mongodb:到期不起作用

本文介绍了mongodb:到期不起作用的处理方法，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

在猫鼬5.0.6中，我希望此架构在创建后1分钟内使文档过期:

In mongoose 5.0.6, I'm hoping this schema to expire documents 1min after creation:

const InvitationTokenSchema = new Schema( { token: { type: String, required: true }, createdAt: { type: Date, default: Date.now, expires: '1m' }, userId: { type: Schema.Types.ObjectId, ref: 'User' }, }, { usePushEach: true, }, );

但是它根本不起作用-所有文档仅在mongo中保留，不会被删除.

However it simply doesn't work - all documents just persists in mongo, not being removed.

在mongo shell中，getIndexes()显示以下内容:

In mongo shell, getIndexes() shows the following:

[ { "v" : 2, "key" : { "_id" : 1 }, "name" : "_id_", "ns" : "mydb.invitationtokens" }, { "v" : 2, "key" : { "createdAt" : 1 }, "name" : "createdAt_1", "ns" : "mydb.invitationtokens", "expireAfterSeconds" : 60, "background" : true } ]

可能是什么原因?

推荐答案

正如我看到的代码所示，它是正确的. 另外，该值应为 String ，并且您也可以使用'1m'. 您需要将猫鼬更新到最新版本.

As I see you code, its right. Also, the value should be String and you can use '1m' as well. You need to update the mongoose to the latest version.

使用:npm update mongoose
