MongoDB: How to insert complex schema - json

Question

I'm building a "Test" system. each test has some questions.
Each question has answers.
I'm getting a JSON to create the question from another server as:
{
requestType: 'CreateNewQuestion',
questionId: 17447,
subject: "Math",
subsubject: "Heshbon",
questionText: "1+4 Equels?",
answers: [{text : "2",rightAnswer : false},
{text : "35",rightAnswer : false},
{text : "5",rightAnswer : true},
{text : "9",rightAnswer : false}]
}
I built 2 Schemas:
module.exports = mongoose.model('Answer' ,
{
text: String,
rightAnswer: Boolean
}
);
And
module.exports = mongoose.model('Question' ,
{
questionId: Number,
subject: String,
subsubject: String,
questionText: String,
answerTimeAvg: Number,
fastestAnswer: Number,
answers: [{ type : mongoose.Types.ObjectId, ref: 'Answer' }]
}
);
I made a function that get the JSON and try to save it like:
var QuestionSchema = require('./schemas/question');
var AnswerSchema = require('./schemas/answer');
CreateNewQuestion: function (message) {
var information = {
questionId: message.questionId,
subject: message.subject,
subsubject: message.subsubject,
}
//Save Question
var record = new QuestionSchema(information);
record.save(function (err) {});
}
How can I create the Answers object and populate them into the question?
I tried couple of things but keep getting error,
What is the proper way?
I tried to read in "mongoosejs.com/docs" but the site is down :(

Answer 1

I needed to change the model to:
module.exports = mongoose.model('Question' ,
{
subject: String,
subsubject: String,
questionText: String,
answerTimeAvg: Number,
fastestAnswer: Number,
answers: [{ type : mongoose.Schema.Types.ObjectId, ref: 'Answer' }]
} );
And save the answers first, and than use the IDs:
CreateNewQuestion: function (message) {
////////////////////////
// Saving the answers //
////////////////////////
var answers = message.answers;
var answers_ids = [];
for(var i in answers) {
var answer = new AnswerSchema(answers[i]);
answer.save();
answers_ids.push(answer._id);
}
/////////////////////////
// Saving the question //
/////////////////////////
var information = {
subject: message.subject,
subsubject: message.subsubject,
questionText: message.questionText,
answerTimeAvg: 0,
fastestAnswer: 0,
answers: answers_ids
}
var record = new QuestionSchema(information);
record.save(function (err) {
if (err) {
console.log("Bad = " + err);
var result = "bad";
message.sendReplay({result: result});
}
else {
var result = "AllGood";
message.sendReplay({result: result});
}
});
},
