I\'m doing a simple insert into Mongo...
db.notes.insert({ title: \"title\", details: \"note details\"})
After the note document is inserte
It's better to use insert_one() or insert_many() instead of insert(). Those two are for the newer version. You can use inserted_id to get the id.
myclient = pymongo.MongoClient("mongodb://localhost:27017/")
myDB = myclient["myDB"]
userTable = myDB["Users"]
userDict={"name": "tyler"}
_id = userTable.insert_one(userDict).inserted_id
print(_id)
Or
result = userTable.insert_one(userDict)
print(result.inserted_id)
print(result.acknowledged)
If you need to use insert(), you should write like the lines below
_id = userTable.insert(userDict)
print(_id)
You just need to assigne it to some variable:
someVar = db.notes.insert({ title: "title", details: "note details"})
updated; removed previous because it wasn't correct
It looks like you can also do it with db.notes.save(...)
, which returns the _id after it performs the insert.
See for more info: http://api.mongodb.org/python/current/api/pymongo/collection.html
One of the cool things about MongoDB is that the ids are generated client side.
This means you don't even have to ask the server what the id was, because you told it what to save in the first place. Using pymongo the return value of an insert will be the object id. Check it out:
>>> import pymongo
>>> collection = pymongo.Connection()['test']['tyler']
>>> _id = collection.insert({"name": "tyler"})
>>> print _id

The answer from Tyler does not work for me. Using _id.inserted_id works
>>> import pymongo
>>> collection = pymongo.Connection()['test']['tyler']
>>> _id = collection.insert({"name": "tyler"})
>>> print(_id)
<pymongo.results.InsertOneResult object at 0x0A7EABCD>
>>> print(_id.inserted_id)

Newer PyMongo versions depreciate insert
, and instead insert_one
or insert_many
should be used. These functions return a pymongo.results.InsertOneResult
or pymongo.results.InsertManyResult
object.
With these objects you can use the .inserted_id
and .inserted_ids
properties respectively to get the inserted object ids.
See this link for more info on insert_one
and insert_many
and this link for more info on pymongo.results.InsertOneResult
.
