Nested resources

[haringsrob]

Hey,

So I started working out a parent/child nested routing.

While I can do a part of it, I feel it would be better to add parts to filament core to make this work.

Before I dive into it, I would like to check if this is something that you want to be at core, conceptually there are also some different approaches that can be taken.

Here is a dummy implementation of what I am adding:

class ChildPageResource extends NestedResource
{
    public static function getParent(): string
    {
        return ParentPageResource::class;
    }
}

abstract class NestedResource extends Resource
{
    protected static bool $shouldRegisterNavigation = false;

    /**
     * @return class-string<Resource>
     */
    abstract public static function getParent(): string;

    public static function getRoutes(): \Closure
    {
        return function () {
            $parentSlug = static::getParent()::getSlug();

            $slug = static::getSlug();

            Route::name("{$slug}.")
                ->prefix($parentSlug . '/{parentRecord}/' . $slug)
                ->middleware(static::getMiddlewares())
                ->group(function () {
                    foreach (static::getPages() as $name => $page) {
                        Route::get($page['route'], $page['class'])->name($name);
                    }
                });
        };
    }

    public static function getUrl($name = 'index', $params = [], $isAbsolute = true): string
    {
        if (!isset($params['parentRecord'])) {
            $params['parentRecord'] = Route::current()->parameter('parentRecord');
        }

        if (empty($params['parentRecord'])) {
            // Issue here when viewing a resource it no longer has the context, we need to add this information from
            // higher up such as resource pages. This cannot be done from here.
        }

        return parent::getUrl($name, $params, $isAbsolute);
    }
}

The issue for now I am running into is the getURl method.

This should also render a nested breadcrumb, this cannot be done from resource classes and needs changes in the page classes. I would like to avoid the need to change every list/view/create page class.

In addition, conceptually, I wanted to show this in the navigation only when you are in the context.

So the file tree would show:

ParentRecordName

• ChildRecordName (list)

I was able to make this work a bit better by extending custom list/edit/create resource pages, here's an example for reference:

<?php

namespace App\Filament\Nesting;

use Filament\Resources\Pages\CreateRecord;
use Illuminate\Support\Facades\Route;

abstract class NestedCreatePage extends CreateRecord
{
    use NestedPageTrait;

    public mixed $parentRecord;

    public function mount(): void
    {
        $this->parentRecord = Route::current()->parameter('parentRecord');
        parent::mount();
    }
}

<?php

namespace App\Filament\Nesting;

use Filament\Resources\Resource;
use Illuminate\Database\Eloquent\Model;

trait NestedPageTrait
{
    protected function getBreadcrumbs(): array
    {
        /** @var Resource $resource */
        $resource = static::getResource();

        $breadcrumb = $this->getBreadcrumb();

        /** @var Resource $parentResource */
        $parentResource = static::getResource()::getParent();

        /** @var Model $parentModel */
        $parentModel = $parentResource::getModel();

        $parentModelTitle = $parentResource::getGlobalSearchResultTitle($parentModel::find($this->parentRecord));

        return array_merge(
            [$parentResource::getUrl() => $parentResource::getBreadcrumb()],
            [$parentResource::getUrl('edit', ['record' => $this->parentRecord]) => $parentModelTitle],
            [$resource::getUrl('index', ['parentRecord' => $this->parentRecord]) => $resource::getBreadcrumb()],
            (filled($breadcrumb) ? [$breadcrumb] : []),
        );
    }
}

Can make it two levels?

[haringsrob]

I think nested resources are built in now. or there are at least some great packages for this.

[Khant-NyarxG-Next]

I have already try with filament daily article and guava nested plugin
Here is what I want

I have Series, Seasons, Episodes Model
Series have many seasons
Seasons belongto Series and have many episodes
Episodes belongto Seasons

So route will be like this

Series/xx/Seasons/xx/Episodes

Please show me ,If you have a way to archive what I need
