我是yiibie，我使用此链接使用了Yii 1.1: How to upload image(photo), and path entry in database with update functionality，我从这个链接http://www.yiiframework.com/wiki/349/how-to-upload-image-photo-and-path-entry-in-database-with-update-functionality/开始关注所有内容。现在的问题是，当我为Ngo profile上传图像时，在更改一个Ngo个人资料的图像时，其他Ngo的个人资料图像也会发生变化。例如，我有Ngo A图片ngo1.jpg和Ngo B图片ngo2.jpg。当我使用Ngo A更新ngo3.jpg的个人资料时，它会被更改，但也会将Ngo B的图像更改为ngo3.jpg。并且也没有任何Ngo被删除。当我删除它时会出现错误，表示
Error 500: <h1>CDbException</h1>
<p>CDbCommand failed to execute the SQL statement: SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`response_system`.`user_rate_review_ngo`, CONSTRAINT `fk_user_rate_review_ngo_ngo1` FOREIGN KEY (`ngo_id`) REFERENCES `ngo` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION).
