ASP.NET MVC 2 Create a Model Using POST

Question

I have the following model:

public class Product {
 public int Id { get; set; }
 public string Name { get; set; }
 private int CategoryId { get; set; }
 public Category Category { get; set; }
 public string InventoryDetails { get; set; }
}

I have an action in my controller that is used to create a new product. My question is how to limit the properties of my model that may be associated with POST data? Because I want only the name and CategoryId to be connected by POST user data. Or is it better to create a separate view model that can only link these properties?

public ActionResult Create(Product p)

or

public ActionResult Create(CreateProductViewModel model)

Where

public class CreateProductViewModel {
 public string Name {get; set;}
 public int CategoryId {get;set;}
}

}

Note. If your view data format is almost equal to the data model, creating a separate view model is not good practice. Create a separate view model only if there are two different objects.
