Python connection Mongo

Connecting the MongoDB database with the Pymongo module should be used like this:

Mongoclient

Mongoclient(hostport=Port)

DB = conn [DB] #连接指定数据库

DB [Col]. Find_one(x)

Db.spgoods.find_one (x)

DB [Col]. Update({"_id"spinfo["_id"]  }True)

Db[Col]. Update({"_id": Spinfo["_id"]},{"$set":Spinfo},True)

. db[table]. Insert(spinfo)

DB [table]. Find()

You can also write a class pattern

classNoSQL:
    def__init__( Self, host, port, DB):#主机地址, port, database name
         Self. conn= Mongoclient(Host= HostPort=Port)
         Self. db=  Self. conn[Db]#连接指定数据库

def   ( self , X)  :  

  =  [ "Spgoods" . Find_one ( x) 
  

    Spdata

defUpdatespgood( Self, Spinfo):
     Self. db["Spgoods"]. Update({"_id": Spinfo["_id"]}, Spinfo,True)
    True

NoSQL(' localhost '27017'goods ')

Then connect to the database layer to write this

defGetspinfo(Item,value,depart,comp):
    Result= Pnosql.conn.getthespgood({Item: Value"Depart":Depart,"Comp": Comp})

getting this form of data requires a loop output

defGetspgoods( Self, table):
    Spdata=  Self. DB[Table]. Find()
    returnSpdata
