Routes in zend framework 2 - module

Question

I am trying hardly to put the routes for some controllers in zend framework 2 and even after I read a lot I can't figure why it still tells me The requested controller could not be mapped to an existing controller class. I have a module named CRM and in the src folder I have Contacts and Companies, each of them having Controller/Form/Model. This is my module.config file:
array(
'controllers' => array(
'invokables' => array(
'CRM\Controller\Contacts' => 'CRM\Controller\ContactsController',
'CRM\Controller\Companies' => 'CRM\Controller\CompaniesController',
),
),
'router' => array(
'routes' => array(
'contacts' => array(
'type' => 'Segment',
'options' => array(
'route' => '/contacts[/:action][/:id]',
'constraints' => array(
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
'id' => '[0-9]+',
),
'defaults' => array(
'controller' => 'Contacts\Controller\Contacts',
'action' => 'index',
),
),
),
'companies' => array(
'type' => 'segment',
'options' => array(
'route' => '/companies[/:action][/:id]',
'constraints' => array(
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
'id' => '[0-9]+',
),
'defaults' => array(
'controller' => 'Companies\Controller\Companies',
'action' => 'index',
),
),
),
),
),
'view_manager' => array(
'template_path_stack' => array(
'contacts' => __DIR__ . '/../view/crm',
'companies' => __DIR__ . '/../view/crm',
),
),
);
Any help would be really appreciated.

Answer 1

If I'm understanding the question and your structure correctly, you need to set up the namespaces in your autoloader config...
public function getAutoloaderConfig()
{
return array(
'Zend\Loader\StandardAutoloader' => array(
'namespaces' => array(
// CRM
__NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
// Contacts
'Contacts' => __DIR__ . '/src/Contacts',
// Companies
'Companies' => __DIR__ . '/src/Companies',
),
),
);
}

At the top of your config you have Controller invokables configuration:
'CRM\Controller\Contacts' => 'CRM\Controller\ContactsController',
The first value in the above is an identifier. This is what you are meant to use within your route definitions. For example your contacts route - try changing the following:
'defaults' => array(
'controller' => 'CRM\Controller\Contacts',
'action' => 'index',
),
