 多模型的复合表单
 ==================================
 
-When dealing with some complex data, it is possible that you may need to use multiple different models to collect
-the user input. For example, assuming the user login information is stored in the `user` table while the user profile
-information is stored in the `profile` table, you may want to collect the input data about a user through a `User` model 
-and a `Profile` model. With the Yii model and form support, you can solve this problem in a way that is not much
-different from handling a single model.
+当需要处理复杂数据，很可能你需要使用多个不同的模型来收集用户提交的数据。
+举例来说，假设用户登录信息保存在 `user` 表，但是用户基本信息保存在 `profile` 表，
+你可能需要同时使用 `User` 模型和 `Profile` 模型来获取用户登录信息和基本信息。
+使用 Yii 提供的模型和表单支持，解决这样的问题和处理单一模型并不会有太大的区别。
 
-In the following, we will show how you can create a form that would allow you to collect data for both `User` and `Profile`
-models.
