How to query date from mongodb using graphql? - mongodb

Question

I am trying to find documents by DateTime.
I have the following sample of mongo document:
{
"_id" : ObjectId("5df8ea55ac02282c15917e46"),
"title" : "Bán gấp căn 01 DT 62m2 căn góc, giá 1,05 tỷ. LH C Nga 0979441985",
"address" : "La Khê - Hà Đông",
"avatar" : "https://file4.batdongsan.com.vn/crop/200x200/2019/12/07/20191207173723-31f3_wm.jpg",
"price" : "1.05 Tỷ",
"lat" : 20.9719924926758,
"lon" : 105.756340026855,
"id" : 15504225,
"area" : "62 m²",
"cat" : "Bán căn hộ chung cư",
"date" : "17/12/2019",
"room" : 2,
"DateTime" : ISODate("2019-12-17T22:00:36.136+08:00")
}
I have defined a schema:
const sellType = new GraphQLObjectType({
name:'Sell',
fields: () => ({
_id:{type:GraphQLString},
id:{type:GraphQLString},
title:{type:GraphQLString},
address:{type:GraphQLString},
avatar:{type:GraphQLString},
price:{type:GraphQLString},
DateTime:{type:GraphQLDateTime}
})
})
I have also defined the root query:
const RootQuery = new GraphQLObjectType({
name:'RootQueryType',
fields: {
property_for_sell_by_datetime:{
type: sellType,
args:{DateTime:{type:GraphQLDateTime}},
resolve(parent, args){
return sell.find({DateTime:new Date(args.DateTime)})
}
}
}
})
But I don't know why I cannot find any document using:
{
property_for_sell_by_datetime(DateTime:"2019-12-17T14:00:36.136Z"){
_id
DateTime
}
}
Edit:
I tired to use findOne. It works. But find is not working
Edit2:
I need to define type as GraphQLList

Answer 1

to use find instead of findOne, I need to define the type as GraphQLList
