Customizing the editor

The editor on the right of the layout is a Livewire component, Awcodes\Panelist\Livewire\RecordEditor. It fills the resource's form, saves new and existing records, and deletes them. To customize that behavior, extend the component and point your Panelist page at the subclass.

Creating a custom editor

Extend RecordEditor and override the hooks you need:

use Awcodes\Panelist\Livewire\RecordEditor;

class PostEditor extends RecordEditor
{
    protected function mutateFormDataBeforeCreate(array $data): array
    {
        $data['user_id'] = auth()->id();

        return $data;
    }

    protected function afterSave(): void
    {
        // ...
    }
}

Then set the page's $editor property to your class:

class ManagePosts extends PanelistPage
{
    protected static string $resource = PostResource::class;

    protected static string $editor = PostEditor::class;
}

Panelist registers the editor with Livewire automatically, so there is nothing else to configure. The class must extend RecordEditor.

Available hooks

The editor supports the same hooks as Filament's create and edit pages:

mutateFormDataBeforeSave() applies when an existing record is saved, and mutateFormDataBeforeCreate() when a new record is created. The beforeSave() and afterSave() hooks run for existing records, and beforeCreate() and afterCreate() for new ones.

To stop a save from a hook, throw Filament\Support\Exceptions\Halt.

What the editor handles for you

Whether or not you customize it, the editor:

• checks the resource's canCreate(), canEdit() and canDelete() authorization before creating, saving or deleting;
• only loads records returned by the resource's getEloquentQuery(), so tenancy and other query scoping apply;
• saves relationship fields, such as a multiple Select using relationship(), for new and existing records;
• wraps saves in a database transaction when the panel enables databaseTransactions().
