'How to change Route Model Binding finding data from id to slug

I have a route like the following.

Route::get('/articles/{articleSlug}' , 
    [App\Http\Controllers\ArticleController::class, 'single']);

And the method of single() at ArticleController class goes here:

public function single($slug)
{
    $article = Article::where('slug',$slug)->first();
    $article->increment('viewCount');

    return view('home.article',compact('article'));
}

Now I wish to use Route Model Binding for finding this data from the articles table based on the column slug. But as I know, Route Model Binding finds data based on the id. So how to change Route Model Binding finding data from id to slug ONLY for ArticleController.php (meaning that the other Controller classes can work with id as route model binding)?

Solution 1:[1]

Your controller is already set up, all you need to do is change your variable name to $slug in the route, and I believe that should be enough:

Route::get('/articles/{slug}' , [App\Http\Controllers\ArticleController::class, 'single']);

Solution 2:[2]

change your route to this:

Route::get('/articles/{article:slug}' , [App\Http\Controllers\ArticleController::class, 'single']);

and then inject the Article model to your controller function and let laravel do the rest for you:

public function single(Article $article)
    {
        $article->increment('viewCount');
        return view('home.article',compact('article'));
    }

you can customize route model bindings directly in the route definition:

  1. past given code in app/model/Article.php:

    public function getRouteKeyName() { return 'slug'; }

2.when you use slug change route to

 Route::get('/articles/{article:slug}' , [App\Http\Controllers\ArticleController::class, 'single']);

  1. to use id sample change slug to id

    Route::get('/articles/{article:id}' , [App\Http\Controllers\ArticleController::class, 'single']);

you can add bind method to your model boot() like this

public function boot()
{
    Route::bind('article', function ($value) {
        return Article::where('slug', $value)->firstOrFail();
    });
 
}
