Is it possible to have a Pager config file in a module's config directory?

I'm working on a blog module for CI4 and I want to customize the pagination links. 

In the doc it says the pager view can be overridden in app/Config/Pager.php, and in module's doc it says you can have a Config directory for your module, but there's not much examples other than how to load a custom config file.

Can I have a Pager config file in my module? Something like my-module/Config/Pager.php? I can't make it work. Maybe I need to override the pager service to load my module's config?

I'm back with this problem...

I just reinstalled a new test site with CI 4.0.2 and I'm still stuck with this problem. For my app to use the custom pagination template from my module, I need to edit app/Config/Pager.php because CI won't load my-module/Config/Pager.php.

In the debug toolbar, I can see that only APPPATH/Config/Pager.php is loaded. Is this a bug? Did we forget to check if there's a Pager.php file in a module's config directory?

Encountering same issue in 4.6.0 with automatic pagination using CodeIgniter's model.

Config/Autoload

PHP Code:

public $psr4 = [
    APP_NAMESPACE => APPPATH,
    'Admin' => ROOTPATH . 'admin',
]; 


App\Model\UserModel

PHP Code:

class UserModel extends Model {
    protected $table = 'user';
    protected $primaryKey = 'user_id';
    protected $returnType = 'object';
    protected $allowedFields = ['user_group_id', 'username', 'email', 'password', 'firstname', 'lastname', 'image', 'status'];
} 


App\Config\Pager

PHP Code:

public array $templates = [
    'default_full'  => 'CodeIgniter\Pager\Views\default_full',
    'default_simple' => 'CodeIgniter\Pager\Views\default_simple',
    'default_head'  => 'CodeIgniter\Pager\Views\default_head',
]; 


Admin\Config\Pager

PHP Code:

public array $templates = [
    'default_full'  => 'Admin\Views\common\pager_full',
    'default_simple' => 'Admin\Views\common\pager_simple',
]; 


Admin\Controllers\User

PHP Code:

$model = model('UserModel');
$data = [
    'rows' => $model->paginate(),
    'pager' => $model->pager->links(),
]; 


App\Config\Pager views are loaded instead of those defined in Admin\Config\Pager

All module views load fine except for pagination.

---

Loading the module config before the model gets around the issue...

PHP Code:

config('Admin\Pager'); 


But shouldn't Admin\Config\Pager be loaded automatically?

https://github.com/codeigniter4/CodeIgni...es.php#L67

PHP Code:

    /**
    * --------------------------------------------------------------------------
    * Auto-Discovery Rules
    * --------------------------------------------------------------------------
    *
    * Aliases list of all discovery classes that will be active and used during
    * the current application request.
    *
    * If it is not listed, only the base application elements will be used.
    *
    * @var list<string>
    */
    public $aliases = [
        'events',
        'filters',
        'registrars',
        'routes',
        'services',
    ]; 


Module configs are not autoloaded. Registrars are, so you can make registrar in that module and your config should be overrriden.
With Pager config I have not tested this though

Example to override App supportedLocales, maybe you can use this approach

PHP Code:

<?php namespace Modules\Language\Config;

class Registrar
{
    public static function App(): array
    {
        $output = [];

        if (isset($_SERVER['REQUEST_URI'])) {
            $db = db_connect();

            if ($db->tableExists('languages')) {
                $results = $db->table('languages')->where('published', 1)->get()->getResultObject();

                foreach ($results as $result) {
                    if (!isset($output['supportedLocales'])) {
                        $output['supportedLocales'] = [];
                    }

                    if (!in_array($result->language, $output['supportedLocales'])) {
                        $output['supportedLocales'][] = $result->language;
                    }

                    if (!empty($result->is_default)) {
                        $output['defaultLocale'] = $result->language;
                    }
                }
            }
        }

        return $output;
    }
} 


@includebeer How I got around the problem below. Replace "Admin" with your module's namespace.

\Admin\Controllers\BaseController

PHP Code:

public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger) {
    parent::initController($request, $response, $logger);
    config('Admin\Pager');
} 


Could not determine why module Pager config is not automatically loaded 

---

Module configs are not autoloaded.

admin/Config/Routes.php gets autoloaded in my module

Well... $aliases list is config classes which are autoloaded

PHP Code:

public $aliases = [
        'events',
        'filters',
        'registrars',
        'routes',
        'services',
    ]; 


Actually in that case, just add Pager to this list

Actually in that case, just add Pager to this list

No obvious effect. Still had to call config('Admin\Pager') before model to make module templates load.

Just now realizing admin/Config/App.php is not loaded either (eg: base_url() returns app base, not module base). No point beating that horse 

We thought modularization was a slim alternative to multi-app single install.

• Latter seems like overkill for separating widely-related front/back ends.
  
• While the prior is missing built-in module-specific config autoloading.
  

Maybe we'll modify the core to achieve the latter. Toss out a pull-request for the powers-that-be if it seems like a community fit  

Opinion: Autoloading modular config for respective classes by default should be an option.

@davis.lasis thanks for referencing registrars. After a fresh night's sleep, that is superior to our previous workarounds.

PHP Code:

<?php

namespace Admin\Config;

class Registrar
{
    public static function Pager(): array
    {
        return [
            'templates' => [
                 'default_full'  => 'Admin\Views\common\pager_full',
                 'default_simple' => 'Admin\Views\common\pager_simple',
            ],
            'perPage' => 10,
        ];
    }
} 


While digging around CodeIgniter\Config\Factories::getOptions() we spotted "registrar" in code comments, and recalled your mention thereof, sending us down the path.
