Is There A Way To Create An ObjectID From INT In MongoDB?
This question has originally been asked in dba.stackexchange.com. I'm trying to migrate user ids from MySQL to MongoDB and I want to create objectIDs from an int. Is there a way to store INTs inside of ObjectID parts like the random section of ObjectID? Then convert it back to from ObjectID to int.
Ok, there is straightforward approach:
import bson def object_id_from_int(n): s = str(n) s = '0' * (24 - len(s)) + s return bson.ObjectId(s) def int_from_object_id(obj): return int(str(obj)) n = 12345 obj = object_id_from_int(n) n = int_from_object_id(obj) print(repr(obj)) # ObjectId('000000000000000000012345') print(n) # 12345
