Laravel Backpack select_and_order: how to make options list dependent on model being edited - laravel-backpack

Question

I have a select_and_order field that works in my
use App\Models\Tool;
class ProjectCrudController extends CrudController
{
protected function setupCreateOperation()
{
CRUD::addField([
'name' => 'tools'
'type' => 'select_and_order',
'options' => Tool::get()->pluck('selector','id'),
]);
Now the possible tools are dependent on the type of project, so instead of returning all tools to options as above, I would like something like
CRUD::addField([
'name' => 'tools'
'type' => 'select_and_order',
'options' => Tool
::projectTypeFilter($this->crud->model->type)
->pluck('selector','id'),
]);
But the new query returns [] because - as far as I can see - $this->crud->model is not hydrated.
protected function setupUpdateOperation()
{
CRUD::addField([
'name' => 'naam',
'type' => 'select_and_order',
'options' => dump($this->crud->getModel()),
]);
}
shows
App\Models\Project {#1779 ▼

How can I have the model hydrated?

I think what you're looking for is not $this->crud->getModel() (which will get you the Eloquent model class), but $this->crud->getCurrentEntry() which will get you:
false, if the model has not been hydrate (eg. inside setupCreateOperation(), where there is no current entry to speak of);
the current entry for that Eloquent model, if present (eg. inside setupUpdateOperation();
