MVC4 Ignoring [HttpGet] and [HttpPost] attributes

Question

I am attempting to make a simple test website to allow me to list, create, edit and delete customer objects using MVC4.

Inside my controller I have 2 create methods, a Get for when the form loads with the controls, and a Post that actually saves the data.

    //
    // GET: /Customer/Create

    [HttpGet]
    public ActionResult Create()
    {
        return View();
    }

    //
    // POST: /Customer/Create

    [HttpPost]
    public ActionResult Create(Customer cust)
    {
        if (ModelState.IsValid)
        {
            _repository.Add(cust);
            return RedirectToAction("GetAllCustomers");
        }

        return View(cust);
    }

However when I run the project and attempt to access the create action I get an error that:

The current request for action 'Create' on controller type 'CustomerController' is ambiguous between the following action methods:
System.Web.Mvc.ActionResult Create() on type [Project].Controllers.CustomerController
System.Web.Mvc.ActionResult Create([Project].Models.Customer) on type [Project].Controllers.CustomerController

My I understand that it can't see the difference between my Get and Post methods, but I have added the attribues. What could be the cause of this and how can I make it work again?

Answer 1

MVC does not authorize you to have 2 action methods with the same name.

BUT you can have 2 action methods with the same URI when the http verb differs (GET, POST). Use the ActionName attribute to set the action name. Don't use the same methods names. You can use any name. A convention is to add the http verb as the method suffix.

[HttpPost]
[ActionName("Create")]
public ActionResult CreatePost(Customer cust)
{
    if (ModelState.IsValid)
    {
        _repository.Add(cust);
        return RedirectToAction("GetAllCustomers");
    }

    return View(cust);
}
