how to pass parameters to relationship .parameter passed to relationship from controller to model in laravel.but now working

Question

in my controller parameter passed to posts function in user model with construct method . i want the users that have posts and posts should be according to the parameter.

class MyController extends Controller
{
    private $user;
    public function __construct(User $getuser)
    {
        $this->user = $getuser;
    }
    public function index($id = 2)
    {
        $posts = $this->user->posts($id);
        $user = User::whereHas('posts')->find($id);
        return $user;
    }
}

in my user model parameter accessed and passed to relationship .

class User extends Authenticatable
{
    use Notifiable;
    
    protected $fillable = [
        'name', 'email', 'password',
    ];

    function posts($id)
    {
        return $this->hasMany('App\Post')->where('id',$id);
    }
}

it works when use like this

"return $this->hasMany('App\Post')->where('id',1);"

but not working with passed parameter. getting this error

"Symfony\Component\Debug\Exception\FatalThrowableError Too few arguments to function App\User::posts(), 0 passed in C:\xampp\htdocs\blog\vendor\laravel\framework\src\Illuminate\Database\Eloquent\Concerns\HasAttributes.php on line 415 and exactly 1 expected"

You're making life difficult for yourself and not allowing the framework to do the heavy lifting.

web.php

Define a route that accepts a User identifier

Route::get('/users/{user}', 'UserController@show');

User.php

public function posts() {
    return $this->hasMany(App\Post::class);
}

UserController.php

public function show(User $user) {
    return view('users.view', compact('user');
}

resources/views/users/view.blade.php

ddd($user->posts);
