Laravel resource route being assigned incorrect parameter name

Question

Using Laravel 5.6, I'm generating a resource controller with the following command:

php artisan make:controller SkusController --resource --model=Sku

The generated controller file has correctly type-hinted methods. For example:

<?php

namespace App\Http\Controllers;

use App\Sku;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class SkusController extends Controller
{
    /**
     * Display the specified resource.
     *
     * @param  \App\Sku  $sku
     * @return \Illuminate\Http\Response
     */
    public function show(Sku $sku)
    {
        //
    }
}

Now, I add a resource route to my routes file, like this:

Route::resource('skus', 'SkusController');

However, in my routes list, the named parameter in these routes is appearing as skus, not sku, causing the route-model binding not to work. The $sku variable in the controller methods turns out empty.

For example, here's the URI for the show methods entry in the php artisan route:list output:

skus/{skus}

Alternatively, I followed the same process for a products resource, and the URI is correct:

products/{product}

In that case the route-model binding works as expected since the controller variable is called $product.

I think I can manually change the parameter name, but I'm just wondering why that should be necessary. Shouldn't the route be generated correctly in the first place?

You can use it like:

Route::resource('skus', 'SkusController')->parameters(['skus' => 'sku']);

It can be used in Route model binding. like

public function update(Request $request, Sku $sku)
    {
        $sku->update(); // data to be updated
    }

where Sku will be your Model name.
