Passing object from View to Controller ASP.NET MVC - asp.net-mvc

Question

so my intention is to make a button that allow a user to add an item to his Cart, in the db.savechanges method it catch these exceptions :
Property: Item_Name Error: The Item_Name field is required.
iisexpress.exe Information: 0 : Property: Item_Description Error:
The Item_Description field is required. s
i checked from my db and every single item has all their properties filled up, since i am new to asp.net i am surely missing something obvious that is messing with my data.
this is the view(trying to pass the item object in actionlink
#foreach (var item in Model)
{
if (index > 6)
{
index = 0;
}
var newrow = 0;
if (index == 0)
{
newrow = 1;
}
if (newrow == 1)
{
index++;
<div class="product-one">
<div class="col-md-2 product-left">
<div class="p-one simpleCart_shelfItem jwe">
<a href="single.html">
<!-- go to product single view page-->
#{ if (item.Image.Image1 != null)
{
string imageBase64 = Convert.ToBase64String(item.Image.Image1);
string imageSrc = string.Format("data:image/png;base64,{0}", imageBase64);
<img src="#imageSrc" width="100" height="100" />
}
}
#Html.ActionLink("Add to Cart", "AddToCart", "Carts", new { itemdata = item }, new { #class = "btn btn-primary btn-large" })
</a>
<br />
</div>
</div>
</div>
this is the controller:
public ActionResult AddToCart(Item item)
{
//var query = from itemsel in db.Items where item.Item_ID == item.Item_ID select item;
var newcart = new Cart();
newcart.Account_ID = 1;
newcart.Cart_ID = 3;
newcart.Item_ID = item.Item_ID;
newcart.Item = item;
var itemsgroup = db.Items;
try
{
db.Carts.Add(newcart);
db.SaveChanges();
}
catch (DbEntityValidationException dbEx)
{
foreach (var validationErrors in dbEx.EntityValidationErrors)
{
foreach (var validationError in validationErrors.ValidationErrors)
{
Trace.TraceInformation("Property: {0} Error: {1}",
validationError.PropertyName,
validationError.ErrorMessage);
}
}
}
return View(itemsgroup.ToList());
}
and this is the cart model:
public partial class Cart
{
public int Cart_ID { get; set; }
public int Account_ID { get; set; }
public int Item_ID { get; set; }
public virtual Item Item { get; set; }
}
}
p.s i know my view is tricky but i am desperate to finish this project very soon, any suggestion for a better way of doing it would be welcomed

Since you are missing too many pieces, I could only point you to right direction.
Download the sample source code of Pro ASP.NET MVC 5 book By Adam Freeman.
Extract Chapter 9 - SportsStore, and look at those two files-
SportsStore.WebUI > Views > Product > List.cshtml
#foreach (var p in Model.Products) {
#Html.Partial("ProductSummary", p)
}
SportsStore.WebUI > Views > Shared > ProductSummary.cshtml
Notice that it uses BeginForm to add individual item to shopping cart.
#using (Html.BeginForm("AddToCart", "Cart")) {
<div class="pull-right">
#Html.HiddenFor(x => x.ProductID)
#Html.Hidden("returnUrl", Request.Url.PathAndQuery)
<input type="submit" class="btn btn-success" value="Add to cart" />
</div>
}
