ZF2 routing ignores namespace - php

Question

I am having an issue with zf2 routing. I am using skeleton example https://github.com/zendframework/ZendSkeletonApplication/blob/master/module/Application/config/module.config.php, but when I tying to access http://localhost/admin/ or http://localhost/admin/answers I am getting 404 with message:
A 404 error occurred
Page not found.
The requested controller could not be mapped to an existing controller class.
Controller:
Index(resolves to invalid controller class or alias: Index)
No Exception available
From error message I think router ignores __NAMESPACE__. Maybe someone could help me find solution to my problem?
I have used https://github.com/zendframework/ZFTool to create module and controllers.
My file structure is:
module/Admin
├── config
│   └── module.config.php
├── Module.php
├── src
│   └── Admin
│   └── Controller
│   ├── AnswersController.php
│   └── IndexController.php
└── view
└── admin
├── answers
│   └── index.phtml
└── index
└── index.phtml
My module.config.php:
return array(
'controllers' => array(
'invokables' => array(
'Admin\Controller\Answers' => 'Admin\Controller\AnswersController',
'Admin\Controller\Index' => 'Admin\Controller\IndexController',
),
),
'router' => array(
'routes' => array(
'admin' => array(
'type' => 'literal',
'options' => array(
'route' => '/admin',
'defaults' => array(
'__NAMESPACE__' => 'Admin\Controller',
'controller' => 'Index',
'action' => 'index',
),
),
'may_terminate' => true,
'child_routes' => array(
'default' => array(
'type' => 'segment',
'options' => array(
'route' => '/[:controller[/:action]]',
'constraints' => array(
'controller' => '[a-zA-Z][a-zA-Z0-9_-]*',
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
),
'defaults' => array(
),
),
),
),
),
),
),
'view_manager' => array(
'template_path_stack' => array(
'admin' => __DIR__ . '/../view',
),
),
);
If I am changing: '\__NAMESPACE__' => 'Admin\Controller', 'controller' => 'Index', to 'controller' => 'Admin\Controller\Index' I can access Index controller, but not Answers .
Additional info:
I found strange behavior of skeleton application. I have downloaded fresh skeleton application and this configuration works. If I am going to localhost/application/index or localhost/application/answers it works as accepted. But if I am changing Application module name to Admin and changing router configuration (replacing all application to admin and Application to Admin) and config stops working. Can anyone explain this? Maybe Application module works as default in skeleton applications?
I am using Zend Framework 2.2.4.

Answer 1

add above default key
'answers' => array(
'type' => 'Zend\Mvc\Router\Http\Literal',
'options' => array(
'route' => '/answers',
'defaults' => array(
'controller' => 'Admin\Controller\Answers',
'action' => 'index',
),
),
),
if that not help try comment default key
So maybe try wildcards ?
'application' => array(
'type' => 'segment',
'options' => array(
'route' => '/[:controller][/:action][/:id]',
'constraints' => array(
'controller' => '[a-zA-Z][a-zA-Z0-9_-]*',
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
'id' => '[0-9]+',
),
'defaults' => array(
'controller' => 'Application',
'action' => 'index',
),
),
'may_terminate' => true,
'child_routes' => array(
'default' => array(
'type' => 'Wildcard',
'options' => array(
),
),
),
),
it's only lead not complete solution

Answer 2

Set in Module.php
public function onBootstrap(MvcEvent $e)
{
$eventManager = $e->getApplication()->getEventManager();
$moduleRouteListener = new ModuleRouteListener();
$moduleRouteListener->attach($eventManager);
}

I'am not 100% sure of what you are trying to achieve but this may help you in a way. In case you have a variable controller param I would set up my routes like this:
'router' => array(
'routes' => array(
'admin' => array(
'type' => 'segment',
'options' => array(
'route' => '/admin[/:controller[/:action]]',
'constraints' => array(
'controller' => '[a-zA-Z][a-zA-Z0-9_-]+',
'action' => '[a-zA-Z][a-zA-Z0-9_-]+',
),
'defaults' => array(
'controller' => 'Admin\Controller\Admin',
'action' => 'index',
),
),
),
),
),
When redirecting you would need to specify the controller and the action this way though.
return $this->redirect()->toRoute('admin', array('action' => 'newAction', 'controller' => 'someOtherController'));
URL View-Helper equivalent:
$this->url('admin', array('action' => 'newAction', 'controller' => 'someOtherController'));
EDIT:
Zend framework2 merges all config fiels trough your models and provides the Router Module with the array you have configured. In fact you could extend the Router class and alter it to your likeing.
As you can probably see it actually is not "mandatory" to provide the router with the namespace of each module within your config files. The router has your invoked Controllers and can "track" them via the zf2 naming convention.
EDIT2: I forgot to add some constraint's to the route can you try it with the updated route configuration again?
