Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
$article = Article.find(...);

// Update one of the attributes
$article->title = "New Title";

// And only that updated attribute is persisted to the db
$article->save();
  // "UPDATE articles SET title = 'New Title' WHERE id = 1"

部分更新能力可以减少应用程序与数据库之间的数据传输，��
�高性能。
