如何更新 mongoose 中 createdAt 字段的 expires 属性以避免文档被删除？

Question

I am trying to add account verification to this app and I have set a user account that has been created but not verified to delete itself after 30 seconds using.

createdAt: {
  type: Date,
  default: Date.now,
  index: {
    expires: 30,
  },
},

But now I am looking for a way to prevent the document from being deleted after 30 seconds but I haven't found a working solution.

Answer 1

This should do the trick for you:

Let's say this is User model.

await User.syncIndexes();

The other thing you will need to update in User model is:

createdAt: {
  type: Date,
  default: Date.now,
},

Mongoose uses MongoDB TTL indexes to expire documents, see https://docs.mongodb.com/manual/core/index-ttl/

If the indexed field in a document is not a date or an array that holds a date value(s), the document will not expire.

If a document does not contain the indexed field, the document will not expire.

So to prevent the document expiring you might unset the field, set it to a non-date value, or set the date into the far future.
