Usage

This extension provides Laravel Nova web interface for the application configuration setup. It provides a single form for the configuration parameters setup and restore defaults feature.

This extension relies on illuminatech/config package for the actual configuration management. Make sure you are familiar with illuminatech/config package before attempting to use this one.

First of all, you need to setup persistent configuration for your application, specifying the particular configuration items, which should be editable from Nova admin panel. For example:

<?php

namespace App\Providers;

use Illuminatech\Config\Providers\AbstractPersistentConfigServiceProvider;

class PersistentConfigServiceProvider extends AbstractPersistentConfigServiceProvider
{
    protected function items(): array
    {
        return [
            'app.name' => [
                'label' => __('Application name'),
                'rules' => ['sometimes', 'required'],
            ],
            'app.debug' => [
                'label' => __('Debug mode enabled'),
                'rules' => ['sometimes', 'required', 'boolean'],
                'cast' => 'boolean',
            ],
            'app.env' => [
                'label' => __('Application environment'),
                'rules' => ['sometimes', 'required'],
            ],
            // ...
        ];
    }

    // ...
}

Do not forget to register your persistent config service provider in "providers" section at "config/app.php":

<?php

return [
    // ...
    'providers' => [
        // ...
        App\Providers\PersistentConfigServiceProvider::class,
    ],
    // ...
];

Next, you should register the \Illuminatech\NovaConfig\NovaConfig tool within Nova at your NovaServiceProvider:

<?php

namespace App\Providers;

use Laravel\Nova\NovaApplicationServiceProvider;

class NovaServiceProvider extends NovaApplicationServiceProvider
{
    public function tools()
    {
        return [
            new \Illuminatech\NovaConfig\NovaConfig(),
            // ...
        ];
    }
}

Once it is done the new tool called "Settings" will appear at the Nova sidebar menu, leading to the configuration setup form.

Field Configuration

The form field to be used for the particular configuration item management defined via \Illuminatech\Config\Item::$options. By default, a regular text input will be used for the item. In case \Illuminatech\Config\Item::$cast is set to "bool" or "boolean", the checkbox field will be used. The dropdown (e.g. select) input will be rendered in case 'options' array provided. You can manually define the exact Nova field to be used, using 'component' key. For example:

<?php

namespace App\Providers;

use Illuminatech\Config\Providers\AbstractPersistentConfigServiceProvider;

class PersistentConfigServiceProvider extends AbstractPersistentConfigServiceProvider
{
    protected function items(): array
    {
        return [
            'app.name' => [
                'label' => __('Application name'),
                'rules' => ['sometimes', 'required'],
                // renders regular text input
            ],
            'app.debug' => [
                'label' => __('Debug mode enabled'),
                'rules' => ['sometimes', 'required', 'boolean'],
                'cast' => 'boolean', // renders checkbox input
            ],
            'app.env' => [
                'label' => __('Application environment'),
                'rules' => ['sometimes', 'required'],
                'options' => [ // dont't mess `Item::$options` with drop-down options!
                    'options' => [ // renders drop-down input
                        ['value' => 'production', 'label' => 'Production'],
                        ['value' => 'local', 'label' => 'Local'],
                        ['value' => 'testing', 'label' => 'Testing'],
                    ],
                ],
            ],
            'app.description' => [
                'label' => __('Application description'),
                'rules' => ['sometimes', 'required'],
                'options' => [
                    'component' => 'textarea-field', // renders textarea input
                ],
            ],
            // ...
        ];
    }

    // ...
}

In general any Nova field, which allowed to be used for resource management form (e.g. create/update record form), could be used for the particular config item. However, some fields require extra configuration parameters, which you'll have to setup manually. In order to get a proper configuration options, you can setup the field, you are interested with, for some of your Nova resources, then navigate to this resource's creation form and search in browser network console for the XHR request to URL like http://example.com/nova-api/your-resource-name/creation-fields. Its response contains JSON with key "fields", within which you can find the proper configuration for your field.

Access Restriction

You can restrict access to the application configuration setup form using regular tool's canSee() method provided by Nova. For example:

<?php

namespace App\Providers;

use Laravel\Nova\NovaApplicationServiceProvider;

class NovaServiceProvider extends NovaApplicationServiceProvider
{
    public function tools()
    {
        return [
            (new \Illuminatech\NovaConfig\NovaConfig())
                ->canSee(function ($request) {
                    return $request->user(config('nova.guard'))->is_super_admin;
                }),
            // ...
        ];
    }
}
