Where is $node->view set?

Question

views_preprocess_node() contains the following code.

  if (!empty($vars['node']->view) && !empty($vars['node']->view->name)) {
    $vars['view'] = $vars['node']->view;
    $vars['theme_hook_suggestions'][] = 'node__view__' . $vars['node']->view->name;
    if (!empty($vars['node']->view->current_display)) {
      $vars['theme_hook_suggestions'][] = 'node__view__' . $vars['node']->view->name . '__' . $vars['node']->view->current_display;

      // If a node is being rendered in a view, and the view does not have a path,
      // prevent drupal from accidentally setting the $page variable:
      if ($vars['page'] && $vars['view_mode'] == 'full' && !$vars['view']->display_handler->has_path()) {
        $vars['page'] = FALSE;
      }
    }
  }

The part to which I am interested is the line that initializes a variable using the value of $vars['node']->view. I looked at the code executed from the Views module for a node, but I was able to find where $node->view is initialized.

Which of the node hooks (e.g. hook_node_view(), hook_node_load(), hook_node_presave()) would get a valid value for $node->view?

Answer 1

A quick grep of the views module points to the views_plugin_row_node_view class, whose render() function contains the following lines:

$node->view = $this->view;
$build = node_view($node, $this->options['view_mode']);

return drupal_render($build);

So when a node is rendered using the node row plugin, the view is attached to the node object immediately prior to it being passed through node_view(), which is why you see it in the theme preprocess functions.

To actually answer the question (which I missed before), hook_node_view() would get a valid view object, while the others you mentioned wouldn't (I don't think).
