mongodb - How to properly write this query -


using pymongo v2.6, proper way write find query these conditions:

select * tasks processed = 0 , (process_lock_date null or process_lock_date < - 10 minutes) order date_added asc limit 50

basically need write query select 50 records haven't been picked processor yet or haven't been processed , picked more 10 minutes ago (ie pickup unprocessed tasks picked longer time ago , didn't marked processed in case previous processor failed)

any appreciated. thank you.

you need import timedelta , datetime objects first create date object represents datetime 10 minutes ago, use object mongodb query follows:

from datetime import timedelta   date = datetime.datetime.now() - datetime.timedelta(minutes=10) docs = db.collection.find(     {         'processed': 0,         '$or': [             {'process_lock_date': {'$lt': date}},             {'process_lock_date': null}         ]     }).sort({'date_added': 1}).limit(50)  doc in docs:     print(doc)
