Question

I have given my output for this how can I make schema.any one give example for this I have added my schema also
My output code:
$scope.countries = [{
"name": "India",
"states": [{
"name": "Maharashtra",
"cities": [{
"name": "Pune"
}, {
"name": "Mumbai"
}, {
"name": "Nagpur"
}, {
"name": "Akola"
}]
}, {
"name": "Madhya Pradesh",
"cities": [{
"name": "Indore"
}, {
"name": "Bhopal"
}, {
"name": "Jabalpur"
}]
}, {
"name": "Rajasthan",
"cities": [{
"name": "Jaipur"
}, {
"name": "Ajmer"
}, {
"name": "Jodhpur"
}]
}]
}, {
"name": "USA",
"states": [{
"name": "Alabama",
"cities": [{
"name": "Montgomery"
}, {
"name": "Birmingham"
}]
}, {
"name": "California",
"cities": [{
"name": "Sacramento"
}, {
"name": "Fremont"
}]
}, {
"name": "Illinois",
"cities": [{
"name": "Springfield"
}, {
"name": "Chicago"
}]
}]
}, {
"name": "Australia",
"states": [{
"name": "NewSouthWales",
"cities": [{
"name": "Sydney"
}]
}, {
"name": "Victoria",
"cities": [{
"name": "Melbourne"
}]
}]
}];
This is my routes:
app.route('/address')
.get(address.list)
.post(address.create);
Controller code:
/**
* Create a address
*/
exports.create = function(req, res) {
var address = new Address(req.body);
address.user = req.user;
address.save(function(err) {
if (err) {
return res.status(400).send({
message: errorHandler.getErrorMessage(err)
});
} else {
res.json(address);
}
});
};
Schema code :
'use strict';
/**
* Module dependencies.
*/
var mongoose = require('mongoose'),
Schema = mongoose.Schema;
var citySchema = {
name: {type:String, required: false}
};
citySchema = 'new Schema('+ citySchema +',{_id:false})';
var stateSchema = {
name: {type:String, required: false},
cities: [citySchema], default:[]
};
stateSchema = 'new Schema('+stateSchema +',{_id:false})';
var countrySchema = {
name: {type:String, required: false},
states: [stateSchema], default:[]
};
// dbObj is mongoose connection object
var collectionObj = dbObj.model('countries', countrySchema);
i have updated my routes and controller schema .how can i change to inser that object pls give some suggestion ?

Answer 1

Please try with following schema :-
var citySchema = {
name: {type:String, required: false}
};
citySchema = 'new Schema('+ citySchema +',{_id:false})';
var stateSchema = {
name: {type:String, required: false},
cities: [citySchema], default:[]
};
stateSchema = 'new Schema('+stateSchema +',{_id:false})';
var countrySchema = {
name: {type:String, required: false},
states: [stateSchema], default:[]
};
// dbObj is mongoose connection object
var collectionObj = dbObj.model('countries', countrySchema);
Now if you want to insert any single country data into db please go through with following procedure-
// Let us assume that we need to insert following data first
var data = {
"name": "India",
"states": [{
"name": "Maharashtra",
"cities": [{
"name": "Pune"
}, {
"name": "Mumbai"
}, {
"name": "Nagpur"
}, {
"name": "Akola"
}]
}, {
"name": "Madhya Pradesh",
"cities": [{
"name": "Indore"
}, {
"name": "Bhopal"
}, {
"name": "Jabalpur"
}]
}, {
"name": "Rajasthan",
"cities": [{
"name": "Jaipur"
}, {
"name": "Ajmer"
}, {
"name": "Jodhpur"
}]
}]
};
// add country
var insertObj = {
"name": "India",
"states": []
}
countryModel.create(insertObj, function (err, job) {
cb(err, job);
});
// add states
var states = [{
"name": "Maharashtra",
"cities": []
}, {
"name": "Madhya Pradesh",
"cities": []
}, {
"name": "Rajasthan",
"cities": []
}];
var stateCond = {"name": "India"};
var stateUpdate = {$push: {states: states}};
var stateOpts = {};
countryModel.findOneAndUpdate(stateCond, stateUpdate, stateOpts, function (err, resp) {
cb(err, resp);
});
// Now if you want to add "Maharastra" Cities
var cities = [{
"name": "Pune"
}, {
"name": "Mumbai"
}, {
"name": "Nagpur"
}, {
"name": "Akola"
}]
var cityCond = {"name": "India", "states.name": "Maharashtra"};
var cityUpdate = {$push: {cities: cities}};
var cityOpts = {};
countryModel.findOneAndUpdate(cityCond, cityUpdate, cityOpts, function (err, resp) {
cb(err, resp);
});
// Now same insertion query need to be run for "Madhya Pradesh" and "Rajasthan"
Thanks
