How do I make a relationship optional?

I have a fieldset with multiple select fields. I want to make sure the relationship is not saved if all the fields inside the fieldset are empty. However, currently Filament is trying to create an empty record for the salary relation. How do I avoid that?

Fieldset::make('listing_salary_id')
                    ->relationship('salary')
                    ->label('Salary Range')
                    ->schema([

Fieldset::make('listing_salary_id')
                    ->relationship('salary')
                    ->label('Salary Range')
                    ->schema([

Solution:

I think there is a saveRelationshipsUsing() or similar method you could use

->nullable() ? Ah it's a Fieldset. Not sure whether that works 🙈

Yeah, that method doesn't exist on Fieldset. I tried ->dehydrated(true) and that doesn't work as well

It should be ->dehydrated(false) if you don't want to save it But then you need to pass a condition via a closure

Doesn't work. It still tries to create a record with empty values.

Is there an example for that in the docs?

Dennis Koch•2y ago

I have no idea, sorry.

I think I fixed it using the saveRelationshipsUsing method:

Maybe wanna use filled() instead of isset() to filter blank states
