몽구스 findById 반환 null

Question

모델에 대한 정보를 조정하려고합니다. 나는 model.find ({_ id : "id", function (err, foundModel) {}); 기능. 나 또한 findById 및 findByIdAndUpdate로 시도했지만 모두 작동하지 않는 것 같습니다.

문제는 찾기 기능이 결과를 반환하지 않으며 오류가 발생하지 않는다는 것입니다. 여기

는 모델 :

var mongoose = require("mongoose"); 

//CREATE THE SCHEMA 
var riderSchema = new mongoose.Schema({ 
    firstName: String, 
    lastName: String, 
    price: Number, 
    points: {type: Number, default: 0}, 
    nationality: String, 
    team: String, 
    photo: String, 
}); 

//CREATE THE MODEL 
var Rider = mongoose.model("Rider", riderSchema); 

//EXPORT THE MODEL 
module.exports = Rider; 

그리고 여기에 코드입니다 :

이 내가 조금 주위를 조정 한 후에 얻을 출력은 콘솔 로깅은 ID가 있다는 것과 객체/배열이 중첩되어 있음을 증명합니다.

문제는 Rider.find({_id: rider}, function(err, foundRider){이 null을 반환한다는 것입니다.

누구나 도움이 될 수 있습니까? 더 많은 정보가 필요하면 알려주십시오.

OMG. 나는 마침내 아무것도 작동하는 이유를 알게되었습니다. 내 서버를 시작할 때마다 시드를하고 있습니다. 모든 라이더는 끊임없이 완전히 새로운 ID로 제거하고 다시 만듭니다. 결과에 저장되는 오래된 것들은 결코 작동하지 않습니다.
