mongodb:到期不起作用 [英] mongodb: expires not working

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
