MongoDB Insert 📥
Insert Into Collection
To insert a record, or document as it is called in MongoDB, into a collection, we use the insert_one() method.
✨ Insert Document
The first parameter of the insert_one() method is a dictionary containing the name(s) and value(s) of each field in the document you want to insert.
python
import pymongo
myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]
mydict = { "name": "John", "address": "Highway 37" }
x = mycol.insert_one(mydict)
print(x.inserted_id)🔢 Insert Multiple Documents
To insert multiple documents into a collection in MongoDB, we use the insert_many() method.
The first parameter of the insert_many() method is a list containing dictionaries with the data you want to insert:
python
mylist = [
{ "name": "Amy", "address": "Apple st 652"},
{ "name": "Hannah", "address": "Mountain 21"},
{ "name": "Michael", "address": "Valley 345"},
{ "name": "Sandy", "address": "Ocean blvd 2"},
{ "name": "Betty", "address": "Green Grass 1"},
{ "name": "Richard", "address": "Sky st 331"},
{ "name": "Susan", "address": "One way 98"},
{ "name": "Vicky", "address": "Yellow Garden 2"},
{ "name": "Ben", "address": "Park Lane 38"},
{ "name": "William", "address": "Central st 954"},
{ "name": "Chuck", "address": "Main Road 989"},
{ "name": "Viola", "address": "Sideway 1633"}
]
x = mycol.insert_many(mylist)
# print list of the _id values of the inserted documents:
print(x.inserted_ids)🆔 Insert With Specified ID
If you do not want MongoDB to assign unique ids for you document, you can specify the _id field when you insert the document(s).
python
mylist = [
{ "_id": 1, "name": "John", "address": "Highway 37"},
{ "_id": 2, "name": "Peter", "address": "Lowstreet 27"},
{ "_id": 3, "name": "Amy", "address": "Apple st 652"},
{ "_id": 4, "name": "Hannah", "address": "Mountain 21"},
{ "_id": 5, "name": "Michael", "address": "Valley 345"}
]
x = mycol.insert_many(mylist)
# print list of the _id values of the inserted documents:
print(x.inserted_ids)✨ Pro Tip
If you do not specify an _id field, then MongoDB will add one for you and assign a unique id for each document.
