Preload the list of entities which will appear in the view.

TODO: When the date is coming in through a relationship, the nid of the view is not the right node to use: we need the related node. Need to sort out how that should be handled.

Code

public function pre_render($values) {

  // Preload each entity used in this view from the cache.
  // Provides all the entity values relatively cheaply, and we don't
  // need to do it repeatedly for the same entity if there are
  // multiple results for one entity.
  $ids = array();
  foreach ($values as $row) {

    // Use the $id as the key so we create only value per entity.
    $id = $row->{$this->field_alias};

    // Node revisions need special loading.
    if ($this->view->base_table == 'node_revision') {
      $this->entities[$id] = node_load(NULL, $id);
    }
    else {
