MongoDB एक से कई संबंधों में बच्चों के आइटम दिखाएं

निम्नलिखित पाइपलाइन आपको विचार देना चाहिए

db.getCollection('yourCollection').aggregate(
    {
        $unwind: {
            path: "$dates",
            includeArrayIndex: "idx"
        }
    },
    {
        $project: {
            _id: 0,
            dates: 1,
            numbers: { $arrayElemAt: ["$numbers", "$idx"] },
            goals: { $arrayElemAt: ["$goals", "$idx"] },
            durations: { $arrayElemAt: ["$durations", "$idx"] }
        }
    }
)

जो आपके नमूने के लिए निम्न आउटपुट उत्पन्न करता है

/* 1 */
{
    "dates" : NumberLong(1399518702000),
    "numbers" : "5982",
    "goals" : "1",
    "durations" : "78"
}

/* 2 */
