MVC form post Question

I'm newbie to MVC and my FORM Post is not working. Could anyone tell me if I pass Dinner object to the VIEW. And do HTTP POST, should MVC give Person object back? e.g. public ActionResult Edit(int id) {

        Dinner dinner = dinnerRepository.GetDinner(id);

        if (!dinner.IsHostedBy(User.Identity.Name))
            return View("InvalidOwner");

        return View(dinner);
    }

public Ac开发者_如何学JAVAtionResult Edit(Dinner dinner) {

        //should this dinner class be populated?

    }

The default model binder automatically populates action arguments if values are present in the request. So for example if your form contains the following fields:

<input type="text" name="Foo" />
<input type="text" name="Bar" />

and your Dinner object contains those properties:

public class Dinner
{
    public string Foo { get; set; }
    public string Bar { get; set; }
}

then when you submit the form to the following action:

[HttpPost]
public ActionResult Edit(Dinner dinner)
{
    // the dinner.Foo and dinner.Bar properties will be
    // automatically bound from the request
    ...
}
