$match aggregate in mongoose - http

Question

I am using $match to find a userid that is reference in my schema. When I pass in http://localhost:3001/api/orders/5d6f1611d3bcd442bc273211/2018-02-01/2019-09-01 I get the following:
5d6f1611d3bcd442bc273211
[0] 2018-02-01
[0] 2019-09-01
[0] ReferenceError: $match is not defined
Here is my code:
getOrderTotal: function (req, res) {
const userID = req.params.userid;
const firstDate = req.params.firstdate;
const secondDate = req.params.seconddate;
console.log(userID);
console.log(firstDate);
console.log(secondDate);
Order
.aggregate([{ $match: { 'user': userID } }])
.find({ "created_at": { "$gte": firstDate, "$lt": secondDate } })
.then(dbModel => res.json(dbModel))
.catch(err => res.status(422).json(err));
}
When I remove the line containing $match, I get the expected results. When I leave it in, I get an empty array.

Answer 1

convert userId to ObjectID
var mongoose = require('mongoose');
var id = mongoose.Types.ObjectId(userID);
Then use id in your $match aggregation
or
.aggregate([{ $match: { 'user': mongoose.Types.ObjectId(userID) } }])

Answer 2

You can use $find and $match at one time using expr.
const userID = req.params.userid;
const firstDate = req.params.firstdate;
const secondDate = req.params.seconddate;
console.log(userID);
console.log(firstDate);
console.log(secondDate);
Order.find({
"$expr": {
"$and": [
{ "$eq": ["$user", userID] },
{ "$gte": [{ "$created_at": firstDate }]},
{ "$lt": [{ "$created_at": secondDate }]}
]
}
}).exec((err , found)=>{
});

I am guessing this is what you want to achieve
Find document that has user matching userId
and has date greater than or equal to firstDate and less than secondDate
If you insist on using the aggregate pipeline plus $match operator, you must then be aware of the following
Note:
The documents returned are plain javascript objects, not mongoose documents (since any shape of document can be returned). More info here: https://mongoosejs.com/docs/api/aggregate.html
Example:
getOrderByDate: async (req, res) => {
// Get the parameter data from req.params
let { user, firstDate, secondDate } = req.params;
// Convert the user data type to mongoose ObjectId
user = mongoose.Types.ObjectId(user);
// Convert both firstDate and SecondDate to date
firstDate = new Date(firstDate);
firstDate.setHours(0, 0, 0, 0);
secondDate = new Date(secondDate);
secondDate.setHours(23, 59, 59, 999);
// See the output in your console if you will...
console.log({ user, firstDate, secondDate });
// Using async (you can still use promises if you will)
try {
const matchedDocuments = await OrderDocument.aggregate([{ $match: { user: user } }]);
// Filter returned document
const result = matchedDocuments.filter((docs) => {
if (docs.created_at >= firstDate && docs.created_at < secondDate) {
return true;
}
});
res.status(200).json({ result });
} catch (error) {
res.status(500).json({ error, message: 'Something went wrong' });
}
}
