How can we help you?

I have nested resource, and can get parent record data.
is there a way to get record in child ListRecords / Index page from child Resource?

Child Resource :

class TargetSubProgressResource extends Resource
{
    public array $data = [];

    public function mount(int | string $record): void
    {
        $this->record = $this->resolveRecord($record);
     }

    public static function getPages(): array
    {
        return [
            'index' => Pages\ListTarget::route('/'),
            'create' => Pages\CreateTarget::route('/create'),
            'edit' => Pages\EditTarget::route('/{record}/edit'),
        ];
    }
}

Child ListRecords :

class ListTarget extends ListRecords
{
    public function mount(): void
    {
        dd( $this->parent ) ???
    }
}

Parent Resource :

use App\Filament\Resources\TargetSubProgressResource;
use App\Models\TargetProgress;

class TargetProgressResource extends Resource
{
    ...
    public function table(Table $table): Table
    {
        return $table
            ->query(function () {
                ....
            })
            ->columns([
                ...
            ])
            ->filters([
                ...

                    ->button()
                    ->url(function (TargetProgress $record) {
                        return TargetSubProgressResource::getUrl('subprogress.index', [
                                    'parent' => $record,
                                ]);
                    }),
}

Child Resource :

use App\Models\TargetProgress;

class TargetSubProgressResource extends Resource
{
    public static ?string $parentModel = TargetProgress::class;

    public static function getPages(): array
    {
        return [
            'subprogress.index' => Pages\ListTargetSubProgress::route('/{parent}/subprogress/'),
            'subprogress.create' => Pages\CreateTargetSubProgress::route('/{parent}/subprogress/create'),
            'subprogress.edit' => Pages\EditTargetSubProgress::route('/{parent}/subprogress/{record}/edit'),
        ];
    }
}

Child ListRecords :

use App\Http\Traits\HasParent;

class ListTargetSubProgress extends ListRecords 
{
    use HasParent;

    protected static string $resource = TargetSubProgressResource::class;

    protected function getHeaderActions(): array
    {
        return [
            Actions\CreateAction::make()
                ->label('New')
                ->icon('heroicon-m-plus')
                ->url(
                    fn (): string => static::getResource()::getUrl('subprogress.create', [
                        'parent' => $this->parent,
                    ])
                ),
        ];
    }
}

Trait ( using Hashids https://github.com/vinkla/laravel-hashids ) :

<?php

namespace App\Http\Traits;
 
trait HasParent
{
    public $parent;

    public function mount(): void
    {
        if (request()->route('parent') && request()->route('subparent')) {
            $parent = $this->getParentModel()::findByHashid(request()->route('parent'));
            $subparent = $this->getSubparentModel()::findByHashid(request()->route('subparent'));

            if ( $parent && $subparent ) {
                $this->parent = $parent;
                $this->subparent = $subparent;
            }
        }
    }

    public static function getParentModel(): string
    {
        $parentModel = static::getResource()::$parentModel;
 
        if (!isset($parentModel)) {
            throw new Exception('Parent model is not set for '.static::class);
        }
 
        return $parentModel;
    }
}

I have nested resource
How are you doing this?

[gzai]

I'm sorry if it's not clear, I've found the answer and fixed the code above.

I was able to do this using the HasManyThrough relationship, in this case to get the children of the children.

For example, if you want to get the comments from the posts, and want to put them in a general comments resource:

    public function posts(): HasMany
    {
        return $this->hasMany(Post::class);
    }

    public function comments(): HasManyThrough
    {
        return $this->hasManyThrough(Comment::class, Post::class);
    }

In CommentResource:

    public static function getEloquentQuery(): Builder
    {
        return Filament::getTenant()
            ->comments()
            ->getQuery()
            ->select('comments.*')
            ->with(['post']) // Optional
            ->withTrashed();
    }
