How to save morphToMany relationship during create?

Hi, I'm getting the error "Integrity constraint violation: 1048 Column 'categorizable_id' cannot be null" when laravel tries to run

insert into `categorizables` (`categorizable_id`, `categorizable_type`, `category_id`) values (?, App\Models\Content, 3)

insert into `categorizables` (`categorizable_id`, `categorizable_type`, `category_id`) values (?, App\Models\Content, 3)

The model has the following:

public function categories() : MorphToMany
    {
        return $this->morphToMany(Category::class, 'categorizable');
    }

public function categories() : MorphToMany
    {
        return $this->morphToMany(Category::class, 'categorizable');
    }

And the filament resource form has:

Select::make('categories')
->multiple()
->relationship(titleAttribute: 'name')
->createOptionForm([
    TextInput::make('name')
    ->required(),
    TextInput::make('description')
    ->required(),
    Select::make('parent_id')
    ->options(
        Category::get()
            ->pluck('name', 'id')
    )
])
->preload()
->visible(function (Get $get) {
    return $get('type') === 'post';
})

Select::make('categories')
->multiple()
->relationship(titleAttribute: 'name')
->createOptionForm([
    TextInput::make('name')
    ->required(),
    TextInput::make('description')
    ->required(),
    Select::make('parent_id')
    ->options(
        Category::get()
            ->pluck('name', 'id')
    )
])
->preload()
->visible(function (Get $get) {
    return $get('type') === 'post';
})

Obviously, the relationship can't be saved till after the parent Content model has been saved, but this seems be trying to do that in the reverse order. Any idea how to get round this? I can't believe I'm the first person to encounter this, so it feels like something I've set up wrong. Andy

Solution:

Hmm. That's really wierd. I've just created a test app with the same models, and it works fine. OK, so something odd about my setup, so I'll look into it further. Appreciate your help, @toeknee...

categorizable_id isn't being set, it's passed as null. Are you using the createoptionform first?

No, the categories already exist in this case, and I'm tyring to add the relationship at the same time:

This is a standard resource with a standard create page?
