更改管理员/内容形式

在节点上添加了“由...更改”后，我现在需要在“作者”列旁边的node_admin_content表单上（在admin/content）上显示修改了每个节点的用户。

我设法通过更改node.admin.inc并仅添加两行代码来轻松解决此问题：

...
'changed_by' => t('Changed By'),
...

...
'changed_by' => theme('username', array('account' => user_load($node->changed_by))),
...

当然，这不是适当的解决方案，因为它会更改内核。

因此，我然后尝试通过以下方式更改表格：

function hook_form_node_admin_content_alter(&$form, &$form_state, $form_id) { 
  $form['admin']['nodes']['#header']['changed_by'] = t('Changed By');
  // ... ?
}

使用，dpm我可以看到表单在选项中有节点。问题在于这是将节点渲染为表选项的结果。我无权访问原始节点，也不想重新执行节点获取查询以获取“更改者”信息。我想在表单挂钩中执行此操作不会在正确的层中解决它。还是？

那么，改变node_admin_content表单以添加更多存在于节点上的数据的好方法是什么？

坏消息是，在检查了代码之后，表单更改层才是真正执行此操作的唯一位置。您的方法几乎是正确的。

好消息是，Drupal在整个页面加载期间实现了各种静态缓存，从而最大程度地减少了返回数据库的需求。因此，尽管更改内容表可能看起来很麻烦，但实际上并没有带来明显的性能损失。

以下代码（或类似代码）应该有效；请参阅注释以获取有关缓存问题的更多信息：

function MYMODULE_form_node_admin_content_alter(&$form, &$form_state, $form_id) {
  // Load the nodes. This incurrs very little overhead as 
  // "$nodes = node_load_multiple($nids);" has already been run on these
  // nids in node_admin_nodes(). The static cache will be used instead of
  // another db query being invoked
  $nodes = node_load_multiple(array_keys($form['admin']['nodes']['#options']));

  // Grab a list of all user ids that have been responsible for changing the node
  $uids = array();
  foreach ($nodes as $node) {
    $uids[] = $node->changed_by;
  }

  // Filter out duplicates (one user may have been the last to change more than one node)
  $uids = array_unique($uids);

  // Load a list of all involved users in one go. This is about as performant
  // as this is going to get, as you're going to need the user objects one
  // way or the other for the call to theme_username
  $users = user_load_multiple($uids);

  // Add another column to the table header
  $form['admin']['nodes']['#header']['changed_by'] = array('data' => t('Changed by'));

  // Loop through the rows in the table and add the changed by column
  foreach ($form['admin']['nodes']['#options'] as $nid => $row) {
    // Grab the user related to this node.
    $this_user = $users[$nodes[$nid]->changed_by];

    // Add data for the new column
    $form['admin']['nodes']['#options'][$nid]['changed_by'] = theme('username', array('account' => $this_user));
  }
}

上面的代码在内容管理页面上产生了一个漂亮的闪亮新列，如下所示：

只需将View替换为admin / content，然后添加所需的任何字段即可。 管理员视图甚至可以为您完成此任务。

主题稍有偏离，但是此答案显示了如何以编程方式执行此操作（例如，通过将其作为模块更新添加到MY_MODULE.install文件中）。

如果要在最后一个现有字段之前添加新字段，则需要做更多的工作。将其合并到$ view-> display ['default']-> display_options ['fields']数组的末尾。

    function MY_MODULE_update_7101(){
        // update the admin/content view, need to do it manually because it's
        // set by admin_views module
        $view_name = 'admin_views_node';
        $view = views_get_view($view_name, TRUE);

        //  add the relationship
        $view->display['default']->display_options['relationships']['uid_1']['id'] = 'uid_1';
        $view->display['default']->display_options['relationships']['uid_1']['table'] = 'node_revision';
        $view->display['default']->display_options['relationships']['uid_1']['field'] = 'uid';
        $view->display['default']->display_options['relationships']['uid_1']['label'] = 'Revision User';
        // new column settings
        $new_column = array(
            'name_1' => array(
                'id' => 'name_1',
                'table' => 'users',
                'field' => 'name',
                'relationship' => 'uid_1',
                'label' => 'Updated By',
            )
        );
        // need to use this because array_splice by itself resets 'name_1' key to '0'
        // see http://php.net/manual/en/function.array-splice.php#56794
        $temp_array = array_splice( $view->display['default']->display_options['fields'] , 0, 7);
        $view->display['default']->display_options['fields'] = array_merge($temp_array , $new_column, $view->display['default']->display_options['fields']);

        views_save_view($view);
    }
