monggoDB 기초

기초 코드

from pymongo import MongoClient
client = MongoClient('mongodb+srv://text:sparta@cluster0.tvnfddc.mongodb.net/Cluster0?retryWrites=true&w=majority')
db = client.dbsparta

 

# 저장 - 예시
doc = {'name':'bobby','age':21}
db.users.insert_one(doc)

# 한 개 찾기 - 예시
user = db.users.find_one({'name':'bobby'})

# 여러개 찾기 - 예시 ( _id 값은 제외하고 출력)
all_users = list(db.users.find({},{'_id':False}))

# 바꾸기 - 예시
db.users.update_one({'name':'bobby'},{'$set':{'age':19}})

# 지우기 - 예시
db.users.delete_one({'name':'bobby'})

 

첫단계 데이터 쌓기

from pymongo import MongoClient
client = MongoClient('mongodb+srv://text:sparta@cluster0.tvnfddc.mongodb.net/Cluster0?retryWrites=true&w=majority')
db = client.dbsparta

doc = {
    'name' : 'bob',
    'age' : 27
}

db.users.insert_one(doc)

유저 리스트 부르기

from pymongo import MongoClient
client = MongoClient('mongodb+srv://text:sparta@cluster0.tvnfddc.mongodb.net/Cluster0?retryWrites=true&w=majority')
db = client.dbsparta

all_users = list(db.users.find({},{'_id':False}))

for user in all_users:
    print(user)
