from pymongo import MongoClient

#一、連接
client=MongoClient('mongodb://root:123@localhost:27017/')
# client = MongoClient('localhost', 27017)

#二、use 數據庫
db=client['db2'] #等同於：client.db1

#三、查看庫下全部的集合
print(db.collection_names(include_system_collections=False))

#四、建立集合
table_user=db['userinfo'] #等同於：db.user

#五、插入文檔
import datetime
user0={
    "_id":1,
    "name":"egon",
    "birth":datetime.datetime.now(),
    "age":10,
    'hobbies':['music','read','dancing'],
    'addr':{
        'country':'China',
        'city':'BJ'
    }
}

user1={
    "_id":2,
    "name":"alex",
    "birth":datetime.datetime.now(),
    "age":10,
    'hobbies':['music','read','dancing'],
    'addr':{
        'country':'China',
        'city':'weifang'
    }
}
# res=table_user.insert_many([user0,user1]).inserted_ids
# print(res)
# print(table_user.count())

#六、查找

# from pprint import pprint#格式化細
# pprint(table_user.find_one())
# for item in table_user.find():
#     pprint(item)

# print(table_user.find_one({"_id":{"$gte":1},"name":'egon'}))

#七、更新
table_user.update({'_id':1},{'name':'EGON'})

#八、傳入新的文檔替換舊的文檔
table_user.save(
    {
        "_id":2,
        "name":'egon_xxx'
    }
)
