我的 Yii 迁移有问题。问题是我迁移了一个在成功迁移后成功完成的代码,我尝试了另一个迁移代码,但这向我展示了迁移代码,我已经迁移的第一个代码和我需要迁移的第二个代码。我只是继续告诉 yii 继续迁移,然后向我发送一个错误,指出迁移已经完成,现在这是我已经完成的迁移,因此无法完成第二次迁移。然后我删除了我的第一个迁移代码并继续迁移我的第二个代码。代码已成功执行,但没有创建表。有没有人对此有解决方案,为什么我的迁移没有完成,是的,我执行的第二个代码,最后一个表位于迁移文件夹中的 safeup() 和 safedown() 上。
这是我的代码,但它再次向我发送错误。实际上我正在从 trackstar 项目中学习 yii。所以,这又是我的代码,我再次将它保存在 up 函数中错误。你能看看吗
public function up()
{
//create the issue table
$this->createTable('tbl_issue', array(
'id' => 'pk',

好吧,迁移代码已粘贴,这是它现在开始向我显示的错误。这里是保管箱的链接,这是它一直显示的错误在此处输入链接描述
