问题 - 我想保存从表单提交的数据，当我将其保存到MySQL时收到错误 -
SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'updated' cannot be null
但是我已经将更新列的默认值设置为0000-00-00 00:00:00，默认情况下它必须采用默认值。
我正在使用＆＃34; prepersist＆＃34;在将代码保存到MySQL之前添加代码的技术。
以下是我的＆＃34; prepersist＆＃34;从中生成上述错误的代码段 -
public function setBeforeInsertData() {
$this->added = new \DateTime();
}
我已经使用以下代码来克服错误，因为我知道这是一个错误的方法。
public function setBeforeInsertData() {
$this->added = new \DateTime();
$this->updated = new \DateTime();
}
以下是相应表格的实体 -

您的实体类应具有以下注释：@ORM\HasLifecycleCallbacks()。您的方法应该有@ORM\PrePersist注释。更多信息：http://symfony.com/doc/current/book/doctrine.html#lifecycle-callbacks
