The Panelizer module attaches panels to entities, providing default panels and allowing each panel to be configured independently by privileged users.

Code

function panelizer_entity_view_alter(&$build, $entity_type) {
  static $recursion_prevention = array();

  // Prepare variables.
  $handler = panelizer_entity_plugin_get_handler($entity_type);

  // Safety check in case the entity can't be loaded.
  if (!$entity) {
    return;
  }
  list($entity_id, $revision_id, $bundle) = entity_extract_ids($entity_type, $entity);

  // If the requested view mode does not exist, check if a substitute is
  // assigned, otherwise rendering will fall back to 'default' and we should
  // check that one instead.
  $view_mode = $handler
    ->get_view_mode($build['#view_mode'], $bundle);

  // Make sure the bundle + view mode is actually panelized!
  if (!$handler
    ->is_panelized($bundle . '.' . $view_mode)) {
    return;
  }

  // Also verify that the configuration exists. This may happen if a display is
  // improperly configured.
