Fetch relational data in custom page

How can I fetch the relational data in personable.full_name?

public function form(Form $form): Form
    {
        return $form
            ->schema([
                TextInput::make('title')
                    ->autofocus()
                    ->required(),
                TextInput::make('personable.full_name')
                    ->required(),
            ])
            ->statePath('data')
            ->model($this->ticket);
    }

    public Ticket $ticket;

    public function mount(int | string $record): void
    {
        $this->ticket = Ticket::findOrFail($record);
        $this->form->fill($this->ticket->attributesToArray());
    }

User.php model:

    public function tickets(): MorphMany
    {
        return $this->morphMany(Ticket::class, 'personable');
    }

Ticket.php model:

    public function personable(): MorphTo
    {
        return $this->morphTo();
    }

When I’m using the same code with an info list personable.full_name is working. But why can’t I populate the field in edit mode in the form? What am I doing wrong?

Dot syntax doesn’t eager load the relationship in forms like it does for tables and infolists. Some fields like select support a relationship, but in the context of a form it doesn’t always work. Ie when creating a record there is no relationship yet. You can wrap the field in a Group layout component and set a relationship on that though.

That explains it... By a group, do you mean a fieldset? can you give me an example of how you do that?

Section::make(‘blah’)
    ->relationship(‘relation’)
    ->schema([])

Section::make(‘blah’)
    ->relationship(‘relation’)
    ->schema([])

All the layout components support relationship. And there is a Group component which isn’t documented for some reason.
