Permission issue in Laravel - laravel

Question

I am facing problem regarding permission
Argument 1 passed to App\Providers\AuthServiceProvider::App\Providers{closure}() must be an instance of App\Providers\User, instance of App\User given, called in C:\xampp\htdocs\Tweety\vendor\laravel\framework\src\Illuminate\Auth\Access\Gate.php on line 473 (View: C:\xampp\htdocs\Tweety\resources\views\tweet.blade.php)
I am just working to show delete button only on those tweets made by the authenticated users
my controller
public function destroy(Tweet $tweet)
{
$tweet->delete();
Session::flash('success');
return redirect()->route('tweets.index')->with(['message' => 'Tweet Deleted']);
}
my user model
public function tweets()
{
return $this->hasMany(Tweet::class)->latest();
}
my blade
#can('delete',$tweet)
<form action="{{ route('tweets.destroy',$tweet->id) }}" method="POST">
#csrf
#method('DELETE')
<button type="submit" class="btn btn-danger">Delete</button>
</form>
#endcan
AuthServiceProvider
public function boot()
{
$this->registerPolicies();
Gate::define('delete', function (User $user , Tweet $tweet){
return $tweet->user->is($user);
});
}
Any help will be appreciated

Answer 1

It looks like a namespace issue and didn't import User model's namespace correctly.
<?php
namespace App\Providers;
use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
use App\User; // looks like you're missing this line.
use App\Tweet;
class AuthServiceProvider extends ServiceProvider
{
/**
* The policy mappings for the application.
*
* #var array
*/
protected $policies = [
'App\Model' => 'App\Policies\ModelPolicy',
];
/**
* Register any authentication / authorization services.
*
* #return void
*/
public function boot()
{
$this->registerPolicies();
Gate::define('delete', function (User $user , Tweet $tweet){
return $tweet->user->is($user);
});
}
}

You would need to change:
#can('delete', $tweet)
to:
#can('delete')
