Question

我正在尝试创建一个锻炼管理应用程序，该应用程序允许教练（userType = true）为用户创建锻炼。不幸的是，我不确定如何格式化mongodb模式以接收大量练习。我的想法是创建一个JSON对象数组，然后将其推入数据库以稍后显示给用户。问题是我不知道如何正确创建一个可以正确解析数据的表单。我决定创建几种形式，然后使用JQuery中的.serializeObject（）方法将它们转换为JSON对象，然后将它们压入数组。但是我不知道如何将这种错误推到mongoDB

这是我的gym.hbs文件

<div id ="createWorkout" class="hiddenWorkout workoutCreator">
      <form id="exerciseForm" class="gymFormPadding" action="/dashboard/gym" method="POST">
    <div id="exerciseInput" class="form-group" style="display:flex;width:100%">
        <input id="exerciseName" class="form-control" type="text" name="name" placeholder="Exercise Name" value=""/>        
        <input id="exerciseSets" class="form-control" type="number" name="sets" placeholder="Sets" value=""/>        
        <input id="exerciseReps" class="form-control" type="number" name="reps" placeholder="Reps" value=""/>        
        <input id="exerciseWeight" class="form-control" type="number" name="weight" placeholder="Weight" value="" /> 

      </div>
      </form>
      <div id="newExerciseAdd"></div>

    <input type="hidden" name="_csrf" value="{{cybersecurity}}">           
    <button type="button" class="btn btn-primary" id="addExerciseAdd">Add New Exercise</button>               
    <button id="submitWorkout" type="submit"  class="btn btn-primary"  name="upload">Submit Workout</button>     

    </div>

这是负责操作的JQuery

  var counter = 1;
  $(document).ready(function(){
        $("#createWorkout").click(function(){
            $(".hiddenWorkout").removeClass('hiddenWorkout'); 
            $("#createWorkout").hide();
        });
    });

    $(document).ready(function(){
      var i = 0;
        $("#addExerciseAdd").click(function(){
          if(i<9){
            $("#exerciseForm").clone().appendTo("#newExerciseAdd");
            i++;
            $("#newExerciseAdd #exerciseForm").attr("id","exerciseForm"+i);
            $("#newExerciseAdd #exerciseInput").attr("id","exerciseInput"+i);
            $("#newExerciseAdd #exerciseName").attr("id","exerciseName"+i);
            $("#newExerciseAdd #exerciseSets").attr("id","exerciseSets"+i);
            $("#newExerciseAdd #exerciseReps").attr("id","exerciseReps"+i);
            $("#newExerciseAdd #exerciseWeight").attr("id","exerciseWeight"+i);
            counter++;
            }

        });

    });


   $(document).ready(function(){
      var array = [];
      var object;
      var exerciseNo = exerciseNo;
        $("#submitWorkout").click(function(){
          $("#exerciseForm").attr("id","exerciseForm0");
          $("#exerciseInput").attr("id","exerciseInput0");
          $("#exerciseName").attr("id","exerciseName0");
          $("#exerciseSets").attr("id","exerciseSets0");
          $("#exerciseReps").attr("id","exerciseReps0");
          $("#exerciseWeight").attr("id","exerciseWeight0");
          for(var i=0;i<counter;i++){
          object=$("#exerciseForm"+i).serializeObject();
          array.push(object);
          }
        });
        console.log(array);
    });

这是我的controller.js

const mongoose = require('mongoose');
const Gym = require('../models/gym');




exports.getGymPage = async (req, res) =>
{
    let coachStatus = req.user.userType;
    let teamID = null;
    if(res.locals.team){teamID = res.locals.team._id}   
    let exercises = await Gym.find({teamId:teamId});
    res.render('/dashboard/gym.hbs',{title: "Gym",exercises : exercises, coachStatus : coachStatus, cybersecurity: `${req.csrfToken()}`});
};

exports.addExercise = (req, res) =>
{
    const exercise = new Gym({teamID:res.locals.team._id, name: req.body.exerciseName,sets:req.body.exerciseSets,reps:req.body.exerciseReps,weight:req.body.exerciseWeight,cybersecurity: `${req.csrfToken()}`}).save();
    res.redirect('/dashboard/gym');
}

这是我的models.js

const mongoose = require('mongoose');
const { Schema } = mongoose;

const gymSchema = new Schema({
    teamID : {
        type: mongoose.Schema.ObjectId
    },

exercises:[{
    name :{ type:String, require: true},
    sets : [],
    reps : { type: Number, require: true},
    weight : { type: Number,},

}]
});

module.exports = mongoose.model('Gym', gymSchema);

我推送文件的方法完全荒谬吗？我觉得自己在转圈，无所适从。有更好的方法吗？
请原谅我最可能的可怕代码，我才刚刚起步。谢谢！

MongoDB应该知道它是一个数据数组。您是否尝试过通过以下方式来访问练习：

const exercise = req.body.exercise[0].name;
const exerciseData = JSON.parse(exercise);

然后进行推送，您可以只使用常规array.push 我不完全了解您要做什么，但是希望对您有所帮助...

如何将JSON对象数组发布到mongodb上？
