要更新现有模型，您可以使用相同的方法，但不必创建新模型，您可以基于$\u POST['Settings']数组中的键加载模型

要回答有关将3个模型传递给视图的问题，可以不传递它们，但要验证数据并向视图发送正确的错误消息，应将放置在数组中的三个模型传递给数组中的视图

注意：上述示例应按原样工作，但不提供任何验证，以验证模型是否有效或是否正确保存了这些模型查看此链接：

在Yii中，这被认为是更新以创建多个模型的最佳形式

本质上，对于创建，您可以创建一个for循环，生成您希望可见的任意多个输入，并在控制器循环中创建新模型

要更新现有模型，您可以使用相同的方法，但不必创建新模型，您可以基于$\u POST['Settings']数组中的键加载模型

要回答有关将3个模型传递给视图的问题，可以不传递它们，但要验证数据并向视图发送正确的错误消息，应将放置在数组中的三个模型传递给数组中的视图

注意：上面的示例应该按原样工作，但不提供任何验证，以验证模型是否有效或是否正确保存了这些模型。我将给您一个提示，让您知道，这样做可能会使您的生活变得非常复杂

我目前正在使用一个类似于此键值的
EAV
模式表，下面列出了一些您可能会发现困难或不可能的事情：

  • 使用
    CDbCriteria
    mergeWith（）在搜索（）时过滤“值”上的相关元素（或其他）
  • 过滤
    CGridView
    或
    CListView
如果这只是一个非常直接的键值，没有相关的实体方面（我猜这是因为它看起来像设置），那么一种方法是：

  • 为设置表创建一个普通的“设置”
    CActiveRecord
    （您将使用它将条目保存到设置表）
  • 通过扩展
    CFormModel
    创建表单模型，并将其用作表单中的$model
  • 在表单模型中添加一个save（）方法，该方法将使用“设置”模型单独插入键值对。如果键值对未通过设置->验证（）（如果适用），最好使用事务
  • 或者，您可能希望覆盖表单模型的
    getAttributes（）
    ，以便在用户希望编辑条目时返回db数据
我希望这已经足够清楚了。 让我给你一些基本的代码设置。请注意，我没有测试这个。不过，这会给你一个大致的想法

设置模式：

for ( $settings as $i=>$setting ) //Settings would be an array of Models (new or otherwise)

如果你想进一步澄清一点（代码等），请让我知道

PS：对于后代来说，如果其他人对这个和EAV感到疑惑，他们可以检查数据库或选择更合适的数据库系统，例如（有一些扩展）或

我将给你一个提示，让你知道你可能会因此而使你的生活变得非常复杂

我目前正在使用一个类似于此键值的
EAV
模式表，下面列出了一些您可能会发现困难或不可能的事情：

  • 使用
    CDbCriteria
    mergeWith（）在搜索（）时过滤“值”上的相关元素（或其他）
  • 过滤
    CGridView
    或
    CListView
如果这只是一个非常直接的键值，没有相关的实体方面（我猜这是因为它看起来像设置），那么一种方法是：

  • 为设置表创建一个普通的“设置”
    CActiveRecord
    （您将使用它将条目保存到设置表）
  • 通过扩展
    CFormModel
    创建表单模型，并将其用作表单中的$model
  • 在表单模型中添加一个save（）方法，该方法将使用“设置”模型单独插入键值对。如果键值对未通过设置->验证（）（如果适用），最好使用事务
  • 或者，您可能希望覆盖表单模型的
    getAttributes（）
    ，以便在用户希望编辑条目时返回db数据
我希望这已经足够清楚了。 让我给你一些基本的代码设置。请注意，我没有测试这个。不过，这会给你一个大致的想法

设置模式：
