Listing 9-5. Adding the Summary Method to the CartController.cs File
using System.Linq;
using System.Web.Mvc;
using SportsStore.Domain.Abstract;
using SportsStore.Domain.Entities;
using SportsStore.WebUI.Models;
namespace SportsStore.WebUI.Controllers {
public class CartController : Controller {
private IProductRepository repository;
public CartController(IProductRepository repo) {
repository = repo;
}
// . . . other action methods omitted for brevity . . .
}
}
public PartialViewResult Summary(Cart cart) {
return PartialView(cart);
}
This simple method needs to render a view, supplying the current Cart (which will be obtained using the custom model
binder) as view data. To create the view, right-click the Summary action method and select Add View from the pop-up
menu. Set the name of the view to Summary and click the OK button to create the Views/Cart/Summary.cshtml
file. Edit the view so that it matches Listing 9-6.
Listing 9-6. The Contents of the Summary.cshtml File
@model SportsStore.Domain.Entities.Cart
@Html.ActionLink("Checkout", "Index", "Cart",
new { returnUrl = Request.Url.PathAndQuery },
new { @class = "btn btn-default navbar-btn" })
Your cart:
@Model.Lines.Sum(x => x.Quantity) item(s),
@Model.ComputeTotalValue().ToString("c")
The view displays the number of items in the cart, the total cost of those items, and a link that shows the details of the cart to
the user (and, as you will have expected by now, I have assigned the elements that the view contains to classes defined by
Bootstrap). Now that I have created the view that is returned by the Summary action method, I can call the Summary action
method in the _Layout.cshtml file to display the cart summary, as shown in Listing 9-7.
