Question

{
 "teachers" : [
               {"name": "Lucy", "id": 3, course: "history"}, 
               {"name": "Mark", "id": 6, "course": "maths"}, 
               {"name": "Joan", "id": 20, course: "French"} 
               ] 
}

This document is in the “school” collection. I have been trying to access these imbedded documents using

db.school.find({teachers:{id:3}}) 

I also tried

db.school.find({teacher.id:3})

but I understand it isn’t working since mongo can’t look inside an embedded array.
Therefore I would like to turn these imbedded documents into individual documents. That is, remove the embedding and the “teachers” key, creating an individual document for each teacher.

The final “school” collection would be

{"name": "Lucy", "id": 3, "course": "history"}, 
{"name": "Mark", "id": 6, "course": "maths"}, 
{"name": "Joan", "id": 20, "course": "French"}

i would like to do it with python and save the new documents into a collection.

EDIT

this is what i have come up with for now:

import pymongo
import sys

connection = pymongo.Connection("mongodb://localhost", safe=True)

db = connection.hello
shows = db.school

for doc in db.school:
    for indiv in "teachers":
            try:
            db.individual.insert(indiv)
        except:
            print "Unexpected error", sys.exc_info()[0]

Answer 1

school_records = db.school.find()
for i in school_records:
    for teacher in i['teachers']:
        db.individual.insert(teacher)

What about this?
