How to fill select options from custom database in .yaml files using typo3-neos?

i am currently using typo3-neos for my project and i have this problem. i try to make my custom node like this in .yaml file

'TYPO3.Designs:SomeItem':
  superTypes:
    - 'TYPO3.Neos:Content'
  ui:
    group: 'structure'
    label: 'Some Item'
    icon: 'icon-columns'
    inlineEditable: true
    inspector:
      groups:
        document:
          label: 'Item options'
          position: 1
  properties:
    someitem:
    type: string
    defaultValue: 'item1'
    ui:
      label: 'Alignment'
      reloadIfChanged: TRUE
      inspector:
         group: 'document'
         editor: 'TYPO3.Neos/Inspector/Editors/SelectBoxEditor'
         editorOptions:
           values:
             item1:
               label: 'item1'
             item2:
               label: 'item2'
             right:
               label: 'item3'

in this part

editorOptions:
 values:
  item1:
    label: 'item1'
  item2:
    label: 'item2'
  right:
    label: 'item3'

i want to take the data from database, so if in database have 10 items, it will appear 10 options at the editor.

how can i do that? any help is appreciated, thanks

Solution

maybe the code is like this:

add this in your model

<?php
namespace Acme\YourPackage\DataSource;

use TYPO3\Neos\Service\DataSource\AbstractDataSource;
use TYPO3\TYPO3CR\Domain\Model\NodeInterface;

class TestDataSource extends AbstractDataSource {

        /**
         * @var string
         */
        static protected $identifier = 'acme-yourpackage-test';

        /**
         * Get data
         *
         * @param NodeInterface $node The node that is currently edited (optional)
         * @param array $arguments Additional arguments (key / value)
         * @return array JSON serializable data
         */
        public function getData(NodeInterface $node = NULL, array $arguments) {
                return isset($arguments['integers']) ? array(1, 2, 3) : array('a', 'b', 'c');
        }

}

and this is the yaml settings :

questions:
  ui:
    inspector:
      editor: 'Content/Inspector/Editors/SelectBoxEditor'
      editorOptions:
        dataSourceIdentifier: 'questions'
        # alternatively using a custom uri:
        # dataSourceUri: 'custom-route/end-point'
