Remove old records in mongodb based on Month

Question

I am trying to delete Older records present in my collection .

I have a collection named \"user_track\" , which consists of data in this format shown below

Answer 1

I have found a solution to address this issue .

var date=new Date();
date.setDate(date.getDate() - 1);
db.user_track.remove({"access_time":{"$lt":date}});

I will make this run automatically by putting these lines in a bash file and scheduling that script using a cron tab .

Please share your views if this is a valid solution or not ??
