I work with nodejs/express/mongoose/angularjs. I'd like to update a collection named Lists which has several properties, one of which is an array of items. In the following code, I'm pushing a new task items in the items array. Everything works fine, however the update function does not sends back the updated collection, then I must perform another query on the database. Is there a more efficient way to do this ?
The nodejs/express code :
exports.addTaskToList = function(req, res) {
var listId = req.params.Id;
var taskId = req.params.TaskId;
Lists.update({_id: listId}, {$push: {items: taskId}}, {safe:true, upsert: true}, function(err, result){
if(err) {
console.log('Error updating todo list. ' + err);
}
else{
console.log(result + ' todo list entry updated - New task added');
Lists.findById(listId).populate('items').exec(function (err, updatedEntry) {
if (err) {
console.log('Unable to retrieve todo list entry.');
}
res.send(JSON.stringify(updatedEntry));
});
}
});
};
Furthermore, the array items is an array of ObjectIds. Those items are in a separate schema so in a separate collection. Is it possible to push the whole object and not only its _id so that there is not another collection created ?
