Python - Pymongo Insert and Update Documents

Question

Using PyMongo, I have a set of dict's in a list that I'd like to submit to my MongoDB. Some of the items in the list are new entries, and some are to update.

Example:

On Server Database:

[{"_id" : 1, "foo" : "bar}]

To send to database:

[{"_id" : 1, "foo" : "HELLO"}, {"_id" : 2, "Blah" : "Bloh"}]

I'm currently using the following to insert documents, but how would I do something like stated above? Any help is appreciated!

collection.insert(myDict)

Answer 1

Use upsert option:

from pymongo import MongoClient
cl = MongoClient()
coll = cl["local"]["test2"]

data = [{"_id" : 1, "foo" : "HELLO"}, {"_id" : 2, "Blah" : "Bloh"}]
for d in data:
    coll.update({'_id':d['_id']}, d, True)

Answer 2

You can also use save

import pymongo
con = pymongo.MongoClient()
coll = con.db_name.collection_name

docs = [{"_id" : 1, "foo" : "HELLO"}, {"_id" : 2, "Blah" : "Bloh"}]

for doc in docs:
    coll.save(doc)
