How to mark documents as marked/deleted in mongodb?

@addison 

In MongoDB, you can mark documents as deleted by adding a "deleted" field to the document and setting it to true. This way, you can keep the actual document in the database but mark it as deleted for reference.

Here is an example of how you can mark a document as deleted in MongoDB:

1. Update the document by adding a "deleted" field and setting it to true:

1
2
3
4

db.collection.update(
   { _id: ObjectId("documentId") },
   { $set: { deleted: true } }
);

1. Optionally, you can also add a "deletedAt" field to track the timestamp when the document was deleted:

1
2
3
4

db.collection.update(
   { _id: ObjectId("documentId") },
   { $set: { deleted: true, deletedAt: new Date() } }
);

1. To query for documents that are marked as deleted, you can use the following query:

1

db.collection.find({ deleted: true });

By following these steps, you can mark documents as deleted in MongoDB without actually removing them from the database. This approach can help maintain a history of deleted documents and easily recover them if needed.
