MongoDB: I want to store array object in collection

Question

I get array object from front side, and want to save it in collection using NodeJS, Mongodb.

My object is:

routerData={"User-Name":
    {"type":"string","value":["\u0000\u0000\u0000\u0000"]},
"NAS-IP-Address":
    {"type":"ipaddr","value":["10.1.0.1"]}
},

My collection schema is:

var model = new Schema({
routerData:{
    "User-Name": {
        "type": String,
        "value": []
    },
    "NAS-IP-Address": {
        "type": String,
        "value": []
    },

},
});

I am trying with this code:

var obj = new objModel(req.body);
obj.routerData = req.body.routerData;
obj.save(function (err, result) {

});

i am getting this error:

"message": "Cast to Object failed for value \"{\"User-Name\":{\"type\":\"string\",\

So what is the problem you are experiencing? What did you try? — Antonio Narkevich, Feb 11 '17 at 06:51

If you want to have a property named 'type' in your schema you should specify it like this 'type': {type: String}.

Also your value arrays should have type: "value": [String]

Here is a working example.

'use strict';

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/test');
var Schema = mongoose.Schema;

var schema = new Schema({
 routerData: {
  'User-Name': {
   'type': {type: String},
   'value': [String]
  },
  'NAS-IP-Address': {
   'type': {type: String},
   'value': [String]
  },

 },
});

var RouterData = mongoose.model('RouterData', schema);

var routerData = {
 'User-Name': {'type': 'string', 'value': ['\u0000\u0000\u0000\u0000']},
 'NAS-IP-Address': {'type': 'ipaddr', 'value': ['10.1.0.1']}
};

var data = new RouterData({routerData: routerData});
data.save();

i am in trouble with this type data: var routerData = { "Attr-26.14559.10":{"type":"octets","value":["0x00000002"]} } – Hardik Mandankaa Feb 11 '17 at 07:42
@HardikMandankaa what is the issue? – Antonio Narkevich Feb 11 '17 at 07:54
can you try to replace "routerData" value and test? – Hardik Mandankaa Feb 11 '17 at 08:02
@HardikMandankaa did you extend the schema and added "Attr-24.14559.10" field to it? – Antonio Narkevich Feb 11 '17 at 08:07
yes. i added in schema. it is store in collection in this format: ""Attr-26" : { "14559" : { "10" : { "type" : "octets", "value" : [ "0x00000002" ] } } }," I need to it store like other value – Hardik Mandankaa Feb 11 '17 at 08:14
@HardikMandankaa please check out this thread http://stackoverflow.com/questions/12397118/mongodb-dot-in-key-name You might need to change the structure and say store parameters in array and have something like this routerData: [{parameterName: ''Attr-24.14559.10", type: .., value: ...}, ...] – Antonio Narkevich Feb 11 '17 at 08:36
