Issue with Pivot relation on Repeater

Hello i've been following the steps in the documentation: https://filamentphp.com/docs/3.x/forms/fields/repeater#integrating-with-an-eloquent-relationship In order to save a pivot relationship in a repeater field. However as soon as i add the "->relationship()" chain to the repeater field i get the following error: https://flareapp.io/share/v5pKjbM7 Repeater field code:

Forms\Components\Repeater::make('requestTravellers')
                    ->relationship()
                    ->columnSpanFull()
                    ->reorderable(0)
                    ->addActionLabel('Select another Traveller')
                    ->simple(
                        Forms\Components\Select::make('traveller_id')
                            ->relationship(
                                name: 'travellers',
                                titleAttribute: 'first_name',
                                modifyQueryUsing: fn(Builder $query) => $query->where('company_id', Auth::user()->company_id)
                            )
                            ->getOptionLabelFromRecordUsing(fn(Model $record) => "{$record->full_name} | {$record->email}")
                            ->createOptionForm(fn(Form $form) => TravellerResource::form($form))
                            ->required(),
                    )
                    ->grid(2),

Forms\Components\Repeater::make('requestTravellers')
                    ->relationship()

                    ->reorderable(0)
                    ->addActionLabel('Select another Traveller')
                    ->simple(
                        Forms\Components\Select::make('traveller_id')
                            ->relationship(
                                name: 'travellers',
                                titleAttribute: 'first_name',
                                modifyQueryUsing: fn(Builder $query) => $query->where('company_id', Auth::user()->company_id)
                            )
                            ->getOptionLabelFromRecordUsing(fn(Model $record) => "{$record->full_name} | {$record->email}")
                            ->createOptionForm(fn(Form $form) => TravellerResource::form($form))
                            ->required(),
                    )
                    ->grid(2),

Let me know if you need any more info and thanks in advance!

how your model looks? the relationship must named requestTravellers

AsuranDex•9mo ago

It is indeed:

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

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

good, also I dont think simple support relation, it's only for flat array

AsuranDex•9mo ago

Ok, swapped it to a "normal" repeater:

Forms\Components\Repeater::make('requestTravellers')
                    ->relationship()
                    ->columnSpanFull()
                    ->reorderable(0)
                    ->addActionLabel('Select another Traveller')
                    ->schema([
                        Forms\Components\Select::make('traveller_id')
                            ->relationship(
                                name: 'travellers',
                                titleAttribute: 'first_name',
                                modifyQueryUsing: fn(Builder $query) => $query->where('company_id', Auth::user()->company_id)
                            )
                            ->getOptionLabelFromRecordUsing(fn(Model $record) => "{$record->full_name} | {$record->email}")
                            ->createOptionForm(fn(Form $form) => TravellerResource::form($form))
                            ->required(),
                    ])
                    ->grid(2),

Forms\Components\Repeater::make('requestTravellers')
                    ->relationship()
                    ->columnSpanFull()
                    ->reorderable(0)
                    ->addActionLabel('Select another Traveller')
                    ->schema([
                        Forms\Components\Select::make('traveller_id')
                            ->relationship(
                                name: 'travellers',
                                titleAttribute: 'first_name',
                                modifyQueryUsing: fn(Builder $query) => $query->where('company_id', Auth::user()->company_id)
                            )
                            ->getOptionLabelFromRecordUsing(fn(Model $record) => "{$record->full_name} | {$record->email}")
                            ->createOptionForm(fn(Form $form) => TravellerResource::form($form))
                            ->required(),
                    ])
                    ->grid(2),

and looks like the same error is thrown: https://flareapp.io/share/OmVwxJ4P

AsuranDex•9mo ago

AHHH, always a bloody typo xD. I put 'travellers' on the select component and 'traveller' on the pivot model... Thank you, problem solved xD
