I'm trying to reach different select's from another select with MongoDB database with mongoose to redirect to Emberjs front-end.
If the text above it's not clear, look at the schema of the database:
// I already get the exam content given an id
Exam:{
...
cllections:[{
question: Object(Id)
}]
...
}
and in the question schema it's:
question:{
...
questions: String, // I want to get this given an Id exam
value: Number // and this
...
}
I tried to get it getting the objects id of the collections and then make a for to extract each question, and save the returned values into a json variable like this:
Test.findById(id, 'collections', function(err, collections){
if(err)
{
res.send(err);
}
var result ={}; //json variable for the response
// the for it's with the number of objectId's that had been found
for(var i = 0; i < collections.collections.length; i++)
{
// Send the request's to the database
QuestionGroup.findById(collections.collections[i].id).exec(function(err, questiongroup)
{
if(err)
{
res.send(err);
}
// save the results in the json
result.questiongroup = questiongroup;
});
// it return's {}
console.log(result);
}
// also return {}
console.log(result);
res.json({result: result});
});
It's there a way to save the requests into a variable and return it like a json to the front end?
