In Laravel Backpack need to list users with specific role - roles

Question

please check the details below, where I have a Organizations module. Where I can create a organization with a owner with role "organization".
The third input is a dropdown where we need to select the user with role "organization"
protected function addOrganizationFields(){
$this->crud->addFields([
[
'name' => 'name',
'label' => __('Organization Name'),
'type' => 'text',
],
[
'name' => 'billing_information',
'label' => __('Billing Information'),
'type' => 'textarea',
],
[
'name' => 'owner_id',
'label' => __('Organization Owner'),
'type' => 'select2',
'entity' => 'owners_list',
'attribute' => 'name',
'model' => "App\User",
]
]);
}
In the organization module I wrote this code.
public function owners_list(){
return User::whereHas('roles', function($q){
$q->where('name', 'member');
})->get();
}
in the Organization model relationship I wrote this.
But showing the list of all users in the drop-down.
Can anybody please tel me what is to be done.

You can eliminate options from your select2 field using the “options” attribute mentioned in the docs - https://backpackforlaravel.com/docs/4.1/crud-fields
[
'name' => 'owner_id',
'label' => __('Organization Owner'),
'type' => 'select2',
'entity' => 'owners_list',
'attribute' => 'name',
'model' => "App\User",
// add something like this
'options' => (function ($query) {
return $query->whereHas('roles', function($q){
$q->where('name', 'member');
})->get();
}), // force the related options to be a custom query, instead of all(); you can use this to filter the results show in the select
