modifyQueryUsing based on request - action resets query

Hey all, Use case: - In the /view it gets all categories that don't have parent ids - When you click on a record it takes you to route /{record}/view - In /{record}/view it fetches all subcategories where parent_id = {record} Problem: - In /{record}/view when I click on a Table action, the query resets and the action doesn't perform. Here's the code:

    public static function table(Table $table): Table
    {
        return $table
            //other code
            ->recordAction('view', Pages\ListProductCategories::route('/{record}'))
            ->actions([
                Tables\Actions\ActionGroup::make([
                    Tables\Actions\EditAction::make(),
                    Tables\Actions\DeleteAction::make(),
                ])
            ])
            ->modifyQueryUsing(fn (Builder $query): Builder =>
            $query->when(request()->route('record'), function ($query) {
                return $query->where('parent_id', request()->route('record'));
            }, function ($query) {
                return $query->where('parent_id', null);
            }));
    }  
    
    public static function getPages(): array
    {
        return [
            'index' => Pages\ListProductCategories::route('/'),
            'view' => Pages\ListProductCategories::route('/{record}/view'),
        ];
    }

    public static function table(Table $table): Table
    {
        return $table
            //other code
            ->recordAction('view', Pages\ListProductCategories::route('/{record}'))
            ->actions([
                Tables\Actions\ActionGroup::make([
                    Tables\Actions\EditAction::make(),
                    Tables\Actions\DeleteAction::make(),
                ])
            ])
            ->modifyQueryUsing(fn (Builder $query): Builder =>
            $query->when(request()->route('record'), function ($query) {
                return $query->where('parent_id', request()->route('record'));
            }, function ($query) {
                return $query->where('parent_id', null);
            }));
    }  
    
    public static function getPages(): array
    {
        return [
            'index' => Pages\ListProductCategories::route('/'),
            'view' => Pages\ListProductCategories::route('/{record}/view'),
        ];
    }

I'm wondering if I'm doing anything wrong or approaching the wrong way. Thanks!

Solution:

Add a $record property to your ListProductCategories page (not resource) because that es what you named to param.

You should never rely on request() in Livewire context. Use a property on the Livewire component instead.

Thanks @Dennis Koch
In the context of a Filament resource, what property would you suggest we use to check if a $record is set? 👌🏻

Use $livewire->record inside the Closure then.
