从M0ngo DB中深度嵌套的对象填充详细信息

问题描述

对于可能需要阅读的大量信息，首先道歉。

我试图使其简洁和相关。

我有三个收藏集-RawMaterial，BasicRecipe和Recipe。

数据流：基本配方是原材料的组合，而配方则是原材料和基本配方的组合。我正在突出显示我使用参考模型的部分模型。

基本食谱模型：

 details: [
    {
      quantityInRecipe: {
        type: Number
      },costOfRawMaterial: {
        type: Number,default: 0
      },rawmaterialdetails: {
        type: mongoose.Schema.ObjectId,ref: 'RawMaterial'
      }
    }
  ],

食谱模型：

  rawMaterialDetails: [
    {
      quantityInRecipe: {
        type: Number
      },details: {
        type: mongoose.Schema.ObjectId,basicRecipeDetails: [
    {
      details: {
        type: mongoose.Schema.ObjectId,ref: 'BasicRecipe'
      },unitInRecipe: {
        type: Number
      }
    }
  ]

在向客户端发送数据时，我需要填充3件东西。

食谱中的rawMaterialDetails
食谱中的basicRecipe详细信息
基本食谱中的rawMaterialDetails

我正在调用以下函数来填充数据。

exports.getAllRecipies = factory.getRecipe(
  Recipe,'rawMaterialDetails.details','basicRecipeDetails.details','basicRecipeDetails.details.details.rawmaterialdetails'
);

exports.getRecipe = (Model,popOption1,popOption2,popOption3) =>
  catchAsync(async (req,res,next) => {
    //console.log(Model);
    let filter = {};
    let selectFields = {};
    let features = Model.find(filter);

    if (popOption1)
      features = Model.find(filter)
        .populate(popOption1)
        .populate(popOption2)
        .populate(popOption3);

    // const doc = await features.query.explain();

    const doc = await features;

    // SEND RESPONSE
    res.status(200).json({
      status: 'success',results: doc.length,data: {
        data: doc
      }
    });
  });

通过此操作，我可以填充rawMaterialDetails和basicRecipeDetails。

我需要帮助来填充basicRecipeDetails中的rawMaterialsDetails。

这是我得到的结果的快照：

                    {
