Get data from JSON using query parameters - mongodb

Question

I have to make an API whose endpoint will be like day=1&time=1000 and by using these query parameters I have to write a mongo query, JSON will be like
"_id" : ObjectId("62257ddd76b35400010e7015"),
"applyOffersOn" : [
{
"day" : 1,
"startTime" : NumberLong("1646625639561"),
"endTime" : NumberLong("1646631039561"),
"startTimeFormat" : NumberLong(930),
"endTimeFormat" : NumberLong(1100)
},
{
"day" : 2,
"startTime" : NumberLong("1646625639561"),
"endTime" : NumberLong("1646631039561"),
"startTimeFormat" : NumberLong(930),
"endTimeFormat" : NumberLong(1100)
},
{
"day" : 3,
"startTime" : NumberLong("1646625639561"),
"endTime" : NumberLong("1646631039561"),
"startTimeFormat" : NumberLong(1930),
"endTimeFormat" : NumberLong(2100)
}
],
}```
the query should be like I have to first check for a particular object using objectId then finding the object, check for the day is present as 1 and then check for the time that it will be between
startTimeFormat and endTimeFormat if all these conditions satisfy then return the whole object
I have written the query but it either works for the day or for a time but it should work like it check for both condition

Answer 1

I think this will help ,
##elemMatch - it will loop you through all elements of array.
const answer = <your model schema>.findById(req.params.id).find({applyOffersOn:{$elemMatch:{day:<your day from query> } }}).find({applyOffersOn:{$elemMatch : {startTimeFormat: {$lte:<your time from query> },endTimeFormat:{$gte:<your time from query>} }}})
