Laravel Permissions and Roles with Gate/Can - laravel

Question

at the moment i do a tutorial called "roles and permissions in laravel" from codecourse.com.
In part 4 of the tutorial i have the problem i get everytime the result true.
If i ask for the permission "edit posts" it should show me true, if i ask for the permission "delete posts" it should show me false.
I checked the database relationship, but there is no relationship between the user and the permission "delete posts".
Only if i ask for a permission that not exist like "blabla" (i mean not exist in the database) i got false.
I believe he is only checking is there a permission with this name and not checking have the user the permission.
web.php
Route::get('/', function (\illuminate\Http\Request $request) {
$user = $request->user();
dump($user->can("delete posts"));});
HasPermissionTrait.php
trait HasPermissionsTrait {
public function hasRole(...$roles)
{
foreach ($roles as $role) {
if ($this->roles->contains('name', $role)) {
return true;
}
}
return false;
}
public function hasPermissionTo($permission) {
//Check has permission through role
return $this->hasPermission($permission);
}
protected function hasPermission($permission) {
return (bool) $this->permissions->where('name', $permission->name);
}
public function roles() {
return $this->belongsToMany(Role::class, 'users_roles');
}
public function permissions() {
return $this->belongsToMany(Permission::class, 'users_permissions');
}
PermissionsServiceProvider.php
public function boot()
{
Permission::get()->map(function ($permission) {
Gate::define($permission->name, function ($user) use ($permission) {
return $user->hasPermissionTo($permission);
});
});
}
/**
* Register the application services.
*
* #return void
*/
public function register()
{
//
}

On this image you can see the Auth. There is no permission "delete posts". But you can see the Gate is giving true.

i got already the answer. Thank you to tykus from laracasts.com
tykus:
Looks like your trait might have a mistake:
protected function hasPermission($permission) {
return (boolean) $this->permissions->where('name', $permission->name);
}
$this->permissions->where('name', $permission->name) returns a Builder instance, and an object cast to a boolean always is true.
You probably need to return a count or first - something that would be falsey if there was no permission, e.g.
protected function hasPermission($permission) {
return (boolean) $this->permissions->where('name', $permission->name)->count();
}
