注意：有与此相关的SO其他问题，但他们没有真正回答了我。 我并不担心服务器端，因为有很多的方式来处理相关节能车型信息（以及如何做到这一点很多例子）。
我需要知道的是：我该如何实现视图代码在创建父模型添加许多儿童模特？
这，当然，会像看到此页上： http://www.yiiframework.com/doc/guide/1.1/en/form.table 。 除代码处理一堆模型，而不是他们的插入的更新 。 这正是我需要的。
总之，我有一个事件的形式，用户可以在其中添加许多约会（每个约会有一天，START_TIME和END_TIME）。 我想渲染使用Yii帮手，所以我得到验证和其他框架的好处事件表单内任命领域。
用户将能够添加多个约会为同一事件而产生的事件。

此解决方案使用esaverelatedbehavior通过sluderitz开发的用于保存相关的模型，你可以在这里下载
http://www.yiiframework.com/extension/esaverelatedbehavior/
正确的语法来呈现什么样的模型（如果他们是儿童模特与否并不重要）的阵列需要讨论的模型的实例。 所以，你会做这样的事情在你的看法：
$child = new ChildModel();
$form->textFieldRow($child,'[]PROPERTY',$dateAtts);
财产是要呈现的文本框的属性的名称。
如果你想用于创建和更新父模式的单一形式，唯一的办法就是实例化一个模拟对象只是呈现形式。 在我的情况下，事件已预约的集合，所以在我的控制器动作我做：
$event->appointments = array(new Appointment);
然后，在图
<?php foreach($model->appointments as $id => $item) : ?>
<div class="appointment">
<?php echo $form->textFieldRow($item,'[$id]day',$htmlAtts); ?>
</div>
<?php endforeach; ?>
我要试试这个扩展名来保存相关机型： https://github.com/yiiext/with-related-behavior
更新
如果你想在$ _ POST父模型阵列中的子模型，你就必须覆盖的name属性。 下面的问题例如...
$form->textFieldRow(
$item,
'[$id]day',
array('name' => "Event[appointments][$id][day]")
);
