I was asking for modules.php not Module.php/module.php. I mean the place where you have stored array of modules like this:

$modules = [
    'admin' => [
        'className' => 'Suzuki\Module\Admin\Module',
        'path' => '../Module/Admin/Module.php',

Im not sure but try to add path key.

Can you help me with 2 things:

• If i register a new module just like frontend, what is the link to access it, in this case is "backend" module , i think i have accessed backned with wrong link like this : localhost/projectname/backend

• Second, can you tell me how to create others module just like frontend , for example : backend , in case i generate application with devtools please.

Thank you so much

Im not sure but try to add path key.

The default router behaviour is only suitable for single module application. You need to add routes yourself to access actions in multi module. Read about here:

https://forum.phalcon.io/discussion/6416/multi-module-routing-default-behaviour

about dev tools - im not using it myself to generate modules. Im just doing them myself. Not so hard stuff.

I also had the same problem ... after having searched and searched within the code generated by the DevTool I found the bug. In the app/config/routes.php file the following line of code

$namespace = str_replace('Module','Controllers', $module["className"]);

should be replaced with

$namespace = preg_replace('/\bModule\b/u', 'Controllers', $module["className"]);

The problem is that the strings of the type "Projectname\Modules\Backend\Module" (the standard from DevTool) were mistakenly replaced with "Projectname\Controllerss\Backend\Controllers", with my script instead we replace only whole word "Model" and not the string "Model" inside Models word. Later would certainly found problems also in the default module (frontend) routes.

Sorry the bug is just solved in the 3.0.3 version

$namespace = preg_replace('/Module$/', 'Controllers', $module["className"]);
