I am developing a bus ticket booking app in node.js. I want to design a location schema in such a way that whenever user enters a from-location like: philadelphia then in the to-location dropdown all the other location should appear like new jersy or newyork except philadelphia.
const locationSchema = new mongoose.Schema({
location:{
name: {
type: String,
required: true,
subLocation: [String],
//Should I add type = 1
}
}
});
You can use MongoDB $ne (not equal to) method
db.collection.find({
"location.name": {
$ne: req.body.fromLocation //change variable name according to requirement
}
})
Now you can set this data in the other dropdown
