A document in MongoDB is the same as a record in SQL databases.
MongoDB-д баримт бичиг нь SQL өгөгдлийн сангийн мөртэй адилхан.
Insert Into Collection – Цуглуулга руу өгөгдөл оруулах #
To insert a record, or document as it is called in MongoDB, into a collection, we use the insert_one() method.
Мөр оруулах, эсвэл баримт бичгийг оруулахыг MongoDB-д цуглуулга оруулах гэж нэрлэдэг, цуглуулга оруулахыг тулд insert_one() аргыг ашигладаг.
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.
Example – Жишээ #
Insert a record in the “customers” collection:
“customers” цуглуулгад өгөгдөл оруулах:
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)
Return the _id Field – _id талбарыг буцаах #
The insert_one() method returns a InsertOneResult object, which has a property, inserted_id, that holds the id of the inserted document.
insert_one() арга нь оруулсан баримт бичгийн id-г хадгалсан InsertOneResult объектыг буцаана. Энэ объект нь inserted_id шинж чанарыг агуулдаг.
Example – Жишээ #
Insert another record in the “customers” collection, and return the value of the _id field:
mydict = { "name": "Peter", "address": "Lowstreet 27" }
x = mycol.insert_one(mydict)
print(x.inserted_id)
If you do not specify an _id field, then MongoDB will add one for you and assign a unique id for each document.
In the example above no _id field was specified, so MongoDB assigned a unique _id for the record (document).
Insert Multiple Documents – Олон Баримт бичгүүд нэмэх #
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:
Example #
import pymongo
myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]
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)
The insert_many() method returns a InsertManyResult object, which has a property, inserted_ids, that holds the ids of the inserted documents.
Insert Multiple Documents, with Specified IDs – Олон баримт бичгийг тодорхойлсон ID-уудтайгаар оруулах #
If you do not want MongoDB to assign unique ids for your document, you can specify the _id field when you insert the document(s).
Remember that the values has to be unique. Two documents cannot have the same _id.
Example – Жишээ #
import pymongo
myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]
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"},
{ "_id": 6, "name": "Sandy", "address": "Ocean blvd 2"},
{ "_id": 7, "name": "Betty", "address": "Green Grass 1"},
{ "_id": 8, "name": "Richard", "address": "Sky st 331"},
{ "_id": 9, "name": "Susan", "address": "One way 98"},
{ "_id": 10, "name": "Vicky", "address": "Yellow Garden 2"},
{ "_id": 11, "name": "Ben", "address": "Park Lane 38"},
{ "_id": 12, "name": "William", "address": "Central st 954"},
{ "_id": 13, "name": "Chuck", "address": "Main Road 989"},
{ "_id": 14, "name": "Viola", "address": "Sideway 1633"}
]
x = mycol.insert_many(mylist)
#print list of the _id values of the inserted documents:
print(x.inserted_ids)
