Why doesn't laravel instantiate the class in the controller?

Question

Laravel

Hello.
I write this code:
Route

Route::get('article/{id}/edit', 'Cms\[email protected]')->name('cms.blog.article.edit');

Controller

<?php
namespace App\Http\Controllers\Cms;

use App\Http\Controllers\Controller;
use App\Models\Blog\BlogArticle;

class BlogArticleController extends Controller
{
    public function edit(BlogArticle $article)
    {
        dd($article);
    }
}

At the same time, there is nothing in $article. It seems that he did not even understand which model was being addressed.


However, if you do:

<?php
namespace App\Http\Controllers\Cms;

use App\Http\Controllers\Controller;
use App\Models\Blog\BlogArticle;

class BlogArticleController extends Controller
{
    public function edit($article)
    {
        dd(BlogArticle::find($article));
    }
}

That's all right.

Why can this be?

Answer 1

Everything turned out to be very simple:
the name of the parameter should not be $article, but $id. {id} is written in the route
