Question
I am trying to add a record into a database but its showing me a error: An exception of type 'System.Data.Entity.Infrastructure.DbUpdateException' occurred in EntityFramework.dll but was not handled in user code i get this error when i run my program, it does not even open my view in web-browser
This is my model:
public class MovieModel
{
public int ID { set; get; }
public string FirstName { set; get; }
public string SecondName { set; get; }
public DateTime DOB { set; get; }
public string Type{ set; get; }
}
This is my controller:
namespace Movie.Controllers
{
public class MoviesController : Controller
{
private ApplicationDbContext db = new ApplicationDbContext();
//
// GET: /Movies/
public ActionResult AddUsers(MovieModel model)
{
if (ModelState.IsValid)
{
db.Movies.Add(model);
db.SaveChanges();
}
return View(model);
}
}
}
Second Question when up-grading my database upgrade-database how do i specify a forgone key? is this have to be done via microsoft sql server management?
Accepted Answer
This occurs when you are trying to add/insert a record in an object other than a table. Is Movie a table or a view?
If it is a table, be sure your table has a primary key which doesn't allow duplication.
If not add the primary key and update the Entity Framework model and run again.
UPDATES : You can create an empty get action. To do so, update your controller as follows
//
// GET: /Movies/
public ActionResult AddStudent()
{
return View();
}
//
// POST: /Movies/
[Post]
public ActionResult AddStudent(MovieModel model)
{
if (ModelState.IsValid)
{
db.Movies.Add(model);
db.SaveChanges();
}
return View(model);
}
