I have a college project in which I decided to do a blog . Something very simple, author, post and comments. only these three. Well
First I wanted the home of the project to load the Blog Posts . I got it. Now I want below each post to give a count in the comments. How can I do this?
Class Codes:
public class Post
{
public Post()
{
}
[Required]
public int PostId { get; set; }
[Required]
public int AutorId { get; set; }
[Required]
public string Titulo { get; set; }
[Required]
public string Conteudo { get; set; }
public virtual Autor Autor { get; set; }
public virtual ICollection<Comentario> Comentarios { get; set; }
}
Controller
public class HomeController : Controller
{
private DbContexto db = new DbContexto();
public ActionResult Login()
{
return View(new LoginModel());
}
[HttpPost]
public ActionResult Login(LoginModel model)
{
//TODO efetuar o login
return RedirectToAction("Index");
}
public ActionResult Index()
{
var query = from e in db.Posts
select e;
var post = query.ToList();
return View(post);
}
public ActionResult About()
{
ViewBag.Message = "Your application description page.";
return View();
}
public ActionResult Contact()
{
ViewBag.Message = "Your contact page.";
return View();
}
}
Model
@model IEnumerable<WebBlog.Models.Post>
@{
ViewBag.Title = "Home Page";
}
<style type="text/css">
