} 

Ich habe storeCode, offer name & coupen .So Ich brauche die status des entsprechenden aktualisieren Objekt auf alloted.

Für Ex: Wenn storeCode = LULUMALL, name = Angebot1 & coupen = adssd, also muss ich die status des entsprechenden Objekts allotted .Nach Update aktualisieren, The Collection sollte so sein. Coupen Sammlung Nach einem Update

{ 
    "_id": ObjectId("571501b7cbd85fe5ce5a749c"), 
    "storeCode": "LULUMALL", 
    "offers": [{ 
      "name": "offer1", 
      "coupens": [ 
       { "coupen": "adssd", "status": "allotted" }, 
       { "coupen": "sdsafa", "status": "open" }, 
       { "coupen": "wewerw", "status": "open" },

Answer 1

ich diese Daten in einer neuen Variablen nur kopiert und den Wert von status Feld allotted basierend ändern auf die Bedingung.

Hier Shopdaten sind die Eingangsdaten

var updateData = shopData; 

updateData die Kopie shopData ist.

updateCoupen.offers[index].coupens[randomNo].status = 'allotted'; 

index und randomNo wird unter der Bedingung erhalten basiert.

Coupen.update({ "storeCode": store }, { $set: { 'offers': updateData.offers } }, function(err, numAffected) { 
    console.log('numAffected', numAffected); 

}) 

Code Complete

var store = 'LULUMALL'; 
var name = 'offer1'; 
var coupen = 'adssd'; 
var shopData = { 
    "_id": ObjectId("571501b7cbd85fe5ce5a749c"),

for (var i = 0; i < shopData.offers.length; i++) {

       coupen.push(shopData.offers[i].coupens[j]); 
      } 
     } 
     console.log('Available Coupens', coupen); 
     var randomNo = Math.floor(Math.random() * coupen.length); 
     var rand = coupen[randomNo]; 
     var updateCoupen = shopData;
