Can a Developer help me with this?

I need to List, Create, and Edit products in the main website itself : Nop.Web (not Nop.Admin).

I used List, Create, and Edit Scaffolding Views with the Product model "@model Nop.Core.Domain.Catalog.Product"
List and Create both work.

But having trouble with Edit. The Edit screen displays the form with the fields I have chosen.
But when I click "Save" it doesn't update any of the fields:

        public ActionResult Edit(int id)
        {
            var product = _productService.GetProductById(id);
            return View(product);
        }

        [HttpPost]
        public ActionResult Edit(Product model) 
        {
            model.AdminComment = "test";       
            _productService.UpdateProduct(model);   // doesn't work

            return RedirectToAction("Index");
        }
View:
@model Nop.Core.Domain.Catalog.Product
@using (Html.BeginForm())
{
        @Html.HiddenFor(model => model.Id)

        <div class="form-group">
            @Html.LabelFor(model => model.Name, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Name)
                @Html.ValidationMessageFor(model => model.Name)
             .............

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Save" class="btn btn-default" />
         ........
}

I also tried : _productRepository.Update(model); but that didn't work either.

The "_productService.InsertProduct(model)" works but "_productService.UpdateProduct(model)" doesn't.

In the Nop.Admin Edit code, it looks like this :  public ActionResult Edit(ProductModel model, bool continueEditing)  { . .
But the ProductModel is in the Admin project and I can't access it.
But the Create works with just the Product model.

Can anyone see why the Edit is not updating?
Thanks

Set breakpoint into your [HttpPost] public ActionResult Edit(Product model) method.
When you hit the breakpoint, do you see filled model?
Do you see any errors in log?

Are you using Ajax?  Check that no client side errors are being thrown. (Turn on browser developer tools)

Yes, the Product gets populated, it just doesn't update. Nothing in the logs.

Not sure how to use that tool or even what to look for at this point.

But I did get it working. It seems the _productService.UpdateProduct(product) wants a ProductModel view model to work.
The only access to that model is in the Nop.Admin project.

So what I did, which is kind of crazy, is create a Controller in the Admin project, have it update the ProductModel,
and return back to the Controller in Nop.Web. Looks something like this :

namespace Nop.Admin.Controllers
{
    public class GiftListEditController : Controller
    {
        private readonly IProductService _productService;
        public GiftListEditController(IProductService _productService)  {
             this._productService = _productService;      }


 public ActionResult Edit(int id)  // created using Edit scaffold
        {
            var product = _productService.GetProductById(id);
            var model = product.ToModel();
            return View(model);
        }

        [HttpPost] 
        public ActionResult Edit(ProductModel model)
        {
            var product = _productService.GetProductById(model.Id);
            if (ModelState.IsValid)
            {
                product = model.ToEntity(product);
                product.UpdatedOnUtc = DateTime.UtcNow;
                _productService.UpdateProduct(product);
            }
            return RedirectToAction("Index", "GiftList", new { area = "" }); // returns to Nop.Web 
        }
VIEW :
@model Nop.Admin.Models.Catalog.ProductModel

@{ 
   Layout = "~/Nop.Web/Views/Shared/_ColumnsOne.cshtml";  } << this actually worked; getting a View from Nop.Web

@using (Html.BeginForm("Edit", "GiftListEdit"))
..........
@Html.ActionLink("Back to List", "Index", "GiftList", new { area = "" }, null)  << returns to Nop.Web


For the Edit link to go to the Nop.Admin Controller :

@Html.ActionLink("Edit", "Edit", "GiftListEdit", new { id = item.Id }, new { Area = "Admin" } )  

This is crazy but it works.

Was playing around and it turns out I don't need the crazy Nop.Admin controller code (above).

Got this to work by mapping the fields of the model to the retrieved product :

        [HttpPost]
        public ActionResult Edit(Product model)
        { 
            var product = _productService.GetProductById(model.Id);
            // map each property in product to form fields in the Product model parameter :
            product.AdminComment = model.AdminComment;
            product.ShortDescription = model.ShortDescription;
            product.Name = model.Name;
            ...............
            _productService.UpdateProduct(product);
            ........
