Hi,

Invalid data provided to SELECT helper

[internal function]: Phalcon\Tag\Select::selectField(Array, NULL)

from the controller, you have to provide role list to the view :

// in your controller action
$roles = Role::find([  // I find more convenient to use plural here
    'columns' => 'id, name',
    'order' => 'name ASC'
]);
$this->view->setVar('roles', $roles);

// in your view
 <td> {{ select("name","roles","using": ["id", "name"])}} </td>

I think you have a typo:

// in your controller action
$roles = Role::find([  // I find more convenient to use plural here
    'columns' => 'id, name',
    'order' => 'name ASC'
]);
$this->view->setVar('roles', $roles);

// in your view
 <td> {{ select("name", roles ,"using": ["id", "name"])}} </td>
