JSON issue with MongoDB ObjectId

Question

As you know MongoDB documents has at least one ObjectId named _id . It's not possible to convert a document contains an ObjectId to JSON . currently I have two solutions to convert this document to JSON :

del doc['_id']

or create a new document with a string instance of that field.

What it just works when I know which field contains ObjectId . What to do if I have multiple ObjectId and I don't know what are they?

Answer 1

MongoDB returns a BSON (not a JSON ) document, so actually you want to convert a BSON document into JSON document.
