本文介绍了Perl mongodb删除记录问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
使用以下代码，删除指定的文档.
use the following code, delete the specified document.
sub delete_post{
my $post_id = shift;
my $post_to_delete = $posts->find_one({"_id" => $conn->oid($post_id)})->{_id};
$posts->remove({"_id" => $post_to_delete});
}
如果使用此代码:
sub delete_post{
my $post_id = shift;
$posts->remove({"_id" => $conn->oid($post_id)});
}
删除所有文档.
mongodb不能接受oid作为删除文档的条件吗?
Does mongodb cannot accept the oid as criteria to delete document?
推荐答案
使用MongoDB :: OID方法创建_id对象，而不是$ conn-> oid;
Use the MongoDB::OID method to create _id object instead of $conn->oid;
sub delete_post{
my $post_id = shift;
my $oid = MongoDB::OID->new(value => $post_id);
$posts->remove({"_id" => $oid});
$db->log->insert({"removed_post" => $post_id});
}
