I'm currently in the process of working with Express and MongoDB, where I have data items structured like the following:
{
"_id": {
"$oid": "63107332e573393f34cb4fc6"
},
"title": "Eiffel tower",
"attractionType": [
{"$oid": "63035678df60496a551a8138"},
{"$oid": "63035678df60496a551a813d"},
{"$oid": "63035678df60496a551a8142"},
{"$oid": "63035678df60496a551a813e"}],
}
{
"_id": {
"$oid": "63107332e585673f54hj444"
},
"title": "Taj Mahal",
"attractionType": [
{"$oid": "63035678df60496ao6567p90"},
{"$oid": "63035678567h496a551a66gr"},
{"$oid": "63035678df60496a551a8138"},
{"$oid": "63035678df60496a551a813d"}],
}
My current challenge involves filtering these items based on attractionType. When sending attraction types as queries to Rest API, the format is like this:
http://localhost:8000/app/heritages?attractions=63035678df60496a551a813
The above query works for a single value of attractionType, but I would like to understand how to handle multiple attraction types like this:
http://localhost:8000/app/heritages?attractions=63035678df6d6a51a8136,6303568df6049a551a8137
Below is my code snippet for handling one attraction type, I need help on extending it to handle more than one filter:
var { attractions } = req.query;
var lang = req.lang;
var conditions = { lang: lang };
if (attractions && attractions.length > 0) {
conditions.attractionType = attractions;
}
try {
Heritage.find()
.where(conditions)
.populate("provinceId attractionType")
.sort(sortItem)
.exec((err, doc) => {
if (err) {
return res.status(500).json({ message: "server Error", err });
}
return res.status(200).json({ message: "seccess", lists: doc });
});
} catch (e) {
return res.status(500).json({ message: "server Error" });
}
};
