ASP.NET Core 2.1 Razor Form, Post not reaching Controller

Question

I spent a good margin of time searching and working through this problem yesterday without coming up with a solution. Here is the guide I used as reference.

The problem is that the data from the form is not reaching my controller. My goal is to take the form data and pass it to my controller/ model so that I can use the values throughout my code and store them in the database. Below is what I have so far...

In my Browse.cshtml (View)

@model Collect

<form asp-action="Collect" asp-controller="Collect" method="post">
<input type="hidden" asp-for="GameId" name="@game.id"/>
<button type="submit" class="dropdown-item btn btn-block">Default</button>
</form>

In my CollectController.cs (Controller)

using System;
using GameLibrary.me.Models;
using Microsoft.AspNetCore.Mvc;

namespace GameLibrary.me.Controllers
{
public class CollectController  : Controller
{
    [HttpGet]
    public IActionResult Collect()
    {
        return View();
    }

    [HttpPost, ValidateAntiForgeryToken]
    public IActionResult Collect(Collect model)
    {

        Console.WriteLine("**********\n"+model.GameId+"\n**********");

        return Content($"Hello {model.GameId}");
    }    
  }
}

In my Collect.cs (Model)

namespace GameLibrary.me.Models

{
public class Collect
{
    public int GameId { get; set; }
  }
}

EDIT: Here is what my IDE is telling me...

info: Microsoft.AspNetCore.Hosting.Internal.WebHost[1]
  Request starting HTTP/1.1 POST https://localhost:5001/browse?game=eevee application/x-www-form-urlencoded 7

info: Microsoft.AspNetCore.Hosting.Internal.WebHost[2]
  Request finished in 1.0139ms 200

info: Microsoft.AspNetCore.Server.Kestrel[32]
  Connection id "0HLJHIUOU6AKO", Request id "0HLJHIUOU6AKO:00000003": the application completed without reading the entire request body.

Any guidance on what I am doing wrong would be great appreciated... Also can I send multiple values through the hidden field type, or should I make a new hidden field type for each value?

Answer 1

There was a lot of different help here, thanks especially to Kirk Larklin! There were three issues that was preventing my controller from picking up the data.

1. Browse.cshtml was missing the @addTagHelpers... I added the following:

   @addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers
   @addTagHelper *, AuthoringTagHelpers
   

2. My CollectController.cs was missing a route... I added the following:

   [HttpPost, ValidateAntiForgeryToken]
   [Route("Index/Collect")] 
   

3. Finally, I renamed my controller post method from 'Collect' which conflicting with another method to Index and updated the asp-action in my Browse.CSHTML file to match.

   public IActionResult Index(Collect model)
   

Thanks for all the help!
