
Product product = productRepository.GetProduct(id);
return View(new ProductFormViewModel(product));
}
[HttpPost]
public ActionResult Edit(int id, FormCollection productFormViewModel)
{
Product product = productRepository.GetProduct(id);
try
{
// TODO: Add update logic here
UpdateModel(product, "Product");
productRepository.Save();
return RedirectToAction("Index");
}
catch (Exception ex)
{
return View(new ProductFormViewModel(product));
}
}
If I change the update model line to:
UpdateModel(product);
then no exception is thrown and the data is not updated in the database.
[Edit]
I am using Entity Framework
namespace MyProject.Mvc.Models
{
[MetadataType(typeof(ProductMetaData))]
public partial class Product
{
public Product()
{
// Initialize Product
this.CreateDate = System.DateTime.Now;
}
}
public class ProductMetaData
{
[Required(ErrorMessage = "Product name is required")]
[StringLength(50, ErrorMessage = "Product name must be under 50 characters")]
public object ProductName { get; set; }
[Required(ErrorMessage = "Description is required")]
public object Description { get; set; }
}
public class ProductFormViewModel
{
public Product Product { get; private set; }
public ProductFormViewModel()
{
Product = new Product();
}
public ProductFormViewModel(Product product)
{
Product = product;
}
}
}
