Strongly typed views in NHaml?

Question

I have a strongly typed view and want to use it in an NHaml page.

With the WebForms engine I would describe the ViewData type in the <%@ Page%> directive or in the codebehind file.

How would I go about that in NHaml?

If I understand correctly you just want to have a strong typed nhaml view?

If this is the case there is a sample project in svn that does this. Have a look at

http://nhaml.googlecode.com/svn/trunk/src and the NHaml.Samples.Mvc.CSharp project

And here is some extracted code

Controller

public class ProductsController : Controller
{
    private readonly NorthwindDataContext northwind = new NorthwindDataContext(
        ConfigurationManager.ConnectionStrings["NorthwindConnectionString"].ConnectionString );


    public ActionResult Edit( int id )
    {
        var viewData = new ProductsEditViewData { Product = northwind.GetProductById( id ) };

        viewData.Categories = new SelectList( northwind.GetCategories(), "CategoryID", "CategoryName", viewData.Product.CategoryID );
        viewData.Suppliers = new SelectList( northwind.GetSuppliers(), "SupplierID", "CompanyName", viewData.Product.SupplierID );

        return View( "Edit", viewData );
    }

}

View

%h2= ViewData.Model.Product.ProductName
%form{action='#{Url.Action("Update", new { ID=ViewData.Model.Product.ProductID \})}' method="post"}
  %table
    %tr
      %td Name:
      %td= Html.TextBox("ProductName", ViewData.Model.Product.ProductName)
    %tr
      %td Category:
      %td= Html.DropDownList("CategoryID", ViewData.Model.Categories, (string)null)
    %tr
      %td Supplier:
      %td= Html.DropDownList("SupplierID", ViewData.Model.Suppliers, (string)null)
    %tr
      %td Unit Price:
      %td= Html.TextBox("UnitPrice", ViewData.Model.Product.UnitPrice.ToString())
  %p
  - Html.RenderPartial(@"_Button")

View Model

public class ProductsEditViewData
{
    public Product Product { get; set; }
    public SelectList Suppliers { get; set; }
    public SelectList Categories { get; set; }
}

Hope that helps
