Saving multiple field array in mongodb using mongoose - arrays

Question

//Here is model
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var ObjectId = Schema.ObjectId;
// Task schema
var taskSchema = mongoose.Schema({
tasktype : {type: String},
createdon : {type: Date, default: Date.now},
createdby : {type: Schema.Types.ObjectId,ref: 'User'},
visitedby : [{type: Schema.Types.ObjectId,ref: 'User'}],
taskinfo : [{ isactive:Boolean, taskobject:String, taskdetails:String, iscompleted:Boolean}]
});
module.exports = mongoose.model('Task', taskSchema);
// route
var Task = require ('../models/task');
var User = require ('../models/user');
var config = require ('../../config');
module.exports = function(app, express) {
var api = express.Router();
api.post('/tasks', function (req, res) {
var task = new Task({
// ...
tasktype : req.body.tasktype,
taskinfo : req.body.taskinfo,
});
task.save(function(err){
if(err){
res.send(err);
return;
}
res.json({message:'Task has been created'})
});
return api
}
While all other fields getting saved but the one with array with multiple fields always return blank like "taskinfo : [ ] "
The post method is REST API to post a task into mongoose database, for array with single field everything working fine but array with multiple field is not getting saved, someone please help me here.
Basic help will be fine, just please teach me how to save "multiple field array".
Mongoose doesnot always require subdocument structure and this can be achieved by the above model, please dont advice to use subdocument structure, I want to learn this.
Thank You.

I think if taskinfo has a multiple values and you want to save it as embedded document inside task document. You should have different document of task info. So,you can save like that
var TaskInfoSchema = require("taskInfo.js").TaskInfoSchema
var taskSchema = mongoose.Schema({
tasktype : {type: String},
createdon : {type: Date, default: Date.now},
createdby : {type: Schema.Types.ObjectId,ref: 'User'},
visitedby : [{type: Schema.Types.ObjectId,ref: 'User'}],
taskinfo : [TaskInfoSchema]
});
module.exports = mongoose.model('Task', taskSchema);
And now you will have different document as task info like
var taskInfo = mongoose.Schema({
isactive:{type:Boolean},
taskobject:{type:String},
taskdetails:{type:String},
iscompleted:{type:Boolean}
});
var TaskInfo = mongoose.model('TaskInfo', taskSchema);
module.exports.TaskInfo = TaskInfo
module.exports.TaskInfoSchema = taskSchema
When you will save task document,
Var TaskInfo = new TaskInfo({
isactive:true,
taskobject:"",
taskdetails:"",
iscompleted:true
})
var task = {};
task.tasktype = req.body.tasktype;
you can push it
task.taskinfo = [];
for (var i = 0; i < req.body.taskInfo.length; i++) {
var taskInfo = new TaskInfo(req.body.taskInfo[i]);
task.taskinfo.push(taskInfo);
}
Then you will save task document
var taskObj = new Task(task);
taskObj.save(function (err) {
if (err) {
res.send(err);
return;
}
res.json({
message: 'Task has been created'
})
});
});
