How do I update a Mongo document after inserting it?

Let's say I insert the document. post = { some dictionary } mongo_id = mycollection.insert(post) Now, let's say I want to add a field and update it. How do I do that? This doesn't seem to work..... post = mycollection.find_one({"_id":mongo_id}) post['newfield'] = "abc" mycollection.save(post)
In pymongo you can update with: mycollection.update({'_id':mongo_id}, {"$set": post}, upsert=False) Upsert parameter will insert instead of updating if the post is not found in the database. Documentation is available at mongodb site. UPDATE For version > 3 use update_one instead of update: mycollection.update_one({'_id':mongo_id}, {"$set": post}, upsert=False)
