Relation Manager with Parameters

[mstfkhazaal]

I have a Relation Manager with 2 parameters (level,lbl)

<?php

namespace App\Filament\Resources\Assessment\AssessmentManagerResource\RelationManagers;

use Filament\Forms;
use Filament\Resources\Form;
use Filament\Resources\RelationManagers\RelationManager;
use Filament\Resources\Table;
use Filament\Tables;
use Illuminate\Database\Eloquent\Builder;

class QuestionsRelationManager extends RelationManager
{
    protected static string $relationship = 'Questions';
    protected static ?string $recordTitleAttribute = 'name';
    public string $lbl;
    public int $level;

    public function __construct($id = null, $level, $lbl)
    {
        $this->level = $level;
        $this->lbl = $lbl;
        parent::__construct($id);
    }

    /**
     * @return string
     */
    public static function getPluralModelLabel(): string
    {
        return self::$lbl;
    }

    public static function form(Form $form): Form
    {
        return $form
            ->schema([
                Forms\Components\TextInput::make('title')
                    ->required()
                    ->maxLength(255),
            ]);
    }

    public static function table(Table $table): Table
    {
        return $table
            ->columns([
                Tables\Columns\TextColumn::make('title'),
            ])
            ->filters([
                //
            ])
            ->headerActions([
                Tables\Actions\CreateAction::make(),
            ])
            ->actions([
                Tables\Actions\EditAction::make(),
                Tables\Actions\DeleteAction::make(),
            ])
            ->bulkActions([
                Tables\Actions\DeleteBulkAction::make(),
            ])->reorderable('order');
    }


    /**
     * @throws \Exception
     */
    protected function getTableQuery(): Builder
    {
        return parent::getTableQuery()->where('level_id', $this->level);
    }
}

i want to pass this parameters

 public static function getRelations(): array
    {
        $level = 1;
        $id = null;
        $lbl = 'Level 1';
        return [
            app(QuestionsRelationManager::class, [
                'id' => $id,
                'level' => $level,
                'lbl' => $lbl,
            ]),
        ];
    }

Filament\Resources\Pages\EditRecord::Filament\Resources\Pages\Concerns\{closure}(): Argument #1 ($manager) must be of type Filament\Resources\RelationManagers\RelationGroup|string, App\Filament\Resources\Assessment\AssessmentManagerResource\RelationManagers\QuestionsRelationManager given

The relation manager is a Livewire component, so you shouldn't override the constructor like a regular class. I think the best way to achieve what you want is by emiting a Livewire event from the page component to the relation manager:

I've read the documentation but I'm facing a problem that I have more than one instance
I update the code but not work i use mount

QuestionsRelationManager

<?php

namespace App\Filament\Resources\Assessment\AssessmentManagerResource\RelationManagers;

use Filament\Forms;
use Filament\Resources\Form;
use Filament\Resources\RelationManagers\RelationManager;
use Filament\Resources\Table;
use Filament\Tables;
use Illuminate\Database\Eloquent\Builder;

class QuestionsRelationManager extends RelationManager
{
    protected static string $relationship = 'Questions';
    protected static ?string $recordTitleAttribute = 'title';

    public int $level;

    public function mount($level)
    {
        $this->level = $level;
    }

......

    /**
     * @throws \Exception
     */
    protected function getTableQuery(): Builder
    {
        return parent::getTableQuery()->where('level_id', $this->level);
    }
}

Resource AssessmentManagerResource

 public static function getRelations(): array
    {
        $list=[];
       for ($i = 1; $i <= 10; $i++) {
               $list[]= app(QuestionsRelationManager::class, [
               'level' => $i,
            ]);
        }
        return   $list;
    }

can you please help me figure out how to rewrite the getRelations() function, in the logic that i wrote above but ofcourse that works as i am just trying to explain what i want it to do.

It is not possible to do this at the moment as you cant pass params to a relation manager.

[mstfkhazaal]

Well, I hope you will add this feature in the next update if this is possible
