任何人都可以帮助我使用 $lookup 加入 MongoDB 来获取日期在日期“X”和日期“Y”之间且 Chef_id 为“P”的所有订单。 “日期”部分有问题，没有提供日期数据。但是当我在单个查找查询中使用它时，它工作正常并提供日期之间的数据。但当我使用 $lookup 进行连接时，它没有提供数据。 这是我的查询
Order.aggregate([{
"$lookup": {
"localField": "user_id",
"from": "users",
"foreignField": "_id",
"as": "order_data"
}
},
{
"$match": {
"$and": [
{ "chef_id": mongoose.Types.ObjectId(req.body.chef_id) },
{ "booking_datetime": { $gte: start_time,
$lte: end_time } }
]
}
}
], function(err, gettt) {
if (err) {
res.json({ 'message': "Error", 'status': false, 'data': err });
return false;
} else {
if (gettt.length != 0) {
res.json({ 'message': "Orders Data", 'status': true, 'data': gettt });
} else {
res.json({ 'message': "No Orders for this date", 'status': false, 'data': gettt });
}
}
});
谁能帮帮我。

最佳答案
你的语法看起来不错。我仍然怀疑存在某些数据类型不匹配或格式错误。我有一个与日期范围匹配的类似聚合，并且我使用 new Date() 将字符串转换为日期。
if (typeof dateBeginning === "string" && dateBeginning != "" && typeof dateEnding === "string" && dateEnding != "" && dateEnding >= dateBeginning) {
query.date = { $gte: new Date(dateBeginning), $lte: new Date(dateEnding) };
}
这是一个SO question: Date query with ISODate in mongodb doesn't seem to work 就这样解决了。
此外，Veeram 是正确的；你应该把你的$match放在第一位。这样，MongoDb 将使用可用的匹配字段上的任何索引。
关于node.js - Mongodb Node.js $lookup 带日期和 $match，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48565790/
