Question

我在Propel 1.6.9上运行，之前的开发人员最近更新了文件，因为我在笔记本电脑上生成正确的文件时仍然遇到一些问题。除了在尝试删除某些内容时遇到的一个问题，一切顺利。

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[23000]: Integrity constraint violation: 1451 Cannot delete or update a parent row: a foreign key constraint fails (`db000_app/file_meta`, CONSTRAINT `file_meta_FK_1` FOREIGN KEY (`case_id`) REFERENCES `agency_costs` (`id`))' in /var/www/vhosts/10/154462/webspace/httpdocs/domain/vendor/propel/propel1/runtime/lib/connection/DebugPDOStatement.php:90 

Stack trace:

#3 [internal function]: BaseAgencyCo in /var/www/vhosts/10/154462/webspace/httpdocs/domain/vendor/propel/propel1/runtime/lib/util/BasePeer.php on line 149

调用删除功能的代码：

$case = AgencyCostsQuery::create()->findPk($_POST["DeleteId"]);

if ($case !== null)
{
  $case->deleteFiles();
  $case->delete();
}

如上所述，这在文件更新之前工作得很好。数据库已更改：已向agency_costs添加了两列。

有关如何克服此错误的任何想法？

Answer 1

问题是由数据库中约束的定义引起的。约束设置为限制删除和更新。将此更改为级联解决了我的问题。

由于Integrity约束违规，Propel无法删除
