"CDbCommand未能执行SQL语句: SQLSTATE[23000]:“图书中的示例

Question

日安！面对这样的问题，当创建问题(http://test.com/book/ima/index.php?ssue/create&pid=1)时得到以下错误：

CDbCommand failed to execute the SQL statement: SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`trackstar`.`tbl_issue`, CONSTRAINT `fk_issue_owner` FOREIGN KEY (`owner_id`) REFERENCES `tbl_user` (`id`) ON DELETE CASCADE). The SQL statement executed was: INSERT INTO `tbl_issue` (`project_id`, `name`, `description`, `type_id`, `status_id`, `owner_id`, `requester_id`, `create_time`, `create_user_id`, `update_time`, `update_user_id`) VALUES (:yp0, :yp1, :yp2, :yp3, :yp4, :yp5, :yp6, :yp7, :yp8, :yp9, :yp10)

/var/www/yii/framework/db/CDbCommand.php(357)

345         {
...

我试过这样做：http://www.yiiframework.com/forum/index.php/topic/11953-cdbcommand-failed-to-execute-the-sql-statement-sqlstate23000-integrity-constraint-violation/

 public function rules()
{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('name, project_id', 'required'),
        .....
        ........
    );
}

它不起作用。帮助解决问题，我想进一步学习，但因为它，我不能。

从您给出的链接和错误中，可能是由于以下原因造成了约束违规：

The user_id attempting to be inserted is not associated with a valid tbl_user.id value in the tbl_user table.

错误信息是如此明显。您尝试在tbl_issue中插入一个包含外键user_id的记录，该记录在tbl_user上不存在。
