使用node.js在mongoDB中处理文档

Question

i have following code of node.js where by it connects to mongoDB and i would like to insert the message displayed at node.js console in to collection called "mytable". The problem i am facing is it is successfully connecting to mongoDB and it also inserts the message which is displaying at node.js console but instead of insterting as one full document it is inserting as characters. why it is so happening? pls help

var mongo = require("mongodb");
var dbhost = "127.0.0.1";
var dbport = mongo.Connection.DEFAULT_PORT;
var db = new mongo.Db("mydb", new mongo.Server(dbhost, dbport, {}), {safe: true});
db.open(function(error){
        status = ("db connected at" + dbhost + " : " + dbport);
        console.log(status);

        db.collection("mytable",function (error,collection){

        collection.insert(status, function(error){

            if (error){
                console.log("Error : ", error.message);
            } else {
                console.log("Inserted in to database");
                } 

            });
        }); 


});

my node console display output as

db connected at127.0.0.1 : 27017
Inserted in to database

while checking 'mytable' mongo shell with command

db.mytable.find.forEach(printjson)

it is showing following output

{

"_id" : objectId("5207741d193770459f068317"),
"0" : "d",
"1" : "b",
"3" : " ",
"4" : "c",
"5" : "o",
"6" : "n",
"7" : "e",
"8" : "c",
"9" : "t",
"10" : "e",

"28" : "7",
"29" : "0",
"30" : "1",
"31" : "7"

}

Please help i want only one entry ie 'db connected at 127.0.0.1 : 27017' to be instertd in to mytable as single document.

Mongo treats the string you're trying to insert as a BSON document (and hence an object) and iterates it's properties treating them as document fields.

Try inserting an actual object with the value you want as property:

collection.insert({status: status}, function(error){

        if (error){
            console.log("Error : ", error.message);
        } else {
            console.log("Inserted in to database");
            } 

        });
    });
