Mongoose findById nullを返す

Question

モデルに関する情報を調整しようとしています。私はこれをmodel.find（{_ id： "id"、function（err、foundModel）{}）を使ってやっています。関数。私もfindByIdとfindByIdAndUpdateで試してみましたが、うまくいけません。

問題は、find関数が結果を返さないことと、エラーを返さないことです。ここで

はモデルです：

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; 

そしてここではコードです：

var express = require("express"); 
var router = express.Router({mergeParams: true}); 
var passport = require("passport"); 
var User = require("../models/user"); 
var Race = require("../models/race"); 
var Result = require("../models/result"); 
var Rider = require("../models/rider"); 
var mongoose = require("mongoose"); 

var pointsArray = [ 
    250, 200, 175, 150, 130, 115, 100, 95, 90, 85, 80, 75, 70, 65, 60, 55, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5 
    ]; 

router.get("/:id/finalize", function(req, res){ 
     Result.findById(req.params.id, function(err, foundResult){ 
      if(err){ 
       console.log("Something went wrong with finding the result to finalize"); 
      } else { 
       console.log("This is the result I found: " + foundResult); 
       var riders = []; 
       riders = foundResult.riders; 
       console.log(riders); 

       var j = 0; 

       riders.forEach(function(rider){ 
        Rider.find({_id: rider}, function(err, foundRider){ 
         if(err){ 
          console.log("program tried to look up rider for the forEach loop finalizing the results, but could not find"); 
         } else { 
          console.log(rider); 
          j = j + 1; 
          console.log("This is the " + j + "th rider I found: " + foundRider); 
          foundRider.points = foundRider.points + pointsArray[j]; 
          console.log("done"); 
         } 
        }); 
       }); 
       res.redirect("/results/admin"); 
      } 
     }); 
    }); 

これは、私は少し周りを微調整した後に取得する出力です：

私はコンソールのロギングは、IDがそこにあることとオブジェクト/配列がどのようにネストされているかを自分自身に証明するだけです。

Rider.find({_id: rider}, function(err, foundRider){がnullを返すという問題があります。

誰でも私にこれを手伝うことができますか？もっと情報が必要な場合はお知らせください。

ベスト、

OMG。私はついに何も働いていないことを知りました。私はサーバーを起動するたびに播種しています。私のライダーは常に完全に新しいIDで取り除かれ、再作成されます。結果に保存されている古いものは決して動作しません。
