I have the below code to insert data to mongo db,
var obj=[];
ThirdNavigation.find(searchApp).exec(function(err, app) {
if (err) return done(err);
app.forEach(function(navi){
if(typeof navi.variants == "undefined"){
ApplicationInventory.findOrCreate({id :navi.id},navi).exec(function(e,update){
if(e) console.log(e);
var query = {
productId: navi.id,
appId: navi.appId,
childId: navi.childId,
name: navi.name,
price: navi.price,
quantity: navi.quantity
}
PriceAndVariants.findOrCreate({productId : navi.id},query).exec(function(err,variants){
if(err) console.log(err);
if(variants != ""){
update.variant = variants[0];
obj.push(update);
}
else{
obj.push(update);
}
})
})
}
else{
var jData = JSON.parse(navi.variants);
for(var i=0; i< jData.length; i++){
navi.price = jData[i].price;
navi.quantity = jData[i].quantity;
navi.sku = jData[i].sku;
navi.discount = jData[i].discount;
ApplicationInventory.findOrCreate({id :navi.id},navi).exec(function(e,update){
if(e) console.log(e);
var query = {
productId: navi.id,
appId: navi.appId,
childId: navi.childId,
name: navi.name,
price: navi.price,
quantity: navi.quantity
}
PriceAndVariants.findOrCreate({productId : navi.id},query).exec(function(err,variants){
if(err) console.log(err);
// console.log(update);
if(variants != ""){
update.variant = variants[0];
obj.push(update);
}
else{
obj.push(update);
}
console.log(obj);
})
})
}
}
})
console.log(obj);
res.send(obj);
});
But the obj is becoming null and I receive a null array from the frontend. But when I print the obj inside the forEach the data is printing perfectly.I can't find the error.
