Cześć,
szukałem wszędzie odpowiedzi na mój problem i próbowałem wielu rzeczy. Może uda mi się znaleźć tutaj rozwiązanie.
Na swojej stronie próbuję zrobić możliwość rejestracji. Po wpisaniu danych, od razu pojawia się błąd:
System.Data.Entity.Validation.DbEntityValidationException: „Validation failed for one or more entities. See 'EntityValidationErrors' property for more details.”
Model, na którym buduję te rejestracje wygląda tak:
namespace GamissimaEdu.Models
{
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
public partial class Students
{
public int id { get; set; }
[Required]
[Column(TypeName = "varchar(64)")]
public string first_name { get; set; }
[Required]
[Column(TypeName = "varchar(64)")]
public string last_name { get; set; }
[Required]
[Column(TypeName = "varchar(255)")]
public string user_name { get; set; }
[Required]
[Column(TypeName = "varchar(255)")]
public string password { get; set; }
[Required]
[Column(TypeName = "varchar(MAX)")]
public string location { get; set; }
[Required]
[Column(TypeName = "varchar(80)")]
public string email { get; set; }
}
}
Kontroler:
using GamissimaEdu.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace GamissimaEdu.Controllers
{
public class HomeController : Controller
{
public ActionResult Index()
{
GamissimaDBEntities db = new GamissimaDBEntities();
var student = db.Students;
return View(student);
}
public ActionResult Login()
{
return View();
}
[HttpGet]
public ActionResult Register()
{
return View();
}
[HttpPost]
public ActionResult Register(Students obj)
{
GamissimaDBEntities db = new GamissimaDBEntities();
db.Students.Add(obj);
db.SaveChanges();
return View(obj);
}
}
}

Kiedy uruchamiam aplikację, ładuje się normalnie. Potem gdy klikam "submit", VStudio zatrzymuje się na linijce "db.Savechanges()" mówiąc, że nie obsługuje pewnego wyjątku. Wyświetlam szczegóły i zwróciłem uwagę, że parametr "IsValid" jest false. Nie wiem w którym miejscu mogłem popełnić błąd, szukam go. Próbowałem linijkę z db.SaveChanges wziąć w try catch, nic konkretnego nie znalazłem. Tak wygląda błąd po "kontynuacji".
Błąd serwera w aplikacji '/'.
