Route call wrong method

Sorry. I’m completely blind.

The problem is that under the route
$routes->delete('(:any)', 'Media::delete/$1');
fits
DELETE admin/media and DELETE admin/media/directory

You need to change the order of the routes.

first
$routes->delete('directory/(:any)', 'Media::directory/$1');
next
$routes->delete('(:any)', 'Media::delete/$1');

You're using
route_to('admin/media/files')
But the route is completely different
admin/media/files/(:any)/details

The route_to function does not find it.
In addition, you have an undefined segment, so route_to will also throw an exception.

With your route, it is more correct to define the route alias.
for example

PHP Code:

$routes->get('admin/media/files/(:any)/details', 'Controller::method', ['as' => 'files.details']);
// and call 
route_to('files.details', 123); // admin/media/files/123/details 


But since your segment is dynamic and the code is executed on the client, you cannot use route_to().
And it is better to form the URL manually.
