Select Relationship Modify Query Using

Hi everyone, When I create an auction I select a car but the dropdown only shows the cars that don't belongs to another auction (I use modifyQueryUsing), so this works when I create. The issue is when I try to update an auction, I cannot see my car selected in the dropdown list because that car already belongs to the same auction that I'm updating so how can I fix that?

Select::make('car_id')
  ->label('Car')
  ->relationship(
      name: 'car',
      titleAttribute: 'name',
      modifyQueryUsing: fn (Builder $query) =>             $query->whereDoesntHave('auction')
      )
  ->required(),

Select::make('car_id')
  ->label('Car')
  ->relationship(
      name: 'car',
      titleAttribute: 'name',
      modifyQueryUsing: fn (Builder $query) =>             $query->whereDoesntHave('auction')
      )
  ->required(),

Solved

Select::make('car_id')
  ->label('Car')
  ->relationship(
      name: 'car',
      titleAttribute: 'name',
  )
  ->options(function (?Model $record): array {
      return Car::query()
          ->doesntHave('auction')
          ->orWhere('id', $record?->car_id)
          ->get()
          ->pluck('name', 'id')
          ->toArray();
  })
  ->required()

relationship() accepts more parameters one of which is modifyQueryUsing. Maybe using it it's possible to achieve the same result

@Garrita use can check using $operation in ->modifyQueryUsing: fn (Builder $query, string $operation). It'll return the operation like create, edit, ... etc. You can modify according to that.

I didn't know that we could inject those parameters in modifyQueryUsing omg, thanks!
