class party_plugin_row_attached_entity in Party 8.2

Plugin class for displaying party attached entities with entity_view.

Although we have a lot in common with entity_plugin_row_entity_view, there's nothing useful we can inherit from it as it's fixed to a single entity type.

Row style plugin for displaying entities attached to a party. This will produce multiple rows per party, and is mostly intended for views which are filtered to a single party, thus showing a list of all of a party's attached entities.

class party_plugin_row_attached_entity extends views_plugin_row {
  public function options_form(&$form, &$form_state) {
    $form['note'] = array(
      '#markup' => t('Some options may go here in due course.'),
    );
    return $form;
  }

  /**
   * Add the fields we need to the query.
   */
  function query() {

    // Add the party id.
    $this->field_alias_pid = $this->view->query
      ->add_field('party', 'pid');

    // Add fields from {party_attached_entity} for loading entities.
    $this->field_alias_eid = $this->view->query
      ->add_field('party_attached_entity', 'eid');
    $this->field_alias_entity_type = $this->view->query
      ->add_field('party_attached_entity', 'entity_type');
  }

  /**
   * Use entity_load() to load all entities at once if they aren't loaded yet.
   */
  function pre_render($results) {
    $entities_to_load = array();
    $this->entities = array();
    foreach ($results as $index => $result) {
      $entity_type = $result->{$this->field_alias_entity_type};
      $id = $result->{$this->field_alias_eid};

      // We group this first by type.
      $entities_to_load[$entity_type][$index] = $id;
    }

    // party_preprocess_entity() to find.
