在AfterDelete回调中清空$ this-＆gt;数据？

Question

我想在删除记录后删除记录的关联文件。 但是在删除回调方法之后我得到$ this-＆gt;数据为空。

Answer 1

您必须在删除操作之前将文件名存储在变量中。

Answer 2

我同意，但文档有点不清楚：

// perhaps after deleting a record from the database, you also want to delete
// an associated file
public function afterDelete() {
    $file = new File($this->data['SomeModel']['file_path']);
    $file->delete();
}

Answer 3

实际上并非空洞。在我认为的文档中，这只是一个错误。试试这个：

// perhaps after deleting a record from the database, you also want to delete
// an associated file
public function afterDelete() {
    $file = new File($this->info['SomeModel']['file_path']);
    $file->delete();
}
